Clench Curator of Mollusks Museum of Comparative Zoology PRINTED AT BOTANICAL MUSEUM OF HARVARD UNIVERSITY CAMBRIDGE, MASSACHUSETTS 1945-1954 MERRILL E. CHAMPION THIS first volume of "Occasional Papers On Mollusks" is fittingly and sincerely dedicated to Dr. Merrill E. Cham- pion, who from the time "Johnsonia" and this present series came into being has quietly devoted himself to their suc- cess. In the capacity of Assistant Editor, his knowledge of the classical languages and his experience as an editor of medical journals has contributed greatly to the stature of these two publications. Dr. Champion was born in 1880 in Prince Edward Island, Canada, but moved to Massachusetts at the age of fifteen. He attended Boston Latin School and Wakefield High School from which he was graduated in 1898. He received his A.B. degree from Harvard College in 1902 and his M.D. from Harvard Med- ical School in 1905. He had a private practice for a short time and then attended the first class of the Harvard-Technology School of Public Health. Following this, he was a field director for the Rockefeller Sanitary Commission for the study and eradication of hookworm in North Carolina. In 1915, he was appointed a State District Health Officer and in 1918 he became head of the Division of Hygiene in the Massachusetts State Department of Health. His duties here included problems in child hygiene, communicable diseases, health education and editorial work. However, at the same time, this quiet, energetic man was teaching child hygiene at the Harvard School of Pub- lic Health as well as lecturing in the School of Public Nursing and the School of Social Work at Simmons College. In 1929, Dr. Champion was called to Michigan where he was in charge of setting up a health demonstration center in the Upper Peninsula. This work continued with great success until 1933 when activities were curtailed because of the de- pression. Though this was undoubtedly unfortunate for Mich- igan it was most fortunate for us as Dr. and Mrs. Champion [ iii 1 then moved to Cape Cod, Massachusetts where they Hved for several years. Here, his love of the sea and of the out-of-doors took him often to the beaches, and an absorbing interest in mollusks soon developed. He became a member of the Boston Malacological Club in 1935 and has been an ardent supporter of that organization since that time, serving as Conchological Recorder and President. One night at the regular club meeting he asked Dr. Clench if he might have a "square foot of space in the MoUusk Department where he might putter." He was assured that he would be most welcome in the department and that there would always be a desk for him. Little did anyone realize at that time what this was to mean to the department. When "Johnsonia" was started he immediately took on the duties of Assistant Editor including the indexing of the com- pleted volumes. In addition, he has revised completely the col- lection of North American land shells in accordance with Dr. H. A. Pilsbry's latest works. This was a tremendous task; not only was the main collection a very large one but there were in addition several thousand lots of unworked material which he has studied and which is now incorporated in the main collection. During the Second World War, Dr. Champion was again called to the State Department of Public Health and for four years worked only part time at the museum. However, he kept the editorial work going as well as his revisional studies on the North American land shells, and in 1943 he was made Research Assistant in the department. Dr. Champion has written numerous articles for medical journals and in addition to indexing "Johnsonia" has written a fine account of the life of Edward Sylvester Morse which was published in this series. Dr. Champion is far more than just a volunteer worker in the department, he is a friend and counselor to everyone, stu- dent and colleague alike, ready and willing to discuss all prob- lems and to help in every way possible.

More than one thousand titles on various studies appear each year, published in more than two hundred journals, museum bulletins or other publications. Our aim, in this present series, is to bring together in one publication a few such studies which are limited entirely to mollusks. Each number is an entity and may deal with any phase of malacology whether bio-bibliographic or monographic or it may consist of catalogues of families or genera. A con- venient number of pages will be grouped to form volumes, the numbers to run consecutively. Some of the studies covered in this volume resulted from problems that arose during other research. Others, such as the bio-bibliographic sketches, are part of a long range plan to build up a historic background in our field of mollusks. Such sketches serve a double purpose: to save documentary mate- rial concerning malacologists which is now available but which may eventually become scattered or lost entirely and to make known the location of type material upon which much of their work was based. We are dealing with a phylum of the animal kingdom which may have as many as 200,000 species. This number is, of course, an estimate only: even the approximate number will not be known for many years. Many regions, both sea and land, are still far from being fully investigated. Each decade highlights many new areas or new means of approach that result in additions to the known number of these beautiful and interesting animals. Just what the aqualung may do for the study of marine mol- lusks is anyone's guess, but in it we have a new aid that can be effectively used for investigating one of the richest and still [ xi 1 one of the most inaccessible areas of the sea— the rock and coral reef zone. Here, at varying depths, we have many mollusks that are seldom, if ever, cast up on the beach. This is also a region in which dredging has been only faintly successful. Not only will many new forms come to light, but, in addition, it may be possible to become better acquainted with the many rare species now recorded from only a few specimens. In this deeper water, mollusks can be studied in their own environ- ment, free from the vicissitudes of the intertidal zone— a place where the collector can observe them only during their most inactive period, mainly at low tide. The prospects ahead are exceedingly bright and even a novice in the field of biology can and very probably will make important contributions to our knowledge.

Indopijrgus was originally described as a subgenus of the Australian genus Potamopijrgus. It is raised at this time to generic standing. All members of this genus are small, less than 3 mm. in length; shell thin, ovate, smooth, with about 3 or 4 whorls, the last being large. Aperture sub-ovate, the lip slightly thickened. Umbilicus narrow and slit-like. Operculum, thin, corneous, paucispiral. Radula characters are distinct from Potamopijrgus. Rachidian tooth possesses two long thin basal wings and has a denticle 5 15 count of " . The lateral tooth oblique, with a strong o-o central elbow. The denticle count varies from 4-1-6 (nevilli) to 3-1-5 (bonnei). hidopyrgus is placed in the subfamily Hijdrobiinae. Other species placed in this genus are /. mous- soni Issel 1874 and /. bonieensis Issel 1874, both from Bintulu, Sarawak, Borneo. Though this genus has never been implicated as an inter- mediate host of the human blood ilukes, there is a possi- bility that it may be found to be a carrier of schistosome cercariae, as in the case of its relatives, Schistosomophora and Katayama.

Charles Bonne, legit. 1941. Remarks, This tiny freshwater shell is common along the shores in certain parts of Lake Poso and Lake Lindoe, in the Celebes. It should be suspected as a possible carrier of schistosome cercariae. The shells from Lake Poso are more mature and hence a bit larger than the specimens from Lake Lindoe. In nature the shells are partially covered by a thin encrusting of lake slime. This species differs from nevilli Thiele in having a more extended spire, vv^horls of the spire more convex and a color line of deep chestnut brown around the lip. hidopTjrgus borneensis Issel is con- siderably more squat than any of the other species and differs, like /. moussoni Issel, from bonnet and nevilli in lacking the continuation of the lip across the parietal wall.

Adult shell about 4.5 to 6 mm. in length, elongate-ovate, thin, color a translucent chocolate brown to light brown (often covered by black pond slime), with a thin, very dark brown color line around the peristome or entire mouth border. Nuclear whorls (developed in egg mass) two in number, rounded, glassy, appearing minutely granulated under magnification. Postnuclear whorls (developed after hatching) regularly increasing in size, rounded, with the body or last whorl more than 3/5 of the total length of the shell. Extremely fine axial sculpture of slightly retractively slanting lines of growth. Spiral sculpture seldom visible. Suture between whorls well indented. Base of body whorl short, rounded, with a nar- row, slit-like umbilicus. There is a slight thickening of the outer lip just behind the aperture into a callus or weak varix. Aper- ture broadly ovate, slightly expanded, slightly reflected. Pari- etal wall slightly glazed. Interior of aperture light chocolate brown. Periostracum absent. Operculum very thin, transpar- ent, paucispiral with eccentric nucleus and two to three whorls. Scar of muscular attachment about half the area of the oper- culum. Animal (Plate 3, figs. 1-6) small, with a simple foot, underside of which is broad and short, rounded behind and truncate in front. Anterior edge of foot with a narrow, fairly deep mucous slit. Foot often carried in life with a longitudinal fold of flesh along the midline of the side of the foot. Head relatively small. OCCASIONAL PAPERS ON MOLLUSKS Plate 2.

(Explanation of plate on opposite page.) OCCASIONAL PAPERS ON MOLLUSKS 9 proboscis or snout blunt, short, bilobed in front. Single tentacle on each side of head simple, slender, swollen at the base where the eye is located. In male specimens, the verge or penis is lo- cated well behind the head on the dorsal side of the body and on the midline. It is far enough back to be obscured by the mantle. Penis simple with a single functional spermduct, trans- lucent yellowish, slightly flattened dorsally, rounded ventrally and tapering gradually towards the rounded distal end, carried in a sinistral, single-coil position. Mantle thin with a slightly thickened border. In females the mantle border just opposite the "vaginal" opening is capable of being puckered into a funnel-shaped notch. Color of animal in general a dark blackish gray. The most distinguishing color markings are the bright splotching of yel- low, granular-like dots over each eye forming false "eyebrows." In detail: underside of foot gray, peppered with minute white dots. Sides of foot and body grayish with a heavy suffusion of minute black dots. A few yellow or white dots are sometimes present on the sides of the upper body and dorsal side of the forefoot. There is a suffusion of white dots on the inside of the mantle opposite the anal and "vaginal" openings. Eyes jet black with a tiny clear lens. Proboscis sandy gray-black with a red- dish tinge caused by the buccal "cartilages" inside. Interior of mouth at the anterior end of the proboscis reddish. During feeding, the glint of the glass-like teeth of lingual ribbon or radula may be seen. Tentacles translucent gray intermingled with tiny gray dots. The feces of healthy animals are small, compact, hen's egg in shape, and may be seen through the shell lined up in the rectum in the last two or three whorls. Under a bright light and magnification, the edges and folds of the body and foot give off a beautiful metallic blue sheen. Plate 3. Fig. 1. Side view of living animal with shell removed in drawing.

Variation in shells is considerable in several characters in adult specimens from the same locality, nearby localities and distant localities on other islands. Measurements of the num- ber of whorls, length and width of shell were made on twenty or more specimens from eight lots (5 specimens only from Suri- gao) with the following results: (largest shells length 6.4 mm.; width 3.2 mm.). Locality Whorls Length Width Length divided average average average by width number (average) Surigao, Mindanao 5.8 5.7 mm. 2.8 mm. 2.03 Jabonga, Agusan, 6.4 4.8 2.5 1.92 Mindanao Palo, Leyte (1935) 6.2 4.7 2.5 1.88 Palo, Leyte (1945) 6.1 5.0 2.4 2.08 Dagami, Leyte 6.3 4.9 2.7 1.81 Calbiga, Samar 5.9 4.3 2.4 1.79 Naujan, Mindoro 6.4 5.0 2.5 2.00 These differences indicate that this species varies in stout- ness and length with little or no correlation with its geograph- ical distribution. After adequate field study, it may be found that local ecological conditions are responsible. Other varia- tions of the same nature include size of lip thickening or varix, predominence of minute axial sculpturing, thinness of shell, shape of operculum, and number of whorls in the nucleus of the operculum. There is no sexual difference detectable in the shells of five females and three males examined. Radula. The lingual ribbon or radula is situated in the buc- cal cavity in close association with the buccal cartilages. There are about 70 rows of teeth on the ribbon which is held together by a thin, transparent membrane bearing two side wings (Plate 4, figs. 2 and 3). Each row consists of a single rachidian (or central) tooth flanked closely on each side by first a lateral (or median) tooth, then an inner (or first) marginal and lastly by an outer (or second) marginal tooth. Each tooth bears a char- OCCASIONAL PAPERS ON MOLLUSKS 11 acteristic number of tiny denticles. Radula counts in this paper refer to the number of denticles on each tooth. The usual count on the rachidian tooth for this species is two small denticles on each side of a single large denticle on the top edge of the tooth and three small basals on each lower side (written thus: ^-^' (Plate 4, fig. 1). A study of every tooth on several ribbons revealed a varying frequency in the denticle counts. From anterior end of ribbon to the posterior growing end, the variation in the upper or front edge of the rachidians were: first 10 teeth, 2-1-2; next 6, 1-1-2; next 2, 2-1-2; next 7, 2-1-1; next 13, 2-1-2; next 7, 2-1-1; last 20, 2-1-2. The basals varied from 3-3 in the first half of the ribbon gradually to 2-2 in the last half. Lateral counts 2-1-3 mostly, a few 1-1-3, a few 3-1-3. Inner marginal tooth 9 mostly, some 8. Outer marginal 7, 6 mostly, a few 5. It is evidently unsound to create species or genera, at least in this group, on the basis of denticle counts which vary as much as they do. Chinese workers have found this same type of radula variation in Oncomelania and Katayama. Plate 4. Fig. 1. Radula (left to right: rachidian, lateral, inner marginal, outer marginal).

The gills stretch across the man- tle only as far as the rectum which is also welded to the man- tle. The lamellae extend up on the mantle for a short distance and then flatten out into indistinct filaments or para-ctenidial folds which are closely welded to the mantle (Plate 3, figs. 5 and 6). The pharynx in the proboscis contains two, paired flatfish buccal "cartilages" tinged with a reddish brown pigment (slightly visible externally through the wall of the proboscis). Salivary glands sac-like, paired and lying along the sides of the oesophagus with the ducts leading forward and into the pharyn- geal cavity. The oesophagus leads back into the body and joins the stomach which is in the posterior part of the body whorl. The brownish spotted hepato-pancreas or " liver" extends from the apical (tip) region of the shell down to the penultimate whorl. The rectum, after passing down through the last four whorls (paralleling the uterus in females) comes forward fused to the right side of the mantle. The bean-shaped pericardial sac or heart in the body whorl contains the auricle and ventricle. The central nervous system (Plate 5, figs. 1 and 2) is strik- ingly similar to Robson's figure (Ann. Mag. Nat. Hist. (9) 8, p. 401) of Katayama nosophora Robson, differing only in having a long and slender supra-intestinal ganglion (as in Heude's figure of Oncomelania hitpensis Gredler. Mem. Hist. Nat. Emp. Chinois, 1), three instead of four labial and ocular area nerves arising from the antero-dorsal area of each cerebral ganglion, and a pair of small nerves arising dorsally from each of the para- and pro-podial ganglia. The inner labial nerve splits in two not far from its cerebral ganglial origin, unlike in Kata- yama and similar to Oncomelania. Only scanty information is available to date on the eggs of Schistosomophora qiiadrasi Mlldff. A single, small egg and a clump of four eggs have been seen under aquarium conditions. Habitat and Habits. Amphibious, remaining out of water for long periods of time attached to moist, shaded grass, banks of ditches, wooden pilings, and in the area of rice fields. Prefers water of a slightly acid pH. Early Japanese workers found that OCCASIONAL PAPERS ON MOLLUSKS 13 specimens of Katayama nosophora Robson were killed in a one per cent solution of lime in 24 hours. In the Katayama District of Japan, 75 to 85 ^c of the snail population was eliminated in a O.l^c solution of lime. Copper carbonate would be effective in small ditches and ponds. The animal is a continual browser in and out of water, and has a tendency to move upwards out of water. The mode of locomotion is in the form of a sliding, not loping, motion. Trematode Parosiie. Schistosomophora qiiadrasi was first implicated as the intermediate host of Schistosoma japoniciim Katsurada in 1932, by M. A. Tubangui (Philippine Journ. Sci., 49, pp. 295-304, pis. 1-5). Subsequent workers from 1934 to 1945 have substantiated this discovery. Until 1945 no other species of snail has been known to be a vector of this disease in the Philippines. Locality Records.

Wading birds might possibly be a mode of spreading this spe- cies, since the animal is able to withstand weeks of desiccation and might by chance be carried adhering to the feet of waders. Nomenclature. Rensch recognized in a brief note (Philippine Journ. Sci. 50, 1933, p. 325) that his Oncomelania hydrobiopsis of 1932 is identical with Prososthenia qiiadrasi Mlldff. Bequaert in 1934 concluded on the basis of paratypes of P. qiiadrasi Mlldff. in the M.C.Z. collection that O. hydrobiopsis Rensch was a synonym. Two years later, Bartsch maintained the two species were distinct on the basis of a single, stout paratype and on the basis of a difference of one denticle count on the outer marginal radula. That specimen is found now by Bartsch to fall well within the limits of variation of the specimens from all four islands. A discussion of generic position or generic validity is not 14 OCCASIONAL PAPERS ON MOLLUSKS Plate 5. Central Nervous System. Fig. 1. Right side view. Fig. 2.

Note on Identification Proper identification of the snail intermediate host and a greatly increased knowledge of its geographical distribution are highly important, as schistosomiasis is endemic only in places where the mollusk is found. In the Philippines the snail host can be confused with a small land mollusk, Lamel- laxis (Allopeas) gracilis Hutton which has no operculum, and with young melanid snails which have beautiful, heavy sciilp- tiiring on the early whorls. Every effort is being made by malacologists to render quick identifications as accurately as possible.

There can be no doubt that this figure corresponds to shells from Australia and the East hidies which 29 30 OCCASIONAL PAPERS ON MOLLUSKS are in the collection of the Museum of Comparative Zoology. Many early authors mistook the figure for that of Papyridea hiatus Meuschen which is a Western Atlaniic species.

Cardium rackettii 'Donovan,' Hedley 1916, Proceedings Linnean Society of New South Wales, 41, p. 685. In 1916, C.Hedley published an article in which he suggested that the real C.tenuicostatum Lamarck had been "lost to view" and that the later Australian references should be transferred to C rackettii Donovan. We cannot accept these suggestions, since we find shells from Australia that agree with Lamarck's type figure in Delessert. Hedley pointed out that Lamarck had described a specimen measuring 56 mm. in height. Our largest specimen reaches 51 mm. It is possible that there was a mis- print in this particular, as the remainder of the description agrees with the shell in question. Hedley also mentioned that his shell had 49 ribs, while the Lamarckian species had but 48. Such close differentiation does not hold in the family Cardiidae, where there is often a variation of 3-4 ribs. Reeve reported that there was a variation of from 40-52 in the rib count of C. tenuicostatum Lamarck. We suggest that the name Fulvia tenu- icostata Lamarck be retained for this Australian species. Acanthocardia spinosa Solander Cardium spinosum Solander 1786, Catalogue of the Portland Museum, p. 105, lot no. 2297 refers to Favanne, La Conchyliologie ou Histoire Naturelle des Coquilles de Mer, d'Eau Douce, Terrestres et Fossiles par M.

It is unfortunate that we must discard the well known name of Cardium hians Brocchi due to a prior use by Spengler. Lamarck described Cardium indicum as the "recent analogue" of Brocchi's C. hians, which had been described from fossil material. We consider the two to be synonymous thus ena- bling the use of Lamarck's name. Lophocardium cumingii Broderip Cardium cumingii Broderip 1833, Proceedings of the Zoological Society, Lon- don, p. 82, 83; Reeve 1843, Conchologia Iconica, 2, Cardium, pi. 12, fig. 59 (Gulf of Dulce, Costa Rica, Central America, in 12 fathoms). Protocardia {Lophocardium) cumingii "Sowerby" Smith 1944, Panamic Ma- rine Shells, Winter Park, Florida, p. 58 [Protocardia comingi, fig. 738 error in reference to figure]. The original and unique specimen of Lophocardium cumingii Broderip was collected by Hugh Cuming and is in the British Museum. Recently, through the courtesy of John Armstrong of the American Museum of Natural History, we have been privileged to study specimens of this shell dredged by the As- koy in 194L They were taken at a depth of 17-21 fathoms in Ardita Bay, Colombia. This is a very rare and beautiful shell, about 25-30 mm. in length, inflated and gaping. We can add little to the enthusi- astic description of Broderip, who said, "This beautiful bivalve, rosy, transparent and exquisitely wrought, was found by Mr. Cuming whose name it bears." It is fragile and delicate, rose- pink and iridescent. There are many fine radiating ribs, ap- proximately 200, crossed by faint, irregular lamellae which become slightly more developed and more widely spaced on the anterior slope. There is an unique vertical ridge, made of 32 OCCASIONAL PAPERS ON MOLLUSKS periostracal material which is formed in elaborate loops and gives a crest-like appearance. This rib separates the posterior sculpture from that of the anterior slope of the shell. It is not made of shelly material as in the case of Madra alafa Speng- ler. Because of this vertical ridge, Fischer (1887, Manuel de Conchyliologie, p. 1038) allocated C. cumingii to a section which he named Lophocardium and placed in the subgenus Papyridea Swainson. Fischer's description is brief and he differentiates the shell section on only the basis of the "vertical ridge with a prominent wing-like" shape. There are species of the genus Fidvia that have looped periostracum; there is also a species of the genus Microcardhim having a vertical ridge made up of periostracum and separating the posterior sculpture from that of the anterior slope. There is another, more significant basis for differentiation, however. This is the fact that Lophocard- ium has no anterior lateral teeth. The cardinal teeth are well developed, the posterior are long and narrow, but there is no trace of the anterior laterals. Because of this unusual hinge character and the differences in the sculpture already men- tioned, Lophocardium should, we believe, take its place as a full genus. There are two species of the genus Lophocardium which have been dredged in the same general locality, L. cumingii Broderip and L. annettae Dall. The latter was reported in 1889 (Nautilus 3, p. 14; Report of the Albatross Mollusca, Proceed- ings of the United States National Museum, 1889, 12, pp. 264- 266, pi. 10, fig. 4) from the Coast of Lower California near Cerros Island, Mexico. Lophocardium annettae Dall is slightly higher, not so elongate posteriorly and is more inflated than L. cumingii Broderip. It is less fragile and less highly colored, having only a pinkish tinge. The outstanding difference, how- ever, is the arrangement of the periostracum on the posterior slope, which is in a very definite pattern of from five to seven concentric ridges, running parallel to the growth lines. .^y Occasional Papers On Mollusks K U 19 6 *" I'ublislied by *V/ The Department of Mollusks ^ '^^i-*^ Museum of" Comparative Zoolooy, harvard Lni\ersity -"^ Cambrici SlegMond doyt of grevth etc COUNT FHOH ONf COCONUT HUSK LCTTt. »HILlPPIHCt Plate 9.

