LAGENIDAE BY JOSEPH AUGUSTINE CUSHMAN Of the Boston Society of Natural History WASHINGTON GOVERNMENT PRINTING OFFICE 1923 pik wit he aniey bl fi Rew hy n 6 INTRODUCTION. This paper is the fourth part of a work the intent of which is to describe and illustrate the Foraminifera of the Atlantic Ocean, especially those species which have occurred in the waters adjacent to the shores of the United States, including the whole of the Gulf of Mexico and the Caribbean Sea, that being the area in which most of the work of the vessels of the United States engaged in dredging work has been done. This part includes only the family Lagenidae. The first part, issued in 1918, included the family Astrorhizidae. The second part, issued in 1920, included the family Lituolidae. The third part, issued in 1922, included the family Textulariidae. The fifth part will be devoted to the families Chilostomellidae and Globi- gerinidae, and further volumes will take up the remaining families of the Foraminifera as they are represented in the Atlantic Ocean.

Description —Test elongate, slender, the central portion subcylin- drical, the ends rather tapering, apertural end with a slightly thick- ened lip, opposite end closed; wall translucent, smooth. Length up to 1.50 mm. 16 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. Distribution—The only station from which I have had material that can be referred to this species is off the northern coast of South America, east of Trinidad. There are a few records for it off the 3ritish Isles, and Goés records it from off Greenland and Spitz- bergen. There are a few scattered records for it elsewhere than in the Atlantic. This has probably been confused with L. gracillima (Seguenza). This differs from Z. gracillima in the more cylindrical body, and much shorter projections at the ends. The test is also thicker and less transparent. Lagena elongata—material examined. h Bot- Dept No. of ; tom Cat. | Coll. of— | speci- | Station. Locality. in | tem- | Character of | spundance.

The only records for this species are from off the coast of the British Isles, Chaster’s figure being from off Southport, and those of Heron-Allen and Earland from Goldseeker dredgings off Noss Head, Moray Firth, 70 meters (38 fathoms), and other stations off the coasts of Scotland and Ireland. LAGENA FASCIATA Egger. Heron-Allen and Earland* record this species as abundant at most of the stations in the Clare Island region, and also report it as * Proc. Roy.

Lagena felsinea CUSHMAN, Bull. 71, U. S. Nat. Mus., pt. 3, 1913, p. 10, pl. 4, fig. 1. Description—Test elongate, subcylindrical, arcuate in side view, especially toward the apertural end, aboral end broader, rounded, or slightly acute; wall thin, smooth; aperture eccentric, rounded, with a long entosolenian neck somewhat inflated at its inner end. Length about 0.70 mm.; diameter about 0.25 mm. Distribution—Specimens which can be referred to the above species occur at several stations off the northeastern coast of the United States, with a single specimen from A/batross D2160, in the Caribbean. These specimens are very similar to that which I have figured from the North Pacific, and which Sidebottom has figured as Lagena apiculata from the Southwest Pacific. Cat.

Description.—‘ Test pyriform or flask-shaped, broad at the base, compressed; ento- or ectosolenian; furnished with a deep vertical wing, encircling the oval base; the wing traversed by parallel tubuli, and sometimes fringed at the free margin.” Length, 0.42 mm. Distribution.—TYhere are numerous records for this species from about the British Isles and elsewhere, but I have seen no specimens referable to it from the western Atlantic Albatross collections. LAGENA FLINTIANA, new species. Plate 3, figs. 11-13. Lagena orbignyana Fuinr (not Seguenza), Rep. U. S. Nat. Mus., 1897 (1899), p. 308, pl. 54, fig. 4. Description—Test somewhat compressed, longer than broad, the basal end broadly rounded, the apertural end much drawn out, body of the test rounded, completely encircled with a thin single keel, inside of which is a slight thickening of the test, but which does not stand up into a prominent ridge of any extent; wall translucent ex- cept for the peculiar thickenings which occur about the border of the body of the test, and especially across the base where the entire wall becomes clouded, as a result apparently of numerous small thickenings which are abundant in that particular portion; aperture tubular, entosolenian, but with an elongate tube in the body cavity. Length up to 0.75 mm. Distribution —Type-specimen (U.S.N.M. Cat. No. 19064) from Albatross station D2144, in 896 fathoms (1,639 meters), in the Carib- bean. Flint records this species as Lagena orbignyana Seguenza, but a study of the material from his station shows that he had a very different species. His stations are in the northern part of the Gulf of Mexico, in the Caribbean, between Cuba and Yucatan, off Panama, and west of the Windward Islands. I have had numerous specimens from these same regions. While it is impossible to say without con- sulting Brady’s original material, it seems probable that the speci- mens he records as Lagena orbignyana from off the Virgin Islands and off the coast of Brazil are the same species.

LAGENA FORFICULA Heron-Allen and Earland. Plate 3, fig. 10. Lagena forficula HeErRon-ALLEN and HARLAND, Proc. Roy. Irish Acad., vol. 31, pt. 64, 1913, p. 87, pl. 6, fig. 11. Description— Test free, consisting of a compressed oval cham- ber, furnished with a long neck, at the extremity of which is a phialine rim produced sideways into two short recurved hooks. The base of the chamber is furnished with two solid spines curving in- ward like the pincers of an earwig, from which we have named the species. “Total length, including neck and basal spines, 0.24 mm.; basal spines, 0.05 mm. in length; chamber, 0.12 mm. long, 0.08 mm. broad; neck, 0.07 mm. long; breadth across apical hooks, 0.08 mm.; maxi- mum breadth of shell across basal spines, 0.09 mm. “A single specimen of this extraordinary little form from Station 13. Broken individuals have been observed at one or two Gold- seeker stations in the Moray Firth. “Our species may be compared with that figured by Mr. Millett in 1901 (Journ. Roy. Micr. Soc., pl. 8, fig. 21) described as ‘L. marginata (Walker and Boys) var., very rare.’ It agrees with Mr. Millett’s specimens in the long neck with recurved spines at the oral extremity, but differs in the shape of the chamber, which is a com- pressed oval, whereas Mr. Millett’s specimen was a marginate form, and also in the presence of the strongly curved aboral spines. These are entirely wanting in the Malay form, the aboral extremity of which terminated in a short, blunt process, outgrowing from the carina. “The relationships of our species are evidently much closer to L. laevigata than to L. marginata, to which Mr. Millett referred his: specimens. The presence of the long neck with recurved oral spines, common to both forms, is, however, very noticeable.” The above seems to be the only reference for this peculiar species. 20 BULLETIN 104, UNITED STATES NATIONAL MUSEUM.

Trans., vol. 155, 1865, p. 348, pl. 13, figs. 387 a, b; pl. 16, figs. 10 a, b. Description—Test subspherical, smooth; aperture either stellate or a fissure with an entosolenian neck; wall thin, usually trans- parent, but sometimes thicker and nearly opaque, white. Length up to 0.50 mm. Distribution.—Specimens of typical Lagena globosa seem to be rare in the western Atlantic. I have had but a few specimens, and the stations are widely scattered from off the northeastern coast of the United States to the Caribbean. There are numerous records for the species, as the above synonymy shows. Specimens seem to be most common in fairly deep water, although about the British Isles the species seems to occur at moderate depths. It is a question whether or not a single species is really represented by all these specimens recorded. According to the descriptions, the apertural characters are very variable, a thing which does not usually occur, even in Lagena. It is also to be suspected that some of the forms referred to this species are really the initial chamber or proloculum of Polymorphina or other multilocular genera of the Lagenidae. A varietal form with a much larger test and thicker walls occurs at a few stations. Lagena globosa—material examined. : Bot- Depth No. of : tom na Coll. of— | speci- | Station.

Length up to 0.60 mm. ; Distribution.—This species, originally described by Williamson, oc- curs in its typical form at many stations about the British Isles. It is recorded at very many localities elsewhere, but an examination of what few figures are given shows many different forms. I have seen sritish material from off the southwest of Ireland, and have one specimen from A/batross station D2534, in 1,234 fathoms (2,257 meters), off the northeastern coast of the United States, which seems typical.

They are mostly from the northeastern coast of the United States, with two stations off southern Florida. In the Summary of Results of the Challenger Expedition specimens are recorded from several Challenger stations in the Atlantic; one of these is off the eastern coast of the United States in the same general region from which the Albatross material came. Another is off the West Indies. Two others are in the South Pacific, westward from the mouth of the Rio la Plata. There are numerous records for it off the British Isles. Goés records it from Spitzbergen and also from the Caribbean. There are records for it from the Mediterranean, the Antarctic, the Kerimba Archipelago, off New Zealand, and elsewhere. There seems to be a question as to whether this is really a very widely distributed species or whether, being of a smooth type with very few distinguishing characters, there may be several forms included under this name. In the Gulf of Mexico there is a varietal form which has very numerous very fine costae, which are so fine and close together that it is difficult to make them out except with a considerable magnification. In their general shape they are similar to the smooth forms from the Atlantic coast of the United States. Lagena gracillima—material examined. Bot- Depth No. of ° tom = Coll. of— | speci- | Station.

Description—Test pyriform, base semicircular, apertural end somewhat drawn out, with a short neck; surface ornamented by rather regular hexagonal reticulations, the sides of the hexagons ver- ticals, the angles pointing toward the ends of the test. Length up to 0.25 mm. Distribution—Williamson originally described this species from off the Shetland Islands. As the above references show, it is recorded from many stations about the British Isles and comparatively few elsewhere. The European material that I have seen, especially from off the southwest of Ireland, is very typical and abundant. There are a few specimens from the western Atlantic which I have referred rather questionably to this species. They differ from the typical British form in either their slightly different shape, or in the rela- tive size of the reticulations. The typical British material, so far as I have seen, is of the type given by Williamson, that is, the pyriform test with a broadly rounded initial end, the short neck, and the deep reticulations with the peculiar arrangement already noted in the description above. 26 Sdddd P tintntn BULLETIN 104, UNITED STATES NATIONAL MUSEUM.

Description —Test globular or pyriform, usually not compressed, neck elongate, thin, slender; wall thin, clothed with delicate spines uniformly distributed over the test. Length 0.40-0.80 mm. Distribution.—Spinose specimens of Lagena seem to be rare in the western Atlantic. I have had specimens from but two stations, FORAMINIFERA OF THE ATLANTIC OCEAN. OT D2144 in the Caribbean, off Panama, and D2150, in the Caribbean, off Yucatan. Flint records specimens from the northern part of the Gulf of Mexico and in the Caribbean, west of the Leeward Islands. Brady’s Atlantic Challenger records, except for one off the western coast of Africa, are all within this same faunal region, off the coast of Brazil, off the West Indies, and off Bermuda. There are numer- ous records for the species about the coast of the British Isles. From the large number of records and the different forms figured it is quite probable that a closer study of the hispid forms of Lagena will show definite species or varieties with definite geographical limits.

