TALLAHASSEE, FLORIDA, April, 1931. CALFORNIA STATE DIVISION l IES JUN 24 1931 San Fra c, California LETTER OF TRANSMITTAL To His Excellency, Hon. Doyle E. Carlton, Governor of Florida. SIR: I have the honor to submit herewith for publication the sixth scientific bulletin of this Department consisting of a detailed report or catalogue of the foraminifera contained in the formations of Florida of Pleistocene and Pliocene age. For comparative purposes conclu- sions resulting from studies of collections by Dr. Cole from formations of similar age occurring in other states within the Coastal Plain are included. Such comparisons have made this report much more in- clusive and I feel sure that it will serve a very useful purpose. These minute fossils have been found very helpful in working out strati- graphic problems in the more precise identification of geological horizons and with the progression of such detailed work the fossils contained in the formations of Florida are gradually becoming better known. Respectfully, HERMAN GUNTER, State Geologist. Tallahassee, Florida, April, 1931.

STORRS COLE, Dallas, Texas. ABSTRACT The Pliocene and Pleistocene formations of Florida contain characteristic faunal groups of foraminifera by means of which the individual formations may be recognized. These organisms also supply valuable information with regard to the depositional history. The Caloosahatchee marl Pliocene) contains the most varied and abundant fauna with many of the species found therein actually living at present in the West Indian region. It is indicative of shallow, warm water depositional conditions. The Charlton formation (Pliocene?) is represented by only one species and is evidently of brackish water type. Of the two Pleistocene formations discussed, the Fort Thompson has a fauna which is most closely related to the underlying Caloosahatchee marl. The fauna of the Anastasia formation is of shallow, relatively cool water type. The Florida Pliocene faunas are compared with those of the Waccamaw marl (North and South Carolina), while the Pleisto- cene faunas are compared with those of the Wadmalaw marl (South Carolina), the Chowan? formation (North Carolina) and the Talbot formation (Maryland). During the summer of 1929, through the kindness of Mr. Herman Gunter, State Geologist of Florida, I was able to make a considerable collection of Pliocene and Pleistocene foraminiferal material from that state. Later, that same summer I supplemented this material by additional collections for comparison purposes as far north as Mary- land. Additional Florida material has been sent me from time to time during the preparation of this paper by Mr. Gerald M. Ponton of the Florida State Geological Survey. The Pliocene foraminifera from Florida were collected from the Caloosahatchee marl,' including deposits which were formerly called Nashua,2 but are now included under the name Caloosahatchee. Material for comparison was collected from the Waccamaw3 formation of North and South Carolina. Samples were obtained also from the Charlton formation of Florida. This formation is of questioned Pliocene age. 1For a detailed description of the stratigraphy of Florida see: Cooke, C. W, and Mossom, S., "Geology of Florida", Florida Geol. Survey, Twentieth Ann. Rept., 1929, pp. 31-227. 2Ibid: p. 152. SVaughan, T. W., Bull. Geol. Soc. Amer., 1924, p. 742. 1 _ a FLORIDA GEOLOGICAL SURVEY-BULLETIN SIX The Pleistocene foraminifera were collected from the Fort Thomp- son and Anastasia formations. Comparative material was obtained from the Simmons Bluff, S. C., Pleistocene along the Neuse4 River and the Talbota formation of Maryland. Samples were obtained also from the "Miliolite limestone," Levy County, Florida, assigned by Cooke' and Mossom to the Pleistocene. NOTE:-Examination of the samples of the "Miliolite Limestone" collected by Cole and Ponton from near Ellzey and Otter Creek, Levy County, showed a more or less intimate mixture of Ocala limestone (Eocene) and Pleistocene material. The Eocene formation being represented by the echinoderms Eupatagus floridanus ar1l Laganum archerensis and the foraminifera Gypsina globulus, Coskinolina prob- ably C. cookei, and fragments of Operculinella willcoxi and Lepidocyclina, prob- ably L. ocalana. The PleistoceTre is represented by Chione cancellata and fragments of Mellita cf. pentaphora. .tfle'iiamerous specimens of the family Miliolidae are too poorly preserved for sp'ecifTc nfeticitation. It is not surprising that such an admixture of formations exists in this area; .The waves of the shallow Pleistocene sea could easily break up the soft Ocala limiestobn and:mix it with the material being laid down at the time. It,.is known that the Miliolite limestone is comparatively thin as several borrow-pits operated for grading roads liavepen~etrated the formation exposing the undisturbed Ocala limestone. In the pits referred to the greatest thickness noted was six feet.-G. M. PONTON. . The following is a.list of localities at which collections were made. If time had'pemnitted, minfy more localities could have been visited. However, it is felt that-a.sufficient number have been examined to give a representative cross-Aectio6nof the fauna. Station 1.

While the main emphasis in this paper will be placed on the Florida material, Mr. Gunter has very kindly allowed the writer to introduce as much comparative material from other states as is necessary in order to completely show the relationships of the foraminifera occur- ring in the Florida formations with those of the other Pliocene and Pleistocene formations of the Atlantic coastal plain. While foraminifera do not form a considerable portion of the material examined from any of the localities, by concentrating the material after washing, a sufficient number of specimens can usually be obtained. Even though the fauna of the Pliocene formations is much more varied than that of the Pleistocene, the Pleistocene samples generally contain more individuals of a given species. Most of the TE PLIOCENE AND PLEISTOCENE FORAMINIFERA OF FLORIDA 11 les recorded have their counterpart in the recent faunas, particu- that of the West Indian region. A few, however, have not as yet described in either the recent or the fossil faunas. Previous workers have not examined the Atlantic coastal plain ocene and Pleistocene deposits in much detail for fossil foraminifera. first notes on Pleistocene foraminifera are given by Bagg' in his port on "The Tertiary and Pleistocene Foraminifera of the middle dantic Slope." Later Clarks utilized Bagg's observations on the leistocene foraminifera of Maryland, listing four species. The most nsive and comprehensive work is that of Cushman' on the "Pliocene oraminifera of the Coastal Plain of the United States." Cushman has also published some short notes on Pleistocene foraminifera faunules from Panama."'" Recently, Cushman and Cole12 have published some thort notes on the Pleistocene foraminifera of Maryland. ;Bagg, R. M., Bull. Amer. PaL, voL 2, No. 10, 1898, pp. 1-54 (295.348), pis. 131-133).