When the embryonic snail is ready to hatch, on the fifteenth day, it has produced U to lif whorls (fig. 4). The development of the snail is graphically repre- sented in Plate 9, fig. 6. During early and middle stages of development the embryo revolves slowly, end over end, in one direction, as is the case with most gastropod veligers. This action is not continuous, but more frequent in the final stages and is accomplished by the action of exceedingly minute cilia on the underside of the foot. A few days before hatching, the embryonic snail is restless and often moves its head and foot in and out of the shell. The jaws and radula (ribbon of teeth within the proboscis) begin to function. The sand capsule is usually eaten away when the young is ready to emerge. Crawling and feeding begin at once after hatching, and within 12 hours after birth the young snail will have produced enough fecal material to equal its own bulk. Motion and a yellowish color are characteristic of life throughout embryonic development. Dead embryos may be detected by the absence of motion and the presence of a milky- white color. Several eggs in situ on pieces of coconut husk were dried in the laboratory at room temperature (84° F.) to determine the effect of desiccation. All of the eggs were alive after a period of 12 hours. However, under the same conditions, 10 (83%) eggs were dead after 48 hours of drying. Desiccation for 12 hours under artificial light at a temperature of 108° F. killed 10 (100%) eggs. Direct sunlight would probably kill eggs in an even shorter time. Figure 6 graphically represents the results of an inspection of a coconut husk taken from Gacao Creek, 1 mile southwest of Palo, Leyte. The husk was found in two inches of water hidden in the tall, shady grass of the creek bed. All egg cap- sules were removed, opened, and recorded according to the amount of embryological development. Of the 100 eggs re- moved, 14 were found to contain dead embryos. The graph shows two peaks, one occurring at an early cleavage stage, the other at a much later stage of development, two or three days from hatching. Four days previous to taking the husk from the creek, rains had fallen for 24 hours and the level of the OCCASIONAL PAPERS ON MOLLUSKS 45 water in the creek had risen a foot. This would seem to indi- cate that soon after the occurrence of a heavy rain and rise in the level of water, females began to lay eggs more actively. The second peak represents a much earlier spurt of egg-laying, approximately 14 days previously. About 20 empty capsules with their tops punctured were found on the husk. In addition to this, it was noted that there was an increase in the number of newly hatched snails in the surrounding colony of snails. This phenomenon has been observed several times following a rise in the level of water in the creek and it is likely that the current of water aids in the release of young snails from the capsules. This may also account for the drop in the number of snails in the last stages of development (15 days) shown in the graph. Egg counts on sticks, old boards and other coconut husks in the same creek showed similar peaks but not at the same stage of development. This is to be expected, since egg-laying is governed by the amount of water in the immediate area of the husk, and not directly by the rainfall. In Gacao Creek, the de- gree of moisture or amount of water varies a great deal even in spots less than twenty feet apart. It is quite possible that fully developed embryos ready to hatch do not break out of their capsules until the arrival of favorable flood periods which occur two or three times a month during the summer. Measurements of snails of all ages in a colony show peaks in the size of individuals in the population and these peaks indicate that the times of hatching are un- evenly spaced. Such peaks most likely represent previous rainy spells that aided hatching. Seasonal increase in egg-laying on the island of Leyte is as yet undetermined, but it is likely that during late October, November and December, when there is an abundance of rain and overcast skies, there is an increase in mating and egg4ay- ing. This type of small, single, sand-jacketed egg is common to the members of the genus Oncomelania. The egg of O. noso- phora Robson (syn.: Katayama nosophora yoshidae Bartsch, K. Hi Bartsch, K.faiisti Bartsch, K. cantoni Bartsch) was first dis- covered by S. Sugiura (1933) in Japan. Of them Sugiura says, "The eggs of this snail are usually laid singly and they are en- 46 OCCASIONAL PAPERS ON MOLLUSKS tirely covered with a layer of mud particles, which is inciden- tally attached to the outer mucous shell-membranes, so that they look like small grains of mud or sand." His remarks and clear illustrations parallel our findings in O. quadrasi Mlldff. of the Philippines. Fu-ching Li (1934) published a figure of what he then believed to be the eggs of the ribbed Oncomelania hupensis Gredler of China. Those were probably the eggs of some Planorbid snail, for the next year (Li, 1935) he corrected this error and de- scribed and figured eggs of O. hupensis which are identical to those of O. quadrasi and O. nosophora. Bartsch in 1936 over- looked this correction and published the incorrect drawings of O. hupensis eggs. Li's manuscript drawings of the eggs of Katayama Hi Bartsch (= O. nosophora) included in the same paper (Bartsch, 1936) are the same as the eggs of the Japan- ese and Philippine species. Under adverse or aquarium conditions Oncomelania will sometimes lay eggs without adding a sand jacket. A study of the anatomy, shell characters, ecologic variations and radulae of living specimens of Chinese, Japanese and Phil- ippine Oncomelania has led the author to the belief that the genera Schistosomophora Bartsch and Katayama Robson are synonymous with Gredler's genus, Oncomelania. All known species of Oncomelania, including O. formosana Pils. and Hi- rase, possess a characteristic yellow ''eyebrow" or streak of yellow color granules embedded in the skin just above the eye. Nine months' search in the field in the Pacific and China has failed to bring to light any other freshwater snail with this character. OCCASIONAL PAPERS ON MOLLUSKS 47 New Localities For Oncomelania quadrasi Mlldff. During the author's four-month survey for snails in the Phil- ippines, a number of new localities harboring Oncomelania quadrasi Mlldff. were discovered which seem worthy of re- cording at this time. In the following list of new Philippine localities, the percentage of snails infected with the cercariae of Schistosoma japoniciim Katsurada followed by the number of snails examined are included in parentheses. In cases where no figures are given, the snails were not examined for cercariae. Leyte Island L San Isidro, 4 miles E.N.E. of Dagami, 2 miles north of the Binahaan River. June 17, 1945, (lO^c-lO). 2.

Though the snail has not been found on any island of the Philippines other than the four previously known to harbor it (Leyte, Mindanao, Mindoro and Samar), the new localities re- cently discovered indicate that there may be a much more general distribution of this snail than was formerly supposed. Therefore, it is not unlikely that it will be found on other is- lands of the Philippines in future surveys. It is important to note that although no human cases of schistosomiasis have been reported from Lake Lanao, Minda- nao, the recent discovery of the intermediate snail host in this area serves as a warning of possible future outbreaks of the disease.

Turner John Gould Anthony, son of Joseph and Mary Gould Anthony and first assistant in charge of mollusks at the Museum of Comparative Zoology at Harvard College, was born in Provi- dence, Rhode Island, May 17, 1804. Regarding Anthony's child- hood we know very little except that at an early age he devel- oped an interest in natural history and, while living in Provi- dence, was mainly interested in marine shells. Although at the age of twelve he was forced to leave school and earn his own living, he continued his interest in natural history and educated himself in the field of mollusks. In 1832 Anthony married Ann Whiting Rhodes of Providence and two years later, with other members of the Rhodes family, moved to Cin- cinnati, Ohio. The records show that Anthony held several positions while in Ohio, the first with Allen, Rhodes & Com- pany, Silver Plate Manufacturers. In 1840 he was listed as an independent accountant. Four years later he was working with Derby Bradley & Company into which firm he was later taken as a partner; by 1849 the company was known as Bradley and Anthony, Booksellers and Publishers. There are several pub- lished notes to the effect that Anthony worked in a bank but no definite record of this can be found. Shortly after Anthony's arrival in Cincinnati he was elected to membership in the Western Academy of Natural Sciences, and, throughout his stay in Ohio, he was an ardent supporter of the struggling young Academy. He held the offices of sec- 81 82 OCCASIONAL PAPERS ON MOLLUSKS retary, librarian, and curator on various occasions and the meetings were often held at his home. He soon became the local authority on the fossils of the Blue Limestone of Cincinnati. The varied forms of our midwestern terrestrial and fluviatile shells also attracted Anthony's atten- tion and he rapidly built up a fine collection, specializing first in the Unionidae and later in the Pleuroceridae. By 1839 he was carrying on a very active exchange in the hope of as- sembling a complete collection of North American shells. In 1847 his health and eyesight were seriously impaired after contracting scarlet fever from his youngest daughter, then two years old. His son wrote that "for two years he was unable to see his hand in front of his face and it was seven years before he was able to return to business." We have come across nu- merous references to Anthony's eye trouble as it affected both his business and scientific life. In 1849 Anthony sent the descriptions and specimens of six- teen new species of Melania to Dr. A. A. Gould at the Boston Society of Natural History for publication in the Proceedings of that Society. Later, in a notebook containing an annotated collection of his papers he wrote the following: '' My vision at that time being very much obscured owing to a disease of the eyes, could not be fully depended upon for nice discrimination in regard to species, and Dr. Gould was requested to examine and compare the specimens forwarded, making such correc- tions and additions as his better vision and more extended means of comparison might suggest, so that the descriptions when published might be as complete and perfect as possible. To some extent this was done." On the label of the type speci- men of Melania brevispira, which was described in this paper Anthony wrote: "determined by touch alone while I was blind." In June 1853, in an effort to restore his health and to further his study of fresh-water shells, Anthony made a walking trip from Cincinnati, Ohio through Kentucky and Tennessee to Macon, Georgia. Anthony's notes, letters and original labels have added but little to his published record of the trip and though several people have tried to follow Anthony's route it has been practically impossible. The following note given to me by William J. Clench concerning his attempt to cover Anthony's route is of real interest here. " During the summer OCCASIONAL PAPERS ON MOLLUSKS 83 oX£j(j^.aia W^ 1804-1877 Plate 15. From an original photograph copied by F. P. Orchard 84 OCCASIONAL PAPERS ON MOLLUSKS of 1924, P. S. Remington and I attempted to follow the route of Anthony from Cincinnati, Ohio, at least as far south as Chattanooga, Tennessee. This, of course, was only part of a program, outlined by Calvin Goodrich of the University of Michigan, for a general reconnaisance in Kentucky, Tennessee and northern Alabama for future river surveys of the mollusks in these states, mainly for Pleuroceridae. Anthony had left but little data behind for us to go upon. He had listed his new spe- cies only by states, and not in the form of specific localities. Old maps were consulted for roads that may have been fol- lowed between the larger cities. Our attempt was to collect at all creeks, rivers and springs along the way. We were fortu- nate in collecting many of the species of Anthony, probably at the type localities or at least in the same streams that he had visited many years before." Due to lack of proper precautions in caring for his collec- tions in the field, Anthony, on returning home, apparently had a rather serious mixture of lots (Goodrich 1931). However, in going over many of his notes and original labels we have found references to specific localities as well as discrepancies be- tween the data given on labels and those published. This ad- ditional material has been included in square brackets under the proper species in the catalogue accompanying this paper. On returning from this trip Anthony was still unable to work except for occasional bookkeeping, apparently done at home. This period must have been one of great difficulty for the Anthony family, for his sons, Thomas and Edward, both left school in order to help support the family. In a letter to Thomas Bland, Anthony wrote, " During my troubles my shells were my mainstay on every occasion. To use my friend's language ... . T had enjoyed the pleasure of collecting my shells, the satisfaction of looking at and studying them when collected, and now I am eating them,' which in my case was true, since when my funds ran low and I could earn nothing I literally sold my shells to procure bread — and a good source of income it was too — 2 or 300 dollars at a time did I sell of shells and fossils — many of my chosen specimens were sacrificed which I may not soon replace and my library too followed suit. . . ." However, even this was not enough and in 1856 Anthony wrote E. R. Mayo that he was "over head and ears in business at last OCCASIONAL PAPERS ON MOLLUSKS 85 trying to make my bread and butter, after so long eating upon the small stock I had previously made - to tell the truth I had about found the end of my string and it was a work of neces- sity to do something more substantial than work over shells and collect specimens." Anthony was at this time with Taylor and Anthony, General Insurance Agents. He continued in partnership with Taylor until he left Ohio to become assistant in the Museum of Comparative Zoology. Anthony collected all species in large quantities and ex- changed with conchologists throughout the world. Many of his species he named and sent out on exchange before the de- scriptions had been published. Consequently many of the spe- cies which appear in Reeve's Conchologia Iconica, though iso- lated by Anthony, must be credited to Reeve. In most cases Anthony never did publish descriptions of these species, but a few species sent to Cuming, Anthony later described and pub- lished Reeve, however, having access to the Cuming collection also described them, crediting them to Anthony. Since Reeve's monograph came out a few months before Anthony's paper, the credit must go to Reeve who fortunately did not change any of Anthony's manuscript names. In Brot's catalog of the Melania (1862) there are two Anthony names which do not ap- pear elsewhere and which were apparently undescribed species sent to Brot. This is also the case with Melania obliqua listed by Try on as a synonym of Melania incisitm Lea. In 1852 Temple Prime wrote Anthony concerning his proposed mono- graph of the Corbiculidae, asking for material on old and new species. Anthony immediately responded by sending the de- scriptions and specimens of several new species of Cyclas and Pisidiiim which Prime published and credited to Anthony as was the accepted procedure of the day. However, according to the International Rules of Zoological Nomenclature, the per- son who publishes the species is the one to whom the credit for the name must go. All species, so far as can be determined, which have been credited to Anthony but published by others have been included in the following catalogue. In many of Anthony's letters he refers to the K K's, very probably a conchological club, an association of correspondents with whom he had exchanged through the years. His "King" of the KK's was Hugh Cuming with whom Anthony had many profitable exchanges. 86 OCCASIONAL PAPERS ON MOLLUSKS When Spencer F. Baird became Assistant Secretary of the Smithsonian Institution, he immediately tried to build up the collections and asked all zoologists to contribute. Printed labels were supplied collectors by the Smithsonian Institution, and Anthony on receiving those prepared by Lea for the Unios was incensed. The following quotation is a portion of a letter writ- ten to Baird in which he complains bitterly concerning the practice of that time of claiming authorship of a species by merely changing it to a different genus. Unfortunately this practice was continued until about 1900. Office of Taylor & Anthony, General Insurance Agents, 76 West Third Street, Cincinnati, July 24th, 1860 Spencer F. Baird Esq. My dear Sir: I wrote you respecting labels for the Unio's designed for the Cabt. of the Smithsonian Institution and have since rec'd a set of the labels in question, but on examining them I find them most extraordinarily defective, particularly in regard to species which I have taken great pains to prepare for the Collection. About One hundred Names of well known species have been entirely omitted altho' they are such as generally form the basis of exchanges & many of them are superseded it seems by names of Mr. Lea's which are at best only entitled to rank as synonyms — Now it seems to me that the only fair & honest way to print a Catalogue of American Unionidae is to adopt the plan pursued in some other parts of the General list, viz to include every species published by various Authors leaving the synonymy to be worked out by each one as he sees fit, or if there must be an expurgated list, for heaven's sake intrust it to unprejudiced & disinterested hands to be arranged with at least the appearance of honesty and justice— If this list is to be made the Authorised & only Authorised list, why I have not the slightest hesitation in saying that I for one cannot con- form to it and if the shells for your Collections must be labelled by it, some one other than myself must do it, for I cannot rec- OCCASIONAL PAPERS ON MOLLUSKS 87 ognize a list so manifestly incorrect and govern myself by it in naming my specimens— After pursuing the study of Con- chology for 35 years during all which time I have been engaged in numerous and large exchanges and for 26 years past having distributed Annually many thousands of Unio's under their true names I cannot consent at this late day to abandon them merely to minister to the inordinate and insane Ambition of Isaac Lea, to be considered the only American Conchologist— And how will our transatlantic Naturalists regard such a pub- lished list purporting to be a Complete list of American Unioni- dae when they find it ignoring such names as Unio crassus Say, U. heros Say, U. politus Say, U. lapillus Say, U. cicatri- cosus Say, U. nexus Say, U. metallicus Say, U. subrostratus Say, U. glebulus Say, and U. purpureus Say, all well known names. True Mr. Lea is very careful to include U. complana- tus Lea which he says is the same as U. purpureus Say, which name of complanatus he contends should supersede it because Solander had a "My a complanata" & he endeavors to show that Mya c. was intended to represent our Unio purpureus hence he transfers it to ''Unio" & thereupon proceeds to ap- pend his own Name as author without ever describing it & robbing thereby both Say and Solander at one Operation. Prof. Rafinesques Names with the single exception of "Metanevra" are entirely set aside to make room for Mr. Lea's subsequent christenings— & such names as "torsus" "costatus" "flavus" & cardium, with some 30 others must all be passed by as un- worthy of notice because Mr. Lea affects not to understand them — Now Mr. Lea May print as many such Catalogues & synopses as he pleases and every one he has printed has varied from its predecessor according to his fancy for the time, and I would say nothing, but I do not like to find the Smithsonian Institution lending its influence to Circulate any such errors— I speak freely and warmly too, because I feel it — I have during the 26 years I have exchanged Unio's distributed more speci- mens than any other living Man — they are in all the foreign collections private & public. My names are such as long in- vestigations proved satisfactory to my mind, and reputation even as a Nomenclator is dear to me, far too dear, to be taken away in this manner even by implication. I do not wish to be forced to speak of this Catalogue to my Correspondents Abroad 88 OCCASIONAL PAPERS ON MOLLUSKS as in justice to myself I shall be compelled to if no correction is made in it -A supplement should at once be published con- taining the rejected list of Names & thus some little justice be done such Authors as Say, Conrad, & Rafinesque who are at least equal to Lea, however much he may endeavor to produce a contrary impression. One other Grand Error in the Catalogue is in the Margari- tana where Mr. Lea unhesitatingly places his name as author to 25 out of the 26 species enumerated, while the fact is that he never described more than 16 of the whole number— how ridiculous to place his name to a shell which was named al- most before he was born, as in the case of M. margaritifera— Mr. Lea's only claim being in Consequence merely of his hav- ing so placed them in a Catalogue as ''Margaritana" instead of "Alasmodon" a very cheap way of attaining authorship truly & tomorrow somebody else may transfer the entire lot to some other Genus and claim the authorship in like manner in his turn — how much easier this is than troubling oneself to describe a species—'' Authorship made easy'' with a vengeance — Mr. Lea in this way has his name printed as author to one species which he at the same time confesses he has Never Seen! ! ! how much further can absurdity go— In Anodonta Mr. Lea claims two species at least which he never described viz A. edentula & fluviatilis — the first being Says & the last Mr. Lea himself states was Lister's "Mya fluviatilis"— Now if the removal into its proper Genus be a sufficient claim certain- ly Mr. Say could rightly claim this species since he honestly described it as A. cataracta" whereas Mr. Lea never described it at all still claims it by stealing Listers name and clapping his own at the end as Author— just as he did with Solanders "complanatus" — If I had time & Patience I could point out other as glaring errors but I have said enough — excuse my plainness - - my Quaker blood and training never taught me to mince matters where injustice was concerned. Please let me hear from you on the subject. Very truly yrs John G. Anthony OCCASIONAL PAPERS ON MOLLUSKS 89 In 1838 Mrs. Thomas Say presented Anthony with two new species of shells which she had collected at the Falls of Kan- awha in Virginia. These were given with the distinct under- standing that one of them should be named after her particu- lar friend, Dr. J. P. Kirtland, who was also a friend of Anthony. This he says "accounts for the departure from a long cherished rule not to name species after individuals thus to propitiate the inordinate vanity of some ignorant collector." Consequent- ly Anculosa kirtlandiana and Amnicola say ana are unique in being Anthony's only patronymics. All other species published by him have descriptive names. According to Anthony's notes Mrs. Say illustrated a number of shells for him; among them were Anculosa kirtlandiana and A. carinata, the two she had collected. By 1863 Anthony had published five papers on fossils and ten on mollusks, several of which were read before the Boston Society of Natural History, of which Agassiz was a member. By this time Anthony's correspondence and exchanges had grown to considerable proportions, and he hoped for a position in a museum or other institution in which he could earn a liv- ing while working on shells. At that time the Museum of Com- parative Zoology at Harvard was four years old and growing rapidly, and though Agassiz had considerable student help he was looking for an assistant in Mollusks. Their letters crossed in the mail — the one Anthony wrote to Agassiz asking for a position and that of Agassiz offering the position to Anthony. Louis Agassiz in his annual report of the Museum of Com- parative Zoology for 1863 writes "It has been my good fortune to secure the co-operation of Mr. J. G. Anthony, who has been for nearly forty years one of the leading conchologists of Amer- ica, and his zeal and activity, as well as his exquisite neatness in putting up specimens will soon change the whole aspect of that department of the museum." Thus, in August 1863 An- thony, at the age of 60, arrived in Cambridge to become a part of one of the most active and important institutions of its kind in the new world. During the fourteen years in which Anthony was Assistant at the Museum of Comparative Zoology he did much to build up the Department of Mollusks. It is to him that we must give credit for the presence in the collection of many of the type 90 OCCASIONAL PAPERS ON MOLLUSKS specimens of the early workers in conchology. At this form- ative period in the development of malacology, Anthony's in- terest in the collection was paramount and, because of his willingness to carry on extensive exchanges with Hugh Cum- ing, Lovell Reeve, Temple Prime, James C. Cox, H. Dohrn and others, material poured into the laboratory almost faster than Anthony was able to absorb it. The Cuming material, especial- ly that from the Philippines, was an invaluable addition to the collection as it was composed almost entirely of types. Anthony also sold his collection to the museum and with it came numer- ous types which he had previously obtained as well as his large collection of North American fresh-water shells. Following the accepted procedure of the day Anthony aimed to have every species of mollusk on exhibit and consequently he spent a large part of his time carefully gluing specimens to slate, glass and wooden plaques. Carefully written, detailed records were kept of the exact number of specimens mounted each month. The following excerpt was taken from his annual report for 1869. " In the past 12 months we have added 9250 tablets to the 17 [thousand] then on hand so that we have 26250 tablets mounted with 67749 specimens. Of this number 22403 tablets have been mounted by the writer during the six years he has been connected with the museum, and the remaining 3847 tablets have been added by the three female assistants, who under the policy recently adopted have been mostly em- ployed in preparing tablets, but who have also occasionally been allowed to mount the specimens under proper supervi- sion." Again in. 1870 he wrote "Besides the important addition of 2417 mounted tablets to our previous number, I have, in the process of re-arrangement, found it necessary also to remount a very large number of the species. This has been owing to the unsatisfactory nature of the cement first used for the pur- pose, the very dry atmosphere of our exhibition rooms oper- ating unfavorably upon all the cements known, at the time when we commenced this mode of exhibiting shells. Much time and labor has been bestowed upon this problem of the best cement for the purpose, and I am happy to be able to say that I have so far succeeded in removing all difficulties that we may reasonably hope to be spared hereafter the time and labor of remounting, our present cement seeming to be all that we could desire or expect." OCCASIONAL PAPERS ON MOLLUSKS 91 With the change in curatorial procedure those who have followed Anthony have had to spend a great deal of time re- moving these same specimens from their plaques. The glue was certainly all that Anthony had hoped it would be I In working up the Anthony types in our collection we came across a box of Amnicola cincinnatiensis Anthony containing over 2000 specimens and the following note was left by W.F.Clapp "These were all glued on tablets, 12 per tablet." Obviously these could not all have been for exhibit but had probably been prepared for exchange. Anthony had an unusually beautiful handwriting, his labels looked like steel engravings and his notes were so neatly and perfectly written that one would think that they had been printed. Agassiz, appreciating this art, often asked Anthony to copy addresses and poems which were to be presented to friends and benefactors of the museum. In a letter to his wife Anthony tells of copying the address written by Oliver Wen- dell Holmes on the occasion of the dinner given to Agassiz be- fore leaving on the Thayer Expedition. Holmes also wrote a poem on this expedition which was presented to the Emperor of Brasil and again it was copied by Anthony. In 1865 Anthony accompanied Louis Agassiz and others of his staff on the Thayer Expedition to Brasil. Anthony's letters to his wife written during the early part of the trip continually refer to his improved health and his increased ability to eat, for he had been suffering for some time with a chronic stomach ailment. However, despite his improved condition Anthony did but little collecting for the expedition as he contracted yellow fever shortly after arriving in Rio de Janeiro and con- sequently returned to Cambridge. While other members of the party continued to collect mollusks to some extent there was no published report made on the material collected on this ex- pedition. John Henry Blake became a member of the Museum staff in 1867 and for the next ten years was a close friend of Anthony. The following notes have been taken from Blake's letter to William J. Clench in which he gives an informal picture of the museum's first curator of mollusks as he remembered him. "From the time I first knew him [Anthony] until his death 92 OCCASIONAL PAPERS ON MOLLUSKS we were the best of friends, although there was friction be- tween him and others in the Museum. " I have even thought I was assigned a table next to him, by Prof. Agassiz, partly because of his disposition to be easily disturbed. "The first section of the museum only was then built, and the accommodations for workers were limited. In this room, at one time, there were nine or ten persons, and in some places, the trays of specimens were piled much higher than one could reach. There were no cases for trays in this room. ''He did not go home to lunch but brought a brown, pint bottle containing milk, egg and a little brandy which was his lunch, and he left the museum for the day at 3 o'clock P.M. Before he left, however, he brushed all his dirt out by my table and left it there. This act was as regular as the day but I never remonstrated. When he was sick at his home, corner of Mag- azine and Green Streets, Cambridgeport, he always wrote to me and I visited him many times on errands in connection with his Museum work. If he wanted acid, or chemicals to make the glue used extensively in his work I would buy it at John Hubbard's in Harvard Square, on my way to my boarding place on Mt. Auburn Street. 'T do not remember his writing a scientific paper, not count- ing his regular annual reports, while at the Museum. His time seemed to be taken chiefly in preparing specimens for exhibi- tion or exchanges. He devoted much time in mounting speci- mens on wood, card, slate and painted glass. He was always making improvements in his glue as I heard him tell Professor Agassiz a number of times. "He was a very steady worker and hardly left his chair from the time he came 'til he went. He did not attend Prof. Agassiz's lecture in the next room with the rest of us. These lectures by Professor Agassiz were very popular. Although they were regular College lectures I have seen the room crowded, floor and gallery, extra chairs taken in and yet Mr. Anthony re- mained at his work. "He often made puns or played upon words. He liked to tell a joke but did not like to have a joke played on him. As an example: One 1st of April Dr. Wilder and I attempted a joke. We got an old dry "mermaid" from the attic, put it in a box OCCASIONAL PAPERS ON MOLLUSKS 93 and got Mr. Roetter to put on it in German script Mr. Anthony's address with "you are an April Fool" in the corner. Mr. Anthony came in saw the box and with some gusto said he had received a box of shells. He was a little puzzled over the address so took off the cover, saw the contents and took the cover to Mr. Roetter to read. Mr. Roetter read it ending with the "you are an April Fool." Mr. Anthony was so mad he took the box out of the room, and I have not seen the "mermaid" since, he never spoke to Dr. Wilder after. I told Mr. Anthony I was as guilty as Dr. Wilder but he said he could excuse me as I was young, but Dr. Wilder was too old to play such a joke." As is evidenced from J. Henry Blake's letter, Anthony's ill health not only caused his absence from the Museum for long periods of time, but was no doubt partially responsible for his lack of research after 1866. On October 16, 1877 Anthony, then 73 years old, died at his home in Cambridgeport of cancer of the stomach. He was buried at the Swan Point Cemetery in Providence, Rhode Island. The year of his death, Alexander Agassiz, then Director of the Museum of Comparative Zoology, paid Anthony the follow- ing tribute in his Annual Report. ". . . . his time and energies were given to the department of Conchology with such assid- uous and entire devotion as is rarely equaled. He had held cor- respondence and conducted exchanges with almost all active conchologists and shell collectors of his time, who never failed to appreciate the remarkable skill in exchanging, the complete knowledge of the relative value of specimens, and the wide acquaintance with the traditions of conchology, which were the fruits of his long experience." Though a great many of Anthony's species have fallen into synonymy he made many important contributions to Conchol- ogy and to the Museum of Comparative Zoology in particular. The following note by Calvin Goodrich, who today is the man most capable of judging Anthony's work on the Pleuroceri- dae. "I would say that Anthony was of very real importance in his day in that he made collections when collectors were few and far apart, that he did this when contacts with other nat- 94 OCCASIONAL PAPERS ON MOLLUSKS uralists were almost non-existent — a very lonesome sort of career that he made descriptions according to his lights, and these were no worse, and sometimes better, than those of his contemporaries. In the end, the collection remained intact, and available — a thing it would be difficult for us to put too high a price upon." Acknowledgments The author is indebted to Miss Fanny Garrison, grand- daughter of J.G.Anthony, for much valuable information and especially for the gift to the Museum of Comparative Zoology of many of Anthony's letters and unpublished notes. Thanks are extended to Professor W. B. Hendrickson of MacMurray College for the loan of material which he had gathered on the Western Academy of Natural Sciences. For copies of An- thony's letters and other information on his life we are indebted to Dr. Harald Rehder, the United States National Museum; Dr. Henry Vander Schalie, the Museum of Zoology at the Uni- versity of Michigan; Miss Lillian C. Wuest, reference Librarian of the Historical and Philosophical Society of Ohio; Miss Ethel L. Hutchins, Reference Department of the Public Library of Cincinnati, Ohio; and Mr. George F. Johnson, Deputy City Registrar, Providence, Rhode Island. Mr. Calvin Goodrich gave many valuable suggestions, especially on the evaluation of Anthony's work.