FORAMINIFERA OF THE ATLANTIC OCEAN. 29 thin specimens or opaque in more thickened ones, along the lateral margins usually clear even in thickened specimens; aperture elon- gate, fairly narrow, connecting with the interior by a fairly long entosolenian neck. Length up to 1 mm.; breadth slightly less. Distribution.—It is strange that this species which is apparently so common in many parts of the world has not occurred in its typical form in the western Atlantic collections. It seems to be abundant about the British Isles. LAGENA LAEVIS (Montagu). Plate 5, fig. 3. There are very numerous records for this species, covering most of the areas from which foraminifera have been recorded, but a reference to the various forms figured will show that many different smooth forms have been included under this name. Such specimens are not recorded in the Albatross collections, although there are numerous smooth forms which might well fit some of the figures given for this species. LAGENA LAEVIS (Montagu), var.

Description.—Variety differing from the typical in the form of the test which is globular or somewhat cylindrical, the neck slender, test with the sides parallel, the surface of the test with numerous thickenings giving a clouded appearance, almost subspinose. Length up to 0.80 mm. Distribution.—Type-specimen (U.S.N.M. Cat. No. 19076) from Albatross station D2144, in 896 fathoms (1,639 meters), in the Carib- bean. Specimens which may be referred to this variety occur at two different localities in the Albatross dredgings. There are three stations in the Caribbean, the remainder off the northeastern coast of the United States. Brady records Lagena laevis in this same general area from off the coast of Brazil, off the Virgin Islands, off Bermuda, and off the eastern coast of the United States. An ex- amination of some of the originals of these records may show that they belong to this variety. 30 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. Lagena laevis, var. nebulosa—material examined.

Description—Test flask-shaped, usually compressed, body oval or ovate, surrounded by a simple peripheral keel which has numerous radiating tubulations, neck usually comparatively short, in complete specimens usually joined with the peripheral keel. Length 0.4-1 mm. Distribution —Williamson originally described this as a variety of Lagena marginata. It has been recorded by numerous authors from about the British Isles, as the above list of references will show. The only station from which I have had specimens in the Albatross collections which might be referred to this species is D2150, in the Caribbean Sea. Specimens were few, but radiating tubulations were much fewer than in Lagena sublagenoides Cushman. There are numerous other records for this species in different parts of the oceans, but they are not always figured and described in detail, and it is probable that there are more than one species or variety involved.

Length 0.385-0.50 mm. Distribution—Most of the records for this variety are from the region of the British Isles and the Mediterranean. Although speci- mens referred to the typical form of the species have occurred in the Albatross dredgings, none of them showed the striations character- istic of this variety.

Soc., 1916, p. 44. Description—Test subglobular, or slightly pyriform, broadest toward the base, apertural end truncate, with an entosolenian neck, base often with a short projection; surface with very fine longi- tudinal markings, often indistinct; surface dull. Length up to 0.25 mm. Distribution—This species, originally described by Williamson, occurs at a large number of stations off the British Isles. The figures of specimens from other regions seem to show that they are not identical with the British specimens. I have failed to find any typical specimens except in the British material that I have had. This is from off Baltimore, southwest of Ireland, in 26 fathoms (48 meters). LAGENA LONGISPINA (H. B.

Description —Test. subglobular, or somewhat compressed; wall fairly thick; surface smooth, basal portion furnished with two or more long spines, Length without the spines up to nearly 1 mm.; spines often longer than the length of the test. Distribution—Brady figures several forms under this specific name, all of which are marked by elongate spines from the basal portion of the test. Flint’s figures from the Albatross collections show specimens very much like those I have figured here. So far as I have seen in the Albatross material from the western Atlantic, the specimens typically have two very long divergent spines, their centers hollow. Egger gives figures of this species but they are not at all FORAMINIFERA OF THE ATLANTIC OCEAN, 33 characteristic if they can be considered specifically identical with this species. It has not been recorded in all the work from about the British Isles and is evidently a species of comparatively deep water. It was found at a number of stations south of the latitude of New York, off the northeastern coast of the United States, one station in the northern part of the Gulf of Mexico, and one east of Trinidad. Caribbean. Flint’s specimens were from the Gulf of Mexico and the Brady’s stations are well scattered in the deeper water of various parts of the Atlantic and elsewhere.

Nearly all the records for this species are from the coasts of the British Isles and the Mediterranean, although Heron; Allen and Ear- land record it from the Kerimba Archipelago. It has not occurred on the western side of the Atlantic. LAGENA MALCOMSONII Wright. Plate 6, fig. 4. Lagena laevigata (Reuss), var. malcomsonii Wricut, Proc. Belfast Nat.

Heron-Allen and Earland give the following notes on this species from the Clare Island Survey Report : A few specimens sparingly distributed over 11 stations. Wright’s species is merely L. quadrata (Williamson) in which the marginal edges are rounded FORAMINIFERA OF THE ATLANTIC OCEAN. on instead of acute, and the aperture is surrounded by a produced lip. Specimens vary accordingly within all the limits usually found in L. quadrata. Wright’s figures represent a somewhat long shell with practically parallel sides. The range in shape among the Clare Island specimens extends from almost square tests to the outline of Wright’s figure, but we have met with specimens in Goldseeker dredgings in which the shell is very much longer and narrower, resembling, in fact, a piece of compressed tubing. They also record it from the west of Scotland and off South Corn- wall. It seems to be rare. I have had no specimens from the western Atlantic. LAGENA MARGINATA (Walker and Boys). Plate 6, fig. 9. There are many references to this species in the literature, but if they are examined it will be found that they vary greatly in their characters. The main characteristic seems to be the development of a keel of greater or less extent about a usually subspherical central chamber. If, however, the original figures of Walker and Boys are consulted, it will be found that their figures show a more or less compressed pyriform test, gradually tapering from the somewhat curved apertural end, with a very broad rounded basal portion, and instead of having a thin broad keel, have a rounded narrow marginal carina. Such specimens as this are common about the British Isles and should be taken as the typical form of this widely recorded species. I have not found typical material on the western side of the Atlantic. As there are so many forms quoted under this species, an examination of much of the material which has passed under this name should be made and the various forms discriminated.

London, ser. 2, vol. 11, 1916, p. 251; Journ. Roy. Micr. Soc., 1916, p. 46. Heron-Allen and Earland make the following notes on this va- riety : “An occasional specimen found at 6 different stations. Only a few present the characteristics of Wright’s variety in a strongly marked manner. When typical this is one of the most distinctive and in- teresting varieties we know. The highly convex surface on one side of the shell, strongly contrasted with the flat surface on the other, and the curious aperture situated under a little hood on one side— 36 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. always the flat side of the test—are features not to be overlooked. The shape of the hood varies considerably and in some cases almost attains the trumpet-lke character of the aperture of Z. Millettii, but, of course, on a very much smalier scale.” They also record it from the west of Scotland and off South Corn- wall, rare in both cases. Wright recorded it from off the southwest- ern coast of Ireland. LAGENA MARGINATA (Walker and Boys), var. SEMICARINATA Sidebottom. Plate 6, fig. 13.

Irish Aecad., vol. 31, pt. 64, 1913, p. 85, pl. 7, fig. 4. The only Atlantic record seems to be that of Heron-Allen and Earland, from whom the figure is copied as well as the following notes: “We have one specimen from Station 13 which we are inclined to attribute to Mr. Sidebottom’s variety in spite of certain essential differences. In the text of his paper he described the variety under the name of L. tnaequilateralis Wright var. semi-marginata (nov.), no doubt overlooking the fact’ that his varietal name had already been appropriated by Reuss. In the plate, however, this specimen is described as var. semi-carinata. Mr. Sidebottom’s specimen is de- scribed as ‘an interesting variation of Z. marginata var. inaequilat- eralis Wright. The mouth is the same as in Mr. Wright’s form, and the test is also inequilateral. The keel, however, is confined to the aboral end of the test and is well developed.’ “Our specimen differs, inasmuch as the aperture is fissurine, and the shell is of the normal equally biconvex type, with an attached en- tosolenian tube. The marginal keel, however, exactly resembles Mr. Sidebottom’s figure in position and extent.” LAGENA MARGINATA (Walker and Boys), var. SEMIMARGINATA Reuss. Plate 6, figs. 14, 15. The only Atlantic records for this species are given by Brady,°® off Prince Edwards Island, 50-150 fathoms (91-274 meters), off Heard Island, 75 fathoms (137 meters), and three stations in the middle of the South Atlantic, 1,900, 2,200 and 2,350 fathoms (3,475, 4,024, and 4,298 meters).

There is considerable variety in the specimens, some having a single keel, the true L. marginato-perforata, others a double keel (= Fissurina punctate (Seguenza)); while many of the specimens are ornamented with a varying number of minute radiating costae at the two extremities of the shell, which, however, are not produced over the central area of the test. There is usually an attached entosolenian tube, and the coarse perforations from which the species takes its name are gen- erally suppressed in the area of the shell where the tube is attached. This agrees with Mr. Sidebottom’s specimen and drawing; but in his specimens the internal tube is described as being straight and free. The species is of fairly common occurrence in shallow-water tropical gatherings. Mr. Wright has recently described and figured 38 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. it under the name ZL. laevigata var. marginato-perforata, as a fossil from the Estuarine Clays of Magheramorne, ‘ very common,’ recent Irish specimens ‘ very few.’” The above notes are from Heron-Allen and Earland on their specimens from the Clare Island region. They also record it from the west of Scotland and off South Cornwall, but rare. I have found no specimens that I could refer to it in the western Atlantic material. LAGENA MELO (D’Orbigny).

Length up to 0.25 mm. Distribution—Specimens which can be referred to this species were obtained at a few Albatross stations. There are a few records for it from the western Atlantic, those of Brady, Parker, and Jones from off the Abrohlos Bank, and it has been recorded from the Gulf of St. Lawrence, Gaspé Bay, and off Labrador, and off the banks of Newfoundland. There are a few records for it about the British Isles, but it seems to be less common there than are the other reticulately ornamented forms. The Albatross specimens are from the north- eastern coast of the United States, with one station off Cape Hat- teras and one off the southern part of Florida. Lagena melo—material examined.

The following notes are from Heron-Allen and Ear- land on their Clare Island specimens, which are here figured. “An occasional specimen at six stations, varying as usual consid- erably in size and contour. “The exact nature of this curious variety is extremely doubtful. In the ordinary course such distorted specimens would be regarded as ‘sports’ and set aside; but the general uniformity of their nature, and their wide distribution, coupled with the fact that no other species of Zagena presents similar characteristics, make it certain that some zoological significance is attachable to their occurrence. Possibly they represent some stage in the life-history of the species with which we are at present unfamiliar. “We have no data to add to the information already furnished by Mr. Wright. The most characteristic Clare Island specimens cor- respond exactly with Alcock’s original description of the compressed form ‘resembling a dried fig.’ ” LAGENA MILLETTII Chaster. Plate 7, fig. 5.