FLORIDA GEOLOGICAL SURVEY-BULLETIN SIX THE PLIOCENE FORAMINIFERA The Pliocene faunas are much more varied than those of the over- lying Pleistocene, and seem to indicate much warmer conditions of deposition. The occurrence in the Caloosahatchee marl of such genera as Amphistegina, Archaias, Cymbaloporetta, Peneroplis, Sorites, and Vertebralina are evidence of warm shallow waters like those of the present West Indian region. As will be pointed out later, the Pliocene Caloosahatchee fauna is very similar to the present West Indian fauna. These genera just mentioned do not occur in the overlying Pleistocene, although many of the more hardy and adaptable forms like Elphidium incertum (Williamson) are found in both the Pliocene and Pleistocene. From a study recently published by Norton13 on the "Ecological Relations of Some Foraminifera" in which most of the samples used were from recent Florida or West Indian deposits, it is apparent that the typical Caloosahatchee and Waccamaw formations fall in his zones A and B (0-60 fathoms) with a temperature range of about 200-320 C. As will be pointed out in more detail later, the Waccamaw deposition took place under temperatures nearer the lower end of this range, while that of the Caloosahatchee was at least above 220 C. The depth was probably not over 16 fathoms, if the relationships as shown by Norton are correct. It is highly probable that without the climatic disturbances which accompanied the Continental ice sheet, the fauna of the Pleistocene of Florida would have been about the same as both the West Indian recent faunas and the Pliocene. It is apparent on studying these faunas, that the more tropical elements of the Pliocene fauna were forced farther south during Pleistocene time, while the more adaptable forms of the Pliocene remained, and comprise the fauna of the Pleistocene deposits in Florida. The species in the Pleistocene of Panama are more nearly like the Pliocene fauna than the Pleistocene of Florida. Cushman'4 reports such forms as Sorites marginalis and Peneroplis pertusus in the Panama Pleistocene. These are present in the Pliocene, but not the Pleistocene of Florida. The difference then between the Pliocene and the Pleistocene faunas of Florida becomes one of temperature and adaptability of species rather than the dying out and replacement by new species. This differentiation and adaptation was emphasized by the fact that the faunas in all cases were those of shallow water. This habitat would reflect climatic changes much more rapidly than the deeper, '1Norton, R. D., Bull. Scripps Inst. Oceanography, Tech. Ser., vol. 2, No. 9, 1930, pp. 331-388. 14Cushman, J. A., Amer. Geol., vol. 33, 1904, p. 266. THE PLIOCENE AND PLEISTOCENE FORAMINIFERA OF FLORIDA 13 more uniform waters of the outer continental shelf. Deeper-water genera and species are generally lacking or represented at the best by one or two individuals. In a comparison between the Pliocene faunas from the various localities studied, it is apparent that the fauna from the typical Caloosa- hatchee represents the warmest waters and is most like the present West Indian fauna. However, the differences between the Caloosa- hatchee and Waccamaw are not as strongly marked as believed by Cushman.15 While Archaias angulatus, Peneroplis proteus, Sorites marginalis and Vertebralina cassis are apparently confined to the typical Caloosa- hatchee, Amphistegina gibbosa, Cymbaloporetta squammosa, Planor- bulinella larvata, together with typical tropical Miliolidae, occur in the Waccamaw formation. The fauna of the "Nashua" apparently differs from both the typical Caloosahatchee and the Waccamaw. In the case of the Mollusca, the "Nashua" fauna more nearly resembles the Waccamaw than the Caloosahatchee, according to Mansfield.'1 Miliolidae are absent in all the samples from the "Nashua" examined by me. The most charac- teristic species occurring is Elphidium gunteri n. sp. Rotalias comprise nearly all the remaining individuals from these localities, except for a few specimens of Reussia spinulosa, Lagena clavata, and others as noted in Table I. It is surprising that more genera and species do not occur. The sample from Station 25 is different from other samples exam- ined. In the majority of its species, it resembles the Caloosahatchee fauna, but some of the species indicate Miocene age. It contains S Dyocibicides biserialis as its most abundant species, and this form was not found in any other samples. As it is impossible to absolutely determine the age of this sample from the foraminifera, I am including it with the Pliocene material, although a study of the molluscan fauna may establish its age to be Miocene. The only foraminifer found in the samples from the Charlton for- mation was Rotalia beccarii var. tepida. As this species is not diag- nostic, it is impossible to state from foraminiferal evidence what the age of that deposit is. It was probably deposited under very brackish water conditions which were entirely unsuited for foraminiferal life. 15Cushman. J. A.. U. S. Geol. Survey, Bull. 676, 1918, pp. 5-6. 16Mansfield. W. C., Florida Geol. Survey, Fifteenth Ann. Rept., 1924, p. 30. FLORIDA GEOLOGICAL SURVEY-BULLETIN SIX The following 44 species are common to both the Caloosahatchee marl and the recent West Indian faunas: Amphistegina gibbosa Peneroplis proteus Angulogerina occidentalis Planorbulina mediterranensis Archaias angulatus Pyrgo subsphaerica Articulina antillarum Quinqueloculina agglutinans Bolivina rhomboidalis costata Cancris sagra lamarckiana Cymbaloporetta squammosa poeyana Discorbis floridana Reussia spinulosa mira Rotalia beccarii orbicularis var. parkinsoniana subaraucana var. tepida Elphidium fimbriatulum Sigmomorphina undulosa var. advenum Siphonina pulchra discoidale Spiroloculina antillarum poeyanum var. angulata sagrum Textularia candeiana Globigerina bulloides floridana triloba mayor Globulina inaequalis Triloculina bicarinata var. caribaea Guttulina pulchella Loxostoma cf. mayor Nonion grateloupi Orbul'na universe circularis oblonga tricarinata Vertebralina cassis Virgulina punctata Certain species occur in the Waccamaw which have not been found in the Florida material. These are: Anomalina ammonoides (? Planulina ariminensis Eponides repanda Quinqueloculina cf. funafutiensis Faujasina carinata Sigmomorphina semitecta Guttulina costatula var. terquemiana lactea Spirillina decorate Planorbulinella larvata Spiroloculina planulata Cushman records the following species from the Caloosahatchee marl which have not been found by me. This difference is to be expected in view of the scarcity of certain species. Discorbis globularis Hauerina ornatissima Lagena semistriata Peneroplis discoideus Spiroloculina excavata Truncatulina ungeriana PLIOCENE AND PLEISTOCENE FORAMINIFERA OF FLORIDA 13 THE PLEISTOCENE FORAMINIFERA has been pointed out before in this paper, and can readily be on consulting the range table, the Pleistocene fauna is compara- 'limited in number of species, but often these are very prolific in rs of individuals at a given locality. Of the two marine Pleistocene formations of Florida studied in this aperr, the Anastasia has a much more varied and prolific fauna than that of the Fort Thompson formation. The foraminifera from the Fort Thompson are exceedingly scarce, but seem to indicate a close connection with the underlying Pliocene. Elphidium incertum, Elphidium sagrum and Rotalia beccarii var. ornata are the commonest forms found. It is of interest to note that Rotalia beccarii var. ornata, which is one of the commonest fossils in the Pliocene and Fort Thompson beds (Pleistocene) of Florida, is also found in the Talbot formation of Maryland, where it is exceedingly well developed and abundant. The species which especially characterize the Anastasia formation are Angulogerina occidentalis, Bolivina doniezi, Buliminella elegan- tissima, Elphidium incertum, Elphidium fimbriatulum var. advenum, Elphidium poeyanum and Rotalia beccarii var. tepida. Rarer species are Bolivina striatula, Cassidulina crassa, Elphidium sagrum, Lagena clavata and Nonion grateloupi. Norton1 points out that the genus Buliminella seems to be more or lees confined to deep cool waters in temperatures from about 20 to 8 C. This is the commonest genus observed in samples from the Anastasia Formation. As the other forms associated with it are typically of Shallow water type, it may be assumed that the temperature conditions were the controlling factor in its abundance. It is probable that the Temperature during the deposition of the Anastasia was higher than 8* C, but lower than 20. The depth is indicated as being about the same as in the Caloosahatchee and Waccamaw deposition. S. The fauna of Simmons Bluff, South Carolina, is very similar to tjthat of the Anastasia formation of Florida, as it contains Buliminella P4egantissima, Elphidium incertum, Elphidium fimbriatulum var. S'advenum and Rotalia beccarii var. tepida. Quinqueloculina lamarck- i'ana is also found in some numbers. The occurrence of Elphidium I.. acertum var. clavatum and Nonion cf. sloanii with the above, however, begins to suggest a connection between the Simmons Bluff fauna and Sthe more temperate fauna of Flanner's Bluff (Neuse River, N. C.) and 'of the Talbot formation of Maryland. The fauna of Flanner's Bluff, *TNorton, R. D., Bull. Scripps Inst. Oceanography, Tech. Ser., vol. 2, 1930, p. 348. 16 FLORIDA GEOLOGICAL SURVEY-BULLETIN SIX while comparatively poor in number of species and individuals, is closely related to that of Maryland. The Maryland fauna is decidedly distinct.'8 Elphidium incertum var. clavatum and Rotalia beccarii var. ornata are its commonest and most abundant species.

