By William Healey Dall, Honorary Curator of Mollusks, United States National Museum. The collection of recent Brachiopods, in the United States Museum began with the material obtained by the United States Exploring Expedition under Wilkes, mostly in the Magellanic region. Since then the chief additions have been received from the dredgings of the steamers of the United States Coast Survey and the United States Fish Commission, now the Bureau of Fisheries; my own dredgings in the North Pacific and Bering Sea; and the material in the Jeffreys Collection purchased by the United States National Museum, chiefly comprising specimens from the North Atlantic and the Mediterranean Sea. Valuable contributions have been received from the West Indies and Florida dredgings of Mr. J. B. Henderson, jr., and from the University of Tokio, collected by Prof. E. S. Morse. Miscella- neous small purchases and exchanges have filled various gaps. The total reserve series now contains 181 different forms repre- sented by over 6,000 specimens from various localities, including many original types, and of these some 33 are new. Our principal weakness lies in the absence of some recently described forms from the southern hemisphere, and a few of the abyssal rarities. I have not had the privilege of examining the collection of the late Thomas Davidson now in the paleontological department of the British Museum (Natural History), but with this possible exception the collection in the United States National Museum is, I believe unrivaled. In the preparation of the list the classification of Beecher and Schuchert has in the main been followed, supplemented by data from later researches. In reviewing the nomenclature it was found that some changes were necessary, due to the fact that Dr. Thomas Davidson, Mr. J. Gwyn Jeffreys and some others of the earlier writers seem to have been little interested in this branch of the subject, and often included in their synonymy admittedly earlier names than those they habitu, ally used, with no consideration of the claims of priority, as in the case of the two species described by Pallas, of which one was accepted Proceedings U. S. National Museum, Vol. 57— No. 2314. 261 262 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 57. and the other ignored, though the latter was completely identified. Moreover, in the case of Doctor Davidson's Monograph of the Recent Brachiopoda, his premature death before publication left his synonymy in such a confused condition that it is absolutely essential to verify every reference by an inspection of the original work cited, if accuracy is to be secured. All this has resulted in changes, some of which will no doubt be much regretted, but which are inevitable if the character of the work here presented is to be kept up to the ordinary standard of accuracy. In tabulating the specimens the column under “Collector” refers not only to the actual collector but, when he is not known, to the source from which the specimen was received. “ B. F. ” is an abbrevi - ation for the Bureau of Fisheries, formerly the United States Fish Commission. When practicable the depth is also cited, but for most of these cases much more information, such as temperature of the water, character of the bottom, etc., is also on record. It is hoped to supply figures of the new forms at a later opportunity. Specimens suitable for filling gaps in the collection, or enlarging scanty series, are much desired. Collectors or dealers having such material available are requested to communicate with the United States National Museum. Class BRACHIOPODA. Order ATREMATA. Family LINGULIDAE.

The valves are nearly always more or less streaked with brown, especially on the sides where a pair of brown streaks are of frequent occurrence. The peduncle varies in length among individuals and is sometimes attached to a small pebble or bit of shell and in many cases entirely free or incased in an irregular sand tube. The most northern locality reported for the species is at Monterey Bay, California. A commensal Crepidula ( glottidiarum Dali) often completely covers each valve. GLOTTIDIA PALMER I Dall.

My doubts as to the specific distinctness of this form from G. albida are not entirely removed, although the adults show some marked differences. Dr. Thomas Davidson, however, was of the opinion that they are distinct. He mentions the presence of a very similar species, G. lesueuri in the lower Silurian. GLOTTIDIA ALDEBAP.TI Brodcrip.

The species is confused with G. pyramidata Stimp- son, which is not only totalty unlike G. audebarti specifically, but comes from a different zoological province. The reference under Sowerb}7 should be to the Thesaurus and not to the Conchologia Iconica. Glottidia audebarti is a large species with the umbonal half mostly white, the distal half of the valves painted with a brilliant blue green, unlike any other species in the genus. The spelling of the original name was corrected by Deshayes to agree with the correct spelling of the name of Baron d’Audebart de Ferussac, whom Brod- erip desired to honor.

I do not find that Cuming himself ever visited Martinique, and am now disposed to think his species was not really American. Cuming’s localities, except for specimens of his own collecting, are notoriously unreliable. Glottidia pyramidata is a small narrow whitish or horny shell, in most cases without calcareous matter enough to dry in normal shape. It has rarely a few brownish specks upon it but never shows any green- ish color. Brooks, Morse, and Doctor Beyer have exhaustively described its anatomy and characteristics. As in most cases the southern specimens are larger and more solid than those from northern stations. It is believed to live not much over a }Tear. It was found by Henderson at a depth of nearly two feet in the sand among roots of sea grasses. Order NEOTREMATA. Family CRANIIDAE. Genus CRANIA Retzius. Crania Retzius, Schrift. Berl. Ges.