London, ser. 2, vol. 11, 1916, p. 253; Journ. Roy. Micr. Soc., 1916, p. 46. Description.—Vest compressed, inflated in the middle, the central body portion of the test nearly circular, apertural end slightly ex- tended, periphery with a thin keel running entirely about the test, at either side of which is a secondary lateral keel, slightly raised above the general surface; wall smooth, finely punctate, test with an entosolenian neck. Length not exceeding 0.40 mm. Distribution —I have had numerous specimens from off the Brit- ish Isles which are of this typical form figured by Williamson and in that region it is one of the common species. Although there are numerous records for the species elsewhere, the figures given show that the typical form was not that figured by the authors from other regions. I have failed to find any typical material in the western Atlantic, but the species is represented there by numerous varieties. This short, nearly circular form figured by Williamson may be taken as the typical form of the species. It is most simply charac- terized by the peripheral keel and the secondary keel on either side, dividing the test into two distinct portions on either side, that of the central part of the test inside the ring formed by the sec- ondary keel and the concave area extended around the test between the peripheral and the secondary keels. These two areas become variously ornamented and changed in their relation to one another, but these changes seem to be rather constant and show definite geo- graphical limits in their distribution. LAGENA ORBIGNYANA (Seguenza), var. ANTILLEA, new variety. Plate 7, figs. 10, 11. Description.—V ariety differing from the typical in the very large size, in the ornamentation, which consists of tubular radiate mark- ings in the peripheral keel, the secondary keel marked by a series of pits which extend in on to the body of the test itself, and extend up both sides of the apertural neck, nearly to the aperture itself; wall very thick, opaque. FORAMINIPERA OF THE ATLANTIC OCEAN. 41 Length slightly exceeding 1 mm. Distribution.—Type-specimen (U.S.N.M. Cat. No. 19107) from Albatross station D2355, in 399 fathoms (730 meters), in the Carib- bean, off Yucatan. This variety is somewhat similar to var. Jacunata (Burrows and Holland), but differs in the distribution of the pits and in the more elaborate ornamentation. Its very thick walls, large size, together with the peculiar ornamentation, will distinguish it from other varieties of the species. It seems to be limited to the western tropical Atlantic.

Plate 8, fig. 5. There are records for this form from the Atlantic about the British Isles as follows: Balkwill and Millett;* H. B. Brady;° Wright; ? Ballkwill and Millett; *t and Heron-Allen and Farland.” The British specimens do not seem to be typical of the form de- scribed by Brady, whose typical specimens were from the Indo- Pacific.

ELLIPTICA, new variety. Plate 6, figs. 10-12. Description.—Variety differing from the typical in the elongate pyriform shape, the central body portion of the test being elliptical, peripheral, and lateral keels sharp, thin, translucent, body of the test transparent, thin, made slightly granular by the punctae, the area between the keels and bordering the inner margin on the secondary keel usually opaque.

FORAMINIFERA OF THE ATLANTIC OCEAN. 45 Description.—Test elongate, elliptical in front view, nearly circu- lar in cross section, slightly compressed, ends broadly rounded, nearly equal; wall thin, transparent, smooth; aperture broadly ellip- tical, central, with a comparatively short entosolenian neck. Length 0.40 mm. Distribution.—Brady had this species from Challenger station 5 in the deep part of the North Atlantic, in 2,740 fathoms (5,011 meters). Egger records it from off West Africa and Heron-Allen and Earland record a single typical specimen from Killary Bay, Ire- land, and two specimens from off the west of Scotland.

Description.—Test flask-shaped, elongate, the basal end broadly rounded and the greatest width near the base, thence tapering gradu- ally to the apical end, which is furnished with a short, cylindrical, slender neck with a slight phialine lip, the base of the neck rather abruptly joined with the test; wall of the test compound, the outer surface longitudinally costate, with fine crossbars between them, the inner layer more or less spinose connecting it with the surface wall, wall opaque. Length up to 0.20 mm. Distribution.—Sidebottom originally described this form from the Southwest Pacific. I have specimens from four A/batross stations which are very similar to those described and figured by Sidebottom. ‘They are not as long nor quite so tapering as his specimens and the costae not so pronounced. They have a similar compound wall, and the general manner in which the neck is attached to the body of the test is also strikingly similar. It seems worthy of specific rank.

Lagena vulgaris WILLIAMSON, var. perlucida WILLIAMSON, Rec. Foram. Great Britain, 1858, p. 5, pl. 4, figs. 7, 8. Description—TYest somewhat pyriform, elongate, widest near the base, the apertural end continued into an elongate cylindr:cal slender neck, with a slight lip, the opposite portion of the test with a few fine longitudinal costae, extended part way up the body of the test; surface otherwise smooth. Length up to 0.25 mm. Distribution.—All the records for this species seem to be from about the British Isles, except that of Heron-Allen and Earland, who record it as “ few and poor” from the Kerimba Archipelago, off the southeastern coast of Africa. The only specimens I have had were from Dog’s Bay, Ireland, and from 10 miles off Glencoe, southwest of Ireland, in 53 fathoms (97 meters), both from material received from Mr. Joseph Wright.

Mr. Sidebottom quotes a letter from the late Dr. Chaster supplementing his original description of the species, and replying to various criti- cisms to which the species had been subjected. In our opinion, this form remains one of the most unsatisfactory with regard to its affinities. There is little doubt that many of the specimens have originally been sessile, a habit which is otherwise unknown in the genus Lagena. Moreover, traces of apparent segmentation are not uncommon, which in itself would remove the species from the genus Lagena to Polymorphina. But the quantity of available material is not at present sufficient for final settlement of this question, and FORAMINIFERA OF THE ATLANTIC OCEAN. 47 for the present we prefer to leave the species in the position to which Dr. Chaster assigned it, and in which Mr. Sidebottom, who has had wider opportunities of judging than ourselves, concurs. It may be observed that Messrs. Jones and Chapman include this species among their type-species of Ramulina.” The above notes are from Heron-Allen and Farland. The only Atlantic records for this species seem to be those of Chaster and Heron-Allen and Earland from about the British Isles. LAGENA PULCHELLA H. B. Brady. Plate 9, fig. 3. Lagena pulchella H. B.

Distribution.—This species was originally described from off the British Isles by Williamson. It has since been recorded from about the British Isles by several authors. There are numerous records for its distribution elsewhere. but from the specimens I have seen from the western Atlantic and other regions the typical form is best seen in the eastern North Atlantic.

Description.—‘ Test pyriform and more or less compressed, the margin obtuse or rounded, the base frequently mucronate, and the aperture entosolenian; the surface bears four arched costae, two on each face of the test, near the lateral margins and parallel to them. The costae are thickest near the middle and taper away toward the ends.” Length 0.25 mm. Distribution—The Atlantic records for this species consist of a questionable one of Pearcey as very rare in the Faroe Channel, and from the Summary of Results of the Challenger Expedition, it is recorded from station 13, in the North Atlantic, 1,900 fathoms (3,475 meters). Wright records it as common, with trigonal forms rare, from Dog’s Bay, Ireland, and Earland records it from shore sands at Bognor, Sussex, rare. Pearcey records it from Burdwood Bank, in the South Atlantic, 56 fathoms (102 meters), and one deeper station, in 1,998 fathoms (3,654 meters).

Length up to 0.30 mm. Distribution.—I have had no specimens from the western Atlantic which seem to be this species, nor is it recorded from the region south of the Gulf of St. Lawrence. There are records for it off Labrador, in Gaspé Bay, in the Gulf of St. Lawrence. It is very numerous about the British Isles, as the long list of references shows, and there are a few other records for it elsewhere. Cat. No. Coll.

Length up to 0.380 mim. Distribution —Specimens of this type were originally described from about the British Isles, and have been referred to by many au- thors as the above synonymy will show. It is very evident from an examination of the various figures given that numerous forms of or- namentation have been included under this name. I have failed to find any specimens from the Albatross material from the western At- lantic which can be referred to this, but I have very typical specimens from off the British Isles. Whether the specimens from remote parts of the world which have been referred to this species are identical is very questionable. Lagena squamosa—material examined. Bot- Depth | No. of : tom | Cat.)

FORAMINIFERA OF THE ATLANTIC OCEAN. 53 Description.—Test ovate, compressed, wall smooth, periphery usually keeled, with several spines symmetrically arranged about the border; aperture fissurine. Length about 0.50 mm. Distribution.—There are very few Atlantic records for this species. There is a single Challenger station from the middle Atlantic which is south of the Equator, one Gazelle station recorded by Egger from off West Africa, one Albatross station recorded by Flint in the Carib- bean, off Panama, and Pearcey records it from the far South Atlantic in deep water. I have a single specimen which can be referred to this species from Albatross station D2174, off the eastern coast of the United States in deep water. The species was originally described from the late Tertiary of Kar Nicobar. As the few records show, it has been recorded from many widely separated regions. Except for the records of Wright in deep water off the southwestern coast of Ireland, there seem to be no records from the region of the British Isles.

Brady’s Challenger stations included both the North and South Atlantic, but mostly in deep water. Pearcey records this species with a question from the Faroe Channel, and Earland a single speci- men from shore-sand at Bognor, Sussex. I have failed to find any material in the western Atlantic referable to this species. 54 BULLETIN 104, UNITED STATES NATIONAL MUSEUM, LAGENA STEWARTIL J. Wright. Plate 10, fig. 7. Lagena stewartii J.

FORAMINIFERA OF THE ATLANTIC OCEAN. 55 Description—Test flask-shaped, nearly circular in cross section, body of test subglobular, neck variable in length, usually rather abruptly contracted from the body of the test at its base; surface ornamented with numerous rather fine costae running the entire length of the test, apical end typically broadly rounded, occasionally slightly tapering to a point. Length 0.25-0.75 mm. Distribution—From the list of references it would seem that this is a very widely distributed species. There are numerous records for it about the British Isles and a few others from various parts of the Atlantic, as well as in other regions. However, all the striate Lagenae I have had from the western Atlantic seem to be better placed under other species. LAGENA STRIATO-PUNCTATA Parker and Jones. Plate 10, fig. 10.

It is decorated externally with tolerably stout longitudinal costae, from 6 to 20 in number, bearing conspicuous pseudopodial foramina. The perforations are placed either in single rows down the middle of the costae or in double lines, one on each side, in their thickened bases.” Length 0.30—-0.50 mm. Distribution.—There are numerous records for this species off the British Isles and in other parts of the Atlantic, off Spitzbergen, 56148—23——_5 56 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. off the Canary Islands, and from the Gulf of St. Lawrence.

Description.—Test flask-shaped, much compressed, central body of the test elongate-ovate, tapering into a long, slender neck, sur- rounded by a wide peripheral keel with numerous close-set, fine tubulations, central portion smooth, apical end of keel usually but not always emarginate. Length 0.60-0.85 mm. Distribution—I\ have previously recorded this species from the Pacific, off the Galapagos Islands and near Midway Island in fairly deep water. In the Aébatross Atlantic collections it occurred at three stations, two in the northern part of the Gulf of Mexico, and one in the western Caribbean. At the last station there is a tri- hedral specimen, but in its general characters like the typical. It seems to be different from Lagena lagenoides (Williamson), as I have previously shown, especially by its very numerous close-set tubulations and usually with a long slender neck. The specimen figured here is somewhat broken.

