The northern area of Tertiary rocks is made up of five formations which strike nearly east-west and dip gently northward. The younger formations overlap to the east so that at the eastern end of the nortli shore of the island only the Qucbradillas, the uppermost Tertiary formation, is present, while in the northwestern part of the island all five formations arc found. In order of descending age, these formations are the Quebradillas, the Los Puertos, the Cibao, the Lares, and the San Sebastian, the basal part of which, sometimes called the Collazo shale, lies unconfomiably on the Cretaceous basement rocks. The Southern area of Tertiary rocks includes two formations, an older one, the Juana Diaz, which probably corresponds in age to the San Sebastian of the north shore, and a younger form,ation, the Ponce, which probably is the equivalent of several of the north shore formations. The exact position of these various formations within the Tertiary is still not well substantiated, although their local relationships are * Professor of Geology, laciiana University. 1 Associate Professor of Geology, Smitli Collegfl.

For the present, we are accepting the age assignments made by Meyerhoff in his recent work on the geology of Porto Rico.^ North Shore Thickness Lower Miocene Quebradillas limestone 700-1500 Los Puertos Umestone 600-1000 Upper Oligocene Cibao limestone 250-1000 Lares limestone 1200-1300 Middle Oligocene San Sebastian formation 700 The Ponce formation of the south shore is considered upper Oligocene and lower Miocene in age. Its thickness is about 2,000 feet, while the underlying Juana Diaz is reported as up to 3,000 feet in thickness. CHARACTERISTICS OF THE FAUNA The total foraminiferal assemblage from the Tertiary of Porto Rico represents 25 families, 99 genera with 275 species and varieties, 88 of which are new. With the exception of the very small fauna from the Lares formation, the north shore formations are all of about the same size. The Ponce formation of the south shore is thought to represent a greater stratigraphic interval than any single one of the north shore formations and this idea is supported by the greater size of the Ponce fauna,—both as to number of families and as to number of genera and species.

The percentages for the Ponce formation are likewise of rather little significance, except as they show that the Ponce formation covers a wider stratigraphic range than any one of the north shore formations, and that it contains elements which may be correlated with the stratigraphic horizon of each of those formations. The percentages for the north shore formations show that they have rather closely related faunas, the smallest percentage of cor- relation being 23% between the Cibao and Los Puertos formations. In sharp contrast with the figures given above, are figures for the comparison of the Porto Rican formations with Oligocene and Miocene faunas from other areas in the gulf coast and West Indian region. In no case, except for the Ponce formation, was a per- centage of more than 14% discovered, although analyses were made with several faunas, among them the Alazan of the Tampico region in Mexico^; the lower Oligocene of Cuba^; the Oligocene of Ecuador^; the Miocene of eastern United States^; the middle Miocene of Buff Bay, Jamaica^; the middle Miocene of Haiti"^; the middle Tertiary Carapita formation of Venezuela^; the Tertiary of Trinidad^; and others. The Porto Rican faunas seem, therefore, to be in part provincial, in part pelagic, but in most part cosmopolitan and long ranging. With a few exceptions, which will be mentioned under the discussion of the various formations, they cannot be closely correlated with any faunas as yet published. Available data on depth distribution^^ of the various families which predominate in the Porto Rican formations lead us to postulate its accumulation at relatively shallow depths.

The presence of numerous Uvigerinidae and Nodosariidae at certain localities of the Ponce formation indicates that the south shore formation was deposited, in part, at greater depths. Certain characteristics of each fauna should be mentioned. In the San Sebastian formation, 69% of the species belong to only four families: 39% to the Miliolidae and Soritidae combined; 15% to the Nonionidae; and another 15% to the Rotaliidae. Many of these species are common or even abundant, so that more than 69% of the fossils found would fall in these four families. These percentages, and the presence of Camerinidae and Orbitoididae, seem to agree with conditions at Norton's Zone A, with depth of to 5 fathoms. In the Lares formation, 5 of the 10 species are milioloids, 2 are species of Elphidiurrij and 2 are rotaloids. In the Cibao formation, the dominant family is the Rotaliidae which includes 30% of the total number of species. The Nodosariidae are next with 12% and the Nonionidae third with 11%. The absence of the Soritidae, and the presence of only five species of milioloids, but several species of Uvigerinaj suggest accumulation at depths compar- able to Norton's Zone B which extends from 5 to 60 fathoms. Norton finds none of the uvigerine species at depths of less than 60 fathoms, so it seems probable that depth conditions were near the upper limit of 60 fathoms. The presence of Elphidium and Miogypsinoides is, however, suggestive of more shallow conditions than that indicated by the rest of the fauna. The Los Puertos fauna is dominantly porcelaneous, with 53% of the species belonging to the Miliolidae and Soritidae. The Rotaliidae with 9 species, or 19%, are second, and the Nonionidae with 6 species, or 13%, are third. This distribution is almost identical with that of Norton's zone A, with depth to 5 fathoms. The Quebradillas formation can be assigned to Norton's zone B, with depth 5 to 60 fathoms. The Miliolidae and Soritidae constitute 25% of the number of species, the Rotaliidae another 25%, and the Nonionidae 11%. Since several species of Elphidium are present, it is probable that the depth of deposition was about 16 fathoms, since Norton found that Elphidium is rare below that depth. The Ponce fauna is unusually large and upon close inspection it is found to contain elements of both deep and shallow water faunae: SAN JUAN GEOLOGIC MAP OF PUERTO RICO SCALE KILOMETERS =:p ^ Ol e346 lO 15 MILES AFTER H.A.MEYERHOFP 1933 T^ LEGEND QUATERNARY TERTIARY NORTH COAST QUEBRADILLAS LOWER MIOCENE- LOS PUERTOS LOWER MIOCENE E'iGURE 1.

Smaller percentages, but of importance in the determination of ecologic conditions, are the Chilostomellidae with 4 species, the Globigerinidae with 7 species, the Cassidulinidae with 4 species, the Nonionidae with 9 species, and the Orbitoids with 3 species. A deep water environment such as Norton^s zone D is suggested by the 23% of Nodosariidae, the 8% of Uvigerin- idae, and the presence of Chilostomellidae, Globigerinidae, and Cas- sidulinidae. But a much shallower environment is indicated by the presence of orbitoids and by the presence of Archaias and PeneropUs, ''which are almost never found below 60 fathoms." AGE OF THE FORMATIONS At the initiation of this study it was hoped that new light could be thrown on the exact age of the Porto Rican Tertiary formations and on their correlation with other West Indian and gulf coast localities. The fauna as a whole is a large one and that of the Ponce formation particularly so, but there is a surprisingly low percentage of correla- tion with other described faunas from the same general region. A formation by formation tabulation of the species and their strati- graphic ranges (table 4) has been made and from these tabulations the age of all the Porto Rican formations is seen to lie in the Oligocene or Miocene, evidently not lower than lower Oligocene, nor higher than middle Miocene. This corroborates the age determinations which were made by Meyerhoff in 1933. The presence of large numbers of Elphidium in all except the very youngest part of the Tertiary succession, namely the Quebradillas and the upper part of the Ponce, is unusual since Elphidium is rarely found in any abundance below the Miocene. Other constituents of these faunas, however, are definitely Oligocene,—^namely the orbitoids and camerines. These are found in all except the Quebradillas and the upper part of the Ponce formation. A middle Oligocene age for the San Sebastian is indicated by its more than 10% correlation with species of the Byram of southeastern United States, and by the presence of significant middle Oligocene index fossils, such as Botalia choctawensiSy Heterostegina antilleay Miogypsinoides complanataj and Lepidocyclina cf. parvula. The Lares and Cibao formations have fewer reliable index fossils. The middle and upper Oligocene index fossil Miogypsinoides com- planata is abundant in the Cibao formation, so it seems probable that these formations, which overlie the San Sebastian, are of upper Oligocene age, as postulated by Meyerhoff. 286 SCIENTIFIC SURVEY OF PORTO RICO Meyerhoff (1933) assigns a lower Miocene age to both the Los Puertos and the Quebradillas formations. The fauna of the Los Puertos is so totally unlike any other known fauna that we can draw no definite conclusions as to its age, although the presence of Miogypsinoides complanata suggests an upper Oligocene rather than a lower Miocene horizon. The Quebradillas formation, however, seems to be late lower Miocene or possibly early middle Miocene in age. This is indicated by the absence of Oligocene markers, namely the larger foraminifera, and by the fairly high degree of correlation between the Quebradillas fauna and the fauna of several middle Miocene localities in the West Indian region,—^namely 12% with the lower Miocene of Trinidad, 14% with the middle Miocene of Haiti, and 14% with the middle Miocene of Jamaica. Evidence of the Oligocene age of some of the Ponce was afforded by the comparisons made with other faunas. The percentage of corre- lation with Oligocene faunas ranged from 15 to 20% ; the percentage of correlation with middle Miocene faunas ranged only from 10 to 12%. The foraminiferal fauna of the Ponce therefore shows both Oligocene and Miocene elements, but the Oligocene trend seems more pro- nounced, at least for the lower part of the Ponce which is the part of the Ponce most abundantly represented in our collections. Some of the Ponce is as old as lower Oligocene. The exact per- centage of correlation with Oligocene faunas were as follows: 18% with the lower Oligocene of Cuba, 20% with the lower Oligocene of Mexico described by Nuttall, 16% with the lower Oligocene described by Dorr from the Alazan (1933. Jour. Paleont. 7) 15% with the Carapita of Venezuela, of probable upper Oligocene age. A number of specialized forms which occur only in beds of lower Oligocene age furnish additional proof. Among these are Verneuilina mexicana, Dorothia cylindrica, VaginuUna mexicana, Antillesina marielensis, Valvulineria palmarealensis, Rotalia mexicana mecatepecensis , Uvi- gerina vicksburgensis, Siphogenerina mexicana, and others. It is probable that the middle and upper Ponce are much younger than lower Oligocene. The 10 and 12% correlations with middle Miocene faunas suggests that upper Ponce is about lower Miocene in age. An examination of the known stratigraphic ranges of the Ponce species shows two times of most abundant species,—namely the lower Oligocene in which 69 of the Ponce species occur, and the middle Miocene in which 51 of the Ponce species occur. Faunas of other ages include only 25 or fewer of the species which occur in the Ponce (table 4).

A. Meyerhoff, who, by his careful collection of material from the many localities enumerated above, has made possible the prosecution of this work. To him we owe, also, our knowledge of the relative stratigraphic position of the various collecting localities. The figures were drawn by the senior author, J. J. Galloway. Valuable assistance in shading the figures was furnished by Frances Beede, Frederick P. Schweers, and J. Bernard Martindale. Drafting of the Porto Rican locality map was done by Frederick P. Schweers. We are grateful for the substantial grants from the research funds of Smith College and Indiana University for assistance in making the drawings. All of the types are catalogued and deposited in the Paleontological laboratory at Indiana University.

Rare at A86 of the Cibao formation. 302 SCIENTIFIC SURVEY OF PORTO RICO We are following the generally accepted usage of restricting the name Q, seminulum (Linne) to those short, ovate quinqueloculines with subangular edge. Quinqueloculina apiculata new species Plate 2, figures 2a-c Test about twice as long as wide, % as thick as wide; periphery- rounded; chambers distinct, lengthening rapidly, somewhat inflated, distal end of last chamber with a short blunt apicule; sutures distinct, moderately depressed; surface of holotype poorly preserved; aper- tural end of last chamber extended into a neck; aperture terminal, circular, with a narrow, simple tooth. Length, 0.49 millimeter; width, 0.23 millimeter; thickness, 0.14 millimeter. Holotype No. 3962, locality L6C, San Sebastian formation. Very rare at L6C of the San Sebastian formation. This species has resemblance to Q, laevigata, but has a definite, distinctive neck. Quinqueloculina audacula new species Plate 1, figures 7a-c Test somewhat longer than wide; chambers polygonal in transverse section, with conspicuous angles or carinae; back flat or slightly con- cave between the carinae; sutures distinct, slightly depressed; aper- ture round, with simple tooth, at the end of a short, round neck.

Length, 0.81 millimeter; width, 0.38 millimeter; thickness, 0.25 millimeter. Plesiotype No. 3964, locality L6C, San Sebastian formation. Common at L6C, LlC, and L2C; rare at L4C and L5C of the San Sebastian formation. Although named by d'Orbigny in 1826, this species was a nomen nudum until 1839, when it was jBgured by d'Orbigny in his paper on the Foraminitera of the Canaries. In 1905, d^Orbigny's original figure of the species was published by Fornasini. This figure differs from that of Q. laevigata in the Canaries paper, but the earlier pub- lished figure, that of the Canaries paper, is necessarily taken as the type figure. Quinqueloculina maculata new species Plate 2, figures 3a-c Test oval in side view, subquadrate in end view, length nearly twice breadth, thickness % breadth; periphery angled; chambers distinct, subtriangular in cross section; sutures only slightly depressed; wall of all chambers finely punctate; apertural end not produced; aperture oval. Length, 1.03 millimeters; width, 0.63 millimeter; thickness, 0.45 millimeter. Holotype No. 3965, locality L6C, San Sebastian formation. Rare at L4C; common at L6C of the San Sebastian formation. This species is distinctive in its ornamentation. It much resembles Massilina jacksonensis Cushman (1933. Contr. Cushman Lab. Foram. Res. 9) but it has no spiroloculine stage and, in any case, is less compressed. Q. jamaicensis Cushman and Jarvis which was described from the Eocene of Jamaica (1931. Contr. Cushman Lab. Foram. Res.) is more compressed and has pits arranged in definite nearly longitudinal lines. Quinqueloculina philippi Reuss Plate 2, figures 4a-d Quinqueloculina philippi Reuss (1856) Sitz. k. Akad. Wlss. Wien 18: 252. pi. 9, figs. 87a-d. Upper Oligocene, Germany. Test very slender and elongate, compressed, narrowly oval in end view; edge angled with the suggestion of a keel; length nearly three times the width; width more than twice the thickness; chambers tubular, of fairly uniform diameter; aperture terminal, round, at the end of a definite neck, tooth not seen. Length, 0.73 millimeter; width, 0.26 millimeter; thickness, 0.11 millimeter. 304 SCIENTIFIC SURVEY OF PORTO RICO Plesiotype No. 3966, locality A79, Los Puertos formation. Very rare at A79 and A91a of the Los Puertos formation. This species is close to Q. angustissima which was described by Reuss from the middle Miocene and which occurs also with Q. philippi in the upper Oligocene. It differs from Q. angustissima in having a distinctly angled edge. The Porto Rican form is slightly more slender than the original figure of Q. philippi.