Type locality. — Near Bird Island, Hawaiian group, at United States Bureau of Fisheries station 4158, in 20 to 50 fathoms, bottom temperature 78° 6, collected by the United States Steamer Albatross, one lower valve adhering to a specimen of Peristernia crocea Gray. No species of Crania having been reported from the Hawaiian group, this specimen has a peculiar interest. I should have felt hardly justified in naming it from a single lower valve were it not that it differs from all the described species in its elasticity and fibrous texture and the almost entire absence of calcareous matter. A microscopic scrutiny of a large series of Xenophora pallidula in the hope of finding other individuals proved vain. It did reveal a minute specimen of Discinisca about two mm. in diameter, with short cirrhi, which, when an attempt to detach it was made, snapped into space and could not be found. This genus is also new to the islands. It came from station 4099, on the north coast of Maui in 152 fathoms, temperature 60° 7. CRANIA PHILIPPINENSIS, new species. Shell depressed, attached to a substratum by the whole surface of the lower valve, whitish internally, reddish brown externally, the apex of the upper valve prominent, the posterior margin straight, the general outline rounded-quadrate; upper surface irregularly lamel- lose, the lamellae not raised, but with small, threadlike, raised, radiating, sparsely distributed lines continuous only on the single lamella; interior of upper valve minutely granulose, with a margin defined by a raised inner ridge, not radiately sculptured, the pedestals of the adductors slightly raised, not coalescent medially, with a small prominence in the middle line just below them; the anterior spaces carry impressions of five or six brachial lobes on each side ; the space behind the adductor ridges, with a central diamond-shaped depression the two scars above it not elevated, evenly rounded; interior of No. 2314.

Another peculiarity of this species is that the lower valve is subcorneal and attached to its substratum only by the central apex instead of by its whole surface as in the typical Crania. In one speci- men this attached tip shows a central depression, as if there might have been in the very young a peduncular orifice, but as all the speci- mens were loose valves, dead specimens when dredged, this is doubt- fuL Family DISCINIDAE.

Large, lamellose, flexible, without radiating sculpture. Ex- amples: D. lamellosa, D. laevis. B. Large, less lamellose, with feeble irregular radiations, more solid. Examples: D. strigata, D. cumingi. C. Small, with regular radiating sculpture, not lamellose, solid. Examples: D. stella, D. antillarum. Groups A and B are confined to the western coasts of the Americas ; group C to the east coast of Asia and associated islands and the shores of the tropical Atlantic. The discrimination of the species, especially if the valves are a little worn, is not always easy, but the outside sculpture of the lower valve and the form of the peduncular orifice afford excellent and easily recognizable characters. They have also the advantage of being less liable to wear and incrustation than the upper valves. In the case of D. lamellosa, there is a very short groove at the center of the valve suggesting a closed central pedicel opening in the very 276 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 57. young; the base is evenly closely concentrically lamellose; the pedun- cular area is ovate-lanceolate, deeply impressed, with the opening narrow, elongate, close to the posterior margin and usually separated from it by a thin papyraceous narrow band which is in the majority of dry specimens broken away so that the orifice is not entire, but has the aspect of a sulcus. This species lives near low water and is often exposed in large masses at extreme ebb tides. DISCINISCA LAE VIS Sowerby. Orbicula laevis Sowerby, Trans. Linn.

The exterior of this valve is well figured by Reeve (fig. 4b), having low arcuate lamellae starting from the peduncular large depressed area and surrounded by a marginal band of concentric lamellae. The foramen is narrow and not so near the margin as that of D. lamellosa. Davidson’s figure 9 is a poor copy of Reeve ; the base shown in figure 11 of Davidson’s plate 26, is that of D. lamellosa and not D. laevis. The posterior extremes of the horny part of the valve meet but do not coalesce behind the peduncular area. DISCINISCA STRIGATA Broderip. Orbicula strigata Broderip, Trans. Zool.

The California specimens above cited are probably adventitious, from scrapings of small coasting craft doing business to the southward. When fresh the radial stripes of dark color distinguish it sharply from any other species of the genus, but these gradually fade out in the cabinet. The texture is much more calcareous than that of any other west American species. The sur- face of the upper valve is quite regularly radiately threaded, espe- cially in the young. The horny part of the lower valve is continuous behind the peduncular area, which is very large, the surface of the valve about it is regularly radiately striated. In old specimens the stria tion is obsolete or absent on the peripheral part of the upper valve, and the surface is apt to be quite irregular. DISCINISCA CUMINGII Broderip.

This is a thinner and more distinctly reticulated species than D. strigata, without dark blackish radial stripes, and less calcareous. The basal valve has a large peduncular area, which is figured by Davidson. The sculpture outside of the area is concentrically lamel- lose with faint radial striae, according to Broderip and Davidson.

The synonymy of this genus has been left in a confused state by authors and the tracing of citations to their source has revealed a number of errors which have been extensively copied. Fischer states in his Manuel, (page 1330), “Le genre Thecidea cree nominalement par Defrance en Ferussac, 18.19, n’a ete caracterise qu’en 1822 dans le dictionnaire classique d’histoire naturelle; le m£me annee, Brong- niart cite comme type le Thecidea radians. ” This is not quite exact. The true history of the name is as follows : Thecidea occurs as a nude name in Ferussac’s Tableau. Brongniart in his description of the chalk of the hill of Maastricht (taken chiefly from the work of Faujas de Saint Fond on that locality, published in 1799) cites four fossils of which the second and third are Thecidea radians and hieroglyphica of Defrance. There is no reference to either in the text, but after the first name is a reference to Faujas ; figure 8 of his plate 17. This of course in conformity with modern usage fixed the genus and the type. Probably in ignorance of this citation, Ferussac in the Dictionnaire Classique in 1822, referred to the genus, under the article Brachiopodes, only by its vernacular name and as “non encore decrit” (p. 47). In this publication it is only in 1830, that Deshay es latinizes the name and diagnoses the genus. Also Sowerby in 1823, while at Doctor GoodalFs recommendation correct- ing the unpublished name to Thecidium, states that he does not name the figured recent species because he “ will not interfere with Defrance’s unpublished account of the genus. ” Thus it is clear that the name of Defrance circulated among his colleagues and correspondents several years before it was formally described and it is only by the accident of the citation of Faujas’ fig- ure by Brongniart, that the name is preserved in its original form. The Thecidea radians Defrance, according to Bronn is a synonym of Terebratulites papillatus Schlotheim, 1813, and was later the T. pumila of Lamarck but not of Sowerby. The type of the genus therefore is Thecidea papillata (Schlotheim) from the Cretaceous of Maastricht. The recent forms differ sufficiently from the fossil type to have been separated as follows by Munier Chalmas. Subgenus Lacazella Munier Chalmas. Lacazella Munier Chalmas, Bull.