Length 0.38 to 0.86 millimeter. The type specimen of this species has many more peripheral spines than are found on the fossil specimens. Cushman has pointed out in his study of the Florida Miocene specimens assigned by him to this species that, while the Miocene specimens are very similar to the living ones, they are less accelerated, the early chambers usually being without spines. This is also true of the Pliocene specimens. This species occurs only rarely in the Caloosahatchee marl. Locality: Pliocene station 18. Florida Geol. Survey Cat. No. S-2058.

Test broader than long, the periphery broadly rounded; sutures fairly distinct; wall composed of rather large, agglutinated sand grains which give it a very rugose appearance; aperture slightly extended, teeth not observed. Length 0.58 millimeter. This species was observed only from localities along the Caloosa- hatchee River. In recent deposits, it is characteristic of warm, shallow waters of the West Indian region. Associated with it is Q. fusca H. B. Brady, another arenaceous form, from which it differs by its more rugose appearance and broadly rounded periphery. Locality: Pliocene station 18. Florida Geol.

Length 0.72 millimeter. Breadth 0.46 millimeter. This interesting species is common at some localities of the Wacca- maw formation, and appears only rarely in the Caloosahatchee. Its abundance may be of some practical use in serving to distinguish samples from these formations. Cushman reports this species from the Miocene of Florida. It apparently does not occur in the recent West Indian fauna. Localities: Pliocene stations 14 and 18. Florida Geol. Survey Cat. No. S-2061. QUINQUELOCULINA FUSCA H. B.

Length 0.40 millimeter. Width 0.28 millimeter. The Florida specimens seem identical with the figures given by Brady. This is evidently the species reported by Cushman as Q. bid- entata; but that form has a considerably different shape, as can readily be seen on a comparison of figures of it with the Florida specimens of Q. fusca. This is a rather common form in the Caloosahatchee marl on the Caloosahatchee River. Localities: Pliocene stations 17 and 18. Florida Geological Survey Cat. No. S-2062.

This species was reported by Cushman from the Waccamaw for- mation and the Caloosahatchee marl on Shell Creek. I have a doubtful specimen referable to it from Shell Creek. The Waccamaw formation had several typical specimens evidently belonging under this species. It also occurs in the Talbot formation of Maryland. In the recent faunas the typical Q. seminula seems to be confined to cool, shallow waters. It is therefore not surprising that it is not found in the typical Caloosahatchee and is a rare species in the Waccamaw. Localities: Pleistocene station 1; Pliocene stations 13 and 17. Florida Geol.