No. 18881) from Albatross station D2203, in 705 fathoms (1,289 meters), off the northeastern coast of the United States. This species is abundant at numerous stations off the northeastern coast of the United States. It is evidently the same as that figured by Parker and Jones as Marginulina litwus from the Arctic in 160 fathoms (293 meters), at Nordland, Norway. Flint’s specimens were from this same gen- eral region, and it is evidently a species which ranges south, perhaps to the latitude of Cape Hatteras, and in its northern distribution reaches to the Arctic Circle.

Cristellaria aculeata D’OrBIGNY, var. marginulinoides Gois, Bull. Mus. Comp. Zo6l., vol. 29, 1896, p. 56, pl. 5, figs. 15, 16. Description —Test elongate, much compressed, the early portion close coiled, the later chambers uncoiled and becoming more inflated, periphery slightly keeled in the early portion, with or without spines; sutures marked by a series of fine beadlike processes, slightly elongate across the sutures; sutures in the later portion depressed, somewhat limbate, not beaded, general surface between the sutures of the early portion somewhat spinose, later smooth, apertural face rounded, not truncate; aperture becoming terminal, slightly pro- jecting, small, radiate. Length of Albatross specimens slightly exceeding 1 mm.; as given by Goés, up to 2.50 mm. Distribution —I have had specimens from two Albatross stations, one in the northern part of the Gulf of Mexico, the other off the coast of Georgia. These differ somewhat from Goés’s originals in having very little trace of the spines on the margin, but they have the characteristic sutural ornamentation and the rounded later por- tion of the test, in these characters differmg from Cristellaria subaculeata, var. glabrata.

FORAMINIFERA OF THE ATLANTIC OCEAN. io Distribution—The type specimens of this species described by Flint were from A/batross stations in the northern part of the Gulf of Mexico in 196 and 210 fathoms (359 and 384 meters). I have had material from this same region and from two other stations, one off the southern tip of Florida, the other off the coast of Georgia. This is a common range for numerous species. In some ways the species resembles the young of Vaginulina spinigera, but the specimens are always small and more Cristellaria- like in every way. , Cristellaria linbata—material exanvined. of Depth] fiom No. tom Cat. | Con. of— | speci-| Station.

Description—Test slightly longer than broad, somewhat com- pressed, periphery with a narrow thin keel, test becoming slightly uncoiled in the later portion; chambers comparatively few, about 8 in the last-formed coil, distinct, but not inflated; sutures marked by lines of raised bead-like prominences, the surface of the test between with finer more spinose projections, apertural face truncate, smooth, the sides with a raised keel; aperture projecting, rather broad, radiate, at the peripheral angle of the last-formed chamber.

Brady gives two records for this species—off Culebra Island, 390 fathoms (713 meters), and off Sombrero Island, 450 fathoms (823 meters). The only specimen I have had which is identical with Brady’s is from the type station. This has the typical surface ornamentation as figured by Brady and seems distinct from the following variety. The species seems to be limited to the tropical western Atlantic. However, Earland ® records one small and immature specimen and one large shell from Bognor, Sussex, England. 68 Journ. Quekett Micr.

Length of Albatross Atlantic specimens 3.50 mm. Distribution—The Atlantic records for this species are given by Brady off Sombrero and Culebra Islands, West Indies, off Bermuda, and off the coast of Spain. It is recorded by Goés from the Carib- bean and the Gulf of Mexico, 169-658 fathoms (808-1,203 meters). He records specimens attaining the length of 8 mm. Flint had speci- mens from the Gulf of Mexico and off the coast of Georgia, 196 and 440 fathoms (359 and 805 meters). I have had specimens from four Albatross stations, two stations in the Gulf of Mexico, one of which is the same as that from which Flint records the species, one off the northern coast of Cuba, and one off the South Carolina coast. From the British Isles it is recorded from the Estuary of the Dee, a single specimen off the southwest of Ireland, at 345 fathoms (631 meters) (Wright) ; and off South Cornwall (Heron-Allen and Ear- land). It occurs in the Miocene of the Bowden marl of Jamaica as fairly large specimens, and is known from numerous records in the Indo-Pacific, often reaching a large size at moderate depths in tropical waters. 126 BULLETIN 104, UNITED STATES NATIONAL MUSEUM.

Description—tTest elongate, generally triangular in transverse section; chambers comparatively few, periphery carinate; sutures distinct, curved, very slightly if at all depressed; apertural face of the last-formed chamber truncate, reaching from the apertural end of the test nearly to the initial end; wall smooth; aperture radiate, terminal. Length up to 1.50 mm. Distribution—Brady described this species from two Challenger stations, one off the western coast of New Zealand, 275 fathoms (503 meters), and the other in the Atlantic, off Culebra Island, West Indies, 390 fathoms (713 meters). Apparently the only other At- lantic records are those given by Flint, off Careysfort Light, off Southern Florida, in 60 fathoms (110 meters), and Albatross sta- tion D2377, in the northern part of the Gulf of Mexico, in 210 fathoms (3884 meters). The other records are from the Indo-Pacific, especially the area of Australa and New Zealand, with a few records which I have given from the Philippines. I have had Atlantic speci- mens from three stations, one in the northern part of the Gulf of Mexico and two off the eastern coast of the United States. In the Summary of Results of the Challenger Expedition the species is recorded off Bermuda. Therefore there are either two or more species, one in the western Atlantic, the other in the Indo-Pacifle, or else a single widely spread species covering these two regions.

Description—Test subcylindrical, early portion close-coiled, later chambers uncoiled, rounded in transverse section, the last-formed chambers often inflated; aperture in early chambers marginal, later often becoming nearly median, usually radiate. It is a question whether the species placed under this genus might not be included under the uncoiled Cristellarias. In general the chambers of the uncoiled portion in Marginulina are nearly circular in transverse section and the ornamentation is usually limited to longitudinal costae. Its geological history goes back, as does that of Cristellaria and Nodosaria, to the Cambrian. MARGINULINA GLABRA D’Orbigny. Plate 36, figs. 5, 6. Marginulina glabra D’OrsIeNy, Ann. Sci.

Length up to 2 mm. Distribution.—This typical form of the species is recorded at numerous stations about the British Isles. There are numerous other records for it in the Atlantic, and numerous authors have re- ferred to it specimens from various parts of the world. The only figures are those given by Balkwill and Wright, and they show a more nearly typical, more slender form than that found on the western side of the Atlantic which is here referred to the following variety. MARGINULINA GLABRA D’Orbigny, var. OBESA, new variety. Plate 37, fig. 1. Marginulina glabra Furint (not D’Orbigny), Rep. U. S. Nat. Mus., 1897 (1899), p. 188, pl. 60, fig. 1 (in part). Description.—V ariety differing from the typical in the larger size and much shorter, broader form. Length up to 3 mm. Distribution—Type-specimen (U.S.N.M. Cat. No. 17489) from Albatross station D2043, in 1467 fathoms (2683 meters), off the northeastern coast of the United States. This larger, stouter form which may be referred to D’Orbigny’s species as a variety, is very common at numerous stations around latitude 40 and longtiude 70, southwest of the New England coast, and runs south at occasional stations about the Gulf of Mexico and the Caribbean. Flint’s sta- tions for the species were mostly in this same region, and Brady records J. glabra from a Challenger station off New York where he presumably had this same large form. There are numerous other scattered records for the species in the Challenger report, and from off the coast of the British Isles, but specimens are not figured and it is very difficult to say just where they should belong without seeing the originals. In the microspheric form of the species there are a few chambers which show the coiling condition, but in the megalospheric form specimens occur which, except for their association with the micro- spheric form and their slightly oblique sutures, might be referred to Nodosaria.

Mus., 1897 (1899), p. 314, pl. 59, fig. 3. Description —Test much elongate, subcylindrical, only slightly ta- pering, often slightly curved, early portion somewhat compressed ; chambers close-coiled, later portion uncoiled, chambers inflated, dis- tinct, the ventral side somewhat lobulate, dorsal side much less so; sutures distinct, depressed; wall smooth, fairly thick; aperture ec- centric, at the dorsal angle somewhat projecting, radiate. Length 2.50-4 mm. Distribution—This species was originally described by Bailey from numerous stations southeast of Montauk Point, New York, to southeast of Cape Henlopen where, he says, “ This fine species is one of the largest and most conspicuous forms in these soundings.” Flint’s specimens were from three Albatross stations, one off the Atlantic coast and about the latitude of New York, another off Cape Hatteras, and the third in the Gulf of Mexico, depths ranging from 58-160 fathoms (106-293 meters). The first two of these stations are in the area where this species occurs very abundantly. In the Albatross material that I have examined this species has been very 130 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. abundant at several stations from about the latitude of Cape Cod, southward to the coast of Carolina, with a few specimens off Florida. It sometimes occurs in very considerable numbers and usually at moderate depths. In reviewing the literature the species does not seem to have been recorded in any recognizable form outside this general area. The figures given by Bailey, while somewhat crude, show very well the general character of this species, and his designation of its occurrence, together with the very adequate description, make no question about referring these specimens from our Atlantic coast to his species.

Cristellaria ensiformis Gots, Bull. Mus. Comp. Zo6l., vol. 29, 1896, p. 57, pl. 5, figs. 17, 18. Description.—V ariety differing from the typical in the somewhat smaller size and the development of numerous acicular spines about the early coiled portion. Distribution—Goés described this species from the Caribbean Sea in 196-210 fathoms (359-384 meters). I have had this variety from but one station in the material of the Albatross dredgings, which I have studied. This is from off the southern coast of Florida. It is to be suspected that the one station given by Flint from the northern part of the Gulf of Mexico for Marginulina ensis may be this variety. This variety evidently replaces the typical form in warmer waters. FORAMINIFERA OF THE ATLANTIC OCEAN. tad Marginulina bacheti, var. ensiformis—naterial examined. Bot- Depth | No. of : tom Gt.

Mus., vol. 4, 1921, p. 255, pl. 41, fig. 2. Description—tTest elongate, early part forming a portion of a coil, later chambers moniliform, tumid, separated by deep constric- tions; wall typically with numerous very fine longitudinal striae; aperture at the end of a well-developed neck, eccentric on the dorsal side, radiate. Length nearly 2 mm. Distribution originally described this species from a single Nero station, 2071, in 271 fathoms (496 meters), off the Hawaiian Islands. I have since had it from three stations in the Philippine region, ranging in depth from 78-554 fathoms (143-1012 meters). I have specimens from the Gulf of Mexico and Caribbean Sea which may be referred to this species; the Atlantic stations range from 169-683 fathoms (309-1,248 meters), but the species is rare at all the stations. It has not hitherto been recorded in the Atlantic. This is another one of the examples of a species occurring in the Gulf of Mexico and Caribbean which has its range westward across the tropical Pacific. Marginulina striatula—material examined.

There is evidently a difference in that found off the British Isles and the species found in the West Indies of which I have but a single specimen. .

Description.—Test elongate; chambers in a linear series, placed so that the sutures are oblique; aperture marginal; chambers laterally compressed. The species of Vaginulina are undoubtedly derived from coiled forms, such as Cristellaria. Most of the fossil forms are compressed and very different from the recent species usually placed under this genus. The aperture usually is kept at the margin of the test, and the sutures oblique throughout. It reaches its greatest development in the Mesozoic. Its geological history evidently ranges from the Lias to the present time. FORAMINIFERA OF THE ATLANTIC OCEAN, foo VAGINULINA LEGUMEN (Linnaeus). Plate? 3, ties: Nautilus legumen Linnagus, Syst.