The cavity of the beak in the attached valve in fullv-developed specimens shows a median septum supporting on each side an excavated plate which anteriorly projects more or less beyond the septum in a prong or point. In some specimens the septum only appears deep in the valve; in others it is prominent at the commis- sure between the plates and rises between them as a keel. In the fullest development of the arrangement the septum rises to the upper vault of the beak, thus dividing the cavity, in combination with the plates (“coques” of Lacaze Duthiers), into four compart- ments. The space between the forward prolongation of the plates is not deep, but triangular, and in none of the specimens which I have examined have I seen anything resembling the squarish or bilobed plate figured by Davidson (pi. 23, fig. 14 and fig. 15&). I presume in these cases the prongs have been broken off. One of the characters used by Allan Thomson to separate his Thecidellina from Lacazella is the presence of prongs in the former, but, as above stated, the prongs are quite evident in any well-preserved specimen of the type of Lacazella mediterranea. LACAZELLA MAURITIANA, new species. This species has a remarkable resemblance to the preceding, with which it has been confounded, but differs by having in the apical cavity of the attached valve instead of a platform supported by a septum, only two long, slender, excavated, upturned processes com- pletely isolated medially, with no sign of a septum. The outer sur- face is minutely regularly granular. In other respects it agrees closely with L. mediterranea. Cat. No. Locality. Collector. Number of speci- mens. 173593 Mauritius Sir H.

The space behind the dental props is very small and solidly filled with cement in the older specimens. The valves are unusually thick, solid and cal- careous. Until I got more perfect specimens than the original types, I suspected that the H. columns of Hedley, might be identical, but with the receipt of perfect individuals an inspection showed suffi- cient distinctions in and about the cardinalia. The pedicel tube, homologous with the “ collar ” of Jackson, but greatly produced and developed, would certainly be taken as of gen- eric value in a fossil species and is not distantly related to the arrange- ment in the Devonian Pseudosyrinx. BASILIOLA POMPHOLYX, new species. Shell pellucid, much inflated, light gray, polished, without radial striation and only very faint incremental lines; pedicel valve with a wide concave mesial fold which is not laterally well defined except at the margin where the valve projects in a squarish fashion; the beak is low, the foramen small, under the apex; the deltidial plates wide, firmly united in front of the foramen and produced in a sort of gutter in front; when not worn off the extremity of this gutter extends be- yond the plane of the incurved beak; internally the lower extensions of the plates unite without any visible suture to form a broad tube of which the anterior edge is free from the dome of the valve and ex- tends forward as far as the beginning of the dental props; the hinge teeth are very small and weak but strongly cross-striated; a narrow groove extends from under the tube mesially as far as the rather small muscular impressions, the dental props are thin and incon- spicuous; the brachial valve is almost hemispherical in inflation, with a broad squarish anterior fold; the crural plates wide, short, separated clear to the apex, the crura very small, short, guttered below; the cavity of the beak sometimes with a low thread-like septum extending forward to the muscular scars, sometimes with a shallow groove which after separating the muscular impressions bifurcates widely, extending nearly to the anterior margin. Height of shell 26; width 28; maximum diameter 17 mm. 292 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 57.

LIST OF RECENT BRACHIOPODA — DALL. 293 The specimens from the cold water off Kamchatka were much coarser and more solid than the others, but otherwise similar. A considerable proportion of the specimens are more or less distinctly bilobed, this condition not being accidental, as supposed by Doctor Thomson, while others show hardly a trace of lobation. Both valves are medially more or less concave, the sulcation, if it may be called so, being “ opposite.” It is much less evident in specimens from colder water. Genus ATRETIA Gwyn Jeffreys.

Current nomenclatorial usage would reject Cryptopora as homony- mous with Cryptoporus , but whether the practice would extend so far as to reject Atretia on account of Atretium is more doubtful.

It is perfectly obvious that the name caput-serpentis is excluded from use in the latter connection by all rules. Those who retain some skep- ticism will do well to consult Hanley’s book. It appears that the spiculation of the Mediterranean form differs from that of the North of Europe species and Blochmann confirms the opinion of Davidson that the former should be regarded as distinct. No. 2314. LIST OF RECENT BRACHIOPODA — DALE. 297 The earliest name for the Mediterranean form is emarginata of Risso, but the bilobate form is not peculiar to Mediterranean speci- mens. There are in the Jeffreys collection numerous specimens of retusa with this character, and in fact bilob ation seems to occur in almost any of the less inflated strongly striated species of the genus as a mutation. The varieties angustata and grandis of Jeffreys seem to me mere mutations of form, without special significance. On the other hand T. septentrionalis and T. unguicula, which have been frequently treated as varieties of T. retusa, are positively established as distinct species by Blochmann on the basis of their spiculation although it is often extremely difficult to separate them merely on the basis of the shells.