Diameter 0.41 millimeter. It is apparent on detailed study that the E. advenum of Cushman from the recent deposits of the West Indian area should be made a variety of the Florida Pliocene E. fimbriatulum. The general similar- ity between the Miocene, Pliocene, Pleistocene and recent forms re- ferred to these two types is striking, and at first it was believed they should be referred to only one species; but the chamber shape serves to differentiate them into two types: E. fimbriatulum, slightly small in size, with ridged, about equally sloped almost costae-like shaped chambers confined to the Miocene and Pliocene, and E. fimbriatulum var. advenum, ranging from Pleistocene to recent, with much more flaring, rather flat or gently rounded chambers, which are generally more greatly recurved on the anterior side than on the posterior.

This is probably the same form that Cushman referred to Poly- stomella craticulata var. in his Pliocene paper. It is very common in the "Nashua" equivalent of the Caloosahatchee marl in Florida. It is found rarely in the typical Caloosahatchee marl and in the Wacca- maw formation of the Carolinas. This form is evidently closely related to several of the recent species of Elphidium. From E. lanieri, it differs in its lesser number of cham- bers, more broadly rounded periphery, and the irregular raised areas of shell material instead of a single umbilical knob; from E. craticu- latum in its smaller number of chambers, smaller umbilical area and different arrangement of the bridgings. E. discoidale differs from E. gunteri by its slightly lobate margin, its sub-acute periphery and different shaped retral processes. This species is named in honor of Mr. Herman Gunter, State Geol- ogist of Florida, whose help made the publication of this paper possible. Localities: Pliocene stations 14, 21, 22, and 23.

Test nautiloid, compressed, the sides nearly parallel in end view, periphery broadly rounded, lobate, especially in the final 3 or 4 cham- bers (the degree of location often depending on the age and size of the specimen), umbilical region slightly depressed, sometimes with a slight knob or irregularities due to the ending of the slit-like sutures; about 9-10 chambers comprising the last evolution; sutures distinct, plainly marked by the openings which are in a single row, retral proc- esses few, distinct, the inner ends of the sutures slit-like; shell wall opaque, aperture a series of pores at the base of the apertural face with occasionally secondary pores scattered over the entire face. FLORIDA GEOLOGICAL SURVEY-BULLETIN SIX Diameter 0.61 millimeter. Thickness 0.20 millimeter. Cushman records this species as only occurring in the deeper, colder waters of the Atlantic, north of Hatteras. It occurs in the Pliocene, however, associated with a shallow, warm-water fauna. It is also an abundant species in the Pleistocene as far north as the Simmons Bluff locality. It can scarcely be mistaken, because of the character of the inner ends of the sutures to form slit-like depressions. Since Pleisto- cene times, it has evidently adapted itself to a different mode of environ- ment. This change was taking place during Pleistocene time, as this species is one of the prolific forms in the Pleistocene deposits which were evidently deposited in much cooler water than that of the Pliocene period.

Test of small size for the genus, composed of 10-12 chambers in the final evolution, compressed, slightly umbilicate, periphery broadly rounded; peripheral margin only slightly lobate; sutures distinct, slightly depressed, retral processes short, broad, about 15 in number; wall thin, smooth, translucent, finely perforate; aperture a series of round small pores at the base of the apertural face. This species, with E. incertum, is one of the commonest forms in both the Pliocene and Pleistocene of Florida. It can easily be recog- nized from that species by its smaller size, more rounded outline and different arrangement of retral processes.

Test of medium size for the genus, periphery broadly rounded, not lobate, except some specimens have the final chamber slightly inflated; sides convex, the test often appearing roughly spherical; umbilical region flattened rather than depressed; chambers fairly distinct, except in adults where the retral processes form such heavy ridges that the initial chambers are concealed; sutures only depressed in the final 2 or 3 chambers; marked by retral processes which form distinct ridges or welts; apertural face very narrow, apertures a row of small pores at the base of the apertural face. Diameter 0.48 millimeter. This is a very characteristic species, which occurs rather commonly in the Caloosahatchee and Fort Thompson formations, and much more sparingly in the Pleistocene deposits. A few specimens also have been found in the Waccamaw. It is easily recognized by its raised retral processes.

Diameter 0.67 to 1.16 millimeters. This is one of the restricted species apparently confined to the Caloosahatchee marl along the Caloosahatchee River and Shell Creek. It is exactly like recent specimens from the south coast of Florida in my collection, and fits Cushman's recent description so well that we have quoted the largest part of it.

Adult diameter 2.18 millimeters. THE PLIOCENE AND PLEISTOCENE FORAMINIFERA OF FLORIDA 39 A few specimens were found in the Caloosahatchee marl from the Shell Creek and Caloosahatchee River localities. It is comparatively rare, probably because of its relatively fragile test which could easily be broken and destroyed. In the recent faunas this species is characteristic of warm, shallow water. It is a rather common species in the recent West Indian fauna, where it occurs in an average water depth of about 42 feet with a fine sand as bottom material.

A very few specimens from the typical Caloosahatchee along the Caloosahatchee River and from the Waccamaw seem to be identical with the form described by Cushman from the Miocene of Florida.

BOLIVINA STRIATULA Cushman Plate 2, figure 9 Bolivina striatula Cushman, Carnegie Inst., Washington, Publ. 311, 1922, pp. 27-28, pl. 3, fig. 10. Original description: "Test elongate, gradually tapering from the somewhat rounded initial end to the broad apertural end; chambers numerous distinct, slightly inflated; sutures very slightly depressed; early portion of the test less compressed than the adult, the peripheral margin rounded in the young, sharply angled in the adult, early portion of the test with numerous longitudinal striations occupying about half the length of the test, following the chambers with a very fine reticulate pattern, the final chambers being smooth, punctate." Length 0.38 millimeter. FLORIDA GEOLOGICAL SURVEY-BULLETIN SIX As Cushman has already pointed out, this species is rather easily distinguished by its peculiar ornamentation.