HAUERINA d'Orbigny 1839 Hauerina sansebastianensis new species Plate 5, figures 3a-c, and 4a--c Test discoidal, nearly equally biconvex and biumbilicate, immature specimens relatively more convex; periphery subacute; 4 chambers in last whorl of the adult, 3 in immature forms ; chambers subtriangular in shape, increasing rapidly in size, occasionally involute, more com- monly with a few milioline chambers showing in the umbilical region ; sutures sharply depressed; surface smooth; aperture in the young an elongate slit with bluntly serrate margin extending the full length of the last septal face, in the adult a tuberculate trematophore. Adult specimen diameter, 0.84 by 1.05 millimeters; maximum thickness, 0.37 millimeter. Holotype No. 3925a, Paratype 3925b, locality L6C of the San Sebastian formation. Common at L6C of the San Sebastian formation. This species resembles H. compressa d^Orbigny from the Miocene of the Vienna Basin, but is thicker and differs in character of the aper- ture and in shape of the chambers. It differs from H. bradyi Cush- man (1917. Bull. U. S. Nat. Mus. 71 (6)) in its greater thickness and different shape of the chambers. Family SORITIDAE Ehrenberg 1840 DENDRITINA d'Orbigny 1826 Dendritina preelegans new species Plate 5, figfres 5a, b Test compressed, biumbilicate; subcircular to oval in side view, close coiled in the early part tending to become evolute in the later part; edge rounded; chambers about 12 in the last whorl, short and wide, enlarging gradually; sutures distinct, little depressed; wall ornamented with fine longitudinal striae which are not continuous from chamber to chamber; aperture an elongate, oval dendritic open- ing in the middle of the last septal face. Diameter, 1.00 by 1.33 milli- meters; thickness, 0.33 millimeter. 316 SCIENTIFIC SURVEY OF PORTO RICO Holotype No. 3889, locality A79, Los Puertos formation. Common at A79 of the Los Puertos formation. This new species is closely related to Peneroplis elegans d^Orbigny from the Recent of Cuba, but differs in the character of the aperture which is dendritic and not perforate. It differs from Dendritina antillarum d'Orbigny, also from the Recent of Cuba, in that it is less involute and the aperture is different. The aperture of D. preelegans is more regularly dendritic and it is restricted to an oval area in the center of the apertural face, not occupying the entire apertural face as it does in D. antillarum.

Test biconvex near the center, rest of the test explanate, very thin; edge truncate; chambers numerous, short and very wide, early ones involute to the center, later ones tending to become annular, the arc of the chamber being around 120 degrees in the young chambers and 180 or more in the adult chambers; aperture consisting of numerous large, closely but irregularly arranged pores covering the entire aper- tural face. Diameter, 1.56 by 2.06 millimeters; thickness, 0.17 milli- meter. Plesiotype No. 3868, locality P258, Ponce formation. Abundant at L6C of the San Sebastian formation. Rare at A79 of the Los Puertos formation, and at F359 of the Quebradillas forma- tion. Rare at P251 and P434; common at P258 and P259 of the Ponce formation. Many authors have discarded this species and have considered these forms as adult forms of the species A. angulatus. The Los Puertos material shows specimens of two types, each of which is sufficiently distinct to merit specific rank. 318 SCIENTIFIC SURVEY OF PORTO RICO A. aduncus differs from A. angulatm in the following ways: 1. larger diameter 2. thinner test, both relatively and actually 3. general appearance : angulatus is nautiloid with angled edge, aduncus is ex- planate with truncate edge 4. the arc of chamber width is about 180° (120° minimum) in aduncus and only 90° in angulatus 5. the last chambers of angulatus are involute to the umbiHcus It seems obvious that these cannot be adult forms of A, angulatus^ particularly on points 2-5 above.

GALLOWAY AND IIEMINWAY, TERTIARY FORAMINIFERA 319 Family TROCHAMMINIDAE Schwager 1877 TROCHAMMINOIDES Cushman 1910 Trochamminoides approximatus NEW species Plate 6, figures la, b Test small, subcircular in side view, the two sides nearly exactly alike, biconcave, asymmetrically planispiral, composed of about 5 volutions, each volution embracing about half of the previous volu- tion, and increasing gradually in thickness; periphery moderately lobulate; edge regularly rounded; chambers about 12 in the last volution, increasing gradually in size; sutures distinct, slightly de- pressed, narrow, mostly nearly straight, some curved slightly outward and backward, discernible from the proloculum outward; the concamer- ation is not due to irregular constrictions but due to normal septation ; wall white, very finely arenaceous, consisting of very fine, angular grains of calcite bound together with a small amount of white, cal- careous cement; surface finely granular; aperture a narrow arch at the base of the septal face. Diameter, 0.66 millimeter; thickness, 0.12 millimeter. Holotype No. 4064, locality A91a, Los Puertos formation. Rare at A91a of the Los Puertos formation. This species differs from T, proteus (Karrer), from the Cretaceous of the Vienna Basin, in lacking an early tubular portion, in having a greater number of whorls, more nearly planispiral symmetry, definite septation and small aperture. It also differs from Recent specimens identified with T. proteus Brady (1884. Rep. Voy. Challenger Zool. pi. 40) in the planispiral symmetry of the early spire, more regular concameration, and the smaller aperture, as well as the smaller size and greater number of volutions. It is quite unlikely that the large number of forms from Jurassic, Cretaceous, Tertiary, and Recent ages which have been identified with T. proteus (Karrer) actually belong to that species.

Test large for the genus, tetrahedral, an inverte(i three-sided pyramid in shape, initial end pointed, the sides rapidly diverging, losing the three-sided form so that the apertural end is subcircular in shape; chambers triserially arranged, rapidly increasing in size; sutures depressed; wall coarsely arenaceous with much calcareous cement; aperture along the inner margin of the last chamber with a large projecting tooth or valve. Height of test, 1.2 millimeters; diam- eter of apertural end, 1.01 by 1.20 millimeters. Plesiotype No. 4026, locality L6C, San Sebastian formation.

VALVULAMMINA Cushman 1933 Valvulammina cornucopia new species Plate 6, figures 4a-c Test shaped like a small, twisted cornucopia, widening very rapidly from the pointed initial end; spire of medium height, last whorl con- stituting about half the height of the test; 4 to 5 chambers in the last whorl (in no case as many as 6), chambers loosely appressed, in- flated, increasing rapidly in size in width, but not in length or height; sutures distinct, depressed; wall medium coarsely arenaceous, smoothly GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 321 finished with much calcareous cement; aperture large, at the base of the last septal face, with short, wide, valvular tooth; apertural face large, flaring, constituting about half of the last whorl on the ventral side of the test. Height, 0.70 millimeter; diameter of apertural end, 0.90 by 1.13 millimeters. Holotype No. 4025, locality L6C, San Sebastian formation. Rare at L4C and L6C of the San Sebastian formation. Common at P258 of the Ponce formation. This species is very close to Valvulammina deformis (d'Orbigny) as figured by Fornasini (1904. Mem. R. Accad. Sci. Istit. Bologna Sez. Sci. Nat. VI. 1) from the Eocene of France, but the test is higher, the chambers are fewer in each whorl and do not increase as rapidly in width, the last chamber is not as large, and the apertural valve is less well formed. It differs from V. affinis Cushman and Bermudez from the Eocene of Cuba (1937. Contr. Cushman Lab. Foram. Res. 13) in having fewer chambers in the last whorl, and more depressed sutures.

Length, 0.77 millimeter; maximum diameter, 0.60 millimeter. Plesiotype No. 4031, locality P2, Ponce formation. Rare at P2 and P3 of the Ponce formation, and at A93 of the Quebradillas formation. We have several complete adult specimens of this species, none of which show an early 4 or 5 chambered stage or an adult 2 chambered stage.

Test large, rather stout, sides and edges nearly parallel throughout most of the test; roughly hexagonal in cross section; chambers bi- serially arranged throughout, numerous, about 10 pairs, closely ap- pressed; chambers with distinct lobes at the basal border, one or two on each side of the test; sutures distinct, recurved adorally between the lobes ; wall rather coarsely arenaceous with much cement, smoothly finished; surface irregular due to the apically projecting lobes which form a series of deep indentations; aperture a low, elongate opening at the inner margin of the last-formed chamber in a slight re-entrant. Length of holotype, 1.77 millimeters; width, 0.81 millimeter; thick- ness, 0.61 millimeter. Holotype No. 4051, locality A43a, Cibao formation. Rare at A43a of the Cibao formation. Forms similar to this species have been found many times and have usually been confused with Reuss's species, which he called Plecanium rugosum (1869. Sitz. Akad. Wiss. Wien 59). Reuss shows a form with fairly straight sutures without the lobate extensions which characterize T. indenta. Brady (1884) gives two figures of a form which he calls Textularia rugosa (Reuss), neither of them being T. rugosa as described and figured by Reuss. The forms figured by Brady, with the lobate projections and irregularly excavated cham- bers seem to be identical with that found by us in the Cibao forma- .rtion, for which we here propose the name indenta, Cushman proposed the name Gaudryina rugulosa (1932. Bull. U. S. Nat. Mus. 161 (1)) and placed both of Brady's figures in synonymy, but it is evident from Cushman's type figure that he had in mind a form in which the test has conspicuous, nearly horizontal corrugations separated by "excavated" areas. It is probable that the genus is Textularia^ since a section of the earliest part of the test showed nothing but biserial chambers. The sections made show no indication of septula, so the species cannot 332 SCIENTIFIC SURVEY OF PORTO RICO be Textulariella, although it looks very much like Hofker^s figure of Textularia rugosa.

Length, 0.55 millimeter; diameter, 0.41 millimeter. Plesiotype No. 3951, locality A86, Cibao formation. Rare at A86 of the Cibao formation and P254 of the Ponce forma- tion. Although forms which are identified as Lagena strumosa Reuss occur in the Porto Rican material, they do not come from the same localities as the specimens of G. gallowayi and, in any event, it seems im- probable that they could be young specimens of G. gallowayi as was stated by Cushman in 1929 for the following reasons: 1. The shape of the apical end of the test is different in the two forms, that of G. gallowayi being much more tapering. 2. The aperture is distinctly radiate in G. gallowayi but is not in L. strumosa.

Gulf of Mexico, Caribbean Sea, and off northeastern U. S. Dentalina communis Cushman & Cahill (1933) U. S. Geol. Surv. Prof. Pap. 175A: pi. 5, flg. 2. Miocene, Florida. Test elongate, slender, slightly tapering, slightly curved, circular in cross section; chambers numerous, about 7 in the complete test, those near the apertural end inflated a little; sutures oblique, slightly 340 SCIENTIFIC SURVEY OF PORTO RICO depressed, more so on the convex edge of the test; surface smooth, un- ornamented; aperture radiate, eccentric, nearer the concave side of the test. Length, 1.55 millimeters; diameter, 0.28 millimeter. Plesiotype No. 3895, locality P254, Ponce formation. Rare at P2, P254, and P255 of the Ponce formation. Many forms which have been referred to D. communis (d^Orbigny) probably belong to D. advena. The features of d'Orbigny^s species are well shown by Fornasini in his reproduction of d'Orbigny's un- published figure (1898. Mem. R. Accad. Sci. 1st. Bologna V. 7) in which the test has 12 chambers and an apical spine. D. advena bears a strong resemblance to D. debilis Hantken (1875. Mitt. Jahr. k. ungarn geol. Anstalt 4 (1)).

Test elongate, very slightly tapering; chambers about 5, subglobular, the early ones more closely appressed than the later ones; early sutures obscure, nearly flush with the surface of the test, later sutures depressed; surface conspicuously ornamented, the early chambers ornamented by discontinuous longitudinal costae, about 7 visible on each side of the test, the next chambers with spinose projections developing at the apical ends of the interrupted costae, the last cham- ber with a series of fine pustules in longitudinal lines; aperture round, terminal and slightly produced, not definitely radiate. Length, 1.00 millimeter; diameter of last chamber, 0.30 millimeter. Plesiotype No. 3892, locality P2, Ponce formation. Very rare at P2 of the Ponce formation. Dentalina halkyardi ponceana new variety Plate 9, figures 11a, b Test elongate, tapering, slightly arcuate, circular in cross section; apical end blunt, with a short, stout spine; about 8 chambers in the test, increasing slowly in size, early chambers slightly wider than long, last chamber nearly equidimensional ; first few chambers very slightly inflated, sutures nearly flush with the surface; later chambers in- flated, widest near the basal part of each chamber, separated by de- pressed sutures; surface ornamented by 12-14 diagonal costae which are continuous on the first 3-4 chambers and which extend to the GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 341 final chamber ; costae become discontinuous after the first 4 chambers with apically pointing spines or prickles on the costae of penultimate chamber and finally break up into spines on the lower two-thirds of the last chamber, apertural third of the final chamber being un- ornamented; apertural end of final chamber slightly produced, aper- ture eccentric, round and radiate. Length, 2.37 millimeters; diameter, 0.53 millimeter. Holotype No. 3893, locality P3, Ponce formation. Rare at P2, P3, and P255 of the Ponce formation. This variety differs from D. halkyardi Cushman (1933. Contr. Cushman Lab. Foram. Res. 9) in the strongly oblique character of the longitudinal costae, the presence of an apical spine, and the presence of separate spines on the final chamber only. Dentalina hiUaeformis new species Plate 9, figure 12 Nodosaria pauperata Cushman (not d'Orbigny) (1923) Bull. U. S. Nat. Mus. 104 (4) : pi. 14, fig. 13. Recent off northeastern U. S.

Test flask shaped, nearly circular in cross section, body of test subcylindrical ; neck moderately long, gradually contracted from the body of the test; surface ornamented with 10 medium sized costae which begin at or near the apex and extend up onto the beginning of the neck; upper part of neck unornamented ; apical end broadly rounded; aperture simple, round, terminal. Length, 0.42 millimeter; diameter, 0.17 millimeter. Holotype No. 3926, locality L6C, San Sebastian formation. Rare at LlC, L2C, and L6C of the San Sebastian formation, and at P2 of the Ponce formation. This species differs from L. amphora Reuss (1862. Sitz. k. Ak. Wiss. Wien 46 (1)) in having fewer costae, a shorter neck, and a more abruptly tapering apertural end. L. raricosta (d^Orbigny) (1839. Voy. Amer. Merid. 5 (5) : Foraminiferes) is less elongate and has a shorter neck. L. tenuis (Bornemann), as designated above, is similar neither in ^hape nor ornamentation.

Test large, circular in side view, gently biconvex, with umbonal bosses of clear shell material; edge acute with thin carina of clear shell material; chambers 12-13 in the adult whorl, short and wide; sutures flush with the surface, limbate, radial near the umbonal re- gion, curving more and more to the periphery; aperture at the outer margin of the last septal face, radiate outside, with a slit extending down onto the septal face. Diameter, 1.7 millimeters; thickness, 0.6 millimeter. Plesiotype No. 3976, locality P2, Ponce formation. Rare at P2 of the Ponce formation. Our specimens differ from typical R. iota in lacking the wide, sharp keel. They are much like the Florida Miocene specimens.