Length of the largest Atlantic specimen 1.25 mm. Distribution—This species has occurred at several stations along the eastern coast of the United States and at two stations in the northern part of the Gulf of Mexico. Brady records it from one station off New York and at several other stations, one west of the Azores, one south of the Canary Islands, and one in the middle of the South Atlantic. Flint recorded it from the northern part of the Gulf of Mexico. It is recorded by numerous authors off the coasts of the British Isles. There are many other records for this species outside the Atlantic as the above references show. 134 BULLETIN 104, UNITED STATES NATIONAL MUSEUM.

Length up to 4 mm. Distribution—Type-specimen (U.S.N.M. Cat. No. 17404) from Albatross station D2415, in 440 fathoms (805 meters), off the coast of northern Florida. This is evidently the species described and figured by Flint as V. linearis. It is probably also the same as the Chai- lenger material referred by Brady to V. linearis, but who mentions that “the specimens are few in number and are hardly ever typical as to minor characters.” The specimens were from off Bermuda, 435 fathoms (796 meters), off Culebra Island, 390 fathoms (718 meters), and off the coast of South America, southeast of Pernam- buco, 850 fathoms (640 meters). Flint’s specimens were from off the coast of Georgia and Florida, 87-276 fathoms (68-505 meters). Goés may have had this species from the Caribbean, mentioning one as “ only being perhaps more cylindric in the circumference ” than the typical. I have had specimens from several Albatross stations which are given in the accompanying table. They range from Florida along the eastern coast of the United States, the specimens being most abundant off the coast of Georgia, where they are also recorded by Flint. This species has a rounded base and is much more cylindrical than V. linearis. Vaginulina americana—mnaterial examined. | Bot- | Depth No. of : | tom ee Coll. of— | speci-| Station.

Description —tTest elongate, somewhat curved, initial end pointed with a short spine, whole test somewhat compressed; chambers com- paratively few, about 10 in a fully grown specimen, inflated, es- pecially toward the apertural end, earlier chambers more com- pressed; sutures distinct but only depressed toward the apertural end; surface ornamented by numerous somewhat oblique longitudinal lines, usually not extending out on to the last-formed chamber; aperture at the dorsal side, somewhat projecting, radiate. Length up to about 3 mm. Distribution.—This species described by Montagu from the shores of the British Isles seems to be restricted to the European side of the North Atlantic. It has been recorded by numerous authors from this general region. Its northernmost record is that of Parker and Jones from between Drontheim and North Cape. Some of the records given by Wright off the British Isles are as much as 50 fathoms (91 meters). In the Challenger report Brady mentions it from the Shetlands and Hebrides at depths of 15-90 fathoms (27- 165 meters) where it is common, and states that it also occurs off the coasts of Norway and France, but that the Challenger material 138 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. which he had from the western Atlantic was not typical. That ma- terial has been placed in the following species: VAGINULINA SPINIGERA H. B. Brady. Plate 37, figs. 6-8; pl. 38, fig. 1. Marginulina, species, WHITEAVES, Rep.

Description.—Test elongate, tapering, gradually increasing in di- ameter toward the apertural end, near the initial end are typically two long acicular spines, sometimes nearly half the length of the test itself, at widely divergent angles; chambers fairly numerous, the early ones coiled, the later ones uncoiled, oblique, the dorsal side higher than the ventral; sutures distinct, somewhat limbate, occasionally showing a slight tendency toward beading and the last- formed chambers sometimes depressed; aperture at the dorsal margin of the last-formed chamber, slightly projecting, radiate. Length without the spines up to 5 mm. Distribution.—This species was originally described by Whiteaves from the Gulf of St. Lawrence but he did not give it a specific name. M. Sars gave a name Marginulina spinosa in one of his lists from off the coast of Norway, but as no description or figure was given, the name has not been used. Brady described the species in 1881 and figured it in the Challenger report for the first time. The Challenger records are three—off the coast of South America, near Pernambuco, Brazil, 675 fathoms (1,284 meters), and from two in the Pacific, off Sydney, New South Wales, 410 fathoms (750 meters), and north of the Ki Islands, 580 fathoms (1,061 meters). Wright records the species as rare, off the southwest coast of Ireland, 1,000 fathoms (1,829 meters). Pearcey records a few from the warm area of the Faroe Channel. Flint recorded it from two stations off the northeastern coast of the United States in 328 and 430 fathoms (600 and 805 meters). Another record is that which I have given from off Bouro Island, at Albatross station D5637, in 700 fathoms (1,280 meters). This is not far from one of the Challenger stations. There is some variation in the spines developed at the base of the test. The typical form has two, usually widely divergent, but occasionally a third is developed, more nearly in the axis of the test—very rarely the spines themselves are bifurcate. In specimens which are evidently senescent there is a reduction in the width of the final chamber.

Description—Test compressed, in the adult consisting of cham- bers, elongate and narrow, running back on either side of the test; wall vitreous, finely perforate; aperture single, either radiate or surrounded with a lip which is usually cut in a radial manner; sur- face smooth or ornamented with costae; microspheric specimens with a coiled development in the earlier chambers; megalospheric specimens without the coiled chambers as a rule. The genus Frondicularia is evidently derived from a coiled an- cestry, such as Oristellaria. The microspheric forms invariably show coiled chambers in the young, and were formerly placed under the genus Flabellina. Megalospheric specimens of the same species often show typical adult characters appearing directly after the pro- loculum. Its geological history ranges from the Permian to the present. It is particularly abundant in the Cretaceous. At the present time large typical Frondicularia species are comparatively rare. There is a development of it in the warmer waters of the western Atlantic, and in tropical and subtropical waters of the Pacific at depths 140 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. of 100-500 fathoms (183-914 meters). Fvrondicularia advena is found in deeper waters and is rather widely distributed. There are ‘several species which have been referred to this genus in recent years which possibly should not be placed here. They are small, thin-walled species, described from the Mediterranean or the eastern, North Atlantic, in which there is a compressed form, but the typical inverted V-shaped chamber is not characteristically de- veloped. These species, moreover, instead of having the typical radiate aperture characteristic of Hrondicularia, more often have a small aperture, and it seems that they should be studied to see whether or not they really belong to this genus. FRONDICULARIA [?] TRANSLUCENS Heron-Allen and Earland. Plate 21, fig. 4. Frondicularia translucens Hrron-ALLEN and BARLAND, Proc. Roy. Irish Acad., vol. 31, pt. 64, 1913, p. 96, pl. 8, fig. 18. Description—* Test minute, ovate, compressed, rounded at both ends, and at the marginal edges, showing 3-4 chambers. The initial chamber large, inflated, lenticular in shape. Sutural lines somewhat obscure, especially in the later chambers. Shell walls transparent; surface minutely punctate; aperture a slit furnished with a curved entosolenian tube. “Length 0.14-0.16 mm.; breadth 0.10-0.12 mm.” Distribution—This species was described by the authors from Inishgoula Harbor, Ireland, in 14 fathoms. It seems questionable whether this should be referred to Frondi- cularia or not. FRONDICULARIA [?] SIDEBOTTOMI, new name. Plate 21, fig. 6. Frondicularia spathulata SipEsorrom (not Williamson), Mem. Proce. Man- chester Lit. Philos. Soc., vol. 51, 1907, p. 5, pl. 1, fig. 26—Hrron-ALLEN and EARLAND, Proc. Roy. Irish Acad., vol. 31, pt. 64, 1913, p. 97, pl. 8, fig. 12; Trans. Linn. Soc. London, ser. 2, vol. 11, 1916, p. 260. Description—Test minute, hyaline, compressed, periphery rounded, lobulate; chambers in a straight axis, increasing in breadth as added; sutures distinct, slightly depressed; wall smooth; aperture simple, elliptical, often with an entosolenian neck. Length of British specimens 0.20-0.35 mm. Distribution—Heron-Allen and Earland record this from five stations in the Clare Island region of Ireland in muddy localities. They also note its occurrence in the muddier dredgings from shallow water around the north and west coasts of Scotland and in the North Sea. Sidebottom figured the species from the coast of the Island of Delos. He referred to the same species a specimen FORAMINIFERA OF THE ATLANTIC OCEAN. 141 from the Bay of Palermo, but this has a different shape and an exserted neck and does not appear to be the same species. The name rondicularia spathulata was first used by Williamson for a species of a very different form from the British Coast which does not appear to have been since recorded. Brady used the same name for a species of a different form occurring in the Indo-Pacific which I have named /. bradyi Cushman. The specific name spathu- lata being preoccupied in this genus, [ have given the above name to the species of the Mediterranean and the coast of western Europe. FRONDICULARIA [?] PYGMAEA Sidebottom. Plate 21, fig. 3. Frondicularia pygmaea Sipesotrom, Mem. Proce. Manchester Lit. Philos. Soe., vol. 51, no. 9, 1907, p. 5, pl. 1, fig. 27.—Heron-ALLeEN and HAr- LAND, Proc. Roy. Irish Acad., vol. 31, pt. 64, 1913, p. 96, pl. 8, fig. 14. Description 'The initial chamber appears to be nearly globular, and the following ones are compressed, narrow and reflexed. The septa are arched, and slightly sunk, and the orifice is simple. A small wing commencing on the last chamber but one runs on either side of the test, gradually broadening out and terminating as a spine. The initial chamber is likewise armed with a small spine. Two specimens were found and both consist of five chambers.” Length of Delos figured specimen 0.20 mm.; off Clare Island specimen about 0.15 mm. Distribution.—Sidebottom originally described this species from the coast of the Island of Delos in the Mediterranean. Heron-Allen and Karland record it from the Clare Island region, off Ireland, and Earland had it from off Noss Head, Moray Firth. The microspheric form has a straight test without sign of coiling as does the megalospheric. It seems to belong rather to Lingulina than to Frondicularia. FRONDICULARIA ADVENA, new species.

Length 0.5-2 mm. Description—Type-specimen (U.S.N.M. Cat. No. 17526) from Albatross station D2205, in 1073 fathoms (1962 meters), off the northeastern coast of the United States. The only Challenger record for this species is off New York in 1,240 fathoms (2,268 meters). Flint has also recorded it in the same general area from two Alba- tross stations, D2530 and D2584, in 956 and 541 fathoms (1,748 and 989 meters). I have had it from numerous stations, most of them in the general latitude of New York, but one off Cape Hatteras, depths ranging from 168-1,362 fathoms (307-2,491 meters). There is a development of this species in the Indo-Pacific region, Brady giving the following Challenger stations: Near the Ki Islands at depths of 129 and 580 fathoms (236 and 1,061 meters) ; off Raine Island, Torres Strait, 155 fathoms (283 meters) ; and off the west coast of New Zealand, 275 fathoms (503 meters). He also gives another station off the Cape of Good Hope, 150 fathoms (274 meters). I have had what seems to be identical material from Albatross station D5123, east coast of Mindoro, Philippine Islands, in 283 fathoms (517 meters), and from D5652, in the Gulf of Boni, Philippine Islands, in 525 fathoms (927 meters). This therefore seems to be another one of those species which occurs at consider- able depths, both in the Western Atlantic and the Indo-Pacific. Heron-Allen and Farland have recorded a single imperfect specimen, fossil, from a clay which occurred in the shore sands of Selsey Bill. Sussex, England.” Bagg has recorded it as abundant from the Plio- cene at’ San Pedro, California,’? but his figures show very conclu- sively that it is an entirely different species from this. It is a small, delicate species, and very apt to be broken. Frondicularia advena—mnaterial examined. Bot- Depth No. of : tom vee Coll. of— | speci-| Station.