This manuscript name of Mighels was first introduced by Anthony as a synonym of Schizostotna Lea 1843 {non Bronn 1834; non Schlaeter 1838) in a letter which was published as above. As Apella 'Mighels' Anthony equals Schizostoma Lea, it is the next available name for this genus as Schizostoma Lea is a homonym. This will replace Gyrotoma Shuttleworth 1845, as Apella has two years priority. arachnoidea, Melania: 1854, ALNHNY 6, p. 95, pi. 2, fig. 14 (small stream emptying into the Tennessee River near Loudon, Tennessee) [Holotvpe MCZ 50236]. assimilis, Melania: 1860, PANSP, p. 60 (Tennessee) [Cotypes MCZ 161827]. athleta, Melania: 1854, ALNHNY 6, p. 83, pi. 2, fig. 1 (Tennessee [Bacon Creek near Mumfordville, Kentucky] ) [Holotype MCZ 161751]. attenuata 'Anthony' Reeve, Melania: Conch.

Pilsbry (The Manual of Conchology. 1901, 14, p. 173) states "is a lost species which American students have not been able to trace." Among Anthony's unpublished notes is the following "The only Bulimus herein de- scribed is Bulimus vermetus and it is somewhat doubtful if this is clearly en- titled to be included in that genus. Its round, continuous aperture, it is true, would indicate that as its appropriate position but as some of the Limneae occupy localities nearly or quite as dry as this was found in. and. as but for its connected aperture, it much resembles L. humilis, it is not improbable that closer observation may prove it to belong to the later genus. Its unusual thinness and sharp linear form are more indicative of Limnca than they are of Bulimus. Only three specimens have as yet been noticed, when numerous individuals shall have been examined some definite conclusions will no doubt be arrived at with regard to its generic character." Anthony never found any more specimens, or if he did his vermetus proved 108 OCCASIONAL PAPERS ON MOLLUSKS to be nothing more than malformed L. humilis and he no longer kept the specimens separated.

Johnson Since Thomas Say first described A. implicata in 1829, there has been much confusion regarding its identity. This was brought about chiefly by a misunderstanding as to what spe- cific characters separate this species from the other members of the Genus Anodonta, and by an absence of good ecologic data. The following description and remarks are based mainly on a rather extensive collection of this species in the Museum of Comparative Zoology. I wish to express my thanks to Dr. H. A. Pilsbry of the Academy of Natural Sciences of Philadelphia and to Dr. H. A. Rehder of the United States National Mu- seum for the privilege of studying the specimens of this spe- cies in their collections.

Description. Shell often large, reaching from 130 to 165 mm., rather solid and heavy for an Anodonta. Outline elongate- elliptical to elongate-ovate. Valves quite inflated, somewhat sub-cylindrical. Anterior end regularly rounded ; posterior end more acutely rounded, older specimens often becoming sub- truncated. Ventral margin slightly rounded, becoming straight or somewhat arcuate in old specimens. Posterior slope slightly compressed, sometimes elevated and slightly alate at the up- per posterior angle. Posterior ridge usually well developed and biangulated. Hinge ligament prominent. Beaks well forward of the center, slightly swollen and moderately convex, their sculpture consisting of four or five wavy recurved ridges. Surface of the shell rather smooth, save for growth lines and occasional plaiting of the periostracum. The latter is usually heavy, yellowish brown or greenish brown, sometimes becom- ing reddish brown or almost black in old specimens. Young specimens are sometimes greenish and may be obscurely rayed. Hinge edentulous, forming a moderately curved line. Beak cavities rather shallow. Muscle scars distinct, well im- pressed in old specimens. Shell distinctly thickened along the anterior margin below the pallial line. Nacre dull opalescent, generally pale copper, pinkish, or more rarely white or bluish white, usually with a bluish cast toward the margins. There is a difference in the shape of the shell in the two sexes, but it is sometimes difficult to recognize with certainty. The fe- male is usually more swollen than the male in the middle por- tion of the disk, which tends to make the lower margin more curved and the shell somewhat shorter and higher than that of the male.

This locality is still relatively close to Say's and is about in the center of the range of the species. Dr. Harald Rehder of the United States National Museum has been unable to locate the holotype of Lea's A nodonta newton- ensis, therefore we select Lea's paratype USNM no. 86561, Schuylkill [River, Fair Mount] near Philadelphia, [Pennsylva- nia], as lectotype. The location of Linsley's type of A. housa- tonica is uncertain, but it is probably in the A. A. Gould col- lection, now in the New York State Museum. Breeding Season. According to Ortmann (1911, p. 303) all Anodonta are bradytictic, or winter breeders, the marsupia filling sometime in summer between July and September. The eggs develop rapidly, and the glochidia are generally fully de- veloped in September or October. However, they are not then discharged, but are usually carried through the winter in the marsupium and are not set free until warmer weather begins, that is in April, May or June of the following year. I have col- lected gravid females on May 8, 1943, and on June 9, 1946. Glochidia. The glochidia are typical of the genus Anodonta, being rather large, subtriangular, with a spine at the tip of each valve. According to Coker (1921, p. 144) all hooked glo- chidia generally, though not invariably, attach to the exterior and exposed parts of the fish, the fins and scales. The glochidia of A. implicata have been found, by the author, on the gills of the host as well as the fins. Host. The Alewife, Pomolobus pseudoharengus (Wilson) \ which serves as host for the glochidia of A. implicata, ranges from Nova Scotia to North Carolina. ''The first alewives ap- pear early in April in the few streams tributary to Massachu- setts Bay that they still frequent, but are seldom seen in Maine rivers or in the St. John until late April or early May. There- after successive runs follow (the last part of May seeming the Identified by W. C. Schroeder, Associate Curator of Fishes, Museum of Comparative Zoology. OCCASIONAL PAPERS ON MOLLUSKS 113 heaviest) until well into June." - Closely allied to P. pseiidoha- rengiis is another alewife Pomolobus aestivalis (Mitchell), whose range overlaps the former's, but extends farther south. Although this species has not been examined for glochidia, it might possibly serve as a host to A. implicata. Distribution. Simpson (1914, p. 391) gives the range of this species as "St. Lawrence-drainage north to Lake Winnipeg; south in streams flowing into the Atlantic to Virginia." It is certain that Simpson did not understand this species. So far as known, it ranges from New Brunswick and Nova Scotia south to Virginia, being restricted to ponds and streams near the coast that are frequented by the alewife. Ecology. Although often found in relative abundance in ponds, this species seems to prefer a stream environment, and it is from a relatively swift stream that the largest examples have been taken. It is generally found on a sand or gravel bottom, rarely in mud. Records. Nova Scotia: Grand Lake, Halifax Co. (MCZ). New Brunswick: Grand Lake, Queens Co. (MCZ).

Distributional pattern of Anodonta implicata Say in the Northern Atlantic States. Since the plate was prepared an additional record of this spe- cies was received from the Potomac River, District of Columbia, which extends the range about one hundred miles farther south. (Map drawn by R.D.Turner) OCCASIONAL PAPERS ON MOLLUSKS 115 Remarks. Since the original description of this species was based on an immature specimen (measuring 3.5 by 1.5 inches) and was not figured, it has often been confused with other species of Anodonta. Nevertheless, traditionally this is the species generally accepted as representing Say's description and to avoid confusion in the future we have selected a neo- holotype (see under Types) pi. 16, fig. 1-2. The most reliable and constant feature in identifying adults of this species is the pronounced thickening of the anterior margin below the pallial line. This is not always pronounced in young specimens but may still be detected. In addition, the dark and usually yellowish or brownish, rayless periostracum and the pale copper or salmon color of the nacre will ordinarily serve to distinguish this species from any other Anodonta in eastern North America. This species has never been found in any pond or stream which is not frequented by the alewife. During the last cen- tury A. implicata was very abundant in Fresh Pond, Cam- bridge, Massachusetts; but in recent times, since the outlet has been closed, and the alewife no longer frequents the pond, A. implicata has become extinct, and today A. cataracta is the only Anodonta to be found at this locality. At one time A. im- plicata must have been found in many more localities than it is today, but the alewife has become more and more restricted locally in its distribution because of damming and stream pol- lution, with the result that A. implicata also has become ex- tinct over portions of its range. As has been mentioned, Simpson (1914, p. 391) seems not to have understood this species. Ortmann (1919, p. 161) on the other hand, even with but little material, has described A. im- plicata well, and has listed several records from the extreme coastal region of Pennsylvania, thus indicating he had consid- erable knowledge of its distribution. F. C. Baker (1942, p. 75) has erroneously reported this spe- cies from several ponds in Carroll Co., New Hampshire, claim- ing that A. implicata and A. cataracta are very variable and often difficult to separate. He bases his differences on the beak sculpture and coloration both of which are at best variable characters. He also claims that the periostracum of A. impli- cata is often a vivid green near the posterior end. Baker's speci- 116 OCCASIONAL PAPERS ON MOLLUSKS mens were certainly only off-colored A. cataracta. In addition he has reported A. implicata from Oneida Lake, New York (1916, p. 253, fig. 41, no. 2). Here again, this is another species of Anodonta. The figured specimen is not A. implicata and the locality, as well, is outside of the known range of the alewife. Bibliography Baker, F.

