NEW JAMAICAN UROCOPTID.E.
BY HENRY VENDRYES.
Cylindrelht (A now a) inusitata, Vendryes. PI. I, tigs. 1 and 2.
Shell much elongated, cylindrical, rimate, somewhat shining and transparent, color light brown ; spire slightly tapering both above and below its greatest diameter, which is about the middle ; truncate with the loss of 7 to 8 whorls, whorls remaining 11 to 12, planulate, shouldered by an early obsolete angle, the last detached and descending, strongly carinated at the base, the carina extending to the back of the aperture ; striae waved, strong and compact, cross- ing the whorls obliquely and continued up to and many crossing over the edge of the suture, which appears fringed here and there by their intrusion ; aperture like that of Dunkeriana, but rather larger in proportion to the shell, and less oblique than in that species, well produced over the penult, whorl. Height 18 mm., greatest breadth above the middle of the spire, 3£ mm.; aperture, 3 mm. high, 2^ mm. wide.
This species is remarkable for its produced and detached aper- ture, placing it in the same group to which princeps belongs. Specimens were received from Mr. Bancroft, who collected them on the mountains at Upper Leighton, near Spring Garden estate in the parish of Saint George.
CylindraJla (Anuma) coynata, Vendryes. PI. I, figs. 3, 4.
Shell rimate, cylindrical, elongated, color very light pale brown ; spire tapering from the last whorl to the summit ; apex truncate, with the loss of 7 to 8 whorls, whorls remaining 11 to 12, subplan-

ulate, slightly shouldered, the last detached and descending, strongly carinated at the base, carina continued to the back of the aperture ; striae very strong and compact, irregularly spaced and waved here and there, t-ome crossing over the sutures from one whorl to the other ; aperture as in inusitafa, but less elliptical, well produced be- yond the penult whorl. Height, 1 "» mm.; greatest breadth, 3 mm.; aperture, 2^ mm. high, 2^ mm. wide.
I am indebted for specimens of this shell to Mr. Hart, at one time Superintendent of Public Gardens and Plantations in Jamaica, and now occupying a similar position in Trinidad, by whom they were collected tit the government cinchona plantations in the mountains of Saint Andrew, about 5,500 feet above sea level.
One of the specimens being alive, I obtained the radula, but failed in securing the buccal plate. The teeth are of the type common to MM. Crosse & Fischer's first group A. of Cylindrellre. The animal is very small in proportion to the shell. It is spiral behind the man- tle, short, of a pearly-white color, slightly mixed witli green, and marked with close-waved, narrow, longitudinal brown lines, not ex- tending to the lapping of the foot; head short, with a simple labial appendage, apparently incapable of much projection ; eye peduncles short, slender, of a deep bistre color, except on the lips, where the color is like that of the body; eyes very black, placed on the bulb- shaped tips of the peduncles ; tentacles short and very slender ; foot broad ami lance-shaped behind. The animal is very active for a Cylindrella. Ir progresses by extending forward the forepart of the foot and drawing the afterpart up to it in a sort of wave. Part of the shell drags lightly on the ground and is carried forward with each fresh advance of the foot.
OyUndrella (Anoma) propingua Vendryes. PI. 1, figs. 7, 8.
Shell rimatc, cylindrical, nearly white, under a light brown epi- dermis, which becomes paler towards the apex; the spire widens very gently from the base of the penult whorl to about one-third above it, where the greatest diameter is reached, and thence it tapers to the truncate apex ; apex truncate with the loss of 8 to 9 whorls, whorls remaining 10, less deep and less flattened than on Dunkeriana, the first two above the base subangular about the periphery, the last more strongly carinated than in Dnnkeriana, with the carina continued down to the base of the aperture ; striae very strong, compact and

wavy, extending across (lie \vliorls to tlrj very edge of the well- impressed suture; aperture oblique like that of Duiikeriana, but the peristome is thinner and is appressed above to the penult whorl. Height 13 mill., greatest breadth at the slender part of the spire 3 mill.
The shell comes near to Dunkertana, but it has 10 whorls which are less planulate than on that species, and the striation is rather coarser and less regular ; the color of Dunkeriana is also different. Gloyne, in Journ. de Couch., vol. — , reports it as siniilis from Belle- vue. Bland had identified them with great doubt as siinilis. On closer examination they turned out to be unlike siniilis or any other Jamaican species of Anoma.
Hab. : Bellevue, near Stony Hill, in the. parish of Saint Andrews, (!) Vendryes. (!) Gloyne.
Oylindretta (Tliaumasia) sanguinea Pfeitler, var. perplexa Vendryes. PI. I, figs. 11, 12.
This variety was collected at(!) Water House, an abandoned sugar estate, now turned into a grazing pen and negro provision grounds, in the upper northern portion of the Liguinea plain, \\here the lime- stone hills of the Rod Hills range, begin to rise. The aperture is produced and the peristome is detached all round ; whilst in the typical sanguined the peristome above is closely soldered to the body-whorl, and often so much attenuated at the point of attachment as to form a thin film. The shell is of medium size and .dark colored ; there is a narrow line of a deeper tint than the ground color, but rather dingy, running next to the suture along the lower part of it and extending to within it. This form is very persistent in the locality mentioned.
CylindreUa (Anoma^) ttbnormis Vendryes. PI. I, figs, o, G.
Shell deeply rirnate, cylindrical!}' elongated, color brown with a very slight tint of yellowish-red, shining ; spire broadly truncate with the loss of — whorls, whorls remaining 9, the last and the three fol- lowing it are more drawn out and consequently deeper than the remaining ones, the last is slightly narrower in diameter than the second, the second than the third, and the third than the fourth, thence the remaining whorls become less deep and gradually diminish in diameter to the truncated apex, so that the outline of the shell presents the form of a long, narrow, drawn-out purse, somewhat