This species can generally be distinguished from T. retusa by its finer sculpture and more oval form, but varieties approach one another very closely so far as external aspect is concerned. The usual mutations of form occur very often. This species is subject to the (commensal ?) growth of a sponge which when young appears like a normal pubescence, as in T. retusa , but when full grown becomes a spongy ball in which the brachiopod is entirely concealed. The north European specimens appear to be correctly identified, but their spicules have not been examined. TEREBRATULINA UNGUICULA Carpenter. Tertbratula unguicula Carpenter, Proc. Zool.

Steams 2 219900 Off Redondo, California, 60 fathoms Dr. Tremper 1 On a bunch of coral rock hooked up by fishermen from 60 fathoms off Redondo, California, several brachiopods were attached which seemed to me different from the Laqueus californicus usually found there, and after my return to Washington, Dr. R. H. Tremper, the collector, generously donated one of them to the United States National Museum. It was a great surprise to find the Japanese species on our coast, but there seems no doubt about the identifica- tion of the shell. The dried animal showed the reflected part of the brachia comprising the median coil was not, as usual, united by a thin band of tissue but the right and left brachia appeared to be quite free from one another medially except at the posterior com- missure; while in the nearest related species, T. callinome, a mem- brane exists between the two arms of the reflected loop and back over the shelly loop to the vicinity of the adductors. The spiculae were remarkably visible under a hand lens in beautiful stellate forms and profusely invading the tissues everywhere. The genital sinuses comprise two groups separated distinctly from one another by a space entirely free from sinuses and each group comprising about one half the space of its side of the valve, extending nearly to the anterior margin of the valve and composed of a multitude of small reticulations densely carpeted with spiculae. The species reported by Fischer and Oehlert from Magellan Straits, under this name, is said by Blochmann to be distinct. TEREBRATULINA CALLINOME, new species.

This species has been received with the label “ T. japonica” and it is likely that young specimens have been confused with that species which is of the retusa type, while the present species leans toward T. crossei. The reception of abundant material gives an opportunity for dis- crimination between similar species which can not be afforded by a few specimens. TEREBRATULINA JAPONICA Sowerby.

Morse The above are typical and I feel no doubt of the identity of japonica Sowerby and angusta Adams. I think this shell was more or less confused with T. callinome by Davidson and others, doubtless from want of sufficient material for comparison. The valves show no sign of folding or bilobation. TEREBRATULINA REEVEI, new species. The following material I believe to belong to T. japonica Adams and Reeve (fig. 1, 1850) not Sowerby. I am uncertain whether it should be regarded as a distinct species or not, though from the entire absence of large specimens, such as occur in Japan, I am inclined to believe in its distinctness. It differs from the young specimens of T. japonica Sowerby by its tendency to bilobation, and in a general way by its usually coarser sculpture, its coarsely crenulated inner margin, the loop with the lower medial portion projected as a sharp point while in ja'ponica Sowerby it is squarely truncated in front. The brachia are like those in T. retusa, the genital sinuses reticulated, adjacent, and occupying the middle half of the shell with no distinct branches, and with a covering of elegantly stellate spiculae, easily visible under a hand lens. An average specimen measures 8 mm. long by 6.5 wide, and about 3 mm. in diameter, the largest about 15 mm. in length. Under the circumstances I propose to give it the provisional name of reevei.

The name Gryphus Megerle has been rejected by authors on the ground that it was preoccupied by an alleged genus Gryphus of Brisson in his work on birds. This, however, is due to an error. Brisson de- scribed no genus Gryphus but used the word as a specific name for the Condor, one of the species of his genus Vultur (p. 28). Hence the brachiopod name is not, in a generic sense, preoccupied by its occur- rence (p. 473) in Brisson’s Ornithologia. The name has been used by No. 2314. LIST OF RECENT BRACHIOPOD A — DALE. 511 several authors in a generic sense later, but except in the case of the Museum Calonnianum, all are subsequent to Megerle. The Museum Calonnianum has been rejected as a source of valid nomen- clature by the International Committee on Nomenclature, but in any case it did not originally contain the name Gryphus which at some later date was written in as a substitution for Lacinia in some copies. There is no way of determining the date of this manuscript emenda- tion, which in any case could not be accepted, since the circulation of a manuscript does not constitute publication. * GRYPHUS VITREUS Born.

It is curious that both should have come from Sardinia. The elongatus is narrow almost subcylindrical, and as there are four specimens of it, it can hardly be regarded as a deformity. The other variety, dilatatus, is lenticular, subcircular and much less inflated than the normal vitreus. If found in another faunal area one could hardly hesitate to regard it as a new or at least a distinct species. Except in form they do not appear to differ from normal vitreus. The varietal names used above were attached to the specimens by Jeffreys, but I have not found that they have been published. GRYPHUS AFFINIS Calcara. Terebratula vitrea var. minor Philippi, En.

The latter average larger and more inflated and have a much thicker and more solid shell, judging by a large series received from Seguenza. No. 2314.

None of my specimens of G. uva show it except as a thick- ening so trifling that it does not interrupt the passage over it of the point of a pin. GRYPHUS FULVA, Blochmann.