Clench ^..^b^a hj- Various species and color forms of Ligtnis are found in His- paniola, Cuba, the Isle of Pines and southern Florida. They are arboreal in habit, feeding mainly on bark-growing lichens and descending from the trees only to lay their eggs in the moist ground. After hatching, the young snails ascend the trees and generally feed first on the leaf-growing lichens, but soon start feeding on the twigs and small branches and then later the lichen-covered bark of the main branches and trunk. It is possible that this genus may survive on many of the remote hammocks in the Everglades, at least for a time. I doubt very much, however, that they can survive indefinitely, in spite of collecting restrictions, even within a park area. Drainage and the consequent fires during the dry period will reduce their numbers until eventually they will disappear. The situation in Cuba and Hispaniola has a much brighter outlook, though even on these two islands the same factors are at work and many colonies which were common a few years ago are now extinct. The main difference is that here Liguus is far more extensively distributed even though local- ized as to colonies. They are not at all coextensive with the forested areas. ' ' > V 117 118 OCCASIONAL PAPERS ON MOLLUSKS Liguus appear to be colonial in habit. This is certainly true in Hispaniola and Cuba where colonies exist which have very definite limits in the territory they occupy. In Florida the sit- uation is different only because there are very specific limits to the type of habitat they can occupy; i.e., the hammocks or islands of the Everglades and the hammock land of deciduous trees which exists along the Miami ridge and on the lower keys. Liguus in this regard is similar to Cerion in Cuba. A colony of either may occupy only a small portion of a larger region of uniform habitat. The flora, general geology of the terrain and other factors appear to be exactly the same, yet the snails are found in but a small portion of what appears to be an entirely uniform ecological situation. Liguus, in common with many other land shells, possesses two color phases, exhibited mainly in the embryonic whorls. In the fasciatus complex, this color occurs on the parietal wall as well. Thus shells with a similar color pattern will occur with white embryonic whorls and a white parietal area, or with a pink spire tip and parietal area. Unfortunately, classi- fication as to species was arbitrarily made on the basis of white or pink tipped shells. A yellow banded shell with a pink tip was called Liguus fasciatus roseatus and a similar yellow banded shell with a white tip was called Liguus crenatus cin- gulatus. Though still separated as ''forms" the best grouping is to consider all under the older species name of fasciatus. The name crenatus is limited to the white shells in the central Cuban region that are all apparent albinistic forms of Liguus fasciatus s.s. This classification is, of course, still highly arti- ficial but it is far better than the older procedure where the progeny of a single individual were automatically classified under two species.

To avoid any later confusion in the use of the name Ilotia Pfeiffer and Clessin 1881, it is here designated that Bulla virginea Linne is the genotype, thus making it an absolute synonym of Ligu- us Montfort 1810 which has the same genotype. innominatus Pilsbry, L.s.: 1930, N 44, p. 32; figured in the M of C (2) 12, pi. 59, fig. 97, 1899 (No Name Key, Florida) [Holotype ANSP]. jaumei Clench and Aguayo, L.b.: 1932, N 45, p. 99, pi. 6, fig. 10 (Mangas, on road between Mangas and Candelaria, Pinar del Rio, Cuba) [Holotvpe MCZ 91720]. josefae Guitart, L.f.: 1945, RSM 3, p. 29, pi. 4, fig. 3-4 (Cortinas de Coren- gue, Sierra de Cantu, Sancti Spiritus, Cuba) [Paratypes MCZ 153815; Museo Poey]. leonorae Pequeno, L.f.: 1938, Memorias Sociedad Cubana Historia Natural 12, p. 347, pi. 26, fig. 1-4 (Monte del Limon, near Cueva de la Pintura, La Grifa, Guane, Pinar del Rio, Cuba). lignumvitae Pilsbry, L.f.: 1912, JANSP (2) 15, p. 461, pi. 37, fig. 4-4d (Lig- num Vitae Key, Florida) [Holotype ANSP; Paratypes MCZ 48153].

Liguellus, new subgenus Shells are characterized by being ovate in shape, somewhat smaller than other Liguus in size and having moderately convex whorls. The interior of the aperture is generally pink. The color pattern is in spiral arrangement with no axial flames. Subgenotype, Achatina vittata Swainson This subgenus is closely related to Liguus s.s. It possesses a spiral color pat- tern and the interior of the aperture is pink. It differs from Liguus s.s. by hav- ing more rounded whorls, being ovate in outline and being smaller in size. It does not appear to be closely related to either L. fasciatus or to L. blainianus in the subgenus Oxystrombus. The number of colors in the spiral pattern is far more limited in Liguellus, than in Liguus s.s. There is a complete absence of green, red, and purple; colors which are generally present in L. virgineus, while L. vittatus possesses only black, brown and yellow. Only a single species ( vittatus) of Liguellus is known to exist and that is rather remarkably uniform in shape and color pattern throughout its rather 124 OCCASIONAL PAPERS ON MOLLUSKS limited range in the Province of Oriente, Cuba. It appears to be indifferently sinistral and dextral, that is, most colonies contain specimens of both forms. This is not to be confused with the rare examples of sinistral specimens which may occur sporadically in any color form of the other species of Liguus. A few such cases are on record.

This species very probably came only from Key West, Florida as nothing approximating this species has since been found in Cuba. As Liguus was known to occur in Cuba long before any Florida forms were known, unlocalized ma- terial was assumed to be Cuban. Very probably L. picta was early extermi- nated. The island of Key West was the only island in the early days that was readily accessible from the sea among the lower Florida Keys. Wood for fuel and other uses was at hand but limited so that the hammock land was soon cleared with a consequent extermination of any Liguus population. Also the nearest color form to picta is L. solidus solidulus which still exists or did exist up to a very short time ago on Stock Island, the next island east of Key West. pilsbryi Clench, L.b.: 1935, N 48, p. 123, pi. 7, fig. 1 (Campo de Tiro. 7 km.

He lists only two species, namely, Achatinav/i virgineam Linne and Cer- ithium telescopium Linne. Achat inam virgineam Linne is here designated to be the genotype, thus making it an absolute synonym of Ligims Montfort which has the same type designation. In the M of C (2) 12, 1899, p. 161, Pilsbry clearly indicated Pseudotrochus as a synonym of Liguus s.s. and credited the genus to Morch 1852. In a later volume (M of C (2) 16, 1904, p. 219) he overlooked this earlier usage and dated it from H. and A, Adams 1855 for an African genus. This later use is invalid under the rules of the International Commission of Zoological Nomen- clature inasmuch as Herrmannsen's Index and the Catalogue of the Comes de Yoldi Collection by Morch are accepted publications, and as such, names pro- posed in them are valid. Pseudotrochus of authors (non Herrmannsen 1847; Morch 1852; Heilprin 1887; Kittl 1899) will have to take the name Lignus Gray 1834, Proceedings of the Zoological Society London 2, p. 66, with the genotype, Lignus tenuis Gray here selected. Gray very probably intended to write Liguus to include this species, but he did not correct it in any later volumes of the Proceedings and it is listed in the index as Lignus. Neave (Nomenclator Zoologicus 2, 1939, p. 942) lists it as a validly introduced genus. puellaris 'Roeding' Pfeiffer and Clessin, Ilotia: 1881, Nomenclator Heliceorum Viventium, p. 260 (Haiti) [is virgineus Linne, Pfeiffer and Clessin above]. puellaris Roeding, Plotia: 1798, Museum Boltenianum, p. 96 (no locality given) [is Bulla virginea Linne, Roeding above]. roseatus Pilsbry, L.f.: 1912, JANSP (2) 15, p. 448, pi. 38, fig. 11-llb (Good- land Point, Marco Island, Lee Co., Florida) [Holotype ANSP]. roseus Pilsbry, L.f.: 1912, JANSP (2) 15, p. 461 [error for roseatus Pilsbry]. russelli Clench, L.fl.: 1935, N 48, p. 125, pi. 7, fig. 2 (Mogote Mina Con- stancia, Vinales, Cuba) [Holotype MCZ 82980]. sanchezi Ledon, L.f.: 1944, RSM 2, p. 11, pi. 3, fig. 3 (Loma de Ponce, pa- sado el Rio Caburni, Trinidad, Province of Las Villas,* Cuba) [Paratype, Museo Poey]. sanctispiritensis Guitart, L.f.: 1945, RSM 3, p. 31, pi. 4, fig. 7-10 (Loma Caja de Agua, Finca Las Delicias, Tuinucu, Sancti Spiritus, Cuba) [Para- types MCZ 153814; Museo Poey]. * This is the Province of Santa Clara.

Occasional Papers On Mollusks Published by The Department of Mollusks Museum of Comparative Zoolojjy, Harvard University Cambridge, Massachusetts VOLUME 1 SEPTEMBER 20, 1947 NX'MBER 11 Edward Sylvester Morse With a Bibliography and a Catalogue of his Species By Merrill E. Champion It is often remarked that scientific men nowadays tend more and more to become specialists, usually in quite narrow fields. Graduate collegiate degrees are the rule rather than the ex- ception. Edward Morse, however, was not of this pattern. He had no college degree and had to educate himself, yet he be- came outstanding in the fields of zoology, ceramics and eth- nology; he even got some reputation in astronomy. Four uni- versities gave him honorary degrees. The brief outline of his career which follows is intended to focus attention on some of the accomplishments of this remarkable man. Edward Sylvester Morse was born in Portland, Maine, June 18, 1838. His father, Johnathan, a partner in a firm dealing in furs, was a deacon in the church and a rather narrow-minded individual who failed to understand this son whose interest centered in the collection and study of mollusks. His mother, more broad-minded and more perceptive than the father, re- tained a profound influence over Edward as long as she lived. The boy had also a friend, of his own age, John M. Gould, of kindred tastes, who through the many years ahead was a source of friendship, encouragement and even of financial aid. Many of Morse's most self-revealing letters were to this friend. At the age of twenty Edward began a diary which he kept up all his life. This diary serves as a rich source of informa- tion about the writer himself, his way of reacting to life, and the chief events of his career. 129 130 OCCASIONAL PAPERS ON MOLLUSKS Young Morse did not take very kindly to the sort of school- ing then provided in his native Maine. He got expelled from the Academy at Bridgton and went to work as a draftsman. Returning to another school— this time at Bethel— he received encouragement to continue his interest in natural science, an interest which dated back to his childhood when he had begun to collect shells at the age of twelve. It was while at school in Bethel that he found a mollusk new to science which he named Helix asteriscus and reported to the Boston Society of Natural History. This was in 1856 when he was eighteen years old. Two years later he reported another new mollusk to the Bos- ton Society, which he named, Helix milium. In spite of this early introduction to science, Morse evidently failed to get from his early schooling the elementary knowledge of the humanities which high schools are supposed to impart to their students. He had to learn by experience and contact with the world. He did learn and later in life held his own with the best on three continents. His progress can be gauged by the entries in his diary and by his letters. Edward Morse's scientific interest in malacology did not go unnoticed. Word got round about his cabinet of shells. Judge Cooper came to look it over. William Stimpson, then at the Smithsonian Institution, also made a visit. Results of great import to the future career of Morse followed. First came an invitation from Stimpson to accompany him on a scientific trip to Mount Desert. This had to be refused because of the cer- tain disapproval of the elder Morse. Then there came a letter from W. G. Binney, at that time an outstanding figure in con- chology, inviting the young amateur to correspond. Not long after these events, and following words with his father, "Ned" Morse went to Boston to take a job as a drafts- man. This gave him the opportunity of attending the meetings of the Boston Society of Natural History where he saw Louis Agassiz. However, after a short time, out of money, he had to return to Maine. Up to this point nothing that had happened seemed to give promise of a permanent career in science. Nevertheless events were in the making which were to change the complexion of things for Edward Morse. A visit from another well-known conchologist was the starting point. In May, 1859, P. P. Car- OCCASIONAL PAPERS ON MOLLUSKS 131 1838-1925 Plate 18. From an original photograph 132 OCCASIONAL PAPERS ON MOLLUSKS penter, over from England and working at the Smithsonian Institution, called on Morse at Portland to see his shell collec- tion. Not long afterwards a letter came from Carpenter stat- ing that he had told Agassiz of Morse's interest in shells and of his drafting ability. Carpenter went on to say that Agassiz had expressed a wish to see the young conchologist. Morse started for Boston that night. Next day he saw Agassiz, saw the Museum of Comparative Zoology with him and was told to return in the fall as a student-assistant at the Museum. This he did on November 1, 1859. Morse began his Cambridge experiences when he was twenty-one years old. His position was that of student-assistant at the new Agassiz Museum and his salary was $300 and found. This was to prove an interesting and formative period in Morse's life, both because of the educational opportunities in- volved and because of personal contacts with Agassiz and with a group of younger men all of whom were to become famous in later life: Verrill, Hyatt, Packard, Shaler, to mention a few. Nevertheless after a time dissatisfaction grew on him. He was not getting all the salary promised him. Agassiz had not paid him anything for the collection of shells he had made in Maine and turned over to the Museum. Then there was the unsettled state of his mind caused by the beginning of the Civil War. Morse wanted to enlist but was being urged not to do so by his mother and his fiancee. Finally at the end of 1861, after two years at Cambridge, Morse resolved to quit the Museum and go back to Maine in the hope of making a living as a draftsman and lecturer. He made a start at this, doing work for Binney, Bland, Prime and others. Nonetheless the urge to have a share in the Civil War was still with him and led him to enlist on August 25, 1862. Rejected on the physical examination, he went to work for the Portland Cement Company at nine dollars a week. Within a year he married Elizabeth Owen to whom he had long been engaged. In 1864, one of the disappointments which had been at the bottom of Morse's leaving Cambridge was removed: Agassiz paid him $250 for the shells given the Museum in 1860. In March of this same year appeared Morse's first long article "Observations on the Terrestrial Pulmonifera of Maine, In- OCCASIONAL PAPERS ON MOLLUSKS 133 eluding a Catalogue of all the Species of Terrestrial and Flu- viatile Mollusca known to Inhabit the State." Morse did the illustrations himself. This scientific effort brought him appre- ciation and praise from such men as William Stimpson of the Smithsonian Institution and Isaac Lea, but very little financial return. During this period, Morse did a good deal of lecturing at which he was quite successful. He was a ready speaker and was able to enliven his talks by blackboard illustrations, using both hands at once. Back in Portland, Morse continued his interest in malacol- ogy. He was made Curator of the Portland Society of Natural History. However, the fire that ravaged Portland in 1866 de- stroyed the rooms occupied by the Natural History Society. Morse and others saved some of the contents but the job of Curator lapsed for lack of money. In spite of this setback, the year 1866 saw Edward Morse started on a permanent career. He went to Salem, Massachu- setts to make some drawings for a work by Hyatt and Salem became his home for the rest of his life. In November of this year 1866 Morse and three of his friends, A. S. Packard Jr., Alpheus Hyatt and Frederick W. Putnam, joined in starting a scientific magazine which was given the name of the American Naturalist. This publication lasted un- til 1878. Those interested in Morse's early contributions to malacology have occasion to refer often to the issues of the American Naturalist. In fact the leading article in the first number of the new magazine, which is dated March, 1867, was by Morse on the shells of New England. A large gift of money by the famous philanthropist George Peabody made possible the establishment of the Peabody Academy of Science in 1867 at Salem, Massachusetts. Edward Morse and some of his former companions at the Museum of Comparative Zoology became members of the staff, Frederick W. Putnam being named Director. Morse himself served as a curator from 1868 to 1871; as Director from 1880 to 1914; and as Director emeritus from 1914 until his death in 1925. In 1871 Morse separated himself — temporarily as it turned out — from the Peabody Academy in order to travel through- out the United States giving popular lectures on science. At 134 OCCASIONAL PAPERS ON MOLLUSKS the same time research was not neglected, and he lectured on zoology at Bowdoin, Maine State and Harvard. This period of the seventies was one of great activity and accomplishment and included academic recognition of his scientific attainments. In 1871 Bowdoin College gave him the degree of Doctor of Philosophy. In 1873 Agassiz invited him to lecture at his Sum- mer School of Science at Pennikese Island in Buzzards Bay, Massachusetts. In 1876 he became vice-president (and in 1886, president) of the American Association for the Advancement of Science. In 1877, Morse turned down an invitation to build up a department of science at Princeton. Dr. Walter B. Cannon in one of his essays discusses that form of indirection to which the term "serendipity" has been applied. He quotes Horace Walpole regarding the Three Princes of Serendip: ''As their highnesses travelled, they were always making discoveries by accident or sagacity, of things which they were not in quest of." In 1877 Edward Morse gave us a beautiful example of serendipity: he went to Japan to study brachiopods and returned a world authority on Japanese pottery. It came about in this way. For years Morse had been interested in the brachiopoda which, up to his time, had been classified with the mollusca. Painstaking investigation, however, starting with early fossil forms, convinced him that the brachiopods belong with the worms instead of the mollusks. This represents an outstand- ing piece of research and was recognized as such throughout the world, drav/ing a letter of praise from Charles Darwin. Incidentally, the labors that enabled him to write his essay 'The Brachiopoda, A Division of Annelida" (1870) resulted in his becoming a convinced Darwinian, thus separating him from the teachings of his old master, Agassiz. It was these same brachiopods that took Morse to Japan in 1877. Arrived there, he soon made such an impression on the Japanese authorities that they invited him to organize a de- partment of zoology at the newly-established Imperial Univer- sity of Tokyo and to set up a museum of natural history. Morse agreed to sign a two-year contract. Thus, without know- ing it, he took the first step on a road that was to lead to fame in an entirely new field of endeavor. The lucky accident which initiated this- as given in Dorothy OCCASIONAL PAPERS ON MOLLUSKS 135 Wayman's highly interesting and complete biography of Morse— happened as follows. Morse was having some trouble with indigestion in 1878. His Tokyo physician prescribed a five-mile daily walk and a hobby to make the tramp more in- teresting. The hobby was found by chance. During one of his rambles he came upon a saucer in the form of a shell. This led to a search for similar pieces of pottery. Then his Japanese friends undertook to improve his taste in this field of art and he took lessons from the greatest living Japanese expert. On the death of this expert, Morse became the expert himself. Ultimately he became consultant on Japanese pottery to the British Museum, the Royal Museum in Dresden, the Freer Art Gallery and the Boston Museum of Fine Arts. Thus it would seem that Morse as a serendipitist outdid the Princes of Serendip themselves. One other incident must be mentioned before taking leave of Morse's Japanese experiences. Soon after his arrival in Japan, while travelling by train to Tokyo, he caught sight of some shells on the railroad embankment near the village of Omori. These were fossil Area granosa which Morse considered to be part of a prehistoric kitchen midden. This glimpse into Japanese archaeology formed the basis of a paper on the Shell Mounds of Omori and played its part in determining Morse's relationship to Japan. It is interesting to note that this paper was the first publication of the University of Tokyo. Late in 1879 Morse returned with his family to Salem, re- fusing to renew his contract at the Imperial University. Ap- parently he had become a bit homesick and besides he wanted to finish his research on brachiopods and to do some lecturing and writing. The year following his departure from Japan he was offered and accepted the directorship of the Peabody Mu- seum in Salem — a position which he retained until his death. In spite of his many activities at home, Morse again felt an urge to visit Japan if only for a short time. This he did in 1883, returning by way of China, France and England. Pre-eminence in two widely-separated fields of research would seem to most men enough for one lifetime. But not so Edward Morse. While in Japan he became interested in the methods of arrow release of various races. From then on he spent many years in investigation of this field of ethnology. 136 OCCASIONAL PAPERS ON MOLLUSKS To him, the progress of civilization was reflected in five types of arrow release. The results of his studies were embodied in a bulletin of the Essex Institute entitled Ancient and Modern Methods of Arrow-Release (1885) and a later publication, Ad- ditional Notes on Arrow-Release (1922). While president of the American Association for the Ad- vancement of Science, Morse went to England in 1887 as a delegate to a meeting of the corresponding British association. After taking part in their proceedings, he travelled for a while on the Continent, visiting museums in Norway, Denmark, Sweden, Germany and Switzerland and conferring with men interested in his own diversified fields. Again in 1888 he visited Europe, this time as a delegate to the Congress of American- ists in Berlin. His last visit was in 1889 to perfect his collection of pottery. The remainder of Edward Morse's long life— some thirty -five years — was spent in his native country with Salem, Massachu- setts as his home base. His amazing diversity of interests con- tinually led him into new projects and new studies. Not con- tent with being a specialist in zoology, Japanese pottery and ethnology, he took up the study of astronomy with Percival Lowell at the Harvard Observatory. He even wrote a book called Mars and its Mysteries (1906) which won commendation from at least some of those qualified to judge. More significant, however, than his excursion into astrono- my was the publication of his Catalogue of Japanese Pottery (1891)— considered to be unique in its field— and of his journal entitled Japan Day by Day (1917). The journal— in two vol- umes—not only is a mine of information about Japan but throws much light on Morse himself. For the twenty-year period between 1881 and 1901, Morse published little in the field of zoology; then in 1901 appeared his Observations on Living Brachiopoda. Other papers followed dealing with various molluscan species. These continued un- til the end of his life. His last published paper (in 1925) dealt with Shell Mounds and Changes in the Shells Composing Them. On December 20, 1925, Edward S. Morse died at his home in Salem at the age of 87. Edward Morse's many-faceted nature and surprisingly var- ied attainments make it hard to get an adequate picture of OCCASIONAL PAPERS ON MOLLUSKS 137 him. Those in search of "success stories" can find ample ma- terial in his life. To quote Dorothy Wayman once more: "Edward Morse, without esthetic culture, without wealth, without a fully conceived purpose accomplished through his enthusiasm and appreciation the building of an artistic heritage for all humanity." His scientific curiosity led him into various fields of research. Zoology, however, was his lifelong interest. Morse did not describe many mollusks. His taxonomic re- searches produced one variety, eleven new species, one sub- genus, eight genera, and one subfamily. He certainly did not belong to the race of "splitters" who grasp at every chance to create new genera, species or subspecies even if it means merely adding to the synonymy. He quoted with approval Professor Keith's protest against the newer terminology: "Cursed be he that removeth his neighbor's landmarks: and all the people shall say, Amen" (Deuteronomy xxvii: 17). Old and established names, he thought, ought to be let alone and what Morse thought he phrased in vigorous language. As a zoologist, Morse was a careful observer, a good drafts- man and an indefatigable collector. He wrote well and was notably successful as a lecturer. In fact it may be said that in all of his varied activities he showed originality, boundless energy and enthusiasm, and catholicity of interests. He was an individual who did things, who questioned where others only accepted and who left behind him solid and permanent accomplishments; he was a distinguished scientist and a dy- namic personality. Acknowledgments The data on which this account of Morse's life is based come largely from Dorothy G. Wayman's highly interesting and complete biography. Her account has been accepted as the accurate one where disagreement has been encountered among those who have written about Morse. I am indebted to Mr. L. R. Jenkins, Director of the Peabody 138 OCCASIONAL PAPERS ON MOLLUSKS Museum in Salem, Massachusetts for interesting information about his predecessor, Edward Morse and for the opportunity of looking over material pertaining to Morse. Finally, I wish to acknowledge with thanks the assistance of William J. Clench, especially in the matter of decisions re- garding types. Bibliography Ball, William H., 1926, Obituary.