Bolivina rhomboidalis Cushman, Carnegie Inst., Washington, Publ. 311, 1922, p. 28. Only one specimen of this characteristic species was found, that from the typical Caloosahatchee at Station 18. It is readily recognized by its triangular shape in front view and rhomboid shape in end view. It is identical with the excellent figure given by Millett. Cushman records this species in his Tortugas report; so it is not surprising to find it in the fossil condition. Locality: Pliocene station 18. Florida Geol. Survey Cat. No. S-2120. Genus LOXOSTOMA Ehrenberg, 1854 LOXOSTOMA GUNTERI Cushman Plate 2, figures 2, 3, 4 Bolivina karreriana Cushman (not Brady), U. S. Geol. Survey, Bull. 676, 1918, p. 8, pl. 2, fig. 5. Loxostoma gunteri Cushman, Florida Geol. Survey, Bull. 4, 1930, p. 47, pl. 8, figs. lla, b. Test elongate, compressed, periphery rounded, apical and apertural ends broadly rounded; chambers numerous, more distinct initially than aperturally; sutures, where showing, slightly depressed, but not affecting the ornamentation, limbate; test ornamented by numerous raised costae which run the length of the test, joining and branching freely, particularly towards the aperture; aperture terminal, rather large, elliptical and bordered by raised slightly recurved lips. Length 0.46 millimeter. Width 0.20 millimeter. This species differs from L. karreriana in having the initial end rounded whereas that species typically has a rather sharply pointed initial end with a strong apical spine. The costae on L. gunteri are finer and more numerous. It is evidently a shallow-water tropical species and seems to be confined to the Caloosahatchee marl on the Caloosahatchee River and Shell Creek in the Pliocene deposits. Cushman described this species from the Florida Miocene. Localities: Pliocene stations 17 and 18. Florida Geol. Survey Cat. No. S-2121.

Only one specimen was found which can be assigned to this species. It is evidently an adult specimen with the final chamber contracted, as has been noted by Cushman in his original description of the species. The depressed sutures and coarse punctations are also very character- istic. This species occurred in the Caloosahatchee marl along the Caloosa- hatchee River. Length 0.55 millimeter.

Verneuilina spinulosa Cushman, Carnegie Inst., Washington, Publ. 311, 1922, p. 28, pl. 3, fig. 11. The figured specimen was obtained from the Caloosahatchee marl along the Caloosahatchee River. It is apparently this species, although the spines are not as strongly developed as in some figures given of this species. Cushman described a specimen from the Wacca- maw formation as R. glabrata, because while it resembled R. spinulosa, it apparently had a more tapering form and was non-spinose. It is probable that the specimen in his possession was merely a variation of R. spinulosa. It was observed rarely in the typical Caloosahatchee, but occurred in some numbers in the "Nashua" equivalent. Localities: Pliocene stations 13, 19, 22 and 23. Florida Geol. Survey Cat. No. S-2123.

Mus., Bull. 104, pt. 4, 1925, p. 168, pl. 42, fig. 12. Test elongate, about 3 times as long as wide, widest just above the middle, ends rounded, initial end slightly more pointed than the apertural; chambers numerous, slightly inflated; sutures distinct depressed; wall ornamented by numerous longitudinal costae, which F FLORIDA GEOLOGICAL SURVEY-BULLETIN SIX under low power appear almost continuous, but under higher power are apparently slightly offset, the costae low, rounded, the costae to- ward the apertural end, tending to break up into spines on some speci- mens, on others continuous up to the neck; wall between the costae perforate; aperture circular at the end of a short cylindrical neck. Length 0.41 millimeter. The recent type of this species is from relatively deep water off the northeastern coast of the United States. The Florida specimens as- signed to this variety agree very closely with Cushman's figure of the recent form. It is very rare, a few specimens were found from Station 21 only. This is a different form from that which was referred to U. tenuistri- ata Reuss by Cushman from the Waccamaw marl. His figure indicates that the Waccamaw specimen is different from the Florida specimens, as it is much shorter and the costae are missing on the final chamber. It is interesting to record this variety in a relatively shallow-water fossil deposit. Because of its rarity and absence at other stations, it, is probable that it was washed in from the more open ocean. Locality: Pliocene station 21.. Florida Geol. Survey Cat. No. S-2124.

Angulogerina occidentalis Cushman, Florida Geol. Survey, Bull. 4, 1930, p. 50, pl. 9, figs. 8, 9. Test, minute, of different lengths, some being rather short, others rather elongate; in general, triangular in cross-section, although in the initial chambers little triangularity is shown, but the final chambers decidedly triangular; chambers distinct, sutures depressed; the final chambers tending to be added uniserially; wall ornamented with com- paratively large, high costae, which do not appear to be continuous; final chamber unornamented; aperture on the end of a tubular neck with a slight phialine lip. Length 0.32 to 0.38 millimeter. The type specimens of the species are from the Tortugas region. The specimens from Florida and the Carolinas agree exactly with Cushman's figures. His figured specimen in the Pliocene report from the Waccamaw River, South Carolina, is evidently generalized. It shows the final chamber costate. The specimens in my collection from THE PLIOCENE AND PLEISTOCENE FORAMINIFERA OF FLORIDA 45 Florida and the Carolinas do not exhibit this feature. Some of my specimens, particularly those from the Caloosahatchee River, are rather elongate, appearing the same as the one illustrated on Plate 5, figure 4 of the Tortugas report. It is undoubtedly only a form of A. occidentalis and this variation should be attributed to senescence as already noted by Cushman. This form is easily overlooked on account of its small size. Its occurrence indicates the close relationship between the Waccamaw and Caloosahatchee formations and the recent deposits of the Tortugas region. It also occurs in the Pleistocene deposits of Florida, so that its range is complete from Miocene to recent. This species is easily distinguished from A. angulosa (Williamson) by its rather coarse costae, the nudity of its final chamber and further that it does not show the regularity of triangular cross-section as the typical angulosa does.