F 1 The specimen from deep water was dead and contained mud, when dredged. The true G. uva is a shallow water species. I have seen none from south of Peru. I strongly suspect that more than one species is involved in Davidson's discussion of T. uva both in the Challenger report and his monograph. The genital sinuses in G. uva are reticulate and occupy the middle third of the valve with a vacant space mesially. The * ‘septum" in the dorsal valve, in the specimens I have been able to examine, is extremely feeble, and often absent altogether. Something of the kind may be found in some specimens of almost any Terebratuloid, as for instance G. vitreus. GRYPHUS MOSELEYI Davidson. Terebratula moseleyi Davidson, Proc. Roy.

LIST OF RECENT BRACHIOPODA — DALE. 319 No. 64255 was submitted to Mr. Davidson and pronounced to be his T. moseleyi, agreeing very closely with his figures in the Challenger report. The other specimens appear to be conspecific, though the Panama specimens are dead and dilapidated valves. The older specimens show three marked short grooves separated by the mus- cular impressions which are more or less raised, in the pedicel valve, and in senile specimens these are quite deep. There has been some doubt expressed as to the identity of the above specimens with the species dredged at Kerguelen, notwithstanding their agreement in the external features. I confess to some doubt myself and would suggest for the species in case they prove distinct the name of Gryphus martinicensis , the specimen numbered 64255 being taken as type.

There is a faint ridge between the muscular impressions, in the brachial valve, and another in the pedicel valve. The exterior is smooth, the foramen entire, there is a well marked “collar” within the foramen. Mr. Davidson had a specimen of this species which he figured in his paper on Japanese brachiopods above cited. He did not describe it because the cardinalia were defective and he was doubtful about the genus. I have seen no subsequent reference to it. GRYPHUS DAVIDSONI A. Adams. Terebratula davidsoni A.

But the reception of many specimens has enabled me to clear this up, the former species being many times larger than the latter which is extremely uniform. If the difference in color be regarded as of varietal rank, the name rubrotinda would apply to the specimens with scarlet radial lines. Genus MEGATHYPJS Orbigny.

The name ungula, applied by Retzius to an unidentifiable figure in Gualtieri, is earlier, but the figure is not only unidentifiable but bears not the slightest resemblance to the present species. The specimen received from Ancey was labeled by him Argiope cordata and said to have been collected by Marshall. That it really came from Guadeloupe may well be questioned. The specimens are identical with the Mediterranean form. The usual variations in the number of ribs, convexity and lateral extension, run through the series above enumerated. 332 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 57. Family TEREBRATELLIDAE.

The genus Miihlfeldtia is characterized among other things by the peduncular foramen being normally confined to the beaked valve as in most Terebratellidae, the extension of the foramen to the brachial valve being due to wear and to that extent abnormal; both valves are free and similarly sculptured. In the present genus the foramen normally is confined to the brachial valve, only by wear encroaching on the other; the brachial valve is applied to the sub- stratum, reproducing its irregularities and except for those is smooth, while the upper valve has radial sculpture.

Most of the figures indicate the foramen as encroaching on the upper valve, but this is abnormal. An examination of a perfectly unworn specimen will show conclusively that the foramen is normally entirely confined to the brachial valve. 336 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 57.

On examination of the loop I am compelled to the conclusion that the details do not agree with the type of the genus Kingena as figured from the original fossil, but that there is really no essential difference between the loop of alcoeki and Frenvlina sangmnolenta. I have therefore referred the species to Frenulina. FRENULINA MAUIEnSIS, new species.

This species resembles the variety rubescens of T. transversa in color, but is much more inflated, sometimes white, with red color only on the ribs, but may be instantly distinguished from any of the forms of transversa by the fact that its mesial fold is directly opposite to that of any of them, the sulcus being in the pedicel valve while in trans- versa it is in the brachial valve. It was confused by Davidson with the red variety of transversa. After a study of the variations in plication observed in this and other species of Terebratelloids of the North Pacific, I conclude that too high a systematic value has been placed on the various modifi- cations, in this group at least, by some excellent students of the brachiopoda.

F 23 The plus mark stands for many young specimens of various ages in addition to the counted adults. Comparing the incongruity of the types of plication with other characters of the species concerned, it does not seem to me to have any serious systematic value in the group of recent forms here under consideration. I am not able to accept the compliment which Doctor Thomson has graciously con- ferred upon me in proposing on that basis a new genus for the T. obsoleta. It differs from the other species of the coast in its thin and delicate polished shell which contrasts strongly with the solid dull-surfaced character of the others; its brilliant scarlet painting is equalled only by such species as Laqueus pidus and Frenulina sanguinolenta. In the completely adult there is on either side of the narrow deltidia a flattened area with a keeled edge. Beecher’s diagram (pi. 3, fig. 15) of the loop is good but does not indicate the fact that the cardinal plate is divided to the apex of the valve where there is a thin wide cardinal process. A completely adult specimen measured 39 mm. high, 42 mm. wide, and has a diameter of 21 mm. It exhibits the wildest variations in plication from a barely preceptible protractive arcuation of the anterior edge of the pedicel valve to a very strong squarish ridge with four or five minor denticulations, to a ribbed form with ten or twelve subequal modifications of the margin. There is in the pedicel valve a very low slender septal median keel in the hollow of the beak which terminates in a short broad low ridge with an excavated top. There are small props to the hinge teeth from which in senile specimens an arcuate raised line runs down into the dome of the valve. In T. transversa the props are almost obsolete and stop short behind the teeth; in the completely adult there is a low flattish septal ridge extending beyond the middle of the pedicel valve and forked at its anterior extremity. In fairly adult T. caurina I find no trace of this ridge. In both there is a wide thin cardinal process and nothing resembling a cardinal plate between the dental No. 2314.