Miocene, Jamaica. 350 SCIENTIFIC SURVEY OF FORTO RICO Test biconvex, umbonate with relatively small umbonal filling of clear shell material where sutures converge; edge angled with keel of clear sliell material about 0.17 millimeter wide; 5-6 chambers in last whorl, subtriangular in shape, enlarging gradually; sutures curved, broadly limbate, flush with the surface; aperture a slit just below the outer point of the last chamber, radiate on the outer edge. Average dimensions: diameter, 1.24 by 1.48 millimeters; thickness, 0.68 milli- meter. Plesiotype No. 4096, locality P3, Ponce formation. Common at P2, P3, and P255 of the Ponce formation. Robulus planulus NEW species Plate U, figures 14a, b Test small, compressed, nearly flat on the sides, biumbilicate, con- sisting of about 2 whorls of chambers, all visible on both sides of the test; chambers 6 to 7 in the last whorl, enlarging gradually, slightly in- flated; sutures distinct, limbate, with limbation continuing along the periphery forming a narrow border, outside of which is a narrow, flat keel set off from the border by a square shoulder; surface smooth; septal face concave; aperture a narrow slit extending down into the septal face, finely but distinctly radiate outside, the throat of the aperture showing through the clear shell material. Diameter, 0.42 by 0.61 millimeters; thickness, 0.12 millimeter. Holotype No. 3979, locality A86, Cibao formation. Common at A86 of the Cibao formation. This pretty little species is distinctive in its much compressed test, and shouldered and flanged edge. This form might be placed in the genus Planularia by some students of Foraminifera, but that genus is evolute and triangular in side view and more like Vaginulina than Robidus, as an inspection of the type figure will demonstrate.

Test small, subcircular, strongly biconvex, involute beyond umbo; edge acute with narrow keel which narrows orad and disappears on the last chamber; chambers few, 4 or 5 in the last whorl; sutures flush with the surface, gently curved, bordered with clear shell ma- terial, meeting in the umbonal region but not making a boss; sur- GALLOWAY AND IIEMINWAY, TERTIARY FORAMINIFERA 351 face smooth; apertural face crescentic, concave; aperture a narrow triangular slit extending down into the septal face, finely radiate laterally. Diameter, 0.53 by 0.66 millimeter; thickness, 0.35 milli- meter. Plesiotype No. 3977, locality P254, Ponce formation. Rare at locality P254 of the Ponce formation. Golems description and figure are inadequate for certain recogni- tion of his species. Our specimens are smaller but seem otherwise identical. This species reminds one of Cristellaria crassa d'Orbigny (1846. Foram. Foss. Vienne), and the Cuban specimens referred to that species by Palmer and Bermudez (1936. Mem. Soc. Cubana Hist. Nat. 10: 252), which they say is "without any robuline slit'\ In our experience species of '^Cristellaria^' with a round aperture are extremely rare or probably nonexistent, excepting strongly evolute forms properly referable to other genera. All discoidal forms have robuline apertures. Robulus protuberans (Cushman) Plate U, figures 13a, b Cristellaria protuberans Cushman (1918) Bull. U. S. Nat. Mus. 103: 61. pi. 22, fig. 2. Lower Culebra formation, Oligocene, Panama Canal Zone. Test large, biconvex but thin; the umbonal region ornamented with large, round knobs; edge angled with prominent keel of clear shell material which narrows and disappears on the last chamber; chambers essentially planispiral in arrangement, tending to become evolute, 10 in the last whorl; chambers inflated, separated by deep, nearly radial sutures; aperture produced near the outer margin of the last septal face, radiate outside, with a small slit extending down onto the apertural face and becoming oval; apertural face flat, nar- rowly elliptical. Maximum diameter, 2.75 millimeters ; thickness, 0.30 millimeter. Plesiotype No. 3980, locality P2, Ponce formation. Very rare at P2 of the Ponce formation. The specimen figured is a little asymmetrical. It is interesting to note that the species which most closely resembles this unusual form of Robulus is Cristellaria karreri Rzehak from the Miocene of Czecho- slovakia. R. protuberans differs in that it has more chambers, a narrower keel, and is more evolute. Robulus subpapillosus (Nuttall) Plate 12, figures 2a, b Cristellaria subpapillosa Nuttall (1932) Jour. Paleont. 6: 12. pi. 1, fig. 12. Lower Oligocene, Mexico. 352 SCIENTIFIC SURVEY OF PORTO RICO Test biconvex, ovate in side view, tending to become evolute; edge acute, without distinct keel, but with thin, jHat, short, spinose projec- tions at the ends of most of the sutures; 9 to 10 chambers in the last whorl, increasing more rapidly in width than in length; sutures dis- tinct, depressed or flush with the surface between the last few cham- bers, slightly raised with beadlike ornamentation between the earlier chambers of the last whorl, the beads larger near the umbo; septal face flat, narrow; aperture at the outer margin of the last septal face, slightly produced, large, oval and coarsely radiate. Length, 1.28 millimeters; width, 0.9 millimeter; thickness, 0.44 millimeter. Plesiotype No. 4095, locality P3, Ponce formation. Rare at P3 and P255 of the Ponce formation. R. subpapillosa differs from R. gutticostatus (Giimbel) in that it has no keel. Although not figured, the forms referred to Cristellaria gutticostata by Palmer and Bermudez from the Lower Oligocene of Cuba probably belong to this species. They state that, ''specimens referred to this species differ from the type in the development of short, peripheral spines, frequently without an intervening flange" (1936. Mem. Soc. Cubana Hist. Nat. 10). Young specimens of R. subpapillosus are like R. brevispinosus (Nuttall) (1928. Quart. Jour. Geol. Soc. London 84). LINGULINA d'Orbigny 1826 Lingulina ponceana new species Plate 11, figures 11a, b Test moderately compressed; smoothly ovate, not lobulate, in side view, slightly longer than wide, apical and apertural ends equally rounded, greatest width midway of the test; biconvex in cross section, edge narrowly rounded with a border of clear shell material; chambers few, usually 4, increasing rapidly in size as added, the lower margin of each chamber slightly overhanging the preceding chamber along the pe- riphery; sutures flush with surface of test except for the last one which is slightly depressed; wall smooth and polished; aperture terminal, an elongate slit parallel to the compression of the test. Length, 1.50 millimeters; width, 1.27 millimeters; thickness, 0.63 millimeter. Holotype No. 3927, locality P3, Ponce formation. Rare at P3 of the Ponce formation. This species most closely resembles L. cubensis Cushman and Bermudez from the Eocene of Cuba (1937. Contr. Cushman Lab. Foram. Res. 13) but differs in its larger size, in the absence of a "distinct, sharp keel", and the absence of any coiled early stage.

Nearly all of the Porto Rican specimens are slightly asymmetrical. This is shown in figures by various authors and this slight degree of asymmetry seems to be permissible in the genus Nonion, since there is no umbilical extension of the last chamber on either side of the test. Nonion subgrateloupi new species Plate 14, figures 2a, b, and 3a, b Test of average size for the genus; ovate in side view, periphery smooth; elliptical in edge view; edge rounded, more sharply so in early portion of the last whorl; umbilici small, ornamented by about 30 rather small papillae; chambers 12-13 in the last whorl, elongate, increasing most rapidly in a radial direction, last few chambers tending to uncoil; sutures very little depressed, gently curved; wall smooth, polished, very finely perforate; apertural face convex, with slightly convex or nearly parallel sides, height nearly twice the width ; aperture a narrow arch at base of the apertural face. Length, 0.57 millimeter; width, 0.37 millimeter; thickness, 0.23 millimeter. Holotypes No. 3940a, b, locality L5C, San Sebastian formation. Rare at L4C; common at L5C of the San Sebastian formation. Abundant at A79 of the Los Puertos formation. Rare at P251; common at P259; abundant at P253 and P258 of the Ponce formation. This species is thicker than typical N. grateloupi (d'Orbigny) from the Recent of Cuba, and has distinctive papillate ornamentation in the umbilical region. There are obvious similarities between this and the topotype figures of N. elongatum (d^Orbigny) as figured by Cushman (1939. U. S. Geol. Surv. Prof. Pap. 191), but iV. sub- grateloupi has a more compressed test and less pronounced umbilical filling. PSEUDONONION Asano 1936 Pseudononion papillatum new species Plate 14, figures 4a-c Test asymmetrical, broadly oval in side view, narrowly oval in edge view; chambers arranged in a very low, nearly planispiral coil, early whorls showing on one side, umbilicate on the other side with GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 359 papillate filling of secondary shell material which extends out for a varying distance along the sutures; edge evenly rounded; periphery slightly lobulate; about ten chambers in the last whorl; sutures dis- tinct, gently curved, slightly depressed; wall very finely perforate; aperture a low arch with lip on the inner periphery at the base of the last septal face, not extending into the umbilicus. Diameter, 0.41 by 0.55 millimeter; thickness, 0.29 millimeter. Other specimens range up to 0.7 millimeter in diameter. Holotype No. 4072, locality A43a, Cibao formation. Abundant at A43a of the Cibao formation. Since the test is asymmetrical and therefore not Nonioriy and none of the chambers extend into the umbilicus as they do in Nonionella^ these specimens are referred to Asano's new genus, Pseudononion (1936. Trans. Paleont. Soc. Japan 15). The form resembles Globoro- talia except for the nonionine aperture.

Length, 0.30 millimeter; width, 0.21 millimeter; thickness, 0.12 millimeter. Holotype No. 3941, locality LlC, San Sebastian formation. Rare at L3C and L6C; common at LlC of the San Sebastian for- mation. This form has more chambers and is thinner than N. pauciloba Cushman (1935. Contr. Cushman Lab. Foram. Res. 11). It has fewer chambers and is less lobulate than N. auris (d'Orbigny) (1839. Voy. Amer. Merid.). It is not typical N, pseudo-auris Cole (1931. Fla. Geol. Surv.

Elphidium lens new species Plate 14, figures 10a, b Test rather large, subcircular in side view, periphery not lobulate; elliptical in edge view, thickness less than half the diameter, back narrowly rounded; umbilical region evenly umbonate and filled with clear shell material bearing 10-15 irregularly arranged subcircular pits; umbilical filling separated by a distinct, shallow, curved depres- sion from the chambers of the last half volution; chambers closely appressed, 28-30 in the last whorl; sutures not depressed at the periphery but depressed slightly toward the umbo, marked by 15- 20 septal bridges between the last 2 chambers on one side of the test; septal bridges very short, about % chamber in length, and only slightly elongate in direction of coiling enclosing elliptical depres- sions; septal bridges of successive sutures form lines that spiral out- ward from the umbonal region; aperture a series of pores at the base of the last septal face, and several pits on the last septal face. Di- ameter, 0.83 by 0.98 millimeter; thickness, 0.42 millimeter. Holotype No. 3905, locality L4C, San Sebastian formation. Abundant at L5C and L6C; common at L3C and L4C; rare at L2C of the San Sebastian formation. E. lens differs from E. craticulahtm (Fichtel & Moll) (1798. Test. Micr.) in the smaller size, fewer chambers, thinner test, rounded edge, smaller umbonal region, and more curved sutures. It is possible that Polystomella craticulata Cushman (not Fichtel & Moll) (1918. Bull. U. S. Nat. Mus. 103) from the Culebra formation of the Panama Canal Zone should be placed in synonymy with E. lens. The Panama Canal form seems to differ only in having about 40 instead of 28-30 chambers in the last whorl. E. lens differs from E. lanieri (d'Orbigny) from the Recent of Cuba in being relatively thinner and in being elliptical rather than diamond shaped in edge view, with smaller umbonal region and more chambers. It differs from E. chapmani Cushman (1936. Contr. Cushman Lab. Foram. Res. 12) in its elliptical not rhomboidal edge view, in its higher apertural face, and in its smaller test. 362 SCIENTIFIC SURVEY OF PORTO RICO Elphidium lobatum new species Plate 14, figures 8a, b Test small for the genus, nearly involute with a slight umbilicus, subelliptical in side view, early part of test much thinner than the later part where inflation of the last few chambers increases rapidly; periphery lobate; back broadly rounded; chambers numerous, 9-10 in the last whorl, increasing rapidly in size, inflated, last chamber becoming nearly circular in apertural view, except for the impressed zone of the previous whorl; sutures distinct, sharply depressed, smoothly curved, marked by a series of broad retral processes and 8--10 small semi-circular depressions; aperture a row of pores at the inner margin of the last septal face. Diameter, 0.17 to 0.45 milli- meters; thickness, 0.23 to 0.27 millimeters. Holotype No. 3906, locality A6, Lares formation. Rare at A6 of the Lares formation and at F359 of the Quebradillas formation. The specific name lobatum refers to the markedly lobate outline of the test in side view. This species differs from E. poeyanum in that the chambers are more inflated, the sutures are more depressed, the periphery is more lobate, and the shape of the apertural face is more nearly circular. Elphidium nautiloideum new species Plate 14, figures 5a, b Test small for the genus, nautiloid, sides nearly parallel in edge view, subcircular in side view, not lobulate, except very slightly in the last few chambers; back makes a parabolic curve with the sides of the test; umbilici about % the diameter of the test, depressed and papillate; chambers distinct, 12-15 in the last whorl; sutures slightly curved, radial, only a little depressed, marked by inconspic- uous, short retral processes and small oval depressions, 12-15 between the last two chambers on one side of the test; surface smooth; wall finely perforate ; height of the apertural face in median line about % the maximum width which comes in line with base of last septal face on the periphery; aperture a series of pores at the base of the last septal face, and a few scattered pores on the septal face. Aver- age specimen, 0.34 by 0.41 millimeter in diameter and 0.21 milli- meter thick. Maximum size, 0.45 by 0.49 millimeter; thickness, 0.21 millimeter.

Rare at F64 of the Quebradillas formation. E. nautiloideiim differs from E. poeyanum (d^Orbigny) in the more numerous chambers and less lobulate periphery; from E. australe Cushman and Parker (1931. Proc. U. S. Nat. Mus. 80 (3)) in having less depressed sutures and less papillate ornamentation; and from E. incertiim (Williamson) (1858. Recent Foram. Gt. Brit.) in having papillate umbilici, more chambers, nearly radial sutures and more retral processes.

Rare at A79 of the Los Puertos formation, and at F359 of the Quebradillas formation. Common at P259 of the Ponce formation. GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 365 This species differs from E. sagrai in being larger, and broader and flatter along the back; the apertural face is lunate in outline, not subtriangular ; the number of septal bridges along the sutures is greater, 18 instead of 7 or 8 as in sagrai; the ridges formed by the continuous septal bridges in the early part of the test are finer and not as conspicuously spiral as in E. sagrai. E. puertoricense differs from E. sagrai crassum in having a more lobulate outline, in being umbilicate instead of umbonate, and in hav- ing more septal bridges (15-18 instead of 10-12) which are not as clearly continuous from chamber to chamber and are not raised into ridges.