Occasional Papers On Mollusks Published by The Department of Mollusks Museum of Comparative Zoolojry, Harvard University Cambridge, Massachusetts VOLUME 1 SEPTEMBER 22, 1947 NUMBER 12 Lampsilis cariosa Say and Lampsilis ochracea Say By Richard I. Johnson Thomas Say described Lampsilis cariosa and Lampsilis och- racea in the first edition of Nicholson's Encyclopedia which appeared early in the year 1817. The present paper is an at- tempt to clarify the position of both species, for although they are distinct species, they have often been confused. The paper is based mainly on the extensive collections of both species in the Museum of Comparative Zoology and the United States National Museum. I wish to thank Dr. H. A. Rehder for the loan of the National Museum material and Dr. H. A. Pilsbry of the Academy of Natural Sciences of Philadelphia and Dr. J. R. Dymond of the Royal Ontario Museum of Zoology for allowing me to examine their collections. I am also indebted to Dr. Henry Vander Schalie of the Museum of Zoology of the University of Michigan for several records; to Dr. Gilbert Ranson of the Paris Museum for checking the identification of Lamarck's type of Unio liiteola; and to Mr. H. D. Athearn for specimens from Massachusetts.

Description. Shell usually medium in size, about 90 to 100 mm. in length. Outline subovate or obovate, sometimes ellip- tical; rather short and high, except male specimens which may be somewhat elongated. Valves usually not much inflated. Anterior end regularly rounded, posterior end more broadly rounded and sometimes developed to a distinct blunt point. Ventral margin slightly curved or almost straight. Posterior ridge rounded and poorly defined. Dorsal margin straight or somewhat convex, usually terminating in a blunt angle with the obliquely descending posterior margin. Hinge ligament prominent. Beaks moderately swollen but not much elevated above the hinge line and located at the anterior third of the shell. The sculpture consists of four or five wavy, recurved ridges (see Marshall 1890, p. 182, fig. 8). Periostracum smooth and shining, usually bright wax or straw-yellow, infrequently greenish-yellow, sometimes becoming a dirty brownish-yellow or reddish-brown in old specimens. Rays either entirely absent or, if present, almost always limited to the posterior slope; they are usually greenish or blackish and form a sharp contrast against the light background. Hinge well developed. Pseudo- cardinals usually two in each valve, those in the left valve be- ing compressed and serrated. The anterior tooth is somewhat triangular, the hinder one is low and rather long, located di- rectly under the beak. The anterior tooth in the right valve is vestigial, the hinder one stumpy, serrated and triangular. In- terdentum narrow. Two straight or gently curved laterals, which are somewhat elevated, truncated and raised toward their posterior ends are located in the left valve. One lateral tooth in the right valve. Beak cavities moderately deep, con- OCCASIONAL PAPERS ON MOLLUSKS 147 Plate 19. Fig. 1. Female Lampsilis cariosa Say. Neoholotype MCZ 178839 from the Schuylkill River, near Philadelphia.

Ortmann (1912, p. 353) claims that the anatomy of L. cariosa is similar to that of Lampsilis ovata ventricosa Barnes. Types. As Thomas Say's type of Unio cariosa does not exist, we here restrict the type locality to the Schuylkill River, near Philadelphia, Pennsylvania and select as neoholotype MCZ no. 178839, a female specimen whose measurements correspond approximately to those given by Say in the original description. A male shell from the same locality, MCZ no. 151644 is here selected as neoallotype. Neoparatypes, United States National Museum no. 84924. Lamarck's type of Unio luteola is in the National Museum in Paris. The description and type localities of this species w^ould place it in the synonymy of L. cariosa. Lea, however, claimed (1833, Transactions of American Philo- sophical Society, n.s. 5, p. 91) that the type specimen was iden- tical with L. siliqiioidea Barnes, and as Dr. Gilbert Ranson of the Paris Museum assures me that Lea's identification is cor- rect, it is doubtful if this specimen in question is truly La- marck's type. The type of Rafinesque's L. pallida is not known to exist. Breeding Season. According to Ortmann (1919, p. 315) this species is probably bradytictic. In Pennsylvania gravid females have been collected in the month of August. Host. The specific host of the glochidia of this species is un- known, but as L. cariosa is restricted in its distribution to ponds and streams which drain into the Atlantic, it might pos- sibly parasitize the alewife or some similar migratory fish. OCCASIONAL PAPERS ON MOLLUSKS 149 Distribution. Simpson (1914, p. 44) gives the range of this species as "the Atlantic drainage from Georgia to the lower St. Lawrence." Ortmann (1919, p 317) questioned the occur- rence of this species in the lower St. Lawrence drainage, but specimens from the Raquette River in New York (a stream which flows into the St. Lawrence River) MCZ no. 97981 seem to be this species and not the closely related La nips His ovata ventricosa Barnes. Lachford (1882, p. 50) has reported cariosa from Black Bay, Eardley, Province of Quebec, and La Rocque and Oughton (1937, p. 152) have reported it from the Lake On- tario drainage and the Ottawa River and its tributaries. Hav- ing seen at least a portion of this material at the Royal Ontario Museum of Zoology, I am inclined to regard it as misidentified. Gould (1870, p. 173) reports L. cariosa from ponds in Ply- mouth County, Massachusetts. The author and H. D. Athearn have collected in the area over a period of years and have found only L. ochracea. It is probable that Gould's record was based on a misidentification. The most southern record from the Ogeechee River, Georgia is based on a specimen in the Isaac Lea collection USNM no. 84915. It has a rather peculiar brownish-yellow periostracum, but it is undoubtedly this species. Ecology. In general L. cariosa prefers the swift waters of larger streams, being found on gravelly bottoms and on sand bars. Records.

As Ortmann (1919, p. 313) has pointed out, DeKay (1843, pi. 21, figs. 243, 244) has figured Lampsilis ovata ventri- cosa and not L. cariosa. Although related to the western L. ovata ventricosa, L. cariosa is quite distinct from it. In general, the latter is a smaller, less inflated shell, with hardly a trace of the posterior ridge which is usually present on the former. L. cariosa has a distinctive bright yellow, glossy periostracum; when rays are present they are almost always limited to the posterior slope. L. ovata ventricosa usually has a duller, oliva- ceous tint and is more inclined to be rayed over the entire surface. Generally L. cariosa has been confused with L. ochracea. Hartmann and Michener (1874, fig. 183, 184) have figured the two sexes of L. cariosa, the male as cariosa and the female as ochracea. Simpson (1895, Nautilus 8, p. 121), trying to clarify these species, recopied these figures and inadvertently perpet- uated the error. Gould (1870, fig. 475) has correctly figured a female specimen of L. cariosa, and though Ortmann (1919, p. 215) thought Gould's figure 476 was a male L. cariosa it is ac- tually a male L. ochracea, the figure being based on a specimen in our collection (MCZ no. 89723). Simpson (1914, p. 43) placed Unio oratus Conrad in the syn- onymy of L. cariosa, but its type locality, the Flint River, Georgia, would indicate that oratus is probably close to L. vi- rescens Lea and not to our Atlantic drainage species. Lampsilis ochracea Say Pectunculis Fluviatilibus [sic] Lister 1685, Synopsis Methodicae Conchylio- rum, pi. 157, fig. 12 ( Virginia ).i 1 Gmelin 1791. Systema Naturae, ed. 13, 1, pt. 6, p. 3359, named a shell from Europe Mytilus fluviatilis, referring to this figure of Lister as a shell which ap. proximated the European shell he was then describing. As he did not specifi- cally apply this name to Lister's figure, the name cannot be used for an Amer- ican shell. Further, though Conrad (1836, p. 37) considered Lister's figure to represent Say's L. ochracea, the figure is sufficiently ambiguous so that Isaac Lea was successful for over fifty years in claiming that M. fluviatilis Gmelin was Anodonta cataracta Say!

Description. Shell usually rather small, seldom exceeding 70 mm. in length. Rather strong, thin and often translucent. Outline ovate or subovate. Valves subinflated. Anterior end regularly rounded; posterior end usually produced to a blunt point. Ventral margin gently curved. Posterior ridge rounded and not very distinct. Dorsal margin slightly curved, terminat- ing in a blunt angle with the obliquely descending posterior margin. Hinge ligament prominent. Beaks moderately full, but not much elevated above the hinge line; they are located slightly more than one third from the anterior end. Their sculpture consists of several recurved ridges (see Marshall 1890, p. 180, fig. 7). Periostracum smooth or slightly wrinkled, especially in the post-dorsal region. It may be brownish-olive, greenish-yellow, brownish, yellow, reddish-yellow, or grayish- green, and is seldom shiny. Rays may be entirely absent or if present, are often found over the entire surface of the shell to a varying degree. They are usually dull green, rather fine, and often not very distinct. Hinge not well developed. Left valve with two, in rare instances three, long, narrow, somewhat compressed pseudocardinals which are located in front of the beak. Right valve with two triangular, narrow, compressed pseudocardinals, separated by a deep narrow pit. The more anterior tooth is the smaller and lower one. They are both al- most parallel to the hinge margin. Interdentum absent. The left valve has two thin gently curved, narrow laterals; the right valve one. Beak cavities shallow, containing dorsal mus- cle scars well impressed; posterior ones not very distinct. Pal- lial line not distinct.

As Thomas Say's type of Unio ochracea does not exist, we here restrict the type locality to the Schuylkill River, near Philadelphia, Pennsylvania and select as neoholotype, MCZ no. 178838, a male specimen measuring 44 mm. in length, 30 mm. in height, and 18 mm. in width. These measurements correspond closely to those given by Say in the original de- scription. Neoparatypes United States National Museum no. 84898. The type of Rafinesque's L. rosea is not known to exist. The figured holotype of Conrad's Unio rosaceus, is MCZ no. 178779. This specimen and nearly all the examples I have seen from the Savannah River have an attractive rose-tinted nacre. Breeding Season. Lea (1863, Journal Academy of Natural Sciences of Philadelphia n.s. 5, p. 455) reports this species gravid in the autumn. I have found gravid females on May 3, 1943 in Plymouth, Massachusetts. Host. The specific host of the glochidia is unknown, but like L. cariosa, L. ochracea seems to h^ restricted in its distribution to ponds and streams which drain into the Atlantic; but unlike L. cariosa which ascends rivers for a considerable distance, L. ochracea is restricted to the lower regions of streams. In view of the fact that it is found only in waters directly con- nected with the ocean, it may well parasitize the alewife or some similar migratory fish. Distribution. Simpson (1914, p. 49) gives the range of this species, as "the Atlantic drainage from New England to the Ogeechee River, Georgia." Simpson's record from the Ogee- chee River was based on Lea's U. crocatiis^Nhich. he placed in the synonymy of L. ochracea; however as U. crocatus is not 154 OCCASIONAL PAPERS ON MOLLUSKS this species, the most southern authentic record of ochracea is from the Savannah River, Georgia.

North Carolina: Lake Waccamaw, Columbus County (MCZ); Roanoke River, Weldon (USNM). Georgia: Savannah River (MCZ and USNM). Remarks. Though L. ochracea has often been confused with L. cariosa they are quite distinct. In general L. ochracea has a thinner, smaller shell and unlike L. cariosa which is rarely rayed, L. ochracea is often rayed over the entire surface of the shell and has a rougher, duller, more greenish periostracum. The hinges are quite different: the pseudocardinals of L. cari- osa are pyramidal, and a narrow interdentum is present, but in L. ochracea the teeth are lamellar and almost parallel to the hinge line and there is no interdentum. Frierson (1927, p. 68) claimed that DeKay (1843, pi. 19, figs. 237, 238) correctly figured L. ochracea, but I am inclined to OCCASIONAL PAPERS ON MOLLUSKS 155 Plate 21. Distributional patterns of Lampsilis cariosa Say and Lampsilis ochracea Say in Eastern North America. The circles in- dicate the distribution of L. cariosa and the triangles the distri- bution of L. ochracea. 156 OCCASIONAL PAPERS ON MOLLUSKS agree with Ortmann (1919, p. 292) that the figures represent L. radiata Gmelin. Simpson (1914, p. 50) placed Unio crocatus Lea in the syn- onymy of ochracea, but from an examination of the figured type, USNM no. 84908, here selected as lectotype, it appears to be closer to Lampsilis constricta Conrad. Frierson (1927, p. 68) points out that Unio troostensis (Conchologia Iconica 1866, 16, pi. 38, fig. 210) non Lea, doss not represent L. ochracea as thought by Simpson (1914, p. 50) but is Nodularia aegyptiaca Cailliaud. Frierson (1927, p. ^'S) places Unio boydianus Lea in the syn- onymy of Lampsilis ochracea but the figured type, USNM 87126, here selected as lectotype, reveals it to be a young speci- men of Lampsilis siliquoidea Barnes.

Clench and Ruth D. Turner In this report we consider the genera Triincatella, Geomel- ania, Blandiella and Taheitia as members constituting the family Truncatellidae. The genus Cecina A. Adams, generally considered a member of the family Truncatellidae, belongs, in our opinion, to the family Amnicolidae. We have a cotype of Cecina manchurica A. Adams (MCZ 178837) and this specimen has all of the char- acteristics of a member of the latter family. It is dark green in color, devoid of sculpture and is truncated as the result of corrosion rather than mechanical stress. The radulae of the genera in the Truncatellidae have a cen- tral tooth which is triangular, thus differing, so far as we can determine, from other closely allied groups which usually have the central or rachidian tooth subquadrate in outline. Also the adult shell is generally mechanically truncated. This, at first, may seem a superficial character, but nevertheless it has re- sulted in a definite pattern of profound structural changes in the shell. The loss of the early whorls necessitates the forma- tion of a septum, a rounded and concave plug, in the region of the mid-whorls. Fracture of the early whorls takes place along the outer margin of this septum where it joins the side of the shell. The point of fracture is remarkably constant for any one species, though the number of whorls remaining may vary from four to six or seven, depending upon the species. This is not in any way to be confused with the corrosive 157 158 OCCASIONAL PAPERS ON MOLLUSKS effect of certain environments which causes the loss of a few of the very early whorls in many freshwater gastropods. This, of course, stimulates the individual to wall off this area with a lime deposit to prevent any subsequent exposure of the soft parts. In the case of members of the Truncatellidae there is a definite reaction when the animal approaches maturity and at this time the plug is formed and the subsequent fracture takes place. It is probably equivalent to the reaction which causes a gastropod to produce a lip on the adult shell, a reaction re- markably different from the one that is responsible for the forward-growing shell structure. The genus Truncatella is widely distributed in the tropical and south temperate coastal regions. In a few areas, notably coastal Europe, it survives beyond these limits. The genus, however, is not present everywhere within its range even when ecological conditions appear favorable. It is sporadic in occur- rence and usually exists in isolated colonies. This is probably due to the rather hazardous niche in the environment that they attempt to occupy, namely, the region just below high water line. Becoming established by means of flotsam, a colony flourishes for a time, builds up a population and then suc- cumbs or is scattered by a storm. There appear to be other limitations to its distribution, principally the ability to survive a long journey at sea. So far as we can trace it, the genus has never reached the Hawaiian Islands, nor any other island group in the central Pacific to the east of the Society Islands. In the Eastern Pacific, Truncatella has been recorded only between southern California and Panama. In the Western Atlantic, it occurs from northern Florida south to Trinidad. Though an occasional colony has been found north of Florida, such an occurrence appears to be sporadic. We are deeply indebted to R. Humes, D. Thaanum, J. R. leB. Tomlin and T. van der Feen for the gift of much valuable material in this family. To C. G. Aguayo, J. Armstrong, C. M. Cooke, C. Guthe and H. A. Rehder we are grateful for the use of the collections under their charge. These collections com- bined with our own represent well over 2000 lots, approxi- mately 75,000 specimens. This has made possible a far better understanding of the family and its complexities than if we OCCASIONAL PAPERS ON MOLLUSKS 159 had depended only upon our own material and such data as we could glean from the published record. Much is still unknown about this family, particularly regard- ing the genus TriincateUa. Field studies are very important and attention is directed toward the variation and extent of costation within single colonies. Nothing, so far as we have been able to determine from the literature, is known about their life histories, such as length of life, breeding habits, mode of dispersal and many other factors that are important to an understanding of geographical distribution.

In Truncatella, only the synonymies of a few of the Indo-Pacific species are given. We have considered elsewhere the species occurring in the Western Atlantic {Johnsonia 2, pp. 149-164, 1948). In the catalogue at the end of this report, however, are listed all of the published names that we have been able to trace in the Truncatellidae. 160 OCCASIONAL PAPERS ON MOLLUSKS Plate 22.

The greatest differences appear to be in the shape of the ra- chidian teeth and the number of denticles these teeth support on the mid portion. Comparisons between the few species that we have examined in the genus Truncatella show no specific differences in the structure of the radula (T. pulchella, T. bilabiata and T. guerinii). The only radular figures of Taheitia that we have seen are those of I. Rensch (1937, pp. 627-630). The rachidian teeth are incompletely drawn and we believe rather inaccurately as to detail.

This is a dimorphic species, the extremes being strongly costate and completely sm^ooth. As a consequence a host of names have been employed, not only designating these forms but also as a result of the wide geographic range of this spe- cies. Differences certainly exist between the two extremes, but there are often connecting forms in a series from one locality. For convenience, the name teres Pfeiffer can be retained for the strongly costate forms, marginata Kuster for those that are nearly smooth and pelliicida Dohrn for those that are small 164 OCCASIONAL PAPERS ON MOLLUSKS and entirely smooth. Geographically there is a slight size dif- ference, but from one locality, the specimens are all approxi- mately the same size. Different localities may show a size difference of nearly 2 mm.