Notwithstanding the fact that MagaseTla aleutica is neatly shaped and prettily colored while Ter ebratalia frontalis is dull gray, coarse and usually misshapen, I am pretty well satisfied that the former should he referred to the immature stage of the latter. T. frontalis has an enormous pedicel opening with inconspicuous widely separated deltidia, no septal ridge in the pedicel valve, short props to the dental processes and the faintest possible indication of a pro tractive fold on the anterior edge of the valve; the brachial valve has a small cardinal process, there is a narrow platform with a con- cavely arcuate anterior edge between the crural ridges; instead of a septum a sharp groove starts from under the platform in the cavity of the beak and extends be}rond the middle of the valve where a low short triangular septum, much farther forward than usual, rises out of the groove to support the loop. Davidson’s figures show the crural plates entirely separated but this is not the case with my specimens. The muscular impressions are more widely separated than in the other species of the group. Upon these characters Allan Thomson has separated this species generically from Terebratalia. TEREBRATALIA GOULDII Dali. Terebratella gouldii Dall, Proc. Acad. Nat. Sci.

This species is thin with a weak hinge, a well marked “collar” within the foramen and no septal ridge; the teeth are normally propped. In the brachial valve there is a feebly developed cardinal process, the crural ridges are not united mesially, a very short low septum, almost entirely behind the muscular impres- sions which are very adjacent, receives the attachment of the loop some 5 millimeters in front of the beak in a specimen 28 millimeters high. In front of the septum are two short diverging raised lines about No. 2314. LIST OF RECENT BRACHIOPODA — DALE. 345 4 millimeters long which form the inner boundaries of the muscular scars.

This beautiful species grows to be nearly the largest of recent brachiopods and in form one of the most regular. In color it varies from a suffused rose color, to the variety miniata Gould, which is yellowish, painted with radial streaks of red. The oval form which Davidson described as T. bouchardi (var. b.) occurs rarely among the specimens I have seen. The shell figured in the atlas to the voyage of La Perouse by Lamanon, and which was called lamanoni by Schrenck in 1867, is not perhaps identifiable with anything, certainly not with the present species whose arched back could hardly have been ignored by the draughtsman, as it is characteristic of even the youngest specimens, and is responsible for the deep median sulcus of the pedicel valve. The foramen is large and the rugose deltidia not coalescent, sometimes meeting, and sometimes the gap between them is filled by an irregular calcareous plug. The teeth are strong, the props reduced to a pinpoint dimple in a mass of callus in the adults. There is a low ridge bifurcate anteriorly between the mus- 346 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 57. cular scars but not extending into the beak, nor attaining the pro- portions of a septum. The interior of the valve is marked by numer- ous radiating, bifurcating shallow furrows. The brachial valve is medially provided with a broad depression and produced to occupy the sulcus in the opposite valve; there is a strong bifurcate cardinal process; the sockets are not cross-striated; there is a thick mass of callus bridging the gap between the stems of the crura; the loop ex- tends nearly to the anterior edge of the valve. In this valve also a thick low ridge, grooved medially, extends from the callous mass between the crura forward between the thickened muscular scars. Out of the groove rises a very low thin short septum, the junction with the cross band of the loop is little elevated and slightly behind the middle of the valve. The interior of this valve is furrowed like the other valve. The shell is solid and tends to form callosities with age. It reaches a width of 53, a height of 52, and a diameter of 32 mm. TEREBRATALIA XANTHICA, new species. Shell bright yellowish-brown, transverse, inflated, smooth except for feeble incremental lines, the brachial valve feebly mesially exca- vated, but showing hardly any undulation at the anterior edge. The deltidia are coalescent in the young, widely separated in the adult, the adult foramen large, showing no “collar;” the props to the dental plates obsolete, no septum or mesial ridge between the muscular scars, and two short vermicular genital sinuses on each side. Brachial valve with no cardinal process, the crural stems separated to the apex, a short wide loop with a low short septum amd one genital sinus on each side. A young specimen which appears to be of the same species, however, has the crural stems united by a concave platform continuous with the posterior end of the septum which divides the space beneath the platform into two cavities.

I have some doubts whether the T. Icochii of Kuster, referred by Davidson to this species as a synonym, is identical. It suggests to me a discolored specimen of T. venosa Solander. I have never seen a specimen of the present species which agrees with Kiister’s figure. Sowerby figures a Magellania loop (fig. 32) which he, of course wrongly, refers to this species, and Reeve follows him under the name of T. globosa Lamarck. It is uncertain whether this is due to faulty drawing or to confusion with T. venosa. Carpenter identified L . erythraeus with this species and I followed him, but present studies have enabled me to correct this identification. In 1871 before Friele had made clear the modification of the loop in the course of growth I confounded shells in the analogous stages of Macandrevia cranium and the present species under the common name of Frenula jeffreysi. As I referred my species in my first announcement to the North Atlantic fauna, it follows that that name must be regarded as a synonym of M. cranium, and for the northern 350 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 57. and generally smaller variety of L. californicus Mr. Davidson's name of vancouveriensis must be used. The extreme variations in form of the variety vancouveriensis are very puzzling. Some of the specimens so nearly approach the L. morsei that it is only the presence of absolute gradations between them and the more usual ovate type that decides one to keep them distinct. Some specimens have a faint indication of uniplication in the brachial valve, others have the front edge straight but pinched together mesially as in L. blanfordi with a suggestion of bilobation, others again are frankly lenticular. Such differences in the same species throw doubt on the value of plication in these recent forms as a systematic character. The genital sinuses are threadlike and pro- duced nearly to the front margin of the valves. LAQUEUS ERYTHRAEUS, new species. Terebratula calif ornica Carpenter, Suppl. Rep. Brit.