Test small for the genus, not compressed, subcircular in side view, subovate in edge view, widest portion of test in last chamber mid- way between umbilicus and periphery; periphery not lobate; edge rounded; umbilical regions somewhat depressed; chambers numerous, 10-12 in last adult whorl, last formed chambers slightly inflated; sutures not depressed except between last 2 or 3 chambers and marked by retral processes which are continuous over early part of test to form spiral ridges, oblique to the periphery; aperture a series of small round openings at base of the apertural face. Diameter, 0.27 by 0.36 millimeter; thickness, 0.20 millimeter. Plesiotype No. 4139, locality LlC, San Sebastian formation. Rare at L2C, L3C, and L5C; common at LlC and L6C of the San Sebastian formation. Rare at A86 of the Cibao formation. Com- mon at A79 of the Los Puertos formation. Rare at F64, A46, and A15; common at F358; abundant at F359 of the Quebradillas forma- tion. Common at P258 and P259 of the Ponce formation. This species was evidently named by d^Orbigny for his patron, De la Sagra, and the form of the specific name should therefore be sagrai instead of sagra or sagrum. There is considerable individual variation within this species. The larger individuals are thicker in proportion, have more septal bridges and a broader apertural face. All intermediate stages may be found. 366 SCIENTIFIC SURVEY OF PORTO RICO Elphidium sagrai crassum new variety Plate 15, figures la, b Test of medium size for the genus, little compressed; periphery not lobulate; edge broadly rounded, more rounded near the apertural end; chambers numerous, 11-12 in the last whorl; sutures not de- pressed, rather obscure, marked by longitudinal septal bridges which form continuous ridges with a somewhat spiral pattern on the earlier portions of the test; depressions between septal bridges are narrow and slit-like; 14 septal bridges between last 2 chambers on each side of test; apertural face lunate, twice as wide as high; aperture a row of round pores at base of last septal face. Diameter, 0.36 by 0.43 millimeters; thickness, 0.27 millimeter. Holotype No. 3910, locality LlC, San Sebastian formation. Rare at LlC, L2C, and L6C of the San Sebastian formation. Rare at A91a; common at A79 of the Los Puertos formation. Rare at r64 and r358; common at F359 of the Quebradillas formation. Rare at P258, P259, and 434 of the Ponce formation. E. sagrai crassum differs from E. chipolense (Cushman) (1921. U. S. Geol. Surv. Prof. Pap. 128B 72. pi. 11, fig. 23) in being smaller and thicker. It differs from E, sagrai (d'Orbigny) in that the sutural depressions of E. sagrai crassum are more elongate, and the aper- tural face is more lunate without the sharply rounded peripheral angle. It differs from E. puertoricense in that the spiral costae are stronger, and the test thickens more rapidly. It differs from E. rugosum (d'Orbigny) from the Vienna Basin Miocene in being thicker and in the resultant different shape of the apertural face. ANTILLESINA new genus Genotype, Nonion ? marielensis Palmer (1936) Mem. Soc. Cubana Hist. Nat. 10: 127. text flgs. 1-3. Lower Oligocene, Cuba. Test free, planispiral throughout, involute, non-umbilicate, becom- ing more embracing as more chambers are added; round on the back; chambers numerous, 4 to 7 in the last whorl, inflated; sutures de- pressed; wall calcareous, finely perforate; surface costate; aperture absent or represented by small pores on the septal face. Length, 0.24 to 0.50 millimeter. Shallow water marls. Eocene of Egypt, Oli- gocene of West Indies. Although we have about 40 specimens, many of them well preserved, not one shows a crescentic aperture and even the pores on the septal face are scarcely larger than the pores elsewhere on the test. GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 367 This species and the form figured by Schwager as Polystomella ? obscura from the Eocene of Egypt (1883. Paleontogr. 30 (2): 138. pi. 27, figs. 2a-c) are the only known members of this new genus. The significant characteristics of this genus, whereby it differs from Nonion, are its aperture, its completely involute test, and its costate ornamentation. The most closely related genus is Pullenia, rather than Nonion, Antillesina differs from Pullenia only in its porous aperture and costate ornamentation.

Longest diameter, 0.36 millimeter; thickness of last chamber, 0.24 millimeter. Holotype No. 4111, locality P4, Ponce formation. Rare at P4 of the Ponce formation. This species is most like ^^Discorbina'^ tuberculata Balkwill & Wright, but differs in the larger umbilicus, more highly spinose sur- face; the pores do not emerge at the ends of the spines, and the aper- ture is farther toward the periphery. VALVULINERIA Cushman 1926 Valvulineria maclureaformis new species Plate 16, figures la-c Test oval in side view, with nearly smooth periphery ; biconvex, the dorsal side nearly flat, ventral side very deep ; edge narrowly rounded to truncate in the last chambers; chambers not inflated, about 7 in the last whorl, enlarging rapidly radially and in thickness but not in length; less than 2 whorls; sutures on the dorsal side strongly and regularly curved, limbate and slightly raised, marked by broad bands of clear shell material; sutures on the ventral side slightly curved, slightly raised, marked by broad bands of clear shell material; ven- tral side with large, deep umbilicus; dorsal side with a slight amount of secondary wall material, thickest near the middle, slightly obscur- ing the spire; wall finely but distinctly perforate; aperture a slit opening into the umbilicus and extending less than half way towards the periphery, partly covered by a valvular lip. Diameter, 0.73 millimeter; thickness, 0.45 millimeter. Holotype No. 4113, locality A86, Cibao formation. Rare at A86 of the Cibao formation. This form somewhat resembles forms which have been included in Cibicides (1935. U. S. Geol. Surv. Prof. Pap. 181: pi. 23), but neither the aperture nor the mural pores are like those of Cibicides. The specific name was suggested because of the resemblance of this form to the gastropod genus Maclurites, 370 SCIENTIFIC SURVEY OF PORTO RICO Valvulineria nuttalli Palmer & Bermudez Plate 16, figures 2a-c ?

Length, 1.29 milli- meter; width, 0.73 millimeter; thickness, 0.49 millimeter. Plesiotype No. 4028, locality P3, Ponce formation. Rare at P3 of the Ponce formation. As stated by Palmer and Bermudez, V. nuttalli differs from F. inaequalis (d'Orbigny) (1839. Voy. Amer.

Test small for the genus, about equally biconvex; edge bluntly angled; slightly lobulate in dorsal view, usually 6 chambers in the last whorl, about 2^/^ whorls in the test; chambers of uniform shape, gradually increasing in size as added, slightly inflated ventrally; spiral suture on dorsal side marked by clear shell material; sutures on the dorsal side obliquely curved, flush with the surface, marked by clear shell material, on the ventral side nearly radial and some- what depressed; aperture obscure, apparently a narrow slit at the inner margin of the last formed chamber on the ventral side. Diam- eter, 0.28 by 0.32 millimeter; thickness, 0.13 millimeter. Plesiotype No. 3912, locality L2C, San Sebastian formation. Rare at L2C and L3C of the San Sebastian formation. Eponides omatissimus new species Plate 17, figures 2a-c Test delicate, planoconvex, dorsal side convex, ventral side flat with relatively large round or oval umbilical depression; edge angled; test nearly circular in side view, periphery not lobulate but with minute irregularities where the costae reach the periphery; as many as 3 whorls in the test, all visible from the dorsal side, only the last whorl from the ventral side, 12 to 15 chambers in the last whorl, enlarging very slowly; sutures radial but sharply curved near the periphery on both sides of the test; wall finely perforate; dorsal side of test conspicuously ornamented by raised spiral sutures and radial costae which are not continuous from whorl to whorl and which approximate the position of the sutures and usually bifurcate near the periphery with one branch following the curvature of the sutures; aperture a low slit at the base of the last chamber on the ventral side extending from midway of the base of the septal face nearly to the periphery; aperture obscure in most of the specimens. Diameter, 0.23 by 0.28 to 0.38 by 0.41 millimeter; thickness, 0.11 millimeter. Holotype No. 3913, locality L2C, San Sebastian formation. Common at L2C of the San Sebastian formation. Rare at A43a 374 SCIENTIFIC SURVEY OF PORTO RICO and A86 of the Cibao formation. Common at A79 of the Los Puertos formation. Rare at P2 of the Ponce formation. There are strong resemblances between E. ornatissimus and '^Plan- ulina^^ camagueyana Bermudez from the Eocene of Cuba (1927. Mem. Soc. Cubana Hist. Nat. 11). E, ornatissimus has fewer chambers, more regular ornamentation on the dorsal side, and is smaller in size.

Test biconvex, usually with dorsal side more convex than the ven- tral; edge angled, with narrow keel, nearly circular in dorsal or ventral view, periphery smooth, or very slightly lobate in the last few chambers; about 3% whorls in the test, early ones obscure on the dorsal side of the test, only those of the last whorl being dis- tinct; 6 to 7 chambers in the last whorl, enlarging slowly, closely appressed; sutures on the dorsal side flush with surface, oblique, nar- rowly limbate, on ventral side nearly radial, flush, or slightly de- pressed near the periphery, becoming limbate and raised near the umbilical region where they become fused into a ring surrounding a small but deep umbilical depression; aperture an elongate arch with lip at the base of the last chamber on the ventral side midway be- tween the umbilicus and periphery. Diameter varies from 0.36 by 0.41 to 0.84 by 0.93 millimeter; thickness, 0.30 to 0.54 millimeter. Holotype No. 3914, locality A21, Quebradillas formation. Rare at A93; common at A20; abundant at A21 of the Quebra- dillas formation. Rare at P3 of the Ponce formation. This species is related to E. antillarum (d'Orbigny) from the Recent of Cuba, but differs consistently in several respects. The sutures on the dorsal side are more oblique, the last whorl is narrower, and the periphery is not lobulate. Several other species from Eocene- Oligocene formations of the Gulf Coast and West Indian region are similar in some respects. Most of these lack the characteristic raised limbate ornamentation of the ventral side. Those that have similar ornamentation differ in having radial, not oblique dorsal sutures, as E, mexicana Cushman (1925. Am. Assoc. Petr. Geol. 9) and E. guayabalensis Cole (1927. Bull. Am. Paleont. 14), or in having more chambers as in E, byramensis cubensis Palmer and Bermudez (1936. Mem. Soc. Cubana Hist. Nat. 10). GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 375 Specimens at P3 which are referred to this species differ consistently in that they are much more flat on the dorsal side. This may be a variety of E. parantillarum or may merely show the extreme indi- vidual variation of the species. Eponides pulvinus new species Plate 18, figures 2a-c Test subcircular in side view, unequally biconvex, slightly convex on the ventral side, strongly convex to conical on the dorsal side; pe- riphery not lobulate ; edge sharply angled ; whorls about 4, on the ventral side involute leaving a very small umbilicus, the earlier whorls on the dorsal side covered by smooth secondary wall ma- terial, obscuring the spire; 5 chambers in the last whorl, increasing slowly in size; sutures on the ventral side nearly radial, very slightly curved, flush with the surface excepting between the last few cham- bers where they are depressed; sutures on the dorsal side somewhat limbate, slightly curved and tangential to the earlier whorls; surface of both sides smooth; aperture a slit at the base of the septal face extending and widening from near the umbilicus to two-thirds of the way to the periphery, with prominent upper lip. Diameter, 0.65 millimeter; thickness, 0.35 millimeter. Holotype No. 4103, locality A15, Quebradillas formation. Common at A86 of the Cibao formation. Rare at A15 of the Que- bradillas formation. This species differs consistently from E. advena (Cushman) (1923. U. S. Geol. Surv. Prof. Pap. 133) in being deeper on the dorsal side and shallower on the ventral side. It has fewer chambers and is higher dorsally than E. jacksonensis (Cushman and Applin) (1935. U. S. Geol. Surv. Prof. Pap. 181).

Diameter, 1.1 millimeters; thickness, 0.5 milli- meter. Plesiotype No. 4093, locality A21, Quebradillas formation. Rare at A21 of the Quebradillas formation. Our specimens lack the ventral limbate sutures usually ascribed to this species, and have an umbonal lobe not seen in Brady^s figure in the Challenger Report. They are much like the Florida Miocene specimens. Eponides ventricosus NEW species Plate 18, figures 3a-c Test subcircular in side view, strongly and almost equally convex, the dorsal side smoothly hemispherical, the ventral side slightly con- vex just beneath the periphery; periphery smooth, but sometimes slightly lobulate in the last few chambers; edge sharply angled to sharply rounded, sometimes appearing keeled, whorls about 3, nar- row, only the last one or part of the last one visible on the dorsal side, which is covered with a smooth, mottled secondary deposit; chambers 11 to 13 in the last whorl, enlarging gradually; ventral side with strong, smooth, imperforate umbo; dorsal sutures slightly curved, oblique, broadly limbate but not raised, the spiral suture also limbate but not raised; ventral sutures curved, narrowly limbate, flush with the surface, except for the last few which may be broadly depressed; ventral surface finely mottled; wall finely perforate, the perforations seeming to continue through the secondary deposit on both sides of the test; appearing on the dorsal umbo as coarse puncta, so that the form might be mistaken for Cibicides ; aperture a low arch midway between umbo and periphery, with slight upper lip. Diam- eter, 0.5 millimeter; thickness, 0.33 millimeter. Holotype No. 4116, locality A86, Cibao formation. Abundant at A86 of the Cibao formation. Rare at A21 of the Quebradillas formation, and at P251 and P259 of the Ponce formation. Eponides vortex new species Plate 18, figures 4a-c Test biconvex, somewhat compressed, central portion of dorsal and ventral sides inflated with last whorl thinner, forming a somewhat GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 377 explanate border; ventral side umbonate; early whorls on the dorsal side obscure, 10 chambers in the last whorl, short and wide, enlarging very gradually in size; periphery not lobate; edge sharp; sutures strongly and nearly equally curved on both sides of the test, nearly flush with the surface and marked by clear shell material, the last few on the ventral side raised; wall very jfinely perforate; aperture a low arch near the periphery on the inner margin of the last chamber on the ventral side, with lip. Diameter, 0.83 millimeter; thickness, 0.36 millimeter. Holotype No. 3915, locality A86, Cibao formation. Common at A86 of the Cibao formation. This species is quite distinctive, but has some points of resemblance to ^^Anomalina" subtenuissima Nuttall (1928. Quart. Jour. Geol. Soc. London 84). It differs in being thicker, without depressed sutures, and with a narrower final whorl on the dorsal side of the test.

Test small, subcircular in top view, dorsal side nearly flat, the last whorl flat or depressed, the earlier whorls slightly convex, ven- tral side unusually deep for the genus, with a moderately large um- bilicus; chambers about 6 in the last whorl; dorsal sutures slightly curved and moderately oblique, not depressed or raised, obscured by a slight deposit of secondary material; ventral sutures slightly curved, nearly radial, flush with the surface, narrow; entire surface smooth; aperture a long slit at the base of the septal face midway between umbilicus and periphery, with small upper lip. Diameter, 0.64 milli- meter; thickness, 0.5 millimeter. Plesiotype No. 4114, locality P3, Ponce formation. Rare at P3 of the Ponce formation. This form is unusually deep ventrally and has fewer chambers than most other species of the genus. There are fewer chambers in the last whorl, and the dorsal surface of the final whorl is more flattened than in d'Orbigny^s model of G. soldanii. 378 SCIENTIFIC SURVEY OF PORTO RICO Gyroidina stellifera new species Plate 15, figures 6a-c Test subcircular in side view, biconvex, thick dorso-ventrally, dorsal side moderately convex, ventral side very convex; periphery not lobulate; edge sharply angled; whorls about 3; chambers about 6 in the last whorl, enlarging gradually; sutures on the dorsal side curved and long, oblique, tangential to the earlier whorl, limbate but scarcely raised, the spiral suture limbate and raised; dorsal side covered with a smooth secondary deposit obscuring the sutures, thicker over the earlier whorls; ventral sutures slightly curved, scarcely depressed, nearly flush with the surface; ventral side smooth, with secondary deposit around the small umbilicus, raised, in the form of a star, with a lobe just posterior to each suture; aperture a small arch at the base of the septal face, midway between umbilicus and periph- ery, with slight upper lip.