There are a few specimens from one locality in Florida (Sta. 25) which are evidently closely related to Reuss' species.

Test rotaliform, plano-convex, the dorsal side strongly convex, the ventral side slightly concave, umbilicate; periphery slightly lobate, rounded; last whorl composed of 5-6 chambers, which gradually increase in size; sutures of the earlier whorls limbate, those of the outer whorl slightly depressed dorsally, more strongly so ventrally, not limbate on the outer whorl; wall coarsely punctate dorsally, finely punctate ventrally with the coarser punctations near the outer border; aperture an elongate, arched opening at the base of the last formed chamber, extending in to the umbilical area, sometimes with a thin lip. Diameter 0.29 millimeter. Height 0.17 millimeter. This species occurs in both the Caloosahatchee and Waccamaw formations.

Diameter 0.32 millimeter. This species is common to both the Caloosahatchee marl of Florida and the Waccamaw formation of the Carolinas. While never very abundant, it appears in most of the samples examined from these for- mations.

Plate 3, figures 9, 10 Test biconvex, dorsal side more strongly so than the ventral which is slightly concave; periphery lobate, rounded; 6 chambers comprise the last formed coil, final chamber very large; sutures curved, de- pressed, more strongly so ventrally than dorsally; dorsally, a marked, depressed line separating the outer whorl of chambers from the inner whorls; wall rather coarsely perforate; aperture a curved slit at the base of the last formed chamber, extending into the umbilicus; gen- erally covered by a slight lip. Diameter 0.32 millimeter. Type from Station 6, Bradenton, Florida (Pleistocene). Florida Geol. Survey Cat. No. S-2131. This species is similar in general outline to Discorbis obtusa (d'Orbigny) from the Miocene of the Vienna Basin. It lacks the marked tuberculate area shown on the ventral side of that species and the final chamber is not so extended into the umbilicus. This species occurs with slight variation in both the Pleistocene and Pliocene of Florida. It was found in greatest numbers of individuals in the Pleistocene deposits south of Bradenton. A few specimens referable to this species were found in the Waccamaw formation. It is easily recognized by the depressed area which separates the final whorl from the initial whorls. This species is named in honor of my wife, Gladys W. Cole, to whom most of the credit for organizing the material for this paper must go.

Test unequally biconvex, dorsal side somewhat arched, the ventral side flat or slightly concave; periphery not lobate initially, but the final two or three chambers slightly lobate, not keeled, bluntly rounded; sutures oblique, curved, depressed, limbate both dorsally and ventrally except the final 2-3 chambers which do not have limbate sutures; test composed of about 2.5 to 3 coils with generally 6 chambers in the final evolution, the final chamber occupying about one-fourth the area of the test; walls with numerous rather coarse punctae; aperture a narrow slit at the base of the last formed chamber extending from the periphery well into the umbilicus, covered by a slight projecting lip. Diameter 0.44 millimeter. This is a very pretty species, which is found in both the Waccamaw ____ FLORIDA GEOLOGICAL SURVEY-BULLETIN SIX and Caloosahatchee formations. While it is generally rather rare, enough specimens were obtained from most localities to give a complete suite. Upon comparison of the fossil material with recent material at the Cushman laboratory, they were found to be identical. This species furnishes a further connection with the Pliocene of Florida and the recent West Indian fauna. Cushman also records it from the Miocene of Florida.

Test small, plano-convex, the ventral side flat or slightly concave, the dorsal side strongly concave; 6 chambers comprising the last volu- tion; sutures distinct, depressed, more strongly so dorsally than ven- trally; chambers extend into the center ventrally so that there is no marked umbilicus; wall deeply and coarsely punctate dorsally, giving a very rugose appearance, ventrally finely punctate, smooth; periphery subacute; aperture a narrow slit on the ventral side of the final chamber extending from the periphery into the small umbilical area. Length 0.24 millimeter. Width 0.20 millimeter. This species was described by Cushman from the Caloosahatchee marl on the Caloosahatchee River. It is very rare, and is represented by only two specimens in the present collection. It is easily recognized by the coarse punctations on the dorsal side. Locality: Pliocene station 18. Florida Geol.

Test conical, trochoid, convex dorsally, concave ventrally, peri- pheral margin angular; 3 to 5 chambers showing in the last evolution, chambers elongate; narrow; sutures indicated by extremely fine lines nearly flush with the surface of the test; strongly oblique; recurved; wall smooth, very finely perforate; aperture a small slit at the base of the last chamber, opening into the umbilicus. Diameter 0.28 millimeter. This species was found in both the Caloosahatchee marl and the Waccamaw formation. Cushman reports it only from the Caloosa- hatchee.

Foram. Res, vol. 6, pt. 4, 1930, p. 100, pl. 13, figs. 15a-c. Test biconvex, the dorsal side generally more convex than the ventral which has a tendency to be slightly flattened, 10-12 chambers comprising the final whorl; sutures covered by a raised ridge of clear shell material, both dorsally and ventrally; umbilicus distinct, gen- erally filled with a plug of clear shell material which projects slightly beyond the-general surface of the test; aperture a small arched opening at the base of the final chamber, extending into the umbilicus. Diameter 0.48 millimeter (Pliocene, Fla.) to 0.67 millimeter (Pleis- tocene, Md.) This variety may be deserving of specific rank, as it has features which make it very distinctive. It is a rather common fossil in the Caloosahatchee and Fort Thompson formations. It reaches its best development in the Talbot formation of Maryland (Pleistocene). Cushman, in his Pliocene paper, considers it a tropical variety of R. beccarii, but it may be that other environmental conditions as well as warm water give rise to such modifications. The Maryland deposit must have been laid down under much more temperate conditions than either the Caloosahatchee or Fort Thompson formations. It is surprising that this form is very rare or lacking in the other Pleistocene deposits of Florida. It tends to show how much a form may be affected and the localization and migrations which may take place in faunas and individual species.