It would appear to be quite rare even though widely distrib- uted. See also remarks under T. granum Garrett. We have seen specimens from the following localities: Uvea (Wallis Island); New Caledonia; Zanzibar; Mombassa, Kenya, East Africa. So far as we can determine, T. futunaensis Mousson is only a rather large T. rustica. OCCASIONAL PAPERS ON MOLLUSKS 165 Truncatella (Truncatella) kiusiuensis Pilsbry Plate 25, fig. 5 Truncatella kiusiuensis Pilsbry 1902, Proc. Acad. Nat. Sciences Philadelphia 53, p. 615 (Tane-ga-shima, Hirado Hizen, Japan). This species is very close to T. rustica Mousson, differing mainly in that the parietal margin of the lip is in close attach- ment to the body whorl with no indication of a gap. We possess specimens from Tane-ga-shima, Awaji and Tsushima-Iki, Japan. Truncatella (Truncatella) granum Garrett Plate 25, fig. 4 Truncatella granum Garrett 1872, American Journal Conchology 7, p. 225 (N. E. end of Taviuni Id., Fiji Islands). This is a very small species, about 4^ mm. long, possessing a duplex lip, a rather strong basal ridge and having a very thin calcareous plate on the operculum. There are about 28 rather narrow and low axial costae on the body whorl. This species differs quite noticeably from T. rustica Mousson by its much smaller size, finer and more delicately formed costae and, especially, in the type of the duplex or bilabiate lip. In rustica the lip is a simple duplex formation. In granum, however, it actually consists of a strongly developed outer lip, and an inner lip consisting of a series of "nested" aperture margins. This actually causes the aperture to become smaller during late adult life. Truncatella (Truncatella) thaanumi, new species Plate 25, fig. 6 Description. Shell about SV mm. in length. Whorls 4.^ and moderately convex. Color a pale straw-yellow. Aperture small but surrounded by an exceedingly thickened duplex lip with a broad parietal gap. Basal ridge remarkably developed, so much so that it appears below the aperture and merges into the duplex lip. Sculpture consisting of about 20 strong axial blade-like costae which pass over the basal ridge. Operculum with a rather thin calcareous plate. 166 OCCASIONAL PAPERS ON MOLLUSKS ngth 5.5 width 2.4 mm. Holotype 6.2 2.8 Yap Island, Caroline Islands 5 2.2 Na Islet, Ponape, Caroline Islands Types.

We have examined type material of the following species: concinna Pease; ferruginea Cox; guerinii Villa; pacifica Pease; valida Pfeiffer; vitiana Gould; and yorkensis Cox. Remarks. This is an extremely widespread species in the Indo-Pacific area. Like most other species of Truncatella, it is subject to considerable variation in size, shape and sculpture. This factor has brought about the long synonymy given above. In a large series of this species we have been unable to sepa- rate, either as species, subspecies or even valid races, the many named forms that exist. It is most unfortunate that the better known name of valida Pfeiffer must be replaced by guerinii A. and J. B. Villa.

The axial sculpture, when present, in the form of costae; spiral sculpture seldom present and then consisting only of very fine threads between the costae. The last whorl partially free or adnate. Outer margin of the lip straight or sinuous and sometimes with a small basal extension or with a partially closed sinus near its upper margin. Operculum may be with or without a thin calcified plate on the outer face of a paucispiral chitinized base. In Geomelania s.s., the operculum is thin, paucispiral and consists entirely of chitin. OCCASIONAL PAPERS ON MOLLUSKS 173 Vendryes (1899, p. 605) reports that Geomelania grey ana C. B. Adams, beardsleana C. B. Adams, and pygmaea C. B. Adams possess an external, calcified and rugose plate on the operculum. Vv^e have not seen the opercula of these three species. So far as now known, the genus Geomelania occurs in east- ern Cuba, southwestern Hispaniola, Jamaica and the Cayman Islands. The Jamaican species in this genus have been complicated unduly by C. B. Adams. His collection is now in our possession and, with few exceptions, most of his species were based upon very few individuals. He carried to excess the naming of slight variations, and as few of these forms have ever been figured, his names have remained more or less unknown for nearly one hundred years. Geomelania, particularly the subgenus Geomelania, exhibits considerable variation in the lip structure, especially in the formation of the tongue-like process on the outer lip. The dif- ferences exhibited by many of the specimens named by Adams are due merely to an age factor. In other words, the older the specimen, the greater the degree to which the tongue-like pro- cess has been developed. In addition, the curvature of the sig- moid outline (in profile) of the lip has been intensified. These characters were used by Adams to separate individuals into categories under the heading of different species. Subgenus Geomelania Pfeiffer Geomelatiia Pfeiffer 1845, Proc. Zool.

Operculum paucispiral with a calcified plate on the outer surface which is ridged, the ridges cun^ed and emanating from a common center over the nucleus. The genus Blandiella is known to occur only on the island of Trinidad. In relationship of its shell characters, it appears nearest to the subgenus Merrilliana in the genus Geomelania but it differs in lacking spiral lirae, a character more or less developed in nearly all species of Merrilliana. The radula in- dicates a closer relationship to Truncatella (Plate 22, fig. 1 and 2) than it does to Geomelania (Plate 22, fig. 4 and 5). Blandiella reclusa Guppy is the only known species in this genus.

Shells small, rarely exceeding 10 mm. in length in the adult truncated form. Sculpture consisting of axial costae which are seldom rounded but are most frequently blade-like. So far as known the axial costae always persist over the mid portion of the whorls. No spiral sculpture present. Lip moderately to greatly reflected. Operculum paucispiral with a heavy calcified and rugose plate on the outer surface. The genus Taheitia is closely related to Truncatella', certain of its species, such as porrecta Gould and scalariformis Reeve are very similar to species of Pacific Truncatella. They differ in being more delicate in structure, having the costae finer and blade-like and in possessing a very well developed calcare- ous plate on the outer surface of the operculum. They are strictly terrestrial in habit, though it is interesting to note that the species that most closely approximate the species of Trun- catella are to be found in the lowlands and nearest the sea. Other species of Taheitia, such as arcasiana Crosse, turricula Mousson, both from the Fiji Islands, and alata Quadras and V. Mollendorff from Guam, are quite different from typical Truncatella. In most cases, these latter species have been found in the interior of the larger and high islands of the western Pacific. From the limited material we have had at hand for study, it would appear that the various species are somewhat colonial in habit and scattered in their distribution. We list all the species that are known or are believed to be members of Taheitia. It is quite possible that certain species listed in our catalogue and originally described as Truncatella may eventually prove to be species in Taheitia.

Taheitia arcasiana differs from both cookei and abbotti by having fewer completed costae on the body whorls and in addition, the blade-like structures at the base of the costae are far better developed in T. arcasiana than in either of the subspecies. T. arcasiana differs from abbotti by having the whorls more convex and having a proportionally wider shell. From cookei it also differs by being larger.

He intro- duced this name in the catalogue of the Museum Godeffroy and later considered his species to be the same as arcasiana Crosse. We possess a specimen labeled as a type of Mousson's alternans, received originally from the Museum Godeffroy. It is different subspecifically from arcasiana as described by Crosse. Apparently Mousson had two species, neither of which was arcasiana. The specimens originally sent out by the Museum Godeffroy under the name of alternans were quite different from arcasiana. T. arcasiana cookei differs from both arcasiana and abbotti by being smaller, having more convex whorls and by having the blade-like processes of the costae less developed. Also the parietal gap is far less developed in this subspecies.

In young specimens the spire is slightly concave with the last whorl showing a strongly angled periphery, the costae below being reduced to faint threads. Periostracum dark amber and deciduous, the shell chalky- white underneath. Operculum possessing a striated calcareous plate on a horny base, the calcareous portion being outermost. The striae radiate from the nucleus which is on the parietal margin. length width aperture 9 2.5 2X1.7 mm.

This last locality is based on specimens in the B. P. Bishop Museum no. 88541. Remarks. The reference above by Mousson is to this new form and not to T. arcasiana Crosse as he thought. T. arcasiana abbotti differs from typical arcasiana in having the blade-like portion of the costae far less developed and hav- ing less convex whorls. From T. arcasiana cookei it differs in being larger, less convex and having a much wider parietal gap. Taheitia turricula Mousson Plate 25, fig. 1 Truncatella turricula Mousson 1869, [in] Museum Godeffroy, Hamburg, Cat- alog 4, p. 76 (Mango Island [Lau Group, Fiji Islands] ) [nude name]; Mousson 1870, Journal de Conchyliologie 18, p. 196. OCCASIONAL PAPERS ON MOLLUSKS 189 This species has rather widely separated and strong costae. The aperture, though holostomatous, has a very narrow pari- etal gap. We have seen specimens from Naiau Island, Navutu Iloma Island and Mango Island in the Lau Group, Fiji Islands. All these lots are in the collection of the B. P. Bishop Museum. Taheitia turricula laddi, new subspecies This subspecies is rather closely related to T. turricula Mousson. It differs, however, in its smaller size and much finer and more closely-set costae. There are 26 costae on the body whorl of laddi and only 16 on the body whorl of turricula, and the costae of laddi are more blade-like. Shell white, aper- ture holostomatous with an exceedingly narrow parietal gap. length width 7.5 2.5 mm. Holotype Types. Holotype, B. P.

Taheitia funiculus Mousson Trimcatella funiadus Mousson 1869, [in] Museum Godeffroy. Hamburg, Catalog no. 4, p. 76 (Interieur de Viti Levu [Fiji Islands] ) [nude name]; Mousson 1870, Journal de Conchyliologie 18, p. 197. There is considerable question as to whether or not this spe- cies came from the interior of Viti Levu, the largest of the Fiji Islands. It probably came from one of the islands in the Lau Group. This species is very close in its relationships to T. turricula Mousson and has about the same number of costae on the body whorl. It differs, however, in having the costae a little more blade-like, in its smaller size and its somewhat wider parietal gap. 190 OCCASIONAL PAPERS ON MOLLUSKS Taheitia soluta, new species Plate 23, fig. 4; Plate 24, fig. 5-6 Description. Shell reaching about 9 mm. in length, truncated and rather coarsely sculptured, rather thin and imperforate. Whorls six and only slightly convex. Color whitish to gray. Aperture holostomatous, auriculate to subovate, with a moder- ately reflected lip. Aperture built forward producing a pro- nounced parietal gap. Last whorl solute, free for about one third of a whorl. Sculpture consisting of numerous very thin blade-like axial costae, all more or less uniform in structure but varying slightly in spacing, particularly on the mid whorls. There are 15 costae on the body whorl. No spiral sculpture visible. Operculum paucispiral with a very strongly developed calcareous plate. The calcareous portion consists of blade-like costae all evolving from a common point which is built up as high as the aperture is wide. The high point is more or less over the nucleus. length width 9 2.5 mm. Holotype 9.1 2.6 Paratype 8.1 2.4 Types. Holotype, B. P. Bishop Museum no. 179895, Bavatu, Vanua Mbalavu, Lau Group, Fiji Islands. Paratypes, Museum of Comparative Zoology no. 157754 from the same locality. Remarks. This species is probably distantly related to tur- ricula Mousson from which it differs by having the costae blade-like and not rounded and having a larger parietal gap with a correspondingly greater portion of the last whorl free. Taheitia tongana, new species Plate 23, fig. 6 Description. Shell reaching about 8 to 9 mm. in length, trun- cated, finely sculptured, rather thin and imperforate. Whorls five and strongly convex. Color yellowish to gray. Aperture holostomatous, auriculate to subovate, with a strongly reflected lip. Aperture built forward, having a definite parietal gap. Spire extended and abruptly truncated. Sculpture consisting of very fine blade-like axial costae, all being uniform. There OCCASIONAL PAPERS ON MOLLUSKS 191 are 37 to 42 costae on the body whorl. No spiral sculpture visible. There is a slight tendency toward forming a basal ridge. Operculum with a calcareous plate, having very strong curved, radial ridges. length width 6.8 2.5 mm. Holotype 7.1 2.5 Paratype 7 2.5 Types. Holotype, B. P. Bishop Museum no. 87703, from inland one half mile from Vaigana, Eua Island, Tonga Islands on cliffs at 760' elevation, H. S. Ladd and J. E. Hoffmeister collectors, May 1928. Paratypes from the same locality, Museum of Com- parative Zoology no. 157757. Remarks. This species appears to be distantly related to Taheitia titrricitla Mousson of the Fiji Islands. It differs mainly by having exceedingly fine and very numerous axial costae. Taheitia clathrata A. Adams and G. F.Angas Truncatella {Taheitia) clathrata A.Adams and G. F. Angas 1865, Proc. Zool. Soc.

OCCASIONAL PAPERS OX MOLLUSKS 193 Catalogue of the Truncatellidae The following catalogue includes all names that we could locate which referred to species and genera in the Truncatel- lidae. Cross references are given to many synonyms in the genus Trimcatella; they are omitted for species in Gcomelania and Taheitia as these genera are outlined fully in the earlier portion of this report. We have used the following abbreviations in order to save as much space as possible in the catalogue. Archiv f. Natur. — Archiv fiir Naturgeschichte C to C — Contributions to Conchology This pubHcation consisted of twelve numbers under the editorship of C. B. Adams. It contained original articles by Adams, Bland and Chitty, as well as the republication of cer- tain papers by Adams that had appeared elsewhere. It was published in New York between October 1849 and November 1852. After the death of C.B.Adams, Edward Chitty published under the same title in Kingston, Jamaica (1853) a continuation which he called No. 1. This we have indicated in our catalogue as no. 1 [13] to avoid confusion. No additional numbers were ever published. Jahr. Malak.

The number of nude names oc- curring in this list indicates that Paetel probably had access to museum collections throughout Germany. As a conse- quence, many manuscript names which he copied from mu- seum labels were included. References are not always given nor are they always to the original citation. It is, however, the most complete list of specific names ever published and it is very important as a source of information, much of which could not be located without considerable effort. Paetel's earlier catalogues, published in 1869, 1873 and 1883, were much smaller and, of course, completely superceded by his three volume work. ijBR*M 'Qccasional Papers On Mollusks 3 0 19^ Published by The Department of Mollusks HARVARD ^ iltt¥ERSlTX Museum ot Comparative Zoolojjy, Harvard Lniversity Cambridge, Massachusetts VOLUME 1 MARCH 30, 1949 NUMBER 14 Jesse Wedgwood Mighels with a Bibliography and a Catalogue of His Species By Richard L Johnson Although Jesse Wedgwood Mighels was active in conchology for little more than a decade before the middle of the last century, he described as new nearly one hundred species of mollusks, most of them from New England and the Hawaiian Islands. Through his efforts the Portland Society of Natural History acquired a collection of mollusks which for some years had few rivals in the United States. Mighels was born in Parsonsfield, Maine on July 7, 1795. He was teaching school by the time he was eighteen. He soon be- gan the study of medicine under the direction of a local phy- sician, Dr. James Bradbury. After attending some "medical lectures" at Dartmouth College, he was awarded the degree of M.D. in 1823. Three years later, Mighels married Evalina A. Rust of Norway, Maine. They lived in Minot, Maine for nine years, then moved to Portland where Mighels won a reputation in surgery. Mighels began the study of conchology in 1827. and it is obvious from the annotated remnants of his library (now in the Portland Society of Natural History) that he spent long hours mastering this science. When the Portland Society of Natural History was formed, Mighels was elected correspond- ing secretary at the first election of oflftcers in December 1843. He held this position until he moved to Cincinnati, Ohio in 1847. Even before the Society was founded, Mighels was collecting shells. At first he valued shells only for their intrinsic be^iuty, 213 214 OCCASIONAL PAPERS ON MOLLUSKS and in accordance with the custom of the time, he wanted only a pair of each species. It was not long before a new light began to dawn upon him: for in reply- to demands for shells made of persons living more or less remote from Portland he was told that shells of his own neighborhood would be accept- able in return. The most that he could do was to gather together a dozen or twenty different kinds of such mean appearance that they did not seem worth the trouble of collecting, much less worthy of acceptance by persons owning large collections of splendid shells. The experiment was made, and the demand came for more. Then, for the first time, he began to understand that a thorough knowledge of the con- chology of his own region was an essential step towards acquiring that of other countries, and it was always the surest and safest method of obtaining the necessary materials. With a boat and a dredge our [Portland] Harbour was fully explored and great was the surprise and pleasure manifested in drawing from their dwelling places numerous living shells of forms and colors wholly new.* In 1846 Mighels sold his shell collection to the Portland So- ciety of Natural History for $1000. It consisted of over three thousand species and upwards of ten thousand specimens, in- cluding all of the species known to inhabit the State of Maine, as well as many "rare and interesting varieties." A year later Mighels moved to Cincinnati, Ohio where he became a professor of obstetrics and diseases of women and children in the Cincinnati College of Medicine and Surgery. It is mentioned in ''Daniel Drake and his Followers" by Otto Juetner that in Cincinnati Mighels "wrote good papers on obstetrics." Since the Cincinnati Natural History Museum was housed in the old College of Medicine Building, it would seem natural that Mighels would have become active in the mu- seum, making the acquaintance of his old correspondent J. G. Anthony; but strangely Mighels' name does not appear on a single record of the institution. It was in Cincinnati that news reached Mighels that on January 8, 1854 a fire had totally destroyed the collections of the Portland Society of Natural History. Upon receipt of this sad news Mighels wrote lugubriously to the Society on Janu- ary 10: * Norton, A. H., 1927: Maine Naturalist 7, no. 2, pp. 67-68.

The work of nine years of delightful enthusiastic industry — is it all gone? . . . Your beautiful collections of shells, and birds, and minerals and fossils — alas, are they all lost? . . . When my eye caught that telegraphic announcement, I was almost af- fected to tears. It cannot all be replaced. How is it possible to replace the deep water species of Maine and the Gulf of the St. Lawrence? The species from Europe, East and West Indies, Sand- wich Islands, from the Nile, India, Africa, South America and Oregon? What a loss! Money and books and goods and buildings can be replaced but that collection, I fear never! ... I have but few specimens of anything. There are a few species of Brit- ish fossils in my possession of much value. To these you are welcome, as soon as the spring opens.* Sometime before 1857, when Mighels was leaving a dimly lighted court room where he had been serving as a witness, he plunged down an open shaft or stairway and sustained in- juries from which he never fully recovered. In 1858 he returned to Norway, Maine, his wife's birthplace, where he remained until his death on September 16, 1861. Mighel's first contribution to conchology was a list of the shells of Maine printed in 1841. Two hundred and seven spe- cies are enumerated, sixteen of which are nude names. Five of these were described the following year with C. B. Adams in the Journal of the Boston Society of Natural History. In this paper twenty-four species are clearly described and adequately illustrated with figures drawn by Mighels. It is interesting to note that in his ''Catalogue of the Shells of Maine" (1843, Bos- ton Journal of Natural History 4, p. 308), Mighels has dropped the name of C. B. Adams as co-author, stating, after due thanks to Prof. Adams that his name had been placed on the paper as co-author through an error of the editor. In Mighels' paper describing fifty-one shells, most of them from the Hawaiian Islands, the descriptions are very brief and none of the species is figured, with the result that the iden- tification of some of these species has been difficult or impos- sible. Where we have had authentic type material a lectotype has been selected and the lectotypes of those species that were * Norton, A. H. 1927: Maine Naturalist 7, no. 2, p. 69. From the Portland Tri-Weekly Advertiser, February 24, 1854. OCCASIONAL PAPERS ON MOLLUSKS 217 not figured by Mighels are herein figured. In a few instances, where no types could be found, neoholotypes have been chosen on the basis of subsequent identification. Unfortunately, Mighels' own set of types was destroyed in the Portland Society of Natural History holocaust of 1854. Mighels did, however, send types of many of his species to the Boston Society of Natural History, to Prof. C. B. Adams of Amherst College, and to J. G. Anthony. All of these types are now in the Museum of Comparative Zoology. Mighels sent types of a few of his species to Dr. J. C.Jay, whose collection is now in the American Museum of Natural History in New York. Unfortunately, in a rather extensive search for this ma- terial we were able to find only one of these type lots. There are types of some of the Hawaiian species in the Cuming Col- lection, now in the British Museum, and L. Pfeiffer described several species which had been sent to Cuming under manu- script names. The late Dr. C. M. Cooke, Jr. generously offered the following notes regarding the localities of Mighels' Hawaiian species: Undoubtedly Mighels obtained a large part of his Hawaiian material from the Reverend Edward Johnson, a keen shell collector, who for many years (from 1837) lived at Waioli near Hanalei on Kauai. Wesley Newcomb and one or two other authors* also had material from Johnson. There is a note on page 18 of the B. P. Bishop Museum copy of volume 2 of the Proceedings of the Boston Society of Natural History, in the hand of William Harper Pease which says: "The marine species were from Kauai without doubt." (Mighels attributes most of them as coming from Oahu). ACKNOV^^LEDGMENTS The author is especially indebted to the late Dr. C.M.Cooke, Jr. of the B. P. Bishop Museum for generously contributing much information regarding many of Mighels species and for checking the identification of most of the types of the Hawaiian species. Thanks are extended to Mr. Ralph Dury, Director, * C. B. Adams received material from Johnson. 218 OCCASIONAL PAPERS ON MOLLUSKS Cincinnati Museum of Natural History; to Miss Ethel L.

This species was first described as H. setigera by A. A. Gould. Apparently Dr. Mighels suggested to Dr. Gould that as setigera was a homonym, hystrix be used. It was under this name that material was sent out and Pfeiffer was the first to publish its use.