Length up to nearly 5 mm. Distribution.—This variety which is described by Vanden Broeck from off the Barbadoes in 84 fathoms (153 meters), is much more 144 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. common than the typical form. It has occurred at several stations in the Albatross collection from the Gulf of Mexico and off the Florida coast. Brady recorded this species from off Culebra Island, West Indies, 395 fathoms (721 meters), and from off Bermuda, 435 fathoms (796 meters). Flint has recorded it at 198 and 210 fathoms (363 and 384 meters), at stations D2399 and D2377, from both of which I have also had material. The records of Goés are from the Caribbean, 300-400 fathoms (549-732 meters). It seems therefore to be a species confined to the warmer portions of the western At- lantic and which is*developed at depths ranging from 100-400 fathoms (183-732 meters). The microspheric form of this species has the chambers arranged in a coiled fashion and in such specimens a much more pointed form is usually given to the base of the test. This is shown in some of the early figures given by Goés, and is here shown, plate 21, figure 1. This does not seem to be identical with the form named by D’Or- bigny, /rondicularia alata, from the Mediterranean. Frondicularia sagittula, var. lanceolata—material examined.

FORAMINIFERA OF THE ATLANTIC OCEAN, 145 FRONDICULARIA [?] TENERA (Bornemann). Plate 21, fig. 5. Under this name Heron-Allen and Earland record and figure ™* a single specimen from off the west coast of Scotland. There seems to be some doubt as to the exact origin of this specimen and whether it might have been a fossil or not. Subfamily 3. PotymorpeHrNinae. Test polythalamous; chambers usually arranged in an irregular spiral, in later growth sometimes approaching a biserial arrange- ment or sometimes uniserial; surface smooth or ornamented by spines or costae; aperture radiate. This subfamily includes the genus Polymorphina and its closely allied form Dimorphina. Genus POLYMORPHINA D’Orbigny, 1826. Polymorphina D’Orxsieny, Ann. Sci. Nat., vol. 7, 1826, p. 265.—H. B. Brapy, PARKER, and Jongs, Trans. Linn. Soc. London, vol. 27, 1870, p. 197, et seq.—H. B. Brapy, Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 557.—CHAPMAN, The Foraminifera, 1902, p. 199—CusHMAN, Bull. 71, U. S. Nat. Mus., pt. 3, 1918; p. 83. Description—Test more or less rounded, usually not equilateral; chambers few, obliquely placed in a more or less spiral arrange- ment; aperture terminal, radiate; wall calcareous, perforate, either smooth or variously ornamented with spines, costae, or tubercles. D’Orbigny divided this genus into several subgenera, none of which are at the present time recognized. The literature of this particular genus is more complicated than that of most of the genera, due largely to the fact that so many of the species have a smooth wall without ornamentation and specific characters have to be based almost entirely on the outline and arrangement of the chambers of the test. Allowing for the variation thought to occur in this and other groups of earlier authors, and the lack of close application of names in later work, the number of forms placed under almost any of the smooth species is very great. With the limited material at my disposal it is impossible to work out many of these complex cases. I have therefore thought it best simply to give the references under thé various names to the Atlantic records for the various species, and wait for the future to work out their real relations. That the species of Polymorphina are prob- ably as well characterized in their distribution as are other species of other genera may be shown by such well characterized species as Polymorphina myristiformis Williamson. This species, which has a peculiar ornamentation, occurs in considerable numbers in a very limited distribution about the British Isles and Western Europe, %* Trans, Linn. Soc. London, ser.,2, vol. 2, 1916, p. 260, pl. 42, figs. 8—10. 146 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. possibly also in the Mediterranean. It seems therefore that other species of this genus when their characters are clearly defined and plenty of material is available for examination, will be found to have distributions equally clearly delimited, as in the case of other species of the foraminifera.

The figure of Williamson may be taken as a typical western Euro- pean form of this species. Under this name in the literature are to be found a considerable collection of figures covering a variety of things not all of which certainly can be one species. Such forms as that figured by Williamson occur on the coast of the British Isles, and I have specimens of similar form from Iceland. On the western side of the Atlantic another form is common in shallow water especially off the New England coast. This is here described. i POLYMORPHINA LACTEA (Walker and Jacob), var.

Length up to 2 mm. FORAMINIFERA OF THE ATLANTIC OCEAN, 147 Distribution—Type-specimen from Cobscook Bay, near Eastport, Maine. I have had other specimens from off Trials Island, Eastport, and Casco Bay, Maine, shore sands from Coffins Beach, Annisquam, Massachusetts, and Newport, Rhode Island, and from the Woods Hole region, all on the New England coast. It has also occurred . in Gaspé Bay, 30-40 fathoms (55-73 meters). This variety ap- parently does not occur in the Albatross material of deeper water farther south. A specimen of a fistulose form is figured (plate 39, fig. 8) which may possibly belong to this species. It is from off the New England coast, Albatross station D2097.

There are many records from Eastern Europe referred to P. oblonga, Williamson’s form, which he described as P. lactea, var. oblonga, and which by several authors has been placed as a valid species. It is obvious that with D’Orbigny’s earlier name Williamson’s variety can not be used in a specific sense. * 56148—23——11 152 BULLETIN 104, UNITED STATES NATIONAL MUSEUM.

This name seems to be one commonly used for almost any form of smooth Polymorphina that has the chambers much inflated and projecting out from the general surface. Such forms are recorded — from many parts of the world, but do not seem to be present at least in the form figured by D’Orbigny from the western part of the Atlantic.

As the above list of references will show, however, the species has been recorded many times from the Eastern Atlantic, especially in the region of the British Isles. A reference to the few figures, however, will show what a diversity of form specimens referred to this species have. POLYMORPHINA CONCAVA Williamson. Plate 40, fig. 9.

FORAMINIFERA OF THE ATLANTIC OCEAN, 155 Description.—Test compressed, of few chambers, one side convex, the other nearly flat and expanded, apparently forming the attach- ment to the surface of some foreign body; surface smooth; sutures distinct, but very slightly if at all depressed; aperture radiate. Diameter of the main portion usually not more than 0.60 mm. Distribution.—This species was originally described from the coast of the British Isles by Williamson. Most of the records for it are from the same general region and in the Mediterranean. I have had what seems to be the same species from the Woods Hole region. POLYMORPHINA FLINTII, new species. Plate 40, fig. 10. Polymorphina compressa Fuint (not D’Orbigny), Rep. U. S. Nat. Mus., 1897 (1899), p. 319, pl. 67, fig. 3. Description.—Test oval or somewhat rhomboid, compressed ; cham- bers arranged in an irregular biserial manner, four or five chambers on each side in the adult, chambers somewhat inflated; sutures dis- tinct, but very slightly depressed; wall smooth and polished, thick; aperture terminal, radiate. Length up to 2.30 mm. Distribution—Type-specimen (U.S.N.M. Cat. No. 17691) from Albatross station D2415, in 440 fathoms (805 meters), off the coast of Georgia. Flint recorded this species as P. compressa from several stations off the southeastern coast of the United States, from Cape Hatteras southward. I have had specimens from Albatross stations from the region southward from Nantucket to the Florida coast. Brady records P. compressa from two stations in this general faunal area, one off Bermuda, and the other off the West Indies, which may probably belong here. So far as the material shows, this species has not occurred in either the Caribbean or the Gulf of Mexico. It is a large, well-characterized species in its more or less com- pressed form, somewhat alternating chambers, and thickened test. Polymorphina flintii—material examined.

Description—Test elongate, fusiform, outline not lobulate, initial end more or less pointed, apertural end produced into an elongate cylindrical neck; chambers few, slightly inflated; sutures fairly dis- tinct, but not depressed, except in the case of the last-formed one; wall more or less hispid, last chamber especially more inflated and more spinose. Length up to 0.60 mm. Distribution—Brady records this species from three stations in the North Atlantic, 1,125, 1,476, and 2,485 fathoms (2,057, 2,699, and 4,454 meters), and “the best examples of the species ” occurring in the South Atlantic at Challenger station 338, in 1,990 fathoms (3,640 meters). Therefore it seems probable that his figured specimens came from that station. He also gives four stations in the South Pacific, 1,875, 1,825, 2,075, and 2,425 fathoms (2,515, 3,338, 3,795, and 4,436 meters). Egger recorded a specimen from off Mauritius in 411 meters (225 fathoms). His figure is poor, and it may not be the same. Chapman records it from off Funafuti, 2,195-2,715 fathoms (4,010-4,965 meters). I had material from the North Pacific which I referred to this species, from off the Hawaiian Islands, in 1,670 fathoms (3,054 meters), and between Guam and Japan, in 1884 and 2,167 fathoms (3,446 and 3,963 meters). All the records for this species therefore are in deep water. The two Albatross stations in the Atlantic at which I have had specimens of this species, are in 1,362 and 1,395 fathoms (2,491 and 2,552 meters), agreeing with the previous findings in their general depths. These are off the north- eastern coast of the United States. Polymorphina extensa—material examined. Bot- Depth No. of 5 tom cat Coll. of— | speci-| Station.

FORAMINIFERA OF THE ATLANTIC OCEAN, 159 Description.—Test subglobular; chambers indistinct; sutures in- distinct, not depressed, surface ornamented with longitudinal costae, frequently broken into short sections; apertural end with a slightly projecting ring about the aperture. Length up to about 0.50 mm. Distribution—The species is common about the southern portion of the British Isles and more rare in the northern portion. Goés does not record it from the Scandinavian region, and it has not oc- curred in the western Atlantic collections I have examined. The only records outside the British Isles seem to be that of Sidebottom who had specimens referable to this species from off the Island of Delos in the Mediterranean, and of Williamson, who quotes “ Tene- dos (Levant).” The distribution of a striking species of this sort seems to show that the fauna of the southern coast at least of the British Isles is related to the Mediterranean, rather than to the western Atlantic. I have had excellent material from Europe and if its distribution included the western Atlantic, it would have surely been seen in the Albatross collections.

The only recent Atlantic records for this species are those given by Egger from western Africa and off the Cape Verde Islands. It is a species common in shallow water of the Indo-Pacific and has not occurred so far as I have seen where it might be most probably looked for, that is, in the tropical portion of the western Atlantic. Tt occurs as a fossil in the Tertiary of the Coastal Plain of the United States, and, according to Heron-Allen and Earland, fossil in England. POLYMORPHINA REGINA H. B. Brady, Parker, and Jones.