The originally described form was almost bilobate, pinched together in the median line ; from this it varies to squarely truncate or even with the truncation prominent anteriorly. From rounded trian- gular it varies to ovate or even nearly circular, but always with the anterior truncation. Some specimens show a feeble “dorsal uniplication,” others have a marked depression medially in the brachial valve, and the most normal or typical show a pinching together of both valves in the median line with more or less biloba- tion. In the pedicel valve the teeth are strong, with well marked props which have a callous concave area between them, with no median ridge, but two widely separated low ridges which extend two-thirds of the way to the anterior edge of the valve; in the the brachial valve there is a moderate cardinal process, the crural stems are united by a concave platform supported medially by a strong septum separating the cavity below into two parts. The septum in front of the platform is thin, moderately high and extends forward less than one- third the length of the valve, the apex where the cross band of the loop is attached is about 4 millimeters in front of the tips of the crura, in a specimen 40 millimeters long. The color is always brownish. LAQUEUS MORSEI Dali. Laqueus morsei Dall, Nautilus, vol. 22, No. 3, July, 1908, p. 29.

Uanfordi hut larger, more inflated and with an anterior projection of the margin instead of the straight truncation visible in those varieties of Uanfordi which have not a medial sulcus. There is an extremely faint indication of a convex undulation at the front edge of the pedicel valve. The interior of the pedicel valve is much like that of L. blanfordi with three conspicuous genital sinuses on each side, rather broad and bifurcating near the margin. The brachial valve has an even shorter septum than Uanfordi, with two straight unbranched sinuses medially and one on each side with about four lateral branches which bifurcate near the margin. There is a hardly dis- tinguishable cardinal process. The deltidia are coalescent medially, and more or less wrinkled. LAQUEUS RUBELLUS Sowerby. Terebratula rubella Sowerby, Proc. Zool.

F 1 I have not seen any specimens of the typical pieties with the divari- cating irregular coloration, but I strongly suspect that L. rubellus Sowerby may be identical with it. The known range is the same. Davidson states that rubellus is distinguished from pictus by “its straight or slightly indented front.” He also says that the colors in the figure given by Sowerby in the Thesaurus are exaggerated. I have numerous specimens as bright as Sowerby’s figure, and while the front edge usually shows straight, there is sufficient variation to enable one to find numerous individuals of rubellus with a rounded front. However, I have no typical specimens of pictus and therefore I refrain from uniting them, but the question is worthy of careful examination. As far as I have been able to discover, Dillwyn was the first to give validity to Chemnitz’ name. LAQUEUS SUFFUSUS Dali. Laqueus suffusus Dall, Amer. Journ.

F 1 When I described this species I had no specimens of L. rubellus for comparison, and yielded to the opinion of Mr. Davidson, that it was a pale variety of L. rubellus , or as he afterwards concluded of L. 144382— 20— Proc.N.M.vol.57- -23 354 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 57. pieties. Now that I have a large series of both for comparison, I return to my earlier opinion and believe the two to be quite distinct specifically. Adult suffusus is about one-third the length of adult rubellus and is mainly of a pale gray color, with a very faint suffusion of red about the margin. The surface is dull, while rubellus in fresh state is polished, and it is impossible to believe that so expert a naturalist as Arthur Adams would have confounded the brightly colored rubellus with Macandrevia cranium.

Another variety, oblonga, is noted by Jeffreys in his collection, in which the shell is elongated and narrow, though still symmetrical; but this hardly exceeds the mutation to be observed in any large collection of a species of brachiopod. The type of this variety is No. 274186, from Finmark, but there are a number of other specimens among those catalogued under the general designation of M. cranium. MAC ANDRE VIA TENERA Jeffreys.

F 2 This like the other species of Dallina has a pedicel valve with a depression mesially, terminating in a protractive arcuation of the anterior margin, and two more or less obvious depressions in the brachial valve, with a medial low convexity between them or, as it has been called, “ dorsal biplication.” There are no props to the dental plates nor septum in the pedicel valve, the foramen is entire ; in the brachial valve there is a platform between the stems of the crura supported by a prominent medial septum. The cardinal process is short, wide, and feeble. There is more or less variation in relative width and strength of plication, but on the whole the species is very constant in its char- acters.

This differs from Magellania by the incomplete foramen, broad hinge area, and the presence of props to the hinge teeth in the pedicel valve. It differs from Eudesia by its incomplete foramen and broad hinge area, and from both by the heavy coarse structure of the shell. Type. — Terebratula grayi Davidson. PEREUDESIA GRAYI Davidson.

According to Tenison Woods the species is abundant on the south Australian coast but in Tasmania occurs only on the northern shore. Cat. No. Locality. Collector.