This is unfortunate because Miss Neal (1934, P. B. Bishop Museum Bull. 125, p. 39) recognized 22 varieties of Pleuropoma laciniosa Mighels on the basis of A. A. Gould's identification of this species, but Gould's ma- terial was from J.P.Couthouy, collected on the United States Exploring Expedition, and is not identical with the species described by Mighels. Therefore, Pleuropoma laciniosa (non Mighels) Neal becomes a new species with the specific name chosen from one of the varieties.

Any of our subse- quent studies on C. B. Adams will refer back to this list or references will be given again in brief. Papers privately published by Adams were limited in the number of copies and as a consequence are rarely obtainable today. Complete copies of his ''Contributions to Conchology" are seldom offered by second-hand book dealers and even odd numbers of the twelve issued by Adams are infrequently offered for sale. For this reason, all of the original descrip- tions of Adams are published in full in this present report, making it possible for those not in a position to consult the originals to have at hand the complete story of each species described as well as figures of the type specimens never pub- lished by Adams.

Appendix F. Shells, pp. 253-255. Original Descriptions of the Western Atlantic Marine Molliisks Described by C. B. Adams The many descriptions by Adams vary greatly in their com- pleteness. When several specimens of a species were involved, he drew upon all of them for his diagnoses. His measurements, however, were based upon a single specimen. In general, he measured to one-hundredth of an inch. This is a little difficult 248 OCCASIONAL PAPERS ON MOLLUSKS to understand as no attempt was made to give a range in size nor to set aside the specimen measured to be the holotype or "specimen selected" to represent the species. In our selection of lectotypes* we have attempted to locate the single specimen that Adams measured. In many of his type lots, no such speci- men now exists. It would appear that certain of these speci- mens at least were subsequently sent out on exchange. Many of the types are imperfect shells. These represent the single specimens Adams described or the best specimen in a series of poor and beach rolled material. The initials C. to C. refer to Contributions to Conchology. Numbers within brackets in the body of Adams' descriptions refer to the original pagination. The plate and figure references given on the same line as the species name refer to the plates in the present report. Original figures of Adams are also given on our plates, usu- ally twice the original size. In most cases these are the only available figures. Specimens of most of the species described by Mighels and Adams were not in the Adams Collection. All species are arranged alphabetically in the body of this report regardless of the genera in which they were described. However, as far as possible, species are grouped on the plates according to the various genera in which Adams had placed them. abbreviata Adams, Marginella Plate 32, fig. 8 1850, C. to C. no. 4, p. 56.

Mai. 1848, p. 151): "nomine L. divaricatae plures species confusae, omnes di- varicatim striatae." When the types shall have been prop- erly distinguished, we believe they will be found to have the ordinary restriction both in time and in area. The Linnaean 256 OCCASIONAL PAPERS ON MOLLUSKS name should be reserved for the Mediterranean species, since Linnaeus assigns his shell to a Mediterranean habitat. L. eburnea Rv., from the west coast of tropical America, resembles this species more closely than does any other Atlantic species, but differs in having a more distinct and cordate lunule, and in having the striae more arcuated.

C. concinna however is with difficulty referred to the same generic type with C solida and C. conica, being eminently distinguished 268 OCCASIONAL PAPERS ON MOLLUSKS by its smoothness and translucency, (in this respect resem- bling, as also [71] in color, Pupa ovata, P. milium, &c.) and its broadly ovate form elegantly rounded below and acute above, with the same beautiful outline repeated in the aper- ture, as in some Phasianellae. The last two species have a striking coincidence in the general plan of sculpture, reflec- tion of the left side of the lip, &c., and evidently belong to a restricted natural group, which perhaps should be sepa- rated from Cingula. We have been unable to obtain more than one specimen of each of these species. Jamaica. conica Adams Eulima Plate 36, fig. 7 1850, C. to C. no. 7, p. 110.

Shell solid, much distorted, moderately inequivalve in the first stage of growth, afterwards very inequivalve, inequi- lateral; anteriorly well rounded, with the other margins sub- rectilinear, posteriorly and interiorly acuminate: whitish, with unequal often confluent bright red rays, which are in- distinct in the first stage of growth: with concentic blunt edged unequal ribs which are more irregular in the last stage of growth; with both valves sculptured alike in the first stage of growth, but in the second, the small valve is only striated: beaks prominent, slightly involute: umbones flattened, with a strong posterior angle: teeth rather stout. Length .42 inch; height .33 inch; breadth .36. The corre- [236] sponding dimensions of a shell commencing the second stage of growth are .4 inch; .26 inch; .17 inch. This species is remarkable for two very distinct stages of growth, with a very abrupt transition from the first to the second. Until a little more than half grown, it is very much like C. Blandiana in the form of the outline, in the sculp- ture, and in having the valves similarly sculptured, and nearly equal. In the second stage of growth, the larger valve increases nearly three times as much as the other, and the growth is abruptly and strongly directed inwards so as greatly to increase the breadth of an old shell. The sculp- ture is more irregular, and on the small valve it is much finer and is covered with a coarse deciduous epidermis. Posteriorly the small valve is deeply set into the larger one. So abrupt is the change from the first to the second stage of growth, that the edge of the umbonial angle in the first OCCASIONAL PAPERS ON MOLLUSKS 275 makes an angle with the edge in the second of only about 115°, and the general form is made very irregular. It is the analogue of C. speciosa, which inhabits the west coast of tropical America. Station. —Unknown. Habitat.— Kingston harbor (Jamaica), along "the Pali- sades," southeast from the city; A.

Emerson, Esq., and my own. Remarks. This shell was found after my return from New Bedford, among a large number of the Turbo obligatus, and Actaeon trifidus, which were brushed into a box from wet planks, to which they were clinging, not far above low water mark. Six specimens were thus found; also four more with the A. trifidus in a parcel of sand from the harbor of New Bedford. Since then I have found a single specimen by dredging a few feet below low water mark in Dartmouth harbor. The middle of the body whorl and the lower part of the upper whorls were brown, but the rest was whitish. I have also received several specimens from P. G. Seabury, Esq. who found them at Tiverton, R. I., in company with the Turbo minutus, Totten, in the sand. It resembles the Jaminia exigua Couthouy, Bost. Journ. Nat. Hist. II. 92, in several important characters but differs in others. The epidermis is dark brown, close, and shining; that of the /. exigua is very pale, nearly white, membranous and loose, and dull; the body whorl in our shell is much less ventricose and more cylindrical; incremental striae plainly OCCASIONAL PAPERS ON MOLLUSKS 285 visible on the [284] epidermis; aperture less; no fold on the columella. It approaches nearly to the Tiiritella bisuturalis Say, which, however, is pellucid, with five whorls, suture not deeply impressed, is more elongate, and whorls flattened. This species may perhaps be referred to Brown's genus Pyramis. Specimens with a revolving line on the upper side of the whorls, may be regarded as a well marked variety. fuscocincta Adams Pleurotoma Plate 30, fig. 6 1850, C. to C. no. 4, p. 62.

A variety of sculpture and coloring has the striae enlarged nearly to the width of the intervening ridges, and is mostly black with spirally elongated spots of white on the ridges.

This species has a slight resemblance to C. minuta, Totten, in the absence of sculpture; but the spire is shorter, more pointed, and its divergence is much greater, giving a very different form to the shell. It is, moreover, a much smaller shell. It appears also to be allied to Turbo reticulatiis Montagu, but is distinct from that species in not having as many turns by one and a half; it differs, also, in OCCASIONAL PAPERS ON MOLLUSKS 303 not being "" strongly striate, both longitudinally and trans- versely," and in not having the "aperture thickened by a rib."

This remarkable and truly beautiful shell is not very nearly allied to any species with which we are ac- quainted, unless it be that of F. fusiformis Valenc, from New Holland. That species, however, is much larger than our shell, is much less regularly and strongly ribbed, and has a tooth-like process on the labium, of which our shell is destitute.

Shell blackish red, conic-cylindrical, with three revolving series of granules; the middle series equally distant from the others, and, on the whorls of the lower half of the shell, of equal size, but diminishing above, and want- ing on the upper fifth; the upper row is less than the lower one on the whorls of the upper fourth or fifth part of the shell, and is wanting upon several of the first whorls; the lower series is also wanting upon the extreme apicial whorls, but, in descending from the apex, appears before the others; the granules are formed by the revolution of two impressed lines across numerous longitudinal ribs or rugae; spire elon- gate, very acute; whorls about thirteen; suture rather broad; impressed, divided by a revolving somewhat granulous black ridge, which in the progress of growth gradually changes its situation, and forms the lower side of the last whorls, and another similar revolving ridge appears in its place; an im- 316 OCCASIONAL PAPERS ON MOLLUSKS pressed line upon each side of the sutural ridge, and two others emergent from the aperture, are continued around the lower half of the last whorl; aperture subelliptical, less than one-fifth the length of the shell; labrum deeply concave; columella prominent below, black; labium regularly arched, surpassing the labrum, notched by the revolving impressed lines; canal recurved, about one third as long as the aperture.

Cabinet of the Boston Society of Natural History, of Dr. A. A. Gould, of Prof. Hitchcock, and my own. Remarks. July 5th, of the present year, I found an im- mature specimen of this species in the harbor of Dartmouth, and at a subsequent visit to the same locality, obtained about two dozen specimens in various stages of growth. This species is easily distinguished from Cerithium reticu- latum, not only by the obvious character of heterostrophy, but by others more important, and too evident to require remark. It is more nearly allied to the C. perversum, Lam., from which it differs in the black sutural ridge, and in the middle series of granules, which in the C. perversum is nearer to the upper than to the lower series. It differs from the Murex adversus of Montague and Turton, {Cerithium adversum, Brown,) in having the canal recurved, the whorls very distinctly defined by the impressed suture, and in the color, which, in the Cerithium adversum, is opaque light brown; the figure of Brown differs also in other respects from our shell. nitens Adams Fusus Plate 39, fig. 17 1850, C. to C. no. 4, pp. 60-61.

This is the only species of true Trochus that has ever been discovered on this Atlantic coast. It is not nearly allied to any species with which we are acquainted, unless we regard Turbo {Margarita) cinereus, Couth.— Tro- chus costalis, Loven, as a true Trochus. A careless observer would be likely to confound them; but besides several other essential points of difference, our shell is easily distinguished from all the known species of Margarita, by the absence of an umbilicus. occulta Mighels and Adams Bulla Plate 32, fig. 13 1842, Boston Journal of Natural History 4, p. 54, pi. 4, fig. 11.

During the summer of 1839, two dredging ma- chines were worked in the harbour of New Bedford. This species was found in the mud thrown up, with several others rarely or never found above low-water mark. Mr. Shiverick has found it at Clark's Cove, in Dartmouth. It resembles Fusus harpularius, but the presence of a very distinct sinus, as well as the coarseness of the revolving striae, readily distinguishes it. [Name changed to Pleurotoma plicosa C. B.

This shell was taken from the stomach of a had- dock, by Mr. Newbegin, a fisherman, in July, 1840, seventy five to one hundred miles off the mouth of Kennebec river, on fishing ground called by the fishermen '' Monhegan Falls/' The water at that place is from forty to seventy five fathoms in depth. Remarks. This very singular and truly splendid species resembles C. noachina Linne, but differs from that shell in the following characters; in C. noachina the ribs are more elevated, the corresponding interior sulci are much more obvious; posterior slope much and regularly curved, shell smaller; proportionately longer, not so high, interior arch without wings.

This species was discovered in September, 1839, in company with great numbers of the Venus gemma, Totten, and many of the Jaminia fusca, Nob. It has a strik- ing resemblance to the latter species, but is much more elongate, has two more whorls, the body whorl is much less OCCASIONAL PAPERS ON MOLLUSKS 329 inflated, and the suture is rather more deeply impressed. proxima Adams Natica Plate 41, fig. 13 1850, C. toC. no. 7, p. 111.

The lectotype is the specimen figured in the Thesaurus.] This species was discovered by me in the bark of a log, on the shore of the Bay of Port Royal, near Kingston, Jamaica, in March, 1844. Specimens were distributed with the Mss. name of P. rosea, subsequently altered to P. corticaria. Some were sent to the British Museum and to Mr. Cuming's col- lection, where they were seen by Mr. Hanley, who affirmed them to be not distinct from a variety of P. pusilla Linn. In deference to his opinion, the description was suppressed from my 'Synopsis' of new species from Jamaica. In part X of Sowb. Thes. Conch. (Dec?) 1849, a description of this spe- cies is published for the first time, with the name of T. cor- ticaria Gray, Mss.,' as being in the British Museum, without indication of habitat. It is said that 'the specimens, having bored in floating mahogany, have taken a reddish color.' This color was derived from the bark of the tree. The shells did not penetrate the wood, and where they were in contact with it, they were distorted, as if unable to penetrate it. Mss. names are not quotable as having the value conferred by authorship, and the name must stand as above. It is un- fortunate that the descriptions of several of the new marine species of shells from Jamaica should have been suppressed, in deference to the eminent authority above mentioned, and distributed with erroneous names. rubella Adams Marginella Plate 32, fig. 4 1845, Proc.

Of this species I found four specimens only, which are all that I have seen. They were found in Dart- mouth, at the village of Ponygansett, four miles southwest from New Bedford. They were about five feet, perpendicu- lar depth, below low water mark, upon single valves of the Pecten concentricus Say, in company with the Nassa hoiata Say, Columbella avara Say and the Nucula margaritacea Lam. The valves of the Pecten, on which they were found, were taken from the bottom by my hands at a venture, when bathing. A dredge would probably reveal more. This species probably belongs to Brown's genus Jaminia, which is nearly allied to his Pyramis, but as descriptions of these genera are not accessible, it is with some doubt that I have referred it to Jaminia. It undoubtedly belongs to the same genus with the Actaeon [282] trifidus Totten, (Am. Journ. Sc. XXVI, 368) but this generic name is appropriated to a genus of naked Mollusca. 342 OCCASIONAL PAPERS ON MOLLUSKS In size and form this shell resembles the A. trifldus, but differs from it in the convex whorls, granulous surface, and revolving lines which are all very distinct and less numer- ous, while in the A. trifldus two or three only are distinct, and the others are nearly obsolete,— in the aperture, which is not angular superiorly, and is more effuse and less rounded inferiorly. It is more nearly allied to Turbo spiralis Monta- gue, Test. Brit. p. 323, but differs in the number of volutions and in the presence of the revolving lines around the rugose surface. In the figure the Turbo spiralis is broader in the middle of its length, but this species is broader below the middle; the aperture is also shorter. I take pleasure in affixing the specific name suggested by Dr. Gould. servile 'C. B. Adams* Krebs Cerithium 1866, Annals Lyceum Natural History New York 8, p. 394 [nude name]. {Cerithium servile C.

Emersonii, but the subsequent examination of numer- ous specimens has satisfied me that the distinctive charac- ters are constant. It differs from that shell in having a large elevated ridge in place of the carina on the upper part of the whorls, and in having three equal ridges in the upper whorls of the spire. The entire want of granulations distin- guishes it from the common type of that species. It is dis- tinguished from the Murex tubercularis of Montagu by the same character. The latter is said to have but three revolv- ing ridges, and is also of much less size than our shell. A number of dead specimens have been obtained by dredging, and Mr. Shiverick has found a few in a fresh condition. [Name changed to Cerithium terebellum C. B.

The type (fig. 6) is badly broken, but has the surface somewhat better preserved, showing pale brownish vinaceous radial clouds on the upper surface of the last whorl, which is minutely striate spirally. The base also has very minute spiral striation. The shape is depressed subglobose, with low convex spire. Whorls about 2i to 3, joined by a distinctly impressed suture. The periphery is flattened and obtusely biangular. The base has a median angle. In the second specimen (fig. 3) the " strains of reddish pur- ple" mentioned by Professor Adams are not visible on the white surface, which is dull and beachworn, showing spiral striation only where protected, in the umbilical concavity. The peristome is thin, and in this shell irregularly broken. The columella is refiexed, with a median point at the termination of a strong but narrow spiral cord which contracts the umbili- cus. The parietal callus is very thin. Diameter 1.1 mm., height 0.7 mm. The reflection of the columella is somewhat exaggerated by reason of the broken outer lip, and consequent rolling of the OCCASIONAL PAPERS ON MOLLUSKS 353 shell towards the left, in order to show the full width of the aperture. The most remarkable feature of the type specimen of this species is the color, which suggests Omphaliiis of the fasciatiis group, which is also somewhat similar in structure of colu- mella and umbilicus. I have not been able to compare young Omphaliiis nearly as small as V. tincta, but the smallest seen do not have the carinate base or such minute striation as V. fmcta, and the apical whorl seem.s larger, though it is not per- fect in those compared.

Remarks. Although this shell is small, its solidity, quite unusual in the genus, forbids the supposition that it is im- mature. It is remarkably distinct from other species in the disparity of the anterior and posterior sides, whose length are as eight to three. It must be regarded as exceedingly rare, three or four years exploration having developed only four or five specimens. variabile Adams Cerithium Plate 37, fig. 2 1845, Proc. Boston Soc. Nat.

This species is remotely allied to P. decussata Couth.; our shell, however, is always longer, aperture nar- rower, and the sculpture less regular and distinct; but it is especially characterized by having the spiral carina far be- low the suture. vitrea Adams Rissoa Plate 33, fig. 1 1850.

Testa turbiniformi, minima, vitrea; apertura maxima, or- biculari, subtus valde indentata, vel umbilicata. 358 OCCASIONAL PAPERS ON MOLLUSKS Shell turbiniform, vitreous, minute, with a large orbicular aperture, either umbilicated or with the umbilical region deeply and widely indented. The form of the aperture would place these shells in Turbo or Margarita. The want of an umbilicus excludes three of the species from the latter. The operculum is un- known; but as it is extremely improbable that thin vitreous almost transparent shells should have solid calcareous oper- cula, we may assume it to be horny, which will exclude the species from Turbo, regarding this genus as best charac- terized by the operculum. The most widely umbilicated species approximates in form to Skenea, and might be mis- taken for a depressed umbilicated species of Helix. In tex- ture, the nearest approach among the kindred genera is in Margarita arctica Leach. From all the Turbinidae known to us, they are however well distinguished by their vitreous texture and rapid enlargement of the whorls, which last character produces a large aperture. The variation [47] in respect of an umbilicus is parallel with the similar variation in Turbo. They are not the young of any larger species, for the first one or one and one-half whorls are distinguished from the following whorls by nuclear peculiarities, as want of sculpture, &c. We are acquainted with the young of all the larger species which inhabit the same localities, and none of them resemble these shells. Most of the specimens were obtained from a pint of sand, which contained 110 species of shells, and which was taken from a surface of three or four square yards of sand beach in a little cove near Port Royal, Jamaica, on the outside of the peninsula. A few were found on the inside of the penin- sula. Of V. megastoma and V. interrupta we obtained sev- eral specimens: of the other species,— one to four of each. Probably all the species are rare.

Japanese text 117 pages; Eng- lish translation 68 pages; 50 plates and 161 text figures. The text figures are included in the Japanese text. Indexed in both Japanese and English. This is an excellent piece of work. The species are beauti- fully illustrated in color from paintings by Sanada and Kato. The text figures consist of many detailed drawings of the radulae, jaws and portions of the soft anatomy. These line drawings are captioned in both Japanese and English. A total of 155 species of Opisthobranchia are considered, and of this number 55 are described as new by Baba. The present work has far greater value than would be in- dicated by the limited area covered. Sagami Bay is located on the east coast of south central Japan, just south of Tokyo. The bay is very wide and open to the south and greatly in- fluenced by the warm Japanese current. Consequently many of the species occurring here have a wide distribution in the tropical portions of the western Pacific and therefore this re- port may well serve as a handbook to workers throughout that region. Unfortunately only a few original citations are given though there is a bibliography included, and most of the species cov- ered in the text are to be found in the various works cited. ^ W. J.