Description —tTest fusiform; chambers several, inflated, with deep sutures; wall ornamented with elongate, coarse costae, usually not broken on the individual chambers; aperture radiate, produced. Length not exceeding 0.75 mm. Distribution.—The only specimens I have had of this species from the Atlantic have been from the Tortugas region. It is recorded by Earland from Bognor, Sussex, England, a single specimen, and by Heron-Allen and Earland from shore sands of Selsey Bill, Sus- sex, England. Most of the records for the species are from the Indo-Pacific. I have found fossil specimens which seem to belong to this species from the Miocene and Oligocene of the Coastal Plain region of the southeastern United States. Subfamily 4. UVIGERININAE. Test composed of several chambers, typically spirally arranged, especially in the earlier portion, later chambers often becoming loosely arranged, or even uniserial; wall smooth or variously orna- mented; aperture typically consisting of a neck with a definite phialine lip. In Uvigerina the spirally arranged chambers are typical, old age characters appearing in the loss of ornamentation or in the tendency to become loosely spiral as in U. interrupta. In Siphogenerina the early chambers are spiral or biserial, especially well-developed in the micospheric form, and the later development is uniserial. * Genus UVIGERINA D’Orbigny, 1826. Uvigerina D’Ornieny (type, U. pigmea D’Orbigny), Ann. Sci. Nat., vol. 7, 1826, p. 268.—H. B. Brapy, Rep. Voy.

Description.—Test elongate, spiral, consisting of numerous cham- bers, usually arranged triserially, occasionally in later growth with fewer than three chambers in each volution; wall calcareous, per- forate, hyaline, smooth or ornamented with spines or costae or mod- ifications of them; aperture with usually a tubular neck at the end of which is a phialine lip. The genus Uvigerina and its related genus Siphogenerina form a very distinctive group. The triserial arrangement of the chambers FORAMINIFERA OF THE ATLANTIC OCEAN, 161 with a tubular aperture and phialine lip will at once distinguish Uvigerina from any other of the foraminifera. The ornamentation usually consists either of longitudinal costae which may be more or less interrupted or broken, or of spines. There is often a secondary type of ornamentation developed, as in U/. aculeata D’Orbigny where the early condition of the test is longitudinally costate, but in the adult a secondary wall is progressively laid down, finally covering the entire test, the surface of which is ornamented by coarse spines. Senescent characters appear most usually as a loss of ornamentation, or in the placing of the chambers at a distance from one another, as in U. interrupta H. B. Brady. Geologically the genus does not seem to occur farther back than the beginning of the Tertiary. From a study of the western Atlantic material and of the fossil collections from the Coastal Plain of the United States, it seems that the number of species of Uvigerina is much greater than has been recognized. In the western Atlantic they certainly have a very definite distribution and the characters are very constant. Likewise in the fossil series species seem to be rather limited in their vertical range.

Description—Test elongate, made up of numerous chambers, spirally arranged, three chambers making up each whorl; chambers inflated, rotund, distinctly separated externally by rather deep sutures; wall smooth, occasionally the early chambers showing traces of costae or spines; aperture usually with a tubular neck and broad phialine lip; color grayish-white. Length 1 mm. or somewhat more. Distribution—D’Orbigny originally described this species from the Canaries (shore sand of Teneriffe), and referred to it certain forms he had previously found in the Mediterranean. In the Chal- lenger collections Brady records it off Bermuda, 435 fathoms (796 meters), from the South Atlantic, off Buenos Aires, 1,900 fathoms 162 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. (3,475 meters), and off the Cape of Good Hope, 150 fathoms (274 meters). He also gives records from the Pacific. It occurs rarely about the British Isles, off Holy Island (Brady) ; estuary of the Dee (Siddall) ; southwest of Ireland (Wright) ; off Bognor, Sussex (Ear- land) ; Clare Island region of Ireland (Heron-Allen and Earland). Goés recorded it from off the Azores, and Egger, in the Atlantic, from off the Cape Verde Islands. There are numerous records for its occurrence elsewhere but they are not included here. On the western side of the Atlantic the only records are those of Brady. I have had no smooth Uvigerinae from the Albatross col- lections, nor did Flint. UVIGERINA AMPULLACEA H. B. Brady.

Mus., 1897 (1899), p. 320, pl. 68, fig. 5. Description.—Test composed of a group of chambers, making a test broadly rounded at the base and with an oval form, compact, followed by one or two chambers somewhat detached from the gen- eral mass; sutures slightly depressed; wall finely spinose, the apertural end of the last-formed chamber somewhat drawn out into a tapering neck, with a slightly phialine lip. Length slightly less than 1 mm. Distribution—Brady described this species as a variety of U. asperula Czjzek. His records in the Challenger report include in the Atlantic a station to the south of Ireland in 725 fathoms (1,326 meters) ; off Culebra Island, West Indies, 390 fathoms (713 meters), and off the coast of South America in 350-675 fathoms (640-1,234 meters). He also gives stations in the South Pacific 410-620 fathoms (750-1,184 meters). Flint’s specimens were from off the coast of Brazil. I have had specimens referable to this species from the Gulf of Mexico, the Caribbean, and off the coast of Brazil. It is recorded from other parts of the world, especially in the Pacific where it may occur. Uvigerina ampullacea—material eramined. Bot- : Depth No. of : tom Get: Coll. of— | speci-| Station.

Uvigerina auberiana D’OrBIaNy, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, 1839, ‘‘ Foraminiféres,” p. 106, pl. 2, figs. 23, 24. Description.—Test elongate, rapidly tapering from the narrow base to the greatest breadth somewhat above the middle; periphery lobulate; chambers inflated; sutures depressed, distinct; wall orna- mented, closely set with fine spinose projections; the last-formed chamber somewhat smoother and of lessened diameter; apertural end tapering, with an elongate neck which is spinose, ending in a phialine lip. Length up to 1 mm. Distribution.—D’Orbigny described this species from shore sands of Cuba, Jamaica, and Martinique. Brady records it from south of Rockall Bank in 630 fathoms (1,152 meters). His figure, however, is not like the typical form of the species as developed in the West Indies. I have specimens which may be referred to this species from stations off the coast of the Lesser Antilles. It is probable that the material from Abrohlos Bank off Brazil, of Brady, Parker, and Jones” is this species, the smoother form (fig. 5) possibly var. laevis Goés.

The only Atlantic records referred to this species are as follows: East of Buenos Aires, 1,900 fathoms (3,475 meters) (H. B. Brady) ; and off the southwest coast of Ireland, 1,000 and 1,020 fathoms (1,829 and 1,866 meters) (Wright). From the collections I have examined such forms as those figured by Brady have been seen only from the Indo-Pacific. Wright’s re- mark of his specimens that “ many of the specimens are intermediate between U/. aculeata and U. pygmaea” would probably indicate that he had the species I have in this paper named U. peregrina. UVIGERINA SEMICOSTATA, new species. Plate 42, figs. 1, 2. Description.—Test elongate, tapering, greatest breadth near the apertural end, initial end broadly rounded; chambers numerous, much inflated ; sutures distinct and much depressed ; wall ornamented in the adult with numerous short, low, rounded costae, beginning near the base of the chamber and extending up part of the way on its surface, the upper part of the chamber smooth and unorna- mented; aperture circular at the end of a short cylindrical neck with a phialine lip. Length up to 0.70 mm. Distribution.—Type-specimens (U.S.N.M. Cat. No. 17642) from Albatross station D2160, in 167 fathoms (305 meters), on the south- western coast of Cuba.

Mus., 1897 (1899), p. 320, pl. 68, fig. 1. Description.—Test somewhat elongate, not more than twice as long as broad, fusiform or oval; chambers rather obscure; sutures only slightly depressed and partially hidden by the ornamentation of the surface which consists of numerous very fine longitudinal costae only slightly raised above the general surface, the whole test thin and translucent, shining; apertural end slightly depressed, the apertural neck with its base in this hollow, the outer end with a flaring lp, the sides of the neck with two or three ringlike projec- tions. Length up to 0.65 mm. Distribution—Type-specimen (U.S.N.M. Cat. No. 17639) from Albatross stations D2641, in 60 fathoms (110 meters), off Carysfort Light, Florida. It also occurred in typical form at other stations about southern Florida, one off the coast of Georgia and one in the Caribbean Sea off Yucatan. This is a very distinctive species and is evidently limited to the warmer portions of the western Atlantic, unless, as is the case of other species, it may extend westward into the Indo-Pacific. The whole appearance is distinctive, in the very slightly lobulate outline, the sunken neck, the plates of the outside of the neck, the shining, translucent character of the test, and the fine ornament- tation. Flint has this species from this same station and referred it to U. tenuistriata Reuss. This is probably the species Goés figures and refers to U. pygmaea."® Uvigerina flintii—material examined.

The types were fossils from the region of Sienna, Italy. Except for the species here named U. peregrina, costate Uvigerinae from the Western Atlantic are very rare. I have scattered specimens from a few stations, none of which can be specifically identical with that of D’Orbigny. After reviewing specimens of costate forms from various parts of the present ocean and from the Tertiary, I am convinced that there are several distinct forms with definite distribu- tions that have all been included at various times under this name of D’Orbigny. UVIGERINA PEREGRINA, new species. Plate 42, figs. 7-10. Uvigerina pygmaea FLINT (not U. pigmea D’Orbigny), Rep. U. S. Nat. Mus., 1897 (1899), p. 320, pl. 68, fig. 2. Description.—Test elongate, about 24 times as long as broad, widest in the middle, ends rounded; chambers fairly numerous, in- flated, distinct; sutures depressed but the line of the suture in- distinct; wall ornamented with longitudinal costae, about 10 on a full-grown chamber, those of each chamber usually not continuous with those of adjacent chambers, high and very thin and sharp, to- ward the base and apertural ends of the test becoming broken up into spinose or irregular short portions; the wall between the costae and the costae themselves distinctly granular; aperture circular at the end of a distinct cylindrical neck, often spinose and with a phialine lip. Length up to 0.85 mm. Distribution —Type-specimen (U.S.N.M. Cat. No. 17574) from Albatross station D2029, in 1,168 fathoms (2,136 meters), off the northeastern coast of the United States. This is a very common species in the cool waters of moderate depths off the northeastern coast of the United States, and at a very few stations just south of Cape Hatteras. It occurs in great numbers, making up a decidedly important proportion of the bottom material. It is very different from typical U. pigmea D’Orbigny, as a refer- ence to D’Orbigny’s figure and model will show. Our species may be distinguished by the high plate-like costae, the very granular sur- face, even of-the costae, spinose or broken plates at the apertural and initial ends, and the often spinose neck. It is represented fur- ther southward by the following variety. FORAMINIFERA OF THE ATLANTIC OCEAN, Uvigerina peregrina—material examined. 167 | Bot- Depth No. of . | tom pat. Coll. of— soc Station.

Distribution—Type-specimen (U.S.N.M. Cat. No. 17465) from Albatross station D2568, in 1781 fathoms (3257 meters), off the north- eastern coast of the United States. The same variety has occurred at several other stations in the same region but not elsewhere. This is distinct from the typical form and might be referred by some authors to U. tenuistriata. In the Challenger Summary of Results volume, U. tenuistriata is recorded from off Bermuda and off the northeastern coast of the United States, and these records may be our variety.