Rotalia beccarii var. parkinsoniana Cushman, Florida Geol. Survey, Bull. 4, 1930, p. 56, pl. 11, figs. 3a-c. As Cushman has pointed out the "variety differs from the typical in the number of chambers which in the variety rarely have more than _ _ FLORIDA GEOLOGICAL SURVEY-BULLETIN SIX ten in full grown specimens, the shorter broader chambers on the ven- tral side, the almost entire lack of beading at the sides of the chambers, and the lack of thickening of the sutures on the dorsal side." Diameter 0.52 millimeter. While this variety is evidently distinct, specimens referred to it approach the type species from Rimini on the Adriatic. Fig. 5, given by Cushman (Contr. Cushman Lab. Foram. Res., vol. 4, pt. 4, 1928, p. 106, pl. 15) in the series of type material of R. beccarii, is very close to the Florida specimens referred to this variety. This is rather a common form in the Pliocene and rare in the Pleis- tocene of Florida.

Roralia beccarii var. tepida Cushman, Carnegie Inst. Washington, Publ. 344, 1926, p. 79. pl. 1. Test small, trochoid, almost equally biconvex, 6-8 chambers com- prising the final whorl; periphery broadly rounded; sutures of the final coil depressed both dorsally and ventrally, more strongly so ventrally, limbate on the inner whorls dorsally; umbilicus open, pro- nounced, the ends of the chambers of the final whorl produced into a point which projects slightly into the open umbilicus; wall smooth, finely punctate; aperture a narrow slit beneath the inner angle of the last formed chamber. Diameter 0.46 millimeter. This is a common species in both the Pliocene and Pleistocene of Florida. It is identical with the recent variety described by Cushman from the West Indian region. It is quite similar to young megalo- spheric forms from Rimini (Cushman, Contr. Cushman Lab. Forams. Res., vol. 4, pt. 4, 1928, p. 107) when compared with type material which Dr. Cushman kindly supplied me. As no typical R. beccarii are found associated with this form which is evidently an adult, the varietal distinction is warranted. It shows very little change throughout either its vertical or horizontal range in the material examined by me.

THE PLIOCENE AND PLEISTOCENE FORAMINIFERA OF FLORIDA 51 ROTALIA CALOOSAHATCHEENSIS, n. sp. Plate 3, figures 1, 2 Test small, biconvex, strongly so on the dorsal side, ventral side very slightly convex; umbilical area with a distinct but small plug of shell material; periphery acute, thickened to form a narrow carina; six chambers comprise the last formed whorl, indistinct on the dorsal side, but plainly marked ventrally; sutures deeply depressed ventrally, straight radial, indistinct dorsally, not depressed, slightly curved; wall coarsely perforate, the perforations more plain ventrally; aperture a narrow slit at the base of the last formed chamber extending toward the umbilicus. Diameter 0.40 millimeter. Type from Station 18, Ayer's Landing on the Caloosahatchee (Pliocene). Florida Geol. Survey Cat. No. S-2139. This species is somewhat similar to Rotalia turbinata Cushman and Valentine, but differs in having a much smaller umbilical plug and a much more pointed dorsal spire. The ventral sutures are also more nearly radial. This is a rare form only found at Sta. 18. It is remarkably like the figure given by Cushman for Discorbis vilardeboana, in his Pliocene paper, although his description would not fit R. caloosahatcheensis. The figure given by Cushman of his Pliocine form is considerably dif- ferent from d'Orbigny's figure of D. vilardeboana.Y2 Subfamily Siphonininae Genus SIPHONINA Reuss, 1849 SIPHONINA PULCHRA Cushman2t Plate 4, figure 2 A young specimen evidently referable to this species, was found at one station in the Caloosahatchee marl along the Caloosahatchee River.

Test biconvex, longer than broad, the ventral side generally the most convex, about 6-7 chambers forming the last coil, these chambers increasing in size so that the final one occupies at least a fourth of the area of the test; sutures distinct, nearly flush with the surface dorsally, ventrally markedly depressed; peripheral margin of the test sharp, angulate, in some specimens bearing a slight keel, lobate; wall smooth, very finely perforate; aperture a narrow slit at the base of the final chamber in the umbilicus concealed by a thin plate of clear shell material which extends out over the umbilicus from the last chamber. Length 0.49 millimeter. Width 0.38 millimeter. This is a rather rare species but has been found both in the Wacca- maw and Caloosahatchee formations. Specimens referred to this species from the Marianna limestone are found to be identical with our Pliocene specimens. Cushman has also reported this species from the Miocene of Florida. Thus with the exception of the Pleistocene strata of Florida, this species has a continuous range from Oligocene to recent in Florida. That this species occurs in both the Caloosahatchee and Waccamaw formations, is considered additional proof that the two were deposited under nearly like conditions.

Family AMPHISTEGINIDAE Genus AMPHISTEGINA d'Orbigny, 1826 AMPHISTEGINA GIBBOSA d'Orbigny Plate 5, figure 14 Amphistegina gibbosa d'Orbigny, in De la Sagra. Hist. Fis. Pol. Nat.

Test unequally biconvex, the dorsal side strongly convex, composed of from 12-14 chambers in the final evolution; sutures of clear shell material, radiating outward on the dorsal side from a small knob of clear shell material, but strongly recurved and angulate near the bor- der; ventrally divided into two lobes; surface of test smooth except THE PLIOCENE AND PLEISTOCENE FORAMINIFERA OF FLORIDA 53 near the aperture where it is strongly papilate; margin of test sub- angular; aperture simple, rotaliform. Diameter 1.19 millimeters. This form appears to be a valid species rather than a form of A. lessonii, which is generally figured as being nearly biconvex with about 25 chambers in final evolution. While the sutures are angled near the periphery, they are not represented as being so much so as in A. gibbosa. The margin of A. lessonii is also more bluntly rounded than is the case in our specimens. This is a characteristic form in both the Caloosahatchee and Wacca- maw formations, but it has not been found in the Pleistocene deposits. This fact of its occurrence in the Pliocene and not in the Pleistocene is one of the points on which is based the conclusion that the Pliocene deposition occurred under more tropical conditions than the latter deposits.