Diameter, 0.5 millimeter; thickness, 0.24 milli- meter. Plesiotype No. 4106, locality P431, Ponce formation. Common at P431 of the Ponce formation. The Porto Rican specimens seem to differ somewhat from the original figures of R. hyramensis, particularly in the much smaller size (0.5 millimeter instead of 2 millimeters), fewer chambers, and less pointed chambers, but inasmuch as the Choctaw Bluff forms, which seem identical with the Porto Rican form, have been re- ferred to this species, we are for the present placing our material in this species. RotaUa choctawensis Cushman & McGlamery Plate 19, figures 2a-c Rotalia choctawensis Cushman & McGlamery (1938) U. S. Geol. Surv. Prof. Pap. 189D: 110. pi. 27, flg. 4. Middle Oligocene, Alabama. Test subcircular in side view, biconvex, the ventral side slightly deeper; periphery irregular; edge bluntly angled; ventral side with round, prominent umbo; 10 to 12 chambers in the last whorl, gradually enlarging, somewhat irregular in size; sutures on the dorsal side shghtly curved, raised, obscure; sutures on the ventral side nearly radial, depressed; surface on both sides, more on the dorsal side, covered with secondary wall material in irregular, lumpy masses; aperture a small slit at the base of the septal face, about midway be- tween umbo and periphery, with slight upper lip. Diameter, 0.56 millimeter; thickness, 0.31 millimeter. Plesiotype No. 4107, locality LlC, San Sebastian formation. Rare at LlC of the San Sebastian formation. This species is scarcely distinguishable from R. mexicana, differing mainly in the rougher surface. It is noteworthy that R. choctawensis does not occur in the Ponce formation, which has at least five other 380 SCIENTIFIC SURVEY OF PORTO RICO species of Rotalia, nor does any other species of Rotalia occur in the San Sebastian formation, so far as our collections show. Rotalia mexicana Nuttall Plate 19, figures 3a-c Botalia mexicana Nuttall (1928) Jour. Paleont. 2: 374. pi. 60, figs. 6-8. Upper Eocene. Mexico. Test subcircular in side view, biconvex, deeper on the ventral side; edge angled to sharply rounded; periphery even and papillate except for the last few chambers which are extended radially into blunt points, giving an angularly lobate outline to the test; whorls not involute on the dorsal side; 10 to 12 chambers in the last whorl, obscure on the dorsal side, distinct on the ventral side, not inflated; sutures slightly curved and flush dorsally, nearly radial and conspicuously depressed ventrally, meeting near the umbilicus to form a narrow, depressed ring around an umbonal boss of clear material; surface of the dorsal side smooth or granular; surface of the ventral side papillate near the pe- riphery and granulate with small, irregular depressions up to the central boss; aperture a narrow slit at the base of the septal face be- tween umbo and periphery, nearer the periphery, without definite lip. Diameter, 0.6 millimeter; thickness, 0.45 millimeter. Plesiotype No. 4109, locaUty P253, Ponce formation. Common at P4, P253, and P432 of the Ponce formation. Our specimens are uniformly deeper ventrally than dorsally. Nuttall states, "the dorsal side strongly convex and the ventral flattened''. He may have been using the words "dorsal" and "ven- tral" in the opposite sense from that of general usage, or have made an error. Otherwise, our form is very similar to NuttalFs.

Test large, biconvex, ventral side the deeper; subcircular in side view; periphery smooth but papillate in the early part of the last whorl becoming sUghtly lobate in the later part; edge subangular in young specimens to narrowly rounded in adult; 11 to 13 chambers in the last whorl, enlarging gradually; test involute to umbo on the ventral side, with a large round or oval central boss and several small GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 381 bosses of clear shell material; dorsal side with some of the later cham- bers distinct, the last half whorl usually raised above the earlier whorls, the earlier whorls and much of the last whorl covered with secondary- wall material in a rough and papillate manner; ventral side covered with secondary material, thickest near the periphery, making an in- tricate pattern of radial and concentric knobs; sutures on the ventral side distinct, radial, depressed particularly toward the umbo; sutures on the dorsal side slightly curved, obscure except for the last few chambers where they are depressed; aperture a short slit at the base of the septal face, nearer the periphery than the umbo, obscured by the secondary deposit, without definite lip. Diameter, 1.15 milli- meters; thickness, 0.58 miUimeter. The largest specimens are nearly 2 millimeters in diameter. Plesiotype No. 4075, locality P431, Ponce formation. Abundant at P431 of the Ponce formation. This variety differs from R, mexicana in the rougher surface, and from R, chodawensis (1938. U. S. Geol. Surv. Prof. Pap. 189D) in the regularity of the ventral ornamentation. Rotalia meyerhoffi new species Plate 20, figures la-c Test small, oval in side view, the later part of the last whorl being very broad radially; biconvex and biumbonate, the ventral side more strongly convex, involute more than half the width of a whorl on the dorsal side, tending to become evolute on the ventral side, exposing more than the last whorl to view; periphery not particularly lobulate but with a slight projection at the anterior periphery of the last few chambers where there is a short spine; edge angular in the last few chambers, somewhat rounded by papillate secondary wall tissue in most of the last whorl; whorls few; chambers 9 to 11 in the last whorl, increasing gradually in length, very broad radially, only those of the last whorl, or less, visible on the dorsal side due to secondary shell material which covers the earlier whorls and makes an umbo; ventrally the um- biHcal region is filled by a boss of clear shell material; surface smooth on the ventral side, granulate on the dorsal side and papillate on and near the periphery on both sides of the test; sutures on the ventral side nearly radial, narrow and depressed, on the dorsal side slightly curved, hmbate and more or less raised; aperture a narrow sUt at the base of the last septal face between the umbo and the periphery, nearer the periphery, with small upper lip. Diameter, 0.7 miUimeter; thickness, 0.32 millimeter. 382 SCIENTIFIC SURVEY OF PORTO RICO Holotype No. 4108, locality P431, Ponce formation. Common at P431 of the Ponce formation. This species differs from all associated species of Rotalia^ and from nearly all other species of the genus, in being partially involute on the dorsal side, yet with very wide chambers radially. It most nearly resembles R. aculeata (d^Orbigny) (1846. Foram. Foss. Vienne pi. 8). We take pleasure in naming this species for Dr. Howard A. Meyer- hoff, Professor of Geology at Smith College, who has devoted many years to the study of the geology of Porto Rico, and who collected the foraminiferal material for the present study. Rotalia tholus new species Plate 20, figures 2a-c Test subcircular in side view, dome shaped in edge view, slightly convex ventrally, strongly convex, domal or even campanulate dorsally; edge angled but not keeled; periphery sHghtly lobulate, a little irregular but not erose; chambers 9 to 10 in the last whorl, increasing gradually in size, not inflated; whorls not involute on the dorsal side, the earlier ones obscured by strongly papillate or knobbed secondary shell material, most marked on the sutures; ventral side with a strong umbilical plug of clear shell material, separated by a groove from the chambers; sutures on the dorsal side gently curved, limbate and flush with the surface or raised, only those of the last whorl distinct; sutures on the ventral side slightly depressed, more so at the inner ends, not limbate, nearly straight, radial; surface of the ventral side unornamented except for a crescentic addition of second- ary material on the inner ends of the chambers; aperture a slit at the base of the septal face, midway between umbo and periphery, without upper lip. Diameter, 0.55 millimeter; thickness, 0.33 millimeter. Holotype No. 4110, locaUty P431, Ponce formation. Common at P431 of the Ponce formation. This species differs from R. alabamensis Cushman and McGlamery (1938, U. S. Geol. Surv. Prof. Pap. 189D) in the flatter ventral side, more domed dorsal side, more chambers, and smoother, non-keeled edge. The specific name refers to the cupola or dome-shaped dorsal side of the test, from the Latin noun, tholus.

Average diameter, 0.31 by 0.36 millimeter; thickness, 0.16 millimeter. Holotype No. 3898, locality L5C, San Sebastian formation. Common at L5C; rare at L3C of the San Sebastian formation. This species seems related to the D. mirus-orhicularis group. It differs from D. mirus Cushman (1922. Carnegie Inst. Wash. Publ. 311) in having a smooth, not lobulate outline; nonlimbate, more oblique dorsal sutures; fewer chambers, and a smaller test. It differs from D. orbicularis (Terquem) (1876. Ess. Anim.

Diameter, 0.69 millimeter; thickness, 0.30 milUmeter. Holotype No. 4141, locality A21, Quebradillas formation. Common at locality A21 of the Quebradillas formation. This species is obviously similar to several forms as yet included in D. orbicularis (Terquem), particularly the Florida Miocene form (1932. Fla. Geol. Surv.

Test rotaloid, convex on the dorsal side, with depressed spire, concave on the ventral side, broadly oval in side view; periphery lobulate; back smoothly rounded; chambers 7 to 8 in the last whorl, inflated, increasing rapidly in size as added; whorls about 2; early whorls on the dorsal side separated from the last whorl by a depressed spiral suture; on the ventral side secondary shell material forms GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 387 triangular places over part of each chamber converging at the um- bilicus; dorsal sutures nearly radial, distinct, depressed, marked by clear shell material; ventral sutures depressed, radial, narrow between the secondary deposits; between the chambers on the back of the test there are one or two retral processes or septal bridges similar to those in Elphidium; wall coarsely and plainly perforate, the perfora- tions continuing through the ventral secondary deposits; aperture a wide slit at the base of the septal face, usually closed by secondary material, and elongate secondary apertures between the chambers on both sides near the periphery, the accessory apertures being outlined by thin bands of clear shell material ; there are no accessory apertures at the outer edges of the triangular umbilical plates. Diameter, 0.87 by 0.62 millimeter; thickness, 0.33 millimeter, for the medium-sized figured specimen. Holotype No. 4115, locality P258, Ponce formation. Common at P258 of the Ponce formation. This species differs from the Recent Arctic species, E. rimosa (Parker and Jones) (1865. Phil. Trans. Roy. Soc. London 155) in having septal bridges and lacking the openings at the outer ends of the triangular umbilical plates. The septal bridges are similar to those in D. polystomelloides (Parker and Jones), but are fewer, there are fewer chambers, and the deposits are thinner and smoother. Our form seems to be identical with the form identified with Dis- corbina polystomelloides by Heron-Allen and Earland, from the Kerimba Archipelago, in an extraordinary provincial fauna.

Diameter, 0.73 millimeter; thickness, 0.37 millimeter. Plesiotype No. 4041, locality P254, Ponce formation. Rare at P251 and P254 of the Ponce formation, and at A93 of the Quebradillas formation. We include this form in Anomalina because of the nearly planispiral coiling and because the spire on neither side is completely covered by the last whorl. Other forms similar or identical with this species are Anomalina umhonata Cushman (in Howe 1939. La. Dept. Cons. Geol. Bull. 14) and Anomalina nolani Hedberg (1937. Jour. Paleont. 11). GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 389 There is considerable variation in the amount of sutural limbation and thickness of the umbos in this species (or these species), depending more on the ontogenetic age of the specimens than on the geologic age.

Diameter, 0.32 by 0.39 millimeter; thickness, 0.23 millimeter. Holotype No. 3867, locality A86, Cibao formation. Rare at A86 of the Cibao formation. This species differs from A. grosserugosa (Gtimbel) (1870. Abh. k. bay. Akad. Wiss. Miinchen Math. Phys. CI. 10) in its greater thick- ness and fewer chambers. As Thalmann pointed out in 1932, Brady's specimens in the Challen- ger Report are not true A. grosserugosa (Gtimbel), but neither are they the same as this Porto Rican species. Brady's form has more cham- bers in the last whorl, i, e. eight.

This species is not well defined and not definitely recognizable, since several different forms have been included in it by its author. It is scarcely distinguishable from C floridanus. As we distinguish the species, C. pseudoungerianus has little limbation and thin secondary deposits; C. floridanus has strong limbation on both sides, thick 396 SCIENTIFIC SURVEY OF PORTO RICO secondary deposit on the dorsal side in which the mural pores are enlarged. The difference in number of chambers and relative convexity is not significant. Cibicides scalenus new species Plate 23, figures 3a-c Test very small, oval in side view, dorsal side flat or slightly convex, ventral side very convex, with small umbilicus; whorls about 2; cham- bers about 8 in the last whorl, increasing gradually up to the last few chambers when the chambers increase very rapidly in all dimensions; edge sharp, but not keeled; periphery smooth up to the last few chambers when it becomes lobulate, bordered by clear shell material; sutures on the dorsal side gently curved, limbate but not raised, the spiral suture being both limbate and raised; ventral sutures strongly curved, the outer ends limbate but not raised; wall conspicuously perforate; aperture a small arch on the inner periphery at the base of the last septal face, with upper lip, extending on the dorsal side for a distance of about two chambers. Diameter, 0.32 millimeter; thickness, 0.16 millimeter. Plesiotype No. 4121, locality A43a, Cibao formation. Rare at 43a of the Cibao formation. The Porto Rican form resembles C. westi Howe (1939. La. Dept. Cons. Bull. 14), but C. scalenus is less conical on the ventral side, and the ventral sutures are not strongly sigmoid.