Description.—Variety differing from the typical in the usually smaller size, the more inflated and remote character of the last chamber, and the shorter stouter form of the whole test. Distribution—Type-specimen (U.S.N.M. Cat. No. 17666) from Albatross station D2400, in 169 fathoms (309 meters), in the north- ern part of the Gulf of Mexico. The variety also occurs at several other stations in the same vicinity, near Cuba, off Central America in the Caribbean, and off the southeastern coast of Brazil with one station on the southeastern coast of the United States. It is possible that the species figured by Brady, Parker, and Jones*® may belong here. The Albatross material from the Bra- zilian coast is larger than that from the Gulf of Mexico. 7 Trans. Zool.

UVIGERINA PORRECTA H. B. Brady. Uvigerina porrecta H. B. Brapy, Quart. Journ. Micr. Sci., vol. 19, 1879, p. 60, pl. 8, figs. 15, 16; Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 577, pl. 74, figs. 21-23.—Harbtanp, Journ. Quekett Mier. Club, ser. 2, vol. 9, 1905, p. 218. One of the Challenger stations given for this species is off Ber- muda, 435 fathoms (796 meters). The others are in the Pacific. Earland records it as very rare at Bognor, Sussex, England. There seem to be no other Atlantic records. I have failed to find it in the western Atlantic, even in the tropical portion, and it seems that the specimens recorded from the Atlantic should be reexamined to see if they are really the same as the species characteristic of the Indo- Pacific. UVIGERINA OCCIDENTALIS, new species. Uvigerina angulosa CUSHMAN, Publ. 311, Carnegie Inst. Washington, 1922, p. 34, pl. 5, figs. 3, 4. Description.—Test minute, elongate, triangular in transverse sec- tion, the periphery somewhat lobulate; chambers distinct, those of the last-formed portion becoming more distinct and remote; sutures distinct and depressed; wall ornamented with comparatively large, high costae on all the chambers except the last ones in the adult, apertural end drawn out into a tubular neck with a slight phia- line lip. Length not exceeding 0.50 mm. Distribution—Type-specimen from the Tortugas region. It has also occurred at several Albatross stations, ranging from the eastern 170 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. angle of South America into the Caribbean and Gulf of Mexico, one south of Cape Hatteras, and another south of the latitude of New Lock, It is evidently a species with a southern range and occurring in yvarm waters. It may also be found to extend to the Indo-Pacific where Uvigerina angulosa has been recorded. The last-formed chambers in their loose arrangement, the rather coarse costae, the small size and thin hyaline test, will distinguish it from either the typical British U. angulosa, or the western Atlantic form of that species. It is probably the same as that I have recorded from the Pleistocene of Panama®? and from the Pliocene, Waccamaw formation on Waccamaw River, South Carolina.*! It resembles the Pacific collections I have had from off Hawaii and elsewhere.*? Uvigerina occidentalis—material examined. Bot- Depth No. of : tom ie Coll. of— speci- Station.

Description.—Test elongate, tapering toward either end, com- posed of numerous chambers, three making each whorl; chambers compressed at two sides, making a decided angle in the middle and making up a trifacial test, triangular in end view and section; wall more or less costate, usually the costae numerous and distinct; aperture with a short tubular neck and with a phialine lip usually more developed on the outer side. Length up to 1 mm. Distribution.—F rom the above synonymy it will be seen that this species is apparently very widely distributed. Just how many of the above references are to typical material it is impossible, without a study of the originals, to really determine. In the Atlantic the species is well developed and characteristic of the comparatively shallow waters of western Europe. On the western side of the At- lantic it is well developed and abundant only on the northeastern coast of the United States, with scattered records in the colder waters nearly as far south as Cape Hatteras. It is most abundant in waters of 100-300 fathoms (183-549 meters) off the New Eng- land coast, and to or beyond the Grand Banks. It is a thick-walled form with somewhat rounded angles, differing in these particulars from European material. The species is replaced in the warm tropical waters of the Gulf of Mexico and Caribbean by another species, as it is in the Ter- tiary of the Coastal Plain of the southeastern United States. It is 56148—23——13 172 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. to be suspected that many of the records from various parts of the world when carefully compared with typical material from western Europe will be found to be different. The form originally described by Brady as U. spinipes H. B. Brady and later referred to U. angulosa as a variety, has not been found in the Atlantic and is evidently a distinct Pacific species.

FORAMINIFERA OF THE ATLANTIC OCEAN, 173 Description.—Test elongate, composed at least in the microspheric form of a series of chambers arranged tri- or bi-serially, followed by a later uniserial development; walls hyaline and perforate; aper- ture in the uniserial portion central and terminal, usually with an elongated neck and flaring lip; interior of the chamber with a tubular connection running from the base of the apertural neck to the lip of the aperture below; wall smooth or ornamented by costae, pits, etc. Both microspheric and megalospheric forms occur in the various species of this genus. In the microspheric form the early chambers are biserial or triserial, and there is usually a considerable number of them before the adult uniserial development takes place. In the megalospheric form the uniserial condition is taken on much earlier, after only a few of the triserial or biserial chambers are developed. The genus seems to be limited to the Tertiary, and in the present oceans is best developed in tropical waters under 500 fathoms (914 meters) in depth. SIPHOGENERINA ADVENA Cushman. Plate 42, fig. 15. Siphogenerina advena CuSHMAN, Publ. 311, Carnegie Inst. Washington, 1922, p. 35, pl. 5, fig. 2. Description—Test elongate, somewhat compressed, early portion either triserial or biserial, later portion, which makes up the larger portion of the test, uniserial; chambers numerous, distinct, inflated; sutures somewhat depressed, the early portion and a part of the uniserial portion with fine, longitudinal costae, more or less broken, followed by two or three chambers slightly spinose, after which the remaining chambers are smooth and very finely punctate; aperture elliptical, each one connecting with the preceding by an internal funnel-shaped tube. Length up to 0.65 mm. Distribution—This species which was found to be common in the Tortugas region of southern Florida has occurred at two stations in the Albatross Atlantic collections. One of them is in the western part of the Caribbean off Central America, the other off the Carolina coast. This is the general distribution of many species that extend throughout the West Indian region and along the coast of South America so that this species probably occurs widely distributed in this general region. Goés in 1896 ** gave a new name Sagrina pygmaea Goés to a small species recorded by him from the Caribbean in 300 fathoms (549 - meters). This was originally figured as “ Z'extularia Pennatula, var. aculeata forma Bigenerina.” ** Goés’s figure does not show the 83 Bull. Mus. Comp. Zoél., vol. 29, p. 51. % Goés, Kongl. Svensk. Vet.

Length up to 1 mm. Distribution—There are published Atlantic records for this species as follows: “shore sands, Bermuda, West Indies, Panama ” (H. B. Brady); Tortugas region (Cushman). There is a single specimen in the Albatross collections from D2150, in the Carribbear. off Central America. The species is much more common in the Indo-Pacific. It is one of the species which occurs as far westward as the Kerimba Archipelago off southeastern Africa; Ceylon, as far north as Southern Japan, thence across to Hawaii and Samoa, finally ap- pearing in the tropical western Atlantic.

Mus., vol. 4, 1921) ‘p. 279; pl. 56,’ fig.’ 8: Description.—Test either somewhat compressed or nearly cylindri- cal, very slightly tapering from the somewhat rounded initial end to the greatest width near the apertural end; chambers comparatively few, rather broader than high, slightly inflated; sutures distinct, the basal portion of the last few chambers somewhat excavated and tending to bridge the sutures between the excavations at regular in- tervals; wall with a coarsely pitted surface; aperture circular, ter- minal, at the end of a short neck, usually with a distinctly phialine lip. Length of Atlantic specimens not over 0.60 mm. Distribution—This is a widely distributed species, although, as will be noted later, there may be more than one variety. The origi- nal stations given by Parker and Jones are Red Sea (near the Isle of Shadwan) at 372 fathoms (681 meters); Abrohlos Bank, 260 fathoms (476 meters); Australian Coral-reefs, 17 fathoms (31 meters). Brady gives the following notes as to its distribution, in the Challenger report: The geographical area inhabited by Sagrina dimorpha is wider than that of any other species of the same genus. It extends as far north as Bukken and Oster Fiords, near Bergen, Norway (Norman); and a single specimen from the Scottish coast is reported by Mr. Robertson. It has been further noticed in the North Atlantic, off Gomera, Canaries, 620 fathoms (1,134 meters); and off Culebra Island, West Indies, 390 fathoms (713 meters) ; in the South Atlantic, off Ascension, 420 fathoms (768 meters); and on the 176 BULLETIN 104, UNITED STATES NATIONAL MUSEUM. Abrohlos Bank, 260 fathoms (476 meters) (Parker and Jones), in the Red Sea, 580 fathoms (1,061 meters) ; in the Southern Ocean, off Prince Edward Island, 50 to 150 fathoms (91 to 274 meters) ; and in the South Pacific, off Tahiti, 420 fathoms and 620 fathoms (768 meters and 1,134 meters): off Ki Islands, 580 fathoms (1,061 meters) ; and off Kandavu, Fiji, 255 fathoms (460 meters). He later in 1887 records it from shallow water off the coast of the British Isles. It is also recorded in the Atlantic from the Norwe- gian Sea (Goés) and off the west of Scotland (Heron-Allen and Earland). Sidebottom records it from the east coast of Australia in 465 fathoms (850 meters), Bagg from off the Hawaiian Islands, and I have recorded several stations in the Western Pacific. The Albatross collections show it to be present at five stations, one off the coast of Georgia, one between Cuba and, Yucatan, and three in the Caribbean. These, as the table shows, are in considerable depths. This shows a very wide distribution for this species. A study of the Atlantic specimens and a comparison of them with the other material available shows the following results. Our Albatross specimens from the Atlantic seem to be more compressed, the uniserial portion smaller in comparison and of fewer chambers, and the reéntrants of the basal portion of the chambers reduced or wanting. The original figures of Parker and Jones show this char- acter and not that of the Pacific specimens. One of the original stations of Parker and Jones was the Abrohlos Bank and it is to be suspected that the figured type specimen came from this locality. This is more strongly indicated by a comparison of this type figure with that given in 1888 from the Abrohlos Bank. The two strongly suggest that both figures may have been drawn from the same specimen. The figure given by Goés in 1894 from the Atlantic is also of this form. Brady’s figures and mine from the Pacific have the cylindrical form, the greater proportion of the uniserial devel- opment, and the deeply incised ventral border to the. chambers. This suggests, therefore, that there is a varietal form in the Pacific. Siphogenerina dimorpha—material examined. Bot- Depth No. of : tom f ae Coll. of— | speci-| Station.

This genus includes rather ill-defined forms, suggesting the so- called “ wild growth” seen in the final chambers of certain species of Polymorphina. Just what its relations are to the rest of the Lagenidae is not really determined. It seems to occur in the Jurassic and there are one or two recent species. RAMULINA PROTEIFORMIS Flint.