Massachusetts VOLUME 1 JULY 11, 1951 NUMBER 16 Busycon coarctatum Sowerby By William J. Clench For the past 100 years Busycon coarctatum Sowerby has been considered a "lost" or even an extinct species. This in spite of a very excellent colored figure of a live specimen by Petit de la Saussaye. Through the kindness of Mrs. Hugh Branham of Fort My- ers Beach, Florida, we have received two fine specimens of this species. These specimens, and others in the National Mu- seum, were obtained by the shrimp fishermen off the coast of Yucatan, Mexico, on the Campeche Bank which extends north into the Gulf of Mexico from the Yucatan peninsula. In the year 1825, George B. Sowerby published a catalogue of the shells contained in the collection of the Earl of Tanker- ville. This was a list of all the species, some 2500, which were to be sold to settle the estate of the late Earl. In addition to the list of known species, Sowerby described nearly 100 new species, only a few of which were figured. Unfortunately Busycon coarctatum was one of the unfigured species. Just how the Earl of Tankerville obtained this rare shell is not known. No locality was given. In 1852, Petit de la Saussaye published a note on two addi- tional specimens, one in his own collection which he figured and one contained in the collection of Largilliert. It is quite possible that both specimens came originally from Largilliert, as he was in Central America about 1842 and made extensive collections during his trip which included the Peninsula of Yucatan. 405 406 OCCASIONAL PAPERS ON MOLLUSKS It is quite apparent from their notes that neither Tryon nor Dall ever saw specimens of this species and Johnson believed it to be extinct. During the past winter there has been extensive fishing for shrimp on the Campeche Bank in the Gulf of Mexico by Amer- ican fishermen. These boats put into Gulf coast ports to sell their cargo and replenish supplies. Interest on the part of en- thusiastic shell collectors has stimulated these fishermen to bring in and sell the shells that come up in their trawls. Thus, this present species was obtained along with many other rare and interesting specimens. The Tankerville Catalogue is a very rare publication, and as a consequence we include a copy of the original description of Sowerby at the end of this report.

We suggest that the figure of Petit de la Saussaye (Jour, de Conchy. 3, pi. 7, fig. 3) be accepted as the type figure to represent this species, and the type locality to be Campeche Bank, Yucatan, Mexico. One of three specimens in the National Museum possesses the specific data as follows: North Lat. 21°30'; West Long. 90°20' in 16 fathoms, received from Mrs. Gladys Sennott. Remarks. This species shows distant relationships to both Busycon perversum Linne and B. pyrum Dillwyn. To B. per- versum, its relationship is indicated by a similar type of axial coloration, the possession of the fine spiral ridges, the sub- peripheral band and the internal ridges on the outer lip. The coloration and the outer and inner ridges are usually lost in adult specimens of B. perversum. Busycon coarctatum differs from B. perversum by being dextral and by having the whorls very globose and possessing the long and exceedingly narrow siphonal canal. In addition, the shoulder spines or knobs in coarctatum are usually much smaller. B. pyrum and B. coarc- tatum are related by the presence of the outer and inner ridges, and a somewhat similar type of axial coloration. They differ mainly in the area of the siphonal canal which is generally very broad in B. pyrum and very narrow in coarctatum. OCCASIONAL PAPERS ON MOLLUSKS 409 The following is the original description of Busycon coarc- tatum Sowerby (A Catalogue of the Shells Contained in the Collection of the Late Earl of Tankerville, London, 1825, ap- pendix, p. 17).

Collins, London, 311 pages, 88 text figures, 40 colored plates and 32 black and white plates. This is probably the most important general book on the ecology of the sea shore that has appeared in recent years. Though restricted in its scope to the shores of Great Britain, the principles discussed and illustrated apply throughout the world. C. M. Yonge, with his wide field experience and his great interest in physiology has given a breadth of interpre- tation to conditions existing along the British shores which makes the book of first importance to all students of marine ecology. The introductory chapters discuss briefly the history of ma- rine ecology in the British Isles, the plants and animals which inhabit the sea shore, the ocean as a background to life along the shore and the physical nature and formation of the shore. The remainder of the book is devoted to a study of the plants and animals of various ecological habitats, their meth- ods of feeding, survival and reproduction. The selective effect of the environment on the species which can exist within a given locality and the inter-relationships of these species are the dominant themes throughout the book. This may be illus- trated by quoting a few of the chapter titles: "Zonation on Rocky Shores; The Intimate Fauna of Weed and Rock; Sandy Shores; Muddy Shores; Borers into Rock and Wood; Life in Estuaries; and Barnacles and Molluscs of Rocky Shore." Mol- lusks being one of the dominant groups of marine animals, much of the book is devoted to this phylum. The illustrations in this book are unsurpassed, the forty full page colored plates are beautifully produced. The many black and white plates, text figures, graphs and diagrams are a con- stant aid in readily understanding the material in the text. OCCASIONAL PAPERS ON MOLLUSKS 41 1 Although this is not a book for the beginner in zoology, he would glean much from its pages. The factual data, though briefly stated, represent years of study by biologists in all portions of the world. Dr. Yonge gives constant reference to the researches of others and has an interesting way of pre- senting personalities concerned in this research in the history and development of the natural sciences and the growth of the science of Oceanography and Ecology, particularly in the British Isles.— RuTH D. Turner. MacGinitie, G. E. and Nettie MacGinitie 1949, Natural His- tory of Marine Animals, McGraw-Hill Book Company Inc., New York, 473 pages, 282 figures. For one seeking acquaintance with the varied fauna of the sea shore this book should be a real help. It is essentially an introductory text book surveying the phyla from a natural history point of view, stressing the habits and relationships of the animals rather than their anatomy. As much of the book is based on the personal observations of the authors it is writ- ten with a stimulating enthusiasm. Though most of the ani- mals considered are from the Pacific coast of North America, the habitats and habits of closely related forms may be suffi- ciently close so that the book can serve as a guide elsewhere. The many hints regarding methods and techniques of obser- vation are also helpful. The first twelve chapters are devoted to generalized discus- cussions of such subjects as Food, Sense Organs, Lumines- cence, Marine Animal Habitats, Variation and Succession, and Relationships. The remaining chapters are devoted to a sur- vey of the phyla, the length of each chapter depending on the size of the group, its importance and interest. The illustrations in the book though of excellent choice as to subject matter are often rather poorly executed, especially some of the half-tones. The line cuts as a whole are good. 412 OCCASIONAL PAPERS ON MOLLUSKS The chapter on mollusks in which we were particularly in- terested covers 74 pages and in general is a good survey of the group from the limited point of view of the littoral marine habitat. It gives an excellent picture of their general struc- ture, function and mode of life, without being burdened by an enormous number of details and complicated terms. There are, however, several rather basic errors which we believe should be noted. In discussing the structure of the shell the authors speak of a "middle lusterless thick limey layer and an inner pearly lustrous layer of nacre." Both the middle and inner layers are of calcium. The middle layer should be re- ferred to as the prismatic layer as in this layer the calcium is laid down in prismatic crystals. The inner layer should be referred to as the laminated layer because here the lime is laid down in thin layers and may or may not be nacreous. This explains why most shells lacking luster, cannot produce valuable pearls. They also state that ''cowries and related species dissolve the columella or central column of the shell and thus leave a single large cavity without spirals." No group of mollusks completely dissolves the internal whorls: the col- umella must remain for the attachment of the columella mus- cle. So far as we know, most if not all members of the Conidae possess opercula. We wonder where the figures on weights for the Giant Squid were obtained; they seem to be tremen- dously over-estimated. From the specimens of the Teredinidae which we have examined, the siphons are not long proportion- ately as they extend out only a short distance from the base of the pallets. The authors state that they have purposely left out refer- ences to the papers of other research workers from which they have drawn information. This is to be regretted. The bibliography at the end of the book is exceedingly brief and general and it would be a most difficult task to locate the original work if one was interested in so doing. —Ruth D. Turner.

Clench and C. G. Aguayo The present study covers only a few species in this remark- able genus. Members of this complex constitute the subgenus Umbonis Maynard and represent a divergent element, rather strikingly different from other members of the genus Cerion. So far as now known, they occur on the north coast of Cuba and on a few of the islands composing the Bahama Archipelago. The origin of the species in this subgenus was probably the coastal area of Oriente in eastern Cuba. From here they spread west to Pinar del Rio and north into the Bahamas. Their dis- tribution is sporadic and in many cases there are wide areas between species. The habitat they occupy is a precarious one, the upper strand line in the scrub growth, particularly among sea grapes and other associated plants. Their distribution is probably entirely by hurricanes or other severe storms, either by drift or even possibly on wind-blown debris. Similarly to other mollusks that live in this general environment, when established they may flourish for a shorter or longer period of time and subsequently be destroyed by storms. Debris from such a storm may move many miles along a coast or even out to sea, later to be cast ashore elsewhere. Cerion, drifting with this debris, may become established in a new area.

Sculpture consisting of rather irregular, strong to weak, axial costae with spiral sculpture of numerous incised lines which cut into the shell in many cases even over the axial costae. Many members of this complex agglutinate small grains of calcareous sand to areas on the outside of the shell, especially in the umbilical region. Live specimens in many of the species possess exceedingly fine powdery or scale- like sculpture which is most apparent on the later whorls and along the margins of the incised lines.

At this writing the whereabouts of Pfeiffer's types is unknown. They were presumed to be in Stetten, Germany until the war in 1945. The type locality is Gibara, Oriente, Cuba. Remarks. This species was fairly abundant near Gibara dur- ing the early days of Gundlach's trip but it has since become very rare at this locality. Probably much of the vegetation near the town had been destroyed rather early. The spire tapers from the body whorl to form a rather acute apex. Records. Gibara; N.W. of Gibara; Punta Barril, 1 km.

The holotype of Cerion johnsoni Filsbry and Vanatta is in the Academy of Natural Sciences, Philadelphia. A series of three specimens was received by the Museum of Compara- tive Zoology several years ago from the Boston Society of Natural History, originally from Mr. Johnson and probably from the original lot. The holotype of Cerion faxoni Maynard is in the Museum of Comparative Zoology, no. 184649, and a single paratype, no. 10363. The original locality for johnsoni was unknown, then later it was given as Cuba. We here limit the type locality to the coastal area 1^ miles east of the light- house at Mariel, Cuba. Specimens from this locality approxi- mate the size and shape of the original specimens of johnsoni and faxoni. OCCASIONAL PAPERS ON MOLLUSKS 421 Remarks. There seems to be little question that johnsoni Pilsbry and faxoni Maynard are the same species and very probably from the same original lot of material. This species lives mainly in open and rather exposed places on the low vegetation growing among rocks just above and beyond the high tide area. Occasionally a few specimens work back into the higher scrub growth and the sea grape area. It is very possible that the type specimens were collected in Habana from sand originally from the Mariel region. Sand for building purposes is a rare commodity in Cuba and much of it is gleaned from the upper strand line along the Cuban coast. Consequently, much Cerion territory is being destroyed in the vicinity of small towns and at a considerable distance from the large coastal cities of Cuba. Areas much nearer the lighthouse from which we collected C. johnsoni 20 years ago are now destroyed and this form has nearly disappeared from this region. However, a rather vigorous colony still occurs on the west side of the Rio Mosquito, in an area of fair extent, sea grape covered and with much coral rock.

Remarks. In relationship, this species is nearest to C. aciiti- costatum Sanchez Roig from Cayo Megano Grande, Camagiiey. on the north coast of Cuba. It differs from this species in being far less conic (from the body whorl), and by possessing more numerous costae. It does not appear to be closely related to C. tiinierac Clench and Aguayo from the north coast of Great Inagua. This last species is a little smaller, has more globose whorls and much fewer costae. C. rehderi, so far as now known, is limited to this single locality on the south shore of Great Inagua. It was found as- sociated with C. dalli Maynard, with no indication of any hy- bridization between the two species. In fact, this is one of the few known cases in which two separate elements of Ccriofi are known to exist in the same area without crossing. This species is named for H. A. Rehder, Curator of Mollusks in the United States National Museum. Cerion (Umbonis) turnerae, new species Plate 53, fig. 4^7 Description. Shell small, reaching about 15 mm.

Nuclear whorls smooth and then finely ribbed and with a little trace of spiral sculpture. General color a dull gray to faintly purplish, both axial ribs and minute spiral ridges whitish. Early three whorls forming an angle of 44' , later whorls nearly straight- sided. Aperture subcircular, holostomatous and more or less evenly flaring and slightly projecting beyond the body whorl. Mid-parietal wall supporting a well-defined tooth, columellar tooth absent. Lip flaring, simple and not developed into a col- lar. Suture indented but not well-defined.

McLean, Shreve and Bartsch found it along about a 12 mile stretch of coast from Canfield Bay to near North East Point. In general structure it appears to be nearest in relationship to C scalariniim Pfeiffer from Gibara, Cuba. It does not ap- pear to be at all closely related to C. rehderi Clench and Aguayo, the only other member of the subgenus Umhonis on Great Inagua. This species is named for Ruth D.

This species is remarkably uniform in both shape and size. It is very possible that it is a hybrid element which has reached some sort of stability in both form and structure. The differences are rather marked between this form and johnsoni which exists on the opposite side of Boca de Mosquito. It is possible that repeated introductions of johnsoni have brought about profound changes in the original Cerion stock at this limited locality. To the east of Boca de Mosquito the johnsoni characters become less and less pronounced, partic- ularly in the reduction and extent of the incised lines and the less straight-sided appearance of the early whorls.

In relationship this present form is nearest to Cerion victor Torre, a species occurring at the extreme eastern end of Cuba near Cabo Maisi. They differ in that C. victor is somewhat larger and lacks the duplex character of the palatal lip which is usually present in asperum.

Appendix to Records of Walks and Talks with Nature, West Newton. Massachusetts, 10, p. 116. pi. 1. fig. 3-4 (south end of Great Guana Cay [Exuma Group] Bahama Islands). Description. Shell rather solid, reaching about 26 mm. (1 inch) in length, rimately perforate and rather weakly costate. Color probably a dull white or gray (all specimens were dead when collected). Whorls 10^ to 12, slightly convex and slightly offset. Spire extended, the last three whorls being nearly straight-sided, the early whorls forming a somewhat convex cone which is produced at about 39'. Aperture subcircular. Outer lip reflected and slightly turned backward. Parietal lip straight, thickened, but not built forward materially. Colu- mella short and arched. Parietal tooth centered, fairly large but short. Columellar tooth small and very short. Umbilicus rimately formed, short and shallow. Suture well-defined but shallow. Sculpture: first H to 2 whorls glass-like and smooth, remaining whorls faintly and irregularly costate with a few specimens showing fairly strong costae on the body whorl. These number about 17 on the last whorl, though in many specimens they are very irregular and number far less. Spiral incised lines numerous.

In this form there has been a material leduction in the axial costae, certain specimens being nearly smooth. In a measure this species simulates C. pahncri Sanchez Roig from the north coast of Cayo Romano. Camagiiey.

Cerion felis appears to be nearest in its relation- ship to C. stevensoni Dall from Long Island. See remarks under this latter species. Cerion felis is probably a hybrid element that has retained most of the general characters of the scalarinnm complex and yet shows certain characters of C. glans, many colonies of which exist on Cat Island.

Shell rather short and stout, reaching about 29 mm. (about 1 inch) in length, umbilicate and coarsely sculp- tured. Color a dull somber gray. Whorls 91 to 10, nearly straight-sided and irregular. Spire extended, the last 4 whorls of nearly equal width, the earlier whorls abruptly tapering to form an irregular cone, the conic portion produced at an angle of about 90 \ Aperture subquadrate and holostomatous. Outer lip thin and reflected but not turned back. Parietal area nearly straight and continuous as a thin reflected lip, not thickened as a parietal ridge. Columella short and arched. Parietal tooth centered, well-developed and short, columellar tooth incon- spicuous; neither follows back for more than one-fourth of a whorl. Umbilicus fairly large and deep. Suture very shallow and not well-defined. Sculpture: nuclear whorls smooth, white and opaque, next 3 to 4 whorls finely costate, remaining whorls strongly costate, the costae numbering 12 to 13 on the body whorl. Spiral sculpture consisting of numerous and rather tine incised lines that cut in even over the crests of the costae. Surface powdered, particularly along the edge of the incised lines. Agglutinated sand grains numerous and occasionally incorporated into the body of the shell. 436 OCCASIONAL PAPERS ON MOLLUSKS length width whorls 29 15 mm. 10 Wemyss, Long Island, Bahama Islands 25.1 15.4 9 24.7 15.5 10 Types.

In relationship it appears nearest to C. felts Pilsbry and Vanatta from the central area of Cat Island. From felts, this present form differs by being proportionately wider, having coarser sculpture and being openly umbilicate. Records. Bahama Islands: Wemyss, 7 miles S.E. of Simms, Long Island (MCZ).

Additional paratypes in the Museum of Comparative Zoology, the Museo Poey, the United States National Museum and the Museum of Zoology, University of Michigan. Remarks. This species does not seem to be closely related to any other in the scalarinum complex. The axial costae are fine and numerous, the spiral incised lines are coarse and rather deeply cut into the shell. It is, perhaps nearest to C. palmeri Sanchez Roig, at least in its shell characters. It differs in being less attenuate and in having both the axial costae and incised lines much stronger. Records.

Malacologica "Carlos de la Torre" 6, p. 69, pi. 1, fig. 6 (Cayo Romano (22°24' N.; 76°6' W.) [Cama- giiey] Cuba). Description. Shell rather small and narrow, reaching 19.3 mm. (about f inch) in length, rimately perforate, rather light in structure and finely sculptured. Color a dull and uniform grayish-white to a light straw-yellow, sometimes mottled or marbled. Whorls 10^ and slightly convex. Spire extended, tapering moderately from the body whorl to the first three whorls, these latter forming a rather rounded summit. Aper- ture subquadrate.

Columellar tooth small and rather inconspicu- ous, extending within for a full whorl. Umbilicus rimately formed and very small. Suture slightly indented. Sculpture: first 1' whorls smooth, remaining whorls with numerous, exceedingly fine and slightly oblique costae which become rather obscure on the bjdy whorl.

Long. 76^60; collected by R.H.Palmer. Remarks. This is the most diminutive species in Umbonis on the Cuban coast. It represents a reduction in size and in all sculptural characters. In relationship it is probably closely allied to C. aciiticostatiini Sanchez Roig, the relationship being more real than apparent. Cerion acuticostatnm is a strongly and axially costate shell while pahneri is nearly smooth. Notes The two following species are not members of the subgenus Umbonis but are included here as both possess the spiral in- cised lines. This may have resulted from hybridization with elements in the scalarinum complex at some time in the past. Cerion glans scalarinoides Plate Cerion glans scalarinoides Plate 1907.

This species is in the glans complex but does possess a series of rather deeply incised spiral lines. In this case it may mean that there has been an introduction of some 440 OCCASIONAL PAPERS ON MOLLUSKS scalarinum element, possibly from Great Exuma Island, which has completely integrated with the original Cerion on Green Key, the evidence remaining being these incised lines. This same possibility has apparently produced the occurrence of in- cised lines on two Cuban species which exist in the vicinity of scalarinum elements.

Remarks. This species was based upon a series of "fossil" shells. According to Maynard, he collected these in the red earth of a cultivated field and all may be quite recent. Two specimens show traces of spiral lines. Very probably these are the remnant of a hybrid colony, possibly a cross between the scalarinum element and a member of the glans complex.

In this work he was ably assisted for many years by his col- leagues, Isobel Bennett and Elizabeth Pope, upon whom fell much of the burden of producing the completed volume, and to whom full credit must be given for its excellence. Although the subject matter is designed to meet the needs of the many people whose interests draw them to the seashore, students of Australian malacology will find much to reward them in this book. Mollusks were Professor Dakin's first love, and of the last section of the book which describes the animals and plants of the seashore, no less than 96 pages and 29 plates are devoted to the common species of mollusks. Those of the Victorian and New South Wales coasts are emphasized, and most are illustrated by superb photographs, together with de- tailed and accurate information on their distinguishing char- acters, distribution, and habits. The second printing corrects the few errors which were found in the first edition. Malacologists may consider it un- fortunate that the authorities are not given for species names. However, adequate references are given and the book is not meant to be a systematic handbook. The wealth of detail about the ecology, habits and importance of the Australian mollusks makes it a valuable reference for students, both amateur and OCCASIONAL PAPERS ON MOLLUSKS 449 professional; all will find much pleasure and knowledge in Dakin's delightful descriptions of the seashores which he knew and loved so well.

This report is particularly important in that it is the first attempt to bring together in a single catalogue the entire mol- lusk fauna of Brasil. The catalogue is arranged systematically, giving the date of publication for each species and the known distribution. No references are given under the species but the date following the author's name allows one to find the original description by referring to the excellent bibliography. The author appears not to have seen most of the recent papers as the date of the latest paper listed is 1940. This, of course, means that many additions and corrections are necessary on the basis of more recent work. However, this is usually the case when a work of such scope is undertaken for the first time.— R. D. Turner. 450 OCCASIONAL PAPERS ON MOLLUSKS INDEX The index that follows does not include all of the names covered in this volume.