The young of this species are often smooth but can always be dis- tinguished from the young of M. lcerguelenensis by the entire foramen and produced beak. In the latter species the foramen is open from the beginning and the beak in the adult less produced and much more incurved than in M. jlavescens. There is often some uncertainty as to the accuracy of the localities for the shells of the United States Ex- ploring Expedition, for reasons I have explained elsewhere, so some doubt attaches to the specimens of undoubted M. jlavescens la- beled from Patagonia, now southern Chile, above cited.

This species ranges from Coquimbo, Chile, to the Straits of Magellan and the Falkland Islands. There is an interesting succession indicated, begiiming with the Tertiary Terebratella tehuelca of von Ihering, from the Cape Fair- weather beds, for which he proposed the generic name Pachymagas , and which retains the terebratelliform loop until of a very large size, but finally loses it and proceeds to a point where its cardinalia and adjacent parts and cardinal process are loaded thickly with callous deposits. The beak is also much prolonged and the foramen quite 364 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 57. entire. This is followed by T. lenticularis Deshayes, in which the loop becomes free from the septum much sooner, the beak is lower and the callous deposits in the adult, though exactly analogous to those of the fossil, are less abundant and crude; and finally the present species in which the beak is still lower and in some old specimens the foramen is not entirely closed, the loop becomes free of the septum at a still earlier stage, and the cardinalia never attain the callosified condition of its predecessors. I conclude from this that T. venosa , though lenticularis survives, is the newer development of the two. I suspect that the shell figured by Reeve as the original dilatata of Lamarck, which always has a large incomplete foramen and more transverse form, is a distinct species.

Bureau of Fisheries station 5172, off Jolo, Philippines, in 318 fathoms, sand; one specimen and a fragment. I have some hesitation in referring this species to Campages on account of the props in the pedicel valve (which Hedley does not refer to and are presumably absent in the C. furcifera), the divided cardinal plate and the projecting spurs of the lower part of the loop. Otherwise the resemblance is close. The closed aperture I presume is due to coalescence of spicules, but this demands more material to determine. Meanwhile attention may be called to its peculiarities by regarding it as a section of the genus. The specimen described was dead when dredged but retained the loop uninjured.

Magasella Dall, Amer. Journ. Conch., vol. 6, p. 134, 1870. Type. — Terebratula flexuosa King. Magellan Straits. The type upon which this group was originally based was supposed to be Terebratella evansi Davidson, 1852. A recent study of the material upon which my original diagnosis was based shows that the specimens really belong to the T. flexuosa of King, 1831. The confusion which reigned in the period just previous to and somewhat after the epoch-making discovery of Friele, in regard to the changes which take place in the form of the loop, during the develop- ment of the Terebratelloid brachiopods, was very great and affected all our synonymy. 368 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 57. It was not at first understood that certain species stopped short in their development at particular stages while others reaching that stage continued their evolution. In fact the confusion, or perhaps it would be better to say the doubtful points, are not yet entirely cleared up. Our series of Terebratella dorsata is quite small and perhaps should not form the basis of any dogmatic opinion, but from the material which has passed through my hands I feel confident that T. flexuosa King is distinct, adult, and not a stage of T. dorsata , as it has been sometimes regarded. In this opinion I am supported by the views of Davidson and Ihering. On the other hand T. evansi and T. valenciennesi, of which I have never seen authentic specimens, are admitted by Davidson and the majority of writers to be developmental stages of T. dorsata or some other similar species. Still another form, which by some authors is regarded as a muta- tion of T. dorsata , seems distinct, as I have already indicated under the head of T. sowerbii King. In 1891.1 I indicated the probable relations of the various small species of Magasella then known, and not much can be added even now, to that statement. The few species of doubtful relations will here be considered separately. MAGASELLA FLEXUOSA King. Terebratula flexuosa King, Zool. Journal, vol. 6, p. 337, 1831. — Sowerby, Thes.

The Magasella evansi is now believed to be its Magasella stage. The Waltonia may also belong here, but representing a still earlier stage of development, common to several species, it can hardly be posi- tively identified, though Mr. Davidson’s last surmise allotted it to T. rubicunda.

Quoy’s name is preoccupied by Leach; Sowerby's rubicunda by Solander in Donovan, hence we must take Sowerby's second name given to the immature shell, afterwards described by me as a Maga- sella. Quoy’s figure does not represent the attachment to the sep- tum of the descending loop but the cardinalia are accurately figured and there can be no reasonable doubt that this is the species intended. The Australian locality is unexpected and may be inaccurate, but was probably due to one of Stearns' correspondents. There is a feeble ridge in the pedicel valve hardly to be called a septum. There are no props to the hinge teeth. The foramen is normally entire but frequently open by reason of wear. The brachial valve has usually a prominent squarish cardinal process; a concave platform with a median ridge supported by a strong but low septum which extends to about the middle of the valve, which is retractively strongly uniplicate in some individuals, but not noticeably so in others, while still others have a number of additional minor plications.

The pedicel valve has a short beak with a large incomplete foramen a hardly perceptible median ridge internally, no dental props, and there are four slender genital sinuses, the inner pair widely separated, simple, bifurcate at the extreme ends ; the outer pair with five or six lateral branches on their outer sides. The brachial valve is very slightly retractively uniplicate. It has a small rugose cardinal process, a concave platform, supported medially by a strong low septum reaching to the middle of the valve, a loop well represented by my figure of 1870; the genital sinuses are LIST OF RECENT BRACHIOPODA — DALL.