Test subcircular in side view, nearly equally biconvex, coiled sinistrally; periphery not lobulate; edge subangular; whorls 33^, gradually enlarging, not overlapping the earlier whorls on the dorsal side; chambers 10 to 11, gradually enlarging; dorsal side covered by a thin, transparent secondary deposit; ventral side with strong umbo of clear shell material; dorsal sutures curved, slightly limbate but not raised; ventral sutures slightly curved, the later one sometimes sig- moid, narrowly limbate but flush with the surface; wall coarsely but not conspicuously perforate; aperture a small arch at the base of the septal face on the inner periphery, with upper Up, extending a very short distance ventrally and extending dorsally for a distance of 2 or 3 chambers. Diameter, 0.43 millimeter; thickness, 0.23 millimeter. GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 397 Plesiotype No. 4101, locality A86, Cibao formation. Rare at A86 of the Cibao formation. This species differs from C floridanus and C. pseudoungerianus in having a narrower last whorl which does not overlap earlier whorls on the dorsal side. It differs from C. perlucida in the fewer whorls and less conspicuous pores. It differs from C. pseudoungerianus evoluius (1935. Contr. Cushman Lab. Foram. Res. 11: 64. pi. 9, fig. 11) only in coiling to the left. The sinistral coiling seems to be of little signifi- cance, in view of the fact that many species of Foraminifera coil normally both sinistrally and dextrally. It must be admitted, how- ever, that there are races, varieties or even species, which coil in only one direction for a given locality and geologic age. Cibicides spirolimbatus new species Plate 25, figures la-c Test of medium size for the genus, subcircular in side view, biconvex and biumbonate, the ventral side slightly deeper; periphery not lobu- late; edge sharply rounded, not keeled; whorls about 4, unusually narrow for the genus, not increasing much in width as growth proceeds, not overlapping on the dorsal side; about 12 chambers in the last whorl, gradually increasing in size as added; dorsal sutures slightly curved, moderately oblique, more and more limbate toward the center of the test, but not much raised, the spiral suture limbate and raised with clear shell material; the growth of the secondary material on the sutures obscures the spire especially toward the center but leaving the mural perforations in the reduced rhomboidal areas corresponding to the chambers; sutures on the ventral side sUghtly curved, narrowly limbate and flush with the surface, merging into the umbo of clear shell material; aperture a low arch just below the periphery with upper lip, extending on the dorsal side between the whorls for a dis- tance of one or two chambers. Diameter, 0.87 millimeter; thickness, 0.40 millimeter. Holotype No. 4122, locality A93, Quebradillas formation. Rare at A93 of the Quebradillas formation. This species differs from C. mundula (Brady, Parker and Jones) (1890. Trans. Zool. Soc. London 12) in being ventrally umbonate, in the curved sutures and the aperture not on the inner periphery. The narrow whorls and spiral limbation are characteristic. 398 SCIENTIFIC SURVEY OF PORTO RICO PLANULINA d'Orbigny 1826 Planulina crassa new species Plate 25, figures 2a-c Test nearly circular in side view, compressed in edge view yet rather thick, dorsal side flat or slightly concave, ventral side flat or slightly convex; back flat or slightly concave, a little oblique to the two sides; whorls 2 to 3, scarcely at all involute on the ventral side, slightly involute on the dorsal side; chambers 9 to 10 in the last whorl, increasing gradually in size as added; sutures on the dorsal side much curved and strongly raised, merging with the raised border; ventral sutures strongly curved and raised; wall coarsely perforate, the ventral surface strongly granulate between the sutures and on the sutures, and finely granulate on the dorsal surface over the early whorls; aperture at the base of the septal face on the inner periphery, with upper lip, not extending onto the ventral side but extending onto the dorsal side between the last two whorls for a distance of one or two chambers. Diameter, 0.45 millimeter; thickness, 0.13 millimeter. Holotype No. 4065, locality A21, Quebradillas formation. Abundant at A21; rare at A15; common at A20 and A93 of the Quebradillas formation. This species differs from P. ariminensis d'Orbigny in that it is much thicker and the chambers are narrower in proportion to their length.

Test large, subcircular in side view, much compressed, concavo- convex to plano-convex, ventral side moderately convex but without an umbilical boss of secondary shell material; edge sharply angular; periphery lobulate, more strongly so in the last half whorl, with narrow, limbate border; some of the earlier whorls show on both sides of the test, the early dorsal spire covered with a thin, granular, secondary deposit; chambers short and wide, a little inflated on the ventral side, enlarging more rapidly in width than in length or thickness, about 9 in the last whorl; ventral sutures most distinct between the chambers of the last half whorl where they are conspicuously depressed, nearly radial near the center of the test, sharply curved near the periphery; dorsal sutures strongly curved, flush with the surface or slightly de- GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 399 pressed, slightly limbate on the outer end where the limbation merges into the border; wall moderately coarsely perforate; aperture a small, high arch, with strong upper lip, at the base of the septal face on the inner periphery, extending onto the dorsal side for a distance of 3 or 4 chambers. Diameter, 1.38 millimeters; thickness, 0.26 millimeter. Plesiotype No. 4124, locality P255, Ponce formation. Rare at P255 of the Ponce formation.

Test large, nearly circular, biconvex, much compressed; periphery smooth, except for the last few chambers; edge angled, with narrow peripheral keel of clear shell material, more distinct on the earlier chambers of the last whorl; dorsal side of test showing 2)^ to 3 rapidly widening whorls, ventral side involute nearly to umbiUcus; chambers short and wide, 10 to 12 in the final whorl of the adult; dorsal sutures broadly curved, limbate, usually raised with the raised limbation more conspicuous on the early whorls; ventral sutures broadly curved, the later ones sigmoid, limbate, usually raised; the largest specimens umbilicate; wall coarsely perforate; aperture at the base of the last chamber on the inner periphery, extending a short distance onto the dorsal side between the last two whorls. Diameter, 1.52 millimeter; thickness, 0.25 millimeter. Plesiotype No. 4125, locality P2, Ponce formation. Rare at P251; common at P3 and P255; abundant at P2 and P254 of the Ponce formation. It is quite possible that the forms figured by Hadley (umbonate, 9 chambers) and that figured by Palmer and Bermudez (umbilicate, 12 to 14 chambers) represent two different species, both of which are represented in the Porto Rican material.

Prof. Pap. 181: 52. pi. 22, fig. 8. Upper Eocene, South Carolina. Test large, much compressed, complanate, sides flattened; edge narrowly rounded, not keeled; periphery slightly lobulate; early whorls visible on both sides of the test, becoming less involute with age, the final half whorl just touching the preceding whorl; chambers short and evenly curved, 7 to 8 in the last whorl; sutures distinct, sharply curved, limbate, flush with the surface or very slightly raised except between the last few chambers where they are depressed; wall coarsely perfo- rate; aperture a low arch with slight lip at the base of the last chamber extending on the dorsal side about half a chamber length. Diameter, 0.82 by 1.04 millimeter; thickness, 0.11 millimeter. Plesiotype No. 4066, locality P254, Ponce formation. Rare at P254 of the Ponce formation. This is one of the least involute species of the genus, the complete spire being visible on both sides of the test. Planulina zigzag new species Plate 26, figures 4a-c Test oval in side view, much compressed, nearly planispiral, the dorsal side flat, or with slight spiral depression inside the last whorl, rarely slightly convex, as in the specimen figured; ventral side slightly convex, with large, shallow umbilical depression; edge truncate or slightly concave, with sharp, continuous keel of clear shell material extending from the dorsal side, the ventral side with discontinuous keel formed by the outer edges of the sutural limbation; periphery smooth, formed by the dorsal keel; dorsal sutures nearly straight, radial, limbate and raised, the limbation continuing in a zigzag line from chamber to chamber, just inside the carina, the spiral suture limbate but not raised, sometimes depressed; whorls about 2, only slightly involute on each side; eight chambers in the last whorl, en- larging rapidly, not inflated; ventral sutures limbate and strongly raised, straight, radial, the raised limbation continuing in a con- spicuous zigzag line around the outer edge of the chambers, somewhat inside the dorsal carina, not joining to form a continuous carina; the radial and zigzag ridges on both sides of the test have fine, longitudinal striae on them; wall very coarsely and conspicuously perforate where the preservation is good; surface smooth, except for the raised ridges; septal face finely granulate; aperture a short slit at the base of the septal face, not continuing onto either dorsal or ventral side, with GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 401 slight upper lip. Diameter, 0.53 by 0.72 millimeter; thickness, 0.11 millimeter. Holotype No. 4126, locality A86, Cibao formation. Common at A86 of the Cibao formation. It is probably that P. zigzag is related to P. alavensis Palmer (1938. Mem. Soc. Cubana Hist. Nat. 12: 345, 346, text fig.), but P. zigzag differs in the zigzag line of the peripheral limbation and the absence of peripheral secondary apertures.

Family ACERVULINIDAE Schultze 1854 RUPERTIA Wallich 1877 Rupertia verrucosa new species Plate 27, figures 9a-c Test large, attached in life by the concave dorsal side, irregularly tuberose, not columnar; early chambers close coiled like Cibicides for one whorl or more, followed by irregularly arranged chambers forming a tuberose mass of round or elongate, loosely or closely appressed chambers; wall calcareous, thick, coarsely perforate; sur- face in the young smooth, showing the closely spaced, large pores; in the adult the surface is usually covered with a rough, nodular deposit of secondary calcareous, shell material; aperture a slit or large irregular arch at the base of the last septal face, with upper lip, never on the upper side of the test, nor tubular. Diameter, up to 4 millimeters; height, up to 3 millimeters. Diameter of figured speci- men, 3.1 millimeters; height, 3 millimeters. 404 SCIENTIFIC SURVEY OF PORTO RICO Holotype No. 4130, locality P4, Ponce formation. Abundant at P4 of the Ponce formation. This species differs from R, stabilis Wallich in the tuberose rather than columnar and bulbous shape, in the rough coating of secondary shell material in the adult test, in the lateral rather than terminal position of the aperture, and in the larger size. CARPENTERIA Gray 1858 Carpenteria bulloides new species Plate 27, figures 1 to 4 Test multilocular, irregularly cylindrical or columnar in the adult, globigerinoid in the young; chambers subglobular, increasing gradually in size from the apical, attached end, and arranged in an alternating series, 6 chambers in the adult test; sutures distinct, depressed; test attached in life, the place of attachment being on the first 2 or 3 chambers as shown by the cicatrix; aperture with a short neck of clear, imperforate shell material located on the side of the test opposite the point of attachment, in the adult terminal, not opening into the sutures or into an umbilical depression; aperture in the young oval in shape with a short flaring neck, in the adult round with a short conical neck; surface with large pores which are emphasized by deposits of secondary shell material, pores missing and the surface of the test smooth around the neck. Length of adult specimen, 1.61 millimeters; diameter, 1.21 millimeters. Holotypes No. 3881a, b, c, d, locality A21, Quebradillas formation. Common at A21 of the Quebradillas formation. C. bulloides lacks the broad basal attachment of C. lithothamnica Uhhg from the middle Eocene of West Galicia (1886. Jahrb. Geol. Reichsanstalt 36: 189. pi. 5, figs. 1, 2). It resembles even more closely C. alternata Chapman and Crespin from the middle Tertiary of Vic- toria (1930. Proc. Roy. Soc. Victoria 43 (1): 99. pi. 5, figs. 9, 10) but differs in the coarsely perforate character of its surface and in the position and character of its aperture. We are not satisfied with the generic disposition of this species, but do not wish to redefine the genus at this time.

Length of incomplete specimen, 2.0 millimeters; diameter, 1.0 millimeter. Plesiotype No. 4131, locality A21, Quebradillas formation. Common at A21 ; rare at A46 of the Quebradillas formation. Com- mon at P431 and P432 of the Ponce formation. Our specimens are not as elongate as specimens usually considered typical of this species, and the wall is more coarsely cellular or reticu- late. Perhaps they belong with C. utricularis. The species of Car- penteria vary so widely that it is difficult to identify any of them.

In cross section the microspheric nucleoconch is rotaloid, with later chambers added concentrically and arranged in radial lines; the radial tiers of chambers are conspicuous in natural cross sections of broken specimens as well as in laboratory sections; the later chambers are very numerous, in many concentric layers; chambers oval in shape, elongate parallel to the periphery with the length about twice the height, averaging 0.14 milhmeter in diameter, height 0.067 millimeter. Plesiotype No. 3990, locality P258, Ponce formation. Common at A21, F359, and A64 of the Quebradillas formation. Abundant at P258 of the Ponce formation. S. pilaris occurs also in abundance in the calcareous strata 8.5 kilometers west of Isabel II on the north shore of the Island of Vieques, just east of Porto Rico. Meyerhoff correlates these beds with the upper part of the Ponce formation. S. pilaris differs from S. globulus in being generally larger in size, with much coarser areolation on the surface; in cross section the chambers are much more numerous, more closely appressed radially, and elongate rather than nearly equidimensional in shape.

Test small for the genus, subglobular to broadly ovate, young specimens showing early globigerinoid chambers, adult forms with 3 chambers making up the entire visible portion of the test; sutures in the young test flush or very slightly depressed, the final suture of the adult fissure-like on the ventral side of the test, with jagged edges; wall thick with conspicuous, large pores which in some specimens make the surface rough; aperture a small round opening at the bottom of the fissure-like suture. Length, 0.59 millimeter; diameter, 0.43 by 0.46 millimeter. Plesiotype No. 3992, locality A21, Quebradillas formation. Abundant at A21 of the Quebradillas formation. This species is distinctive in its slight development of a sutural fissure, and the complete absence of a sutural fissure on the dorsal side of the test. No specimens of the form commonly referred to S. dehiscens (1865. Phil. Trans. 155) were found, hence it is improb- able that these are young or immature specimens of that species.

Test very small, probably immature, flabellate, compressed; chambers broadening very rapidly, tending to become annular, most of them arranged in an indefinite biserial manner, the later ones having radial depressions on the inner side (as if it were crimping due to bending of a tube, a feature seen in many bent, tubular forms) ; sutures slightly depressed, not limbate; wall finely and evenly perforate; sur- face smooth but minutely granular; apertures absent excepting for the small mural pores on the septal face. Length, 0.24 millimeter; breadth, 0.22 millimeter; thickness, 0.05 millimeter. 416 SCIENTIFIC SURVEY OF PORTO RICO Plesiotype No. 4136, locality A6, Lares formation. Rare at A6 of the Lares formation. We have only a single specimen of this rare genus and species. It has the fine pores of P. advena, differing from most other species of the genus, and lacks the limbate sutures and lateral carina of other species. Our specimen is in shape very similar to the early stages of P. flahelli- formisj as figured by Heron-Allen and Earland (1915. Trans. Zool. Soc. London 20: pi. 48, fig. 4). This form bears some resemblance to the early stages of Cyloloculina, but the chambers are not arranged in a uniformly spiral manner, and moreover this form does not occur with the numerous specimens we have from the Ponce and San Sebas- tian formations.

Length, 0.38 millimeter; width, 0.26 milli- meter; thickness, 0.15 millimeter. Holotypes No. 3874a, b, locality P2, Ponce formation. Common at P2 of the Ponce formation. We take pleasure in naming this species for Professor Aida A. Heine who was one of the first paleontologists to take an interest in the foraminifera of Porto Rico. This species resembles B. byramensis Cushman, but is a smaller, thicker, more oval form, not compressed, with reticulation that tends to be more longitudinal. Although B. heineae resembles B. reticulata Hantken (1875. Mitt. Jahrb. d. k. ung. geol. Anstalt 4) in general shape and size and fineness of reticulation, it differs in being thicker and having more definitely longitudinal costae which almost com- pletely obscure the sutures. 418 SCIENTIFIC SURVEY OF PORTO RICO Acid treatment was used to remove the surface ornamentation of one specimen and show the number of chambers and typical bolivine structure of this species.

Bolivina ventricosa new species Plate 31, figures 6a-c Test small with slight tendency to twist near the apical end, thickest in the middle of the test about midway of the length, tapering not only to the edges but also toward the apical and apertural ends ; test widen- ing more rapidly after the i&rst 3 or 4 pairs of chambers, apical end narrowly rounded, apertural end broadly rounded; edge angled, keeled; chambers closely appressed, about 9 pairs in the test, increas- ing markedly in width after the first 4 pairs, increasing very gradually in chamber length (i, e. adorally), greatest thickness at inner end of each chamber, the chamber thickness increasing rapidly for the first third of the test, decreasing equally rapidly for the last third of the test with maximum thickness of chambers about midway between apical and apertural ends; sutures conspicuously curved, flush with the surface, continuous with the narrow keel of clear shell material that borders the test; aperture narrow, parallel to the compression of the test extending up onto the last septal face from the base of the last chamber on the periphery. Length, 0.35 millimeter; width, 0.30 milhmeter; thickness, 0.17 milHmeter. Holotype No. 3879, locality P254, Ponce formation. Rare at P254 of the Ponce formation. This species is quite different from all other species of Bolivina, particularly in its unusual thickness and the rapid widening of its test in side view. The shape of B. ventricosa suggests Ehrenbergina, but the planispirally coiled early portion is lacking and the aperture is straight, narrowly elliptical and nearly terminal, rather than lateral, in position.