Test subconical, trochoid, dorsal side forming a cone of various heights, ventral side concave, consisting of 5-7 chambers widest at the periphery, bluntly pointed in the umbilicus, constricted very slightly in the center; umbilical area marked; dorsal chambers rather irregular, smallest at the top of the cone; margin of the test irregularly lobate; sutures depressed, distinct; wall rather coarsely perforate; aperture consisting of rounded pores along the ventral sides of the chamber. Diameter 0.40 millimeter. This species was found in the Pliocene deposits of Florida and the Waccamaw formation. It is a characteristic species in recent deposits of warm, shallow-water type. The apertures are apparently of two types: one, the rounded pores leading through the ventral surface from one chamber to the next and second, a larger aperture opening directly into the umbilicus, observed only in the final chambers.

Test small, biconvex, oval in outline, periphery broadly rounded; chambers comparatively few, inflated; sutures slightly depressed; wall smooth, very finely perforate; aperture a long narrow slit just below and nearly parallel with the periphery of the test. Length 0.17 millimeter. This species occurs in some numbers at several stations in the Caloo- sahatchee formation. It also occurs sparingly at some stations in the Waccamaw formation of North and South Carolina and the Pleistocene of Florida. With it occur specimens which are referable to Cassidulina laevigata d'Orbigny var. carinata Cushman.

Length 0.20 millimeter. Width 0.14 millimeter. This is a rare species. While it agrees in general with Cushman's description and figures, there are some points of difference. The Flor- ida specimens from the Caloosahatchee marl appear to be slightly less compressed, and the arrangement of the final chambers is slightly different. It is felt best to refer it to this species for the present, how- ever, on account of the general agreement with this species. Locality: Pliocene station 21. Florida Geol. Survey Cat. No. S-2146. Family GLOBIGERINIDAE Subfamily Globigerininae Genus GLOBIGERINA d'Orbigny, 1826 GLOBIGERINA BULLOIDES d'Orbigny A few specimens which can be considered under this species have been found in both the Pliocene and Pleistocene.

Test relatively large, plano-convex, the dorsal side flat, the ventral side strongly convex, periphery subangular, 7 to 8 chambers in the last formed whorl; sutures slightly depressed initially, strongly de- pressed between the last formed chambers, limbate in the initial por- tion of test; a definite umbilicus on the dorsal side, a smaller umbilical area on the ventral side; a definite backward projection or lip on each chamber which projects into and over the umbilicus, these projections slightly overlapping; surface smooth, finely punctate; aperture peri- pheral, a rather large curved opening, with a definite lip and extending ventrally as a narrow slit. Diameter 0.52 millimeter (Florida) to 0.96 millimeter (South Caro- lina). This species raises the question as to generic classification. It is of intermediate type similar to Cibicides americanus. The type of aper- ture in A. basiloba seems to warrant placing it under A4nomalina rather than Cibicides. This striking, easily recognized species occurs in both the Wacca- maw and Caloosahatchee formations. It was described by Cushman from the Miocene, and is one of the connecting species ranging from the Miocene to the Pliocene in Florida.

Length 0.46 millimeter. Width 0.35 millimeter. Some of the Florida specimens from both the Pleistocene and Pliocene evidently belong under this species. The specimens which I have from the Waccamaw formation (Sta. 14) apparently should be placed under C. advenus (d'Orbigny) rather than C. lobatulus. The sutures of C. advenus are not limbate, they are markedly depressed and the peripheral margin is decidedly rounding.

Test fairly large, in adults composed of two distinct portions, the early portion coiled appearing like Cibicides, the latter portion made up of spreading, biserial plano-convex chambers, the dorsal, attached side flattened; 6-8 chambers show in the initial coil, these chambers not inflated, sutures depressed ventrally, dorsally flush with the surface, limbate; chambers of the biserial portion large, inflated, sutures markedly depressed ventrally, about flush with the surface dorsally; wall coarsely perforate; aperture in the uncoiled portion peripheral or slightly dorsal, in the uncoiled portion an elongate slit at the outer edge of the chamber at the line of attachment. Length 0.75 millimeter. Cushman and Valentine described this new genus and two species, D. biserialis and D. perforata, from the recent fauna of the Channel Islands of Southern California. Most of our specimens appear more nearly like D. biserialis, although some resemble the other species. In our material there seems to be some graduation of forms and we believe that these two species are only different stages of one form. This interesting form is recorded from only one locality (Sta. 25), but it occurred in some numbers. It suggests some relationship between the Pliocene fauna of Florida and the recent fauna of the west coast. Dr. Cushman informs me that this genus occurs also in the recent fauna of the Southern Atlantic Coast. It has been reported previously by Cushman from the Miocene of FLORIDA GEOLOGICAL SURVEY-BULLETIN SIX Florida. Locality 25, as indicated in the introduction, is the only station from which I have this form. It may prove later to be Miocene in age, but the assumption now is that it is early Pliocene.

Test adherent in life, at least in the young, piano-convex, dorsal side flattened, ventral side slightly convex; early chambers distinct spiral, later ones irregularly annular in arrangement, inflated in ventral view; ventral sutures markedly depressed, particularly be- tween the last formed chambers; wall rather coarsely perforate; apertures simple with a slightly raised lip. Diameter 1.02 millimeters. This is a very rare species and is represented by only a few speci- mens from the typical Caloosahatchee. Planorbulinella larvata was noted in the Waccamaw formation. It is easily differentiated from Planorbulina mediterranensis by the development of the tubercles over the central area of the test which makes the sutures indistinct. Planorbulinella larvata, like Planorbu- lina mediterranensis, is essentially a shallow warm water type and serves to indicate the similarity in deposition between the Waccamaw and Caloosahatchee formations.