This species is close to the Recent species L. rostrum Cushman (1933. Contr. Cushman Lab. Foram. Res. 9: 82. pi. 8, fig. 13) from the tropi- cal Pacific, but differs in that L. normalis is smaller, is more tapering at the apical end, and has oblique sutures that become less oblique as chambers are added, rather than more oblique.

Test elongate, compressed, oval in front view, initial end narrow, bluntly pointed; proloculum subspherical followed by several biserially arranged chambers, the major portion of the test consisting of about 5, very slightly inflated, equitant, chambers; sutures marked with clear shell material, sUghtly depressed; aperture terminal, fissurine, not radiate. Length, 1.13 millimeters; width, 0.35 millimeter; thickness, 0.07 miUimeter. Plesiotype No. 3949, locality P2, Ponce formation. Very rare at P2, P3, and P254 of the Ponce formation. The original description of this species states that, 'Hhis species is peculiar in the retention of the alternating character of the chambers as shown by the apertures pointing first to one side and then the other in succeeding chambers and the incurved portion of the wall even after the alar projections are developed^', but it is evident from sub- sequent figures published by the originator of P. vaughani that this alternating character of the chambers throughout most of the test is not an essential differentiating characteristic. P. vaughani is essen- tially an elongate, oval form of moderate width with relatively few chambers, usually 5 to 7 equitant chambers following a short biserial portion of a few chambers. P. advena (Cushman) (1923. Bull. U. S. Nat. Mus. 104 (4)) is very similar, but is narrower and tends to be more irregular, or phylogerontic.

Plesiotype No. 3880, locality P254, Ponce formation. 424 SCIENTIFIC SURVEY OF PORTO RICO Rare at P254 and P255; common at P3; abundant at P2 of the Ponce formation. Since 1846, when B. ovata was first named by d'Orbigny, workers on foraminifera have consistently used this name for all smooth speci- mens of Bulimina with generally oval shape in side view, circular cross section, sHghtly depressed sutures and relatively few chambers. Several authors, among them Cushman in 1922, Nuttall in 1932, and Palmer and Bermudez in 1936, have noted that two types of smooth Buliminas have been included in B, ovata^ namely that of the original figure, and another which differs, ''from the original figure of the species in being broader in proportion to the length, with the final whorl of chambers covering about three-fourths of the length of the test'\ (Palmer & Bermudez p. 287.) A comparison of the Porto Rican speci- mens with the original figure of B. socialis Bornemann and the figures of B. socialis pubUshed by Cushman in 1937 shows that the non-typical forms of B, ovata which have been erroneously included under B. ovata should be called B. socialis^ a name which was proposed by Bornemann in 1855. It is improbable that the thicker type of Bulimina which we here call B. socialisy is the megaspheric form of B. ovata since only the B. socialis type occurs in the Porto Rican material, and not both types as would be expected if the two are the megaspheric and microspheric forms of the same species. B. socialis differs from B, ovata in the following respects: 1. the apical and apertural ends are narrowly to broadly rounded in shape, not sharply rounded or angular 2. the test is stouter; the form ratio (length divided by breadth) being 1.4 to 1.90, while B. ovata ranges from 2 to 2.4. The type figure of B. socialis was 1.57, of B. ovata 2.20.

Diameter, 0.53 by 0.60 millimeter; thickness, 0.30 millimeter. Holotype No. 4143, locality P255, Ponce formation. Rare at P2 and P3; common at P254 and P255 of the Ponce forma- tion. This species differs from C. delicata Cushman (1927. Scripps Inst. 426 SCIENTIFIC SURVEY OF PORTO RICO Oceanog. tech. ser. 1 : 168. pi. 6, fig. 5) in the fewer chambers and much shorter aperture. It differs from C, rarilocula Cushman (1933. Contr. Cushman Lab. Foram. Res. 9: 93. pi. 10, fig. 4), from the tropical Pacific, in the less inflated chambers, sharper edge, longer aperture, and larger size. Perhaps C. ^^delicatula" Cushman (obviously an error for ^'delicata^^) (1929. Contr. Cushman Lab. Foram. Res. 5: 101. pi. 14, fig. 12, Tertiary, Venezuela) is the same as our species, but the chambers are rather too inflated and the sutures too much curved.

Middle Miocene, Haiti. Test short subtriangular in side view, oval in edge view, pyramidal in apertural view; dorsal side convex, ventral side more strongly convex, with a broad, flat ridge down the center, bounded by concave slopes; edge sharp, with a short, fiat spine at the end and upper side of each chamber and a few, small spines on the apical, ventral end; chambers closely appressed, not inflated, about 7 pairs; dorsal sutures curved, overlapping about half their length, limbate, mostly flush with the surface, the middle part of the later ones raised; ventral sutures obscure, nearly flush with the surface, curved and overlapping on the ventral ridge; wall very finely perforate; surface smooth except for the raised sutures and spines on the edge and apical end; aperture a thin, curved slit just under the terminal part of the periphery, nearer the sutural side of the chamber, with thin lower lip. Length, 0.61 miUimeter; width, 0.56 millimeter; thickness, 0.30 milHmeter. Holotype No. 4140, locality P2, Ponce formation. Rare at P2 of the Ponce formation. This species is similar to E. bradyi Cushman (1927. Proc. U. S. Nat. Mus. 70 (16) : 5. pi. 2, fig. 1.) from deep water of the Pacific, but it lacks the median ventral groove and spines, the fine peripheral spines, and it is shorter. The subtropical middle Tertiary forms from Haiti and Porto Rico seem to be identical, and are readily distinguishable from the cold water Recent forms from the Pacific. E. navalis Hadley (1934. Bull. Am. Paleont. 20 (70A)) seems very close to E. caribbeaj but it is more slender, has more delicate spines, and lacks the small spines on the apical, ventral end of the test. GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 427 Ehrenbergina serrata gibbera new variety Plate 32, figures 5a-d Test subtriangular in dorsal view, oval in edge view, the early part as thick as the later part ; biconvex, oval in cross section with the back humped (hence the name gibhera), the later part uncoiled and perhaps also the earlier part, the exact nature of which is not determinable because of the addition of spines and other secondary material; edge sharply rounded in the earlier part, angled and slightly carinate in the later part; earlier part with a round spine extending out from the edge of each chamber and other spines on the apical end and on the early, ventral side; chambers 6 to 7 pairs, on the dorsal side short and wide, overlapping each other by about half their width; sutures on the back of the test limbate but flush with the surface, curved in three parts, usually orad, sometimes apicad; ventral sutures depressed, obscured by secondary material; surface smooth except for the spines; aperture elongate, narrow and curved, near the middle of the test, nearly parallel to the margin, with fimbriate lower lip and welt-like upper lip. Length, 0.60 milUmeter; width, 0.55 millimeter; thickness, 0.30 miUimeter. Holotype No. 3902, locahty P2, Ponce formation. Rare at P2 of the Ponce formation. This species differs from E. serrata Reuss (1850. Denkschr. k. Akad. Wiss.

Variation in length from 0.32 to 0.54 millimeter; diameter from 0.18 to 0.24 miUimeter; form ratio from 1.8 to 2.7 millimeters, averaging 2.2 millimeters. Holotype No. 4144, paratype No. 4144a, locality A86, Cibao forma- tion. Common at A86 of the Cibao formation. This form is like U. posticGf with which it occurs, but differs consist- ently in the following ways : it is smaller, the greatest width is nearer the apical end, the tapering to the aperture is more marked, the spines are smaller on the apical end and absent on the apertural end, and the costae are smaller. We have considered the possibility that one form is megaspheric and the other microspheric, but find no proof. Note the greater magnification of U, bulbacea.

It seems close to U. elongata^ but is shorter, more regular in shape, and has the spines in lines on the early part of the test.

U. gardnerae belongs to the U. pere- grina group, but differs in being thicker and shorter, with fewer costae, and absence of a granular surface. It is much like U. gardnerae cubana Hadley (1934. Bull. Am. Paleont. 20 (70A)) which lacks spines on the last chamber. It is also much like U. capayana Hedberg (1937. Jour. Paleont. 11 : 677. pi. 91), but is much larger and has much coarser costae. The various groups of species of Uvigerina have been insufficiently differentiated for definite recognition.

Uvigerina mantaensis Cushman & Edwards (1938) Contr. Cushman Lab. Foram. Res. 14: 84. pi. 14, fig. 8. Oligocene, Ecuador. Test stout, about 13^ times as long as wide, broadly fusiform in shape; chambers rather few, inflated; sutures distinct, depressed; wall hispid throughout; shoulders broad; aperture terminal, with a short, cylindrical neck and phialine lip. Length, 0.59 millimeter; diameter, 0.32 millimeter. Plesiotype No. 4076, locality P3, Ponce formation. Rare at P3 and P254 of the Ponce formation. [7. mantaensis differs from U. proboscidea Schwager (1866. Novara- Exped. Geol. Theil 2) in that it has a less tapering test and broad, not sloping, shoulders. Uvigerina mexicana Nuttall Plate 33, figure 9 Uvigerina mexicana Nutiall (1932) Jour. Paleont. 6: 22, pi. 5, figs. 12, 13. Lower Oligocene, Mexico. Test short, stout fusiform in shape; apical end subacute or pointed; thickest part of the test near or below the middle; lower % of the test ornamented by numerous low, round, longitudinal costae, which are continuous from chamber to chamber, and increase by division, less frequently by implantation; last chamber unornamented ; early chambers rather obscure, little inflated, last chamber slightly inflated; sutures flush with the surface, obscure in the early part of the test, last few marked by clear shell material; aperture round, at the end of GALLOWAY AND IIEMINWAY, TERTIARY FORAMINIFERA 431 a short cylindrical neck which is set in a depression or on a flattened area of the last septal face. Length, 0.70 milHmeter; maximum diameter, 0.44 millimeter. Plesiotype No. 4021, locality P2, Ponce formation. Rare at P2, P3, and P255 of the Ponce formation. Uvigerina mexicana bulbosa new variety Plate 33, figure 10 This variety differs from typical V. mexicana in being subglobular in shape, and broadly rounded, not tapering at both apical and apertural ends. Length, 0.54 millimeter; diameter, 0.48 millimeter. Holotype No. 4077, locality P3, Ponce formation. Rare at P3 of the Ponce formation. Uvigerina mexicana ranunculus new variety Plate 33, figure U Test stout, circular in cross section, more tapering at both ends than typical U. mexicana; maximum diameter about midway the length of the test; apical end with a flat, spine-like process formed by the union of several costae; other characteristics like typical 17. mexicana. Length, 0.92 millimeter; diameter, 0.50 millimeter. Holotype No. 4022, locality P2, Ponce formation. Rare at P2 of the Ponce formation. Uvigerina postica new species Plate 33, figures 3, 4 Test elongate, about twice as long as wide, bulbous, the later two- thirds converging to the apical end, enlarging rapidly from the apical end to the greatest width below the middle; apical end pointed, some- times with short apical spine; chambers in about 4 whorls, closely appressed and regularly triserial in the first third of the test, slightly inflated and tending to become biserial in the second third, and con- siderably inflated and tending to become uniserial in the final third of the test; sutures flush with the surface in the first third of the test, marked by clear shell material, somewhat depressed in the later two- thirds; wall finely perforate; surface of the apical and apertural ends provided with small spines which are not in definite lines; most of the test ornamented by fine, low, round longitudinal costae, not continu- ous across the sutures, about 20 on one side of the test or 13 in a width of 0.2 miUimeter; shoulders of last chamber round and sloping; aper- 432 SCIENTIFIC SURVEY OF PORTO RICO ture with a short, tapering neck, not set in a depression, without lip or with a very narrow phiaUne Up. Length, up to 0.66 millimeter; diameter, 0.30 millimeter. Form ratio (length over diameter) 1.9 to 2.28, averaging 2.1. Holotype No. 4146a, paratype No. 4146b, locality A86, Cibao formation. Common at A86 of the Cibao formation. This species is similar to U. striata d'Orbigny in the fine costae, but scarcely deserves comparison. The comparison with U. bulbacea is given under that species. The specific name postica refers to the enlarged posterior part of the test, above the pointed apical end.

Lower Oligocene, gulf coastal plain of U. S. and Mexico. Test regularly fusiform, over twice as long as wide, greatest width near the middle; chambers in about three whorls, closely appressed, regularly triserial to near the apertural end, where the chambers be- come biserial and tend to be uniserial; sutures slightly depressed, obscure; surface ornamented, from apex to apertural neck, with about 18 or 20 strong, sharp costae, about 5 in a width of 0.2 miUimeter, which curve considerably; some costae are confined to one chamber, others cross the sutures; aperture terminal, round, at the end of a short neck, which is not set in a depression, with small lip. Length, 0.73 milUmeter; width, 0.35 millimeter. Plesiotype No. 4020, locality P251, Ponce formation. Rare at P251 of the Ponce formation. This is one of the better characterized species of the genus, with its fusiform shape and part of the costae crossing the sutures. SIPHOGENERINA Schlumberger 1883 Siphogenerina costostriata new species Plate 34, figures 5a, b Test of medium size, slender, the early part conical, the later part somewhat compressed; the early part sharply rounded, gradually expanding to the broadly rounded apertural end; chambers triserial and closely appressed in the first third of the test, becoming biserial in GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 433 the middle third and uniserial in the final third, progressively more inflated from the middle to the oral end; sutures obscure in the first third, depressed in the later two-thirds; surface ornamented with fine striae in the first one-third of the test, about 20 in a width of 0.2 millimeter; the later two-thirds with thin, low costae, 5 to 6 in a width of 0.2 millimeter, between each pair of which there are 2 or 3 much smaller, raised striae; neither the costae nor striae cross the sutures; aperture oval, without phialine lip, at the end of a short neck, which is not set in a depression. Length, 0.78 millimeter; width, 0.26 milli- meter; thickness, 0.21 millimeter. Holotype No. 4147, locality P254, Ponce formation. Rare at P254 of the Ponce formation. This species has just passed from the Uvigerina to the Siphogenerina stage. It differs from described species of both genera in the two sets of costae, and in other ways. Siphogenerina cumingsi new species Plate 34, figures 6 and 7 Test elongate, subcylindrical ; apical end pointed in the more elon- gate, microspheric form, bluntly rounded in the stouter megaspheric form; triserial stage very short, uniserial stage with about 7 chambers which are about % as long as wide; sutures flush with the surface, curved adorally between the costae; wall ornamented by 7 to 8 longitudinal costae, each continuous the length of the test except for the last chamber; apical end spinose; triserial portion of megaspheric test with short costae intercalated between the primary costae; apertural end rounded with a short neck; aperture terminal, round, with slight phialine lip. Dimensions of average megaspheric form: length, 0.94 millimeter; diameter, 0.26 millimeter. Dimensions of figured microspheric form: length, 0.86 millimeter; diameter, 0.26 millimeter. Maximum size of microspheric form: length, 1.26 milli- meters; diameter, 0.30 millimeter. Holotype No. 3983, locality P3, paratype No. 3984, locality P2, Ponce formation. Holotype is megaspheric form; paratype micro- spheric. Rare at P3 and P255; common at P2 of the Ponce formation. Both megaspheric and microspheric forms occurred at all three localities. S. cumingsi differs from S. spinosa Bagg (1904. Md. Geol. Surv. Mio.; refigured by Cushman & Cahill, 1933. U. S. Geol. Surv. Prof. Pap. 175A) in the lower costae and more slender test in both mega- spheric and microspheric forms, and in the absence of spines on the 434 SCIENTIFIC SURVEY OF PORTO RICO costae. The lip is also less flaring. S. lamellata Cushman (1918. U. S. Geol. Surv. Bull. 676) has lamellae rather than costae. This species is named in honor of Professor E. R. Cumings, who, as head of the Department of Geology at Indiana University, has fostered scientific research for many years. Siphogenerina hubbardi new species Plate 34, figure 2 Test elongate, cylindrical, nearly circular in cross section; triserial portion about J^ the length of the test, 4 chambers in uniserial part of the test; apical end either blunt in what is evidently the megaspheric form, or pointed in the microspheric form; most specimens with small spinosities near the apical ends of the costae; chambers slightly in- flated, uniserial chambers broader than long; sutures depressed in early part of the test, only slightly depressed in later part; wall ornamented by about 20 longitudinal costae most of which are con- tinuous from chamber to chamber; aperture terminal, circular with rounded lip at the end of a definite neck. Total length, 1.00 milli- meter; diameter, 0.30 millimeter; length of neck, 0.06 millimeter. Holotype No. 3985, locality P2, Ponce formation. Common at P2, P3, and P255 of the Ponce formation. ;S. hubbardi differs from S. multicostata Cushman and Jarvis (1929. Contr. Cushman Lab. Foram. Res. 5) in that the costae are continuous from chamber to chamber and the apical spinosity is less pronounced. This species is named in honor of Dr. Bela Hubbard who has made important contributions to the stratigraphy and paleontology of Porto Rico.

Test small, elongate, subcylindrical to fusiform, 3 to 4 times as long as wide, greatest width in the later half of the test; uniserial chambers occupying nearly half the length of the test; chambers distinct, slightly inflated, uniserial chambers shorter than wide, except for the last chamber which is approximately equidimensional; sutures de- pressed; surface ornamented by 18 to 20 narrow, low, longitudinal costae which extend up to the base of the neck; costae on each chamber usually independent of those on adjacent chambers; costae somewhat spinose on triserial part of the test; apertural end tapering to a short neck; aperture terminal, circular. Length, 0.74 millimeter; diameter, 0.20 millimeter. Plesiotypes Nos. 3987a and 3987b, locality P254, Ponce formation. Rare at P2 and P254 of the Ponce formation. The Porto Rican specimens have the phialine lip broken off. ANGULOGERINA Cushman 1927 Angulogerina cibaoensis new species Plate 34, figures 12a, b Test small, short, thick, bulbous at the lower end, apical end pointed and rapidly expanding to the greatest width at about two- fifths of the length of the test from the apical end, thence tapering to the apertural end; test triangular throughout, with angled edges; chambers regularly triserial and closely appressed in the early part, becoming biserial and tending to become uniserial, not inflated; sutures indistinct, little depressed; surface smooth at apical and aper- tural ends, provided with 3 or 4 small, low costae on each face in the middle of the test, about 4 in a width of 0.2 millimeter; the costae do not cross the sutures; aperture oval, at the end of a short neck, with small lip. Length, 0.62 millimeter; width, 0.36 millimeter; form ratio 1.7. Holotype No. 3864, locaHty A86, Cibao formation. Common at A86 of the Cibao formation. This species is shorter than A. cooperensis^ with which it occurs, 'Hid lacks the apical costae. 436 SCIENTIFIC SURVEY OF PORTO RICO Angulogerina cooperensis Cushman Plate 34, figures 13a, b Angulogerina cooperensis Cushman (1935) U. S. Geol. Surv. Prof. Pap. 181: 42. pi. 16, fig. 9. Upper Eocene, South Carolina. Test of average size, slender, apical end pointed and rapidly ex- panding to the greatest width about one-third of the length of the test from the apical end, thence tapering to the apertural end, tri- angular throughout, with angled edges; chambers regularly triserial in the first third, becoming biserial and the final third uniserial, closely appressed but irregularly inflated; sutures indistinct, little depressed; wall finely perforate; surface ornamented with low, indis- tinct costae on the first two-thirds, disappearing on the final third, not crossing the sutures, 3 to 6 on each face of the test, 6 in a width of 0.2 millimeter; aperture at the end of a long neck, subtriangular, with slight lip. Length, 0.74 millimeter; width, 0.31 millimeter; form ratio 2.4. Plesiotype No. 4148, locality A86, Cibao formation. Rare at A86 of the Cibao formation. The Porto Rican form differs from the type figure of A. cooperensii^ in having the greatest width nearer the apertural end, and in having a longer neck. Such differences may be of varietal or even specific rank, particularly since the Porto Rican form is nearly twice as large as the type specimens from the Eocene. Angulogerina decorissima NEW species Plate 34, figures 8 to 10 Test small, short fusiform, tending to be bulbous, greatest width a Uttle below the middle of the test; triangular in cross section, sharply angled at the edges; chambers relatively few, closely appressed, flat on the faces of the test; sutures slightly depressed; surface ornamented by numerous striae which cover the entire test up to the base of the neck and are discontinuous from chamber to chamber; neck sub- triangular of moderate length; aperture terminal, round, with a slight phialine lip. Length of holotype, 0.53 milUmeter; diameter, 0.28 millimeter. Holotype No. 3865a, paratypes Nos. 3865b and 3865c, locality A21, Quebradillas formation. Rare at A21 of the Quebradillas formation. This species has a slight resemblance to A. albatrossi ornata Cushman (1932. Contrib. Cushman Lab. Foram. Res. 8), but is more regular GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 437 ill shape, with striae on all the chambers. It differs from A. occi- dentalis (Cushman) (1933. U. S. Geol. Surv. Prof. Pap. 175A) in having finer striae and less lobulate chambers with triangular cross section throughout the test. Angulogerina ponceana new species Plate 34, figures lla-c Test small, stout, IJ^ times as long as wide; apical end broadly rounded; apertural end truncate; in end view subtriangular with rounded angles; chambers few, 4 to 6, regularly triserial, somewhat inflated, overhanging previous chambers; sutures depressed deeply in some places and shallow in others, undulating, with the uneven chamber inflation producing a knotty appearance to the test; wall finely perforate; surface ornamented with 9 to 12 low, obscure costae, mostly confined to the early and middle part of the test, all fading out on the last chamber; aperture terminal, with short neck set in an en- circling depression in the last septal face, with slight lip. Length, 0.45 millimeter; thickness, G.33 millimeter. Holotype No. 4023, locality P254, Ponce formation. Rare at P254 of the Ponce formation. This species differs from A. naranjoensis Cushman and Bermudez (1937. Contrib. Cushman Lab. Foram. Res. 13: 16, pi. 1, fig. 56) in the shorter form, broadly rounded apical end, less inflated chambers, and in the presence of low costae. It is much like the paratype of that species (figs. 57, 58), which seems to be costate. The authors say in the original description (p. 17), ''wall generally smooth^', and in the discussion again, ''smooth wair\ The costae in the Porto Rican form are so small and inconspicuous that they might be overlooked.

Test small, elongate, elliptical to fusiform in shape; 6 to 8 chambers in the test, regularly alternating, increasing gradually in size, little inflated; sutures slightly depressed; surface unornamented; aperture in an oval depression on the side of the last septal face, consisting of a lunate opening with two small teeth on the lower side. Length, 0.66 millimeter; diameter, 0.16 millimeter. Holotype No. 4070, locality P2, Ponce formation. Common at P2 of the Ponce formation. P. elliptica differs from P. alternans Schwager (1866. Novara- Exped. Geol. 2: 238. pi. 6, fig. 79, which we here designate as the type of P. alternans; not fig. 80) in that the test has fewer chambers, is less tapering and is more rounded at the apical end. It differs from P. jacksonensis Cushman and Applin (1926. Bull. Am. Assoc. Petr.

Test smoothly ovoid, apical end slightly more pointed than apertural end; chambers uniserial, enlarging rapidly, last chamber completely embracing earlier chambers; aperture terminal, an arcuate slit with 442 SCIENTIFIC SURVEY OF PORTO RICO raised lip; shape of slit varies from a short arc to a short U or V shape. Length, 1.35 millimeters; diameter, 1.17 millimeters. Plesiotypes No. 3904a and 3904b, locaUty P2, Ponce formation. Rare at P3 and P255; abundant at P2 of the Ponce formation. E. abbreviata is, as the name indicates, much shorter in proportion than E. elUpsoides Seguenza (1859. Eco. Peloritano II. 5:). Family CAMERINIDAE Meek & Hayden 1865 OPERCULINELLA Yabe 1918 Operculinella sinuata new species Plate 36, figures 4a-c Test very small for the genus, compressed, biconvex, biumbonate, nearly bilaterally symmetrical; edge narrowly rounded but not keeled; periphery smooth; whorls about two, involute to umbos, only the last whorl exposed, part of the earlier whorl visible through the clear umbonal material; chambers 10 to 12 in the last whorl; sutures distinct, marked by clear shell material, flush with the surface, strongly curved, meeting the periphery with a small angle, recurved onto the umbo, making the sutures sigmoid in the last half whorl; the two sides of the test nearly identical; wall very finely perforate; aperture a small slit, with small upper lip, at the base of the septal face on the inner periphery, not extending beyond the edge of the test on either side. Diameter, 0.55 millimeter; thickness, 0.16 millimeter. Holotype No. 4067, locality A21, Quebradillas formation. Rare at A20 and A21 of the Quebradillas formation. There are few described species with which to compare this Porto Rican form. It is smaller and has fewer chambers than 0. dia Cole and Ponton (1930. Fla. Geol. Surv. Bull. 5).

Exterior.—Test discoid, eccentrically biumbonate, the central portion 2 to 3 times as thick as the broad, complanate portion; edge sharply rounded; surface ornamented with a smooth boss which is GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 443 surrounded by low, oval and elongate papillae, and with raised lines of transversely elongate papillae and discontinuous raised lines along the sutures in the later part of the test; the sutures between the chamberlets are less raised, but are frequently slightly raised at their outer ends and confluent with the raised sutures between the chambers; aperture not observed. Diameter of test, 4 to 6 millimeters; thick- ness, central part 0.8 to 1 millimeter; thinner edge, 0.33 to 0.4 milli- meter. Median section.—Chambers short, 20 or more in the last whorl, 0.16 to 0.22 millimeter long in the direction of coiling, broad radially and strongly and evenly curved, meeting the edge with a small angle; chamberlets rectangular, the later ones half as wide as long, 0.2 by 0.1 millimeter, alternating in position with those in prior and succeeding chambers, so that the walls between chambers are markedly zigzag; the earlier chamberlets are wider and shorter than the later ones, the earliest ones being highly arched (ogival) to trapezoidal in shape; pro- loculum spherical, 0.09 millimeter in diameter, followed by two oval chambers of nearly the same size. Vertical section.—The spherical proloculum and rectangular median chambers are covered with numerous laminae making up the lateral zones; the laminae are composed of vertical fibers of calcium carbonate, and are more transparent at the outer ends of the chambers, with indications of pillars radiating from the proloculum. Plesiotype No. 4149, locality L3C, San Sebastian formation. Rare at L3C and L5C of the San Sebastian formation. In some of the specimens the raised sutures between the chambers and between the chamberlets are more pronounced than in the figured specimen, but not as pronounced as in H, ocalana Cushman (1921. U. S. Geol. Surv. Prof. Pap. 128E: pi. 21). Family ORBITOIDIDAE Schubert 1920 In the San Sebastian and Ponce formations, there occur small specimens of orbitoids, 1 to 3 millimeters in diameter which are very much like Lepidocyclina parvula Cushman, and LepidocycUna (Nephro- lepidina) tournoueri Lemoine and Douvill6, as described and figured by Vaughan (1933. Smith. Misc. Coll. 89). While the specimens are insufficient for adequate study description and figures, they are suffi- cient to demonstrate the Oligocene age of the beds in which they occur. Lepidocyclina cf . parvula Cushman is rare at L4C of the San Sebas- tian formation, and common at P251 of the Ponce formation. 444 SCIENTIFIC SURVEY OF PORTO RICO Lepidocyclina (Nephrolepidina) cf . tournoueri Lemoine and Douville is rare at L4C of the San Sebastian formation, and at P251 of the Ponce formation.

Oligocene, Italy.— Nuttall (1933) Jour. Paleont. 7: 176. pi. 24, figs. 7, 9, 11-14. Middle Oligocene, Mexico. Exterior.—Test flabeUiform, irregularly discoidal, nearly equally biconvex, the initial end narrow with smooth outline, the outer margin serrate, due to the large median chambers which are not covered by lateral laminae; surface papillate, the apical portion with very small papillae, about 0.02 millimeter in diameter, the outer portion with papillae more variable in size, 0.03 to 0.08 millimeter in diameter, and the early middle portion with the largest papillae, about 0.1 millimeter in diameter. Only microspheric forms were found. Length, from 0.8 to 2.5 millimeters; width, 0.7 to 2.7 millimeters; thickness, up to 0.35 millimeter. Median section.—The coiled nucleoconch of an average specimen (1.3 millimeters in diameter) is located near the periphery at the apex of the test, and consists of a globular proloculum about 0.1 millimeter in diameter, with wall about 0.028 millimeter thick, followed by one to two whorls of chambers; the proloculum and a few slightly smaller chambers, subtriangular to rectangular in shape with radial dimension increasing gradually, are followed by spatulate chambers for a half whorl to a whorl, then by diamond shaped chambers for the remainder of the test. Longitudinal vertical section.—The median chambers are oval and appressed, about 0.1 millimeter in length and 0.15 millimeter in diameter, constituting about half the thickness of the test; the chamber walls are fibrous crosswise; the lateral laminae are rather thick and transversely fibrous, and traversed by fibrous pillars around the nucleo- conch, the pillars appearing at the surface as knobs. There is a light- colored structure at the outer edge of many of the median chambers. No apertures were observed in either median or vertical sections. Plesiotypes No. 4150a, 4150b, 4150c, and 4150d, locality L4C; and No. 4151, locality L6C, San Sebastian formation. Rare at L2C and L3C; common at LlC and L6C; abundant at L4C and L5C of the San Sebastian formation. Common at A86 of the GALLOWAY AND HEMINWAY, TERTIARY FORAMINIFERA 445 Cibao formation. Abundant at A79 of the Los Puertos formation. Rare at P2 and P4 of the Ponce formation. The presence of lateral laminae rather than lateral chambers places these specimens in the genus Miogypsinoides, The Porto Rican specimens are smaller than the French types of the species, but are of the same size as the Mexican specimens.