bulging about the middle, and thence tapering towards the bottom ; whorls slightly convex, obtusely angulated at the periphery, sculp- tured with strong, thick lamella-like costulae crossing the whorls obliquely, generally curvilinear, irregular in some places and wavy here and there, extending to the very shoulder of the whorls, the last whorl with a prominent carina which extends to the back of the base of the aperture close to the peristome ; suture well incised ; aperture inclining to the right, the plane very oblique, peristome thick, nearly white, smooth and shining, reflected all around, with a very large, strong, elevated knob close over the spot where the columellar lip should merge into the columella, and apparently arched over the space of the entering rima beneath. Total length, 11 mm.; greatest breadth at middle of spire, 3 mm.; next above the aperture, 2 mm.; at the truncation, 2 mm.
This shell was collected by me among tine earth and vegetable debris taken from the roadsides near to Brown's Town, in the parish of Saint Ann. Unfortunately, as its presence was only revealed to me when searching this debris some time afterwards at home, no note was kept of the exact habitat and station. It is as yet unique in my collection. It is unlike any species of Anoma with which I am acquainted, and its peculiarities would seem to warrant the creation of a new subgenus, or at least of a special section to receive it. The reasons for this appear to me to be as cogent as were those which led to the creation of the subgenus Chittya for Geomelania sinuosa.
CylindreUa (Thauma&ici) histabilis Vendryes. PI. I, figs. 9, 10.
Shell ovate-cylindrical, solid, rimate ; color dark-sanguineous, not unlike that of some specimens of CyL sanyuinea, but the sur- face of instabih's exhibits in most specimens semi-hydrophanous, more or less wide, transverse patches sparsely and irregularly occurring, and apparently produced by some indistinct lesions of the very thin epidermis; spire describing a well-drawn-out ovate outline; apex broadly truncate with the loss of (J to 7 of the earlier volutions, whorls remaining 7 to 8, almost entirely plane in some examples, or moderately convex in others , subarcuately, obliquely and closely costulate strife ; the last whorl not detached in some examples, and detached and produced in others, and generally more strongly sculptured than the penult and other whorls, with a well-pro-
THE NAUTILUS. O
nounced carina at the base ; suture lightly impressed and submar- gined ; aperture slightly oblique, circular in some examples or trans- versely narrowed in others; peristome slightly tinged with the prevailing ground color of the shell, well expanded all around and reflected, not continuous above, but, attenuated or reduced to a mere film '.md appressed to the body whorl in some examples, or in other? detached and continuous, and produced outward near the upper part of the right side of the aperture and with a sinus or notch on the produced part. Long., 24 to 25 mm.; diam. at middle of spire, 9 to 10 mm.; aperture with peristome appressed, 8 mm. high and wide; when produced and with peristome detached, 6 mm. high, and 6 to 7 mm. wide.
In several of its characters this species is rather inconsistent. In specimens found side by side and manifestly of the same brood, some examples show strong affinities with Thaumasia sanguined, others with Thaumasia cylindrus, others again with Gongylostoma lata (? Thaumasia lata), in so fur that it becomes often very difficult to locate them decisively.
In the two specimens figured, one has the lip appressed, as in sanguinea ; in the otl'er it is detached and expanded towards the right side of the aperture and bears a notch or sinus. In one the sculpture is decidedly like that of sanguinea, on the other it is like that of cylindrus, but stronger. In specimens with the aperture but slightly produced and the peristome uninterrupted by attenuation and adhesion to the body whorl, or produced and not bearing a sinus, the resemblance to lata is very great.
Habitat : (!) Phoenix Park, near the Monarque in the parish of Saint Ann ; (!) environs of Brown's Town in the same parish.
NOTES ON MESESCHIZA GROSVENORII LEA.
It is now over thirty-seven years since Mr. Lea described this spe- cies, and additional specimens have not been reported. In his Mono- graph of tl:e family Strepomatidse, Mr. Tryon says, in a foot-note page 350, " every specimen examined shows evidence of diseased growth." In the description, the location of notch is stated to be inconstant or wanting. Admitting then that the notch of this species is a de- formity, where should the specimens described by Mr. Lea be placed ? The notch being a deformity, the genus would not stand, because that

is the distinguishing point of tlie genera, like tlie fissure nf Schizos- toma. I am of tlie opinion that Mr. Lea's specimens are young Angitrema armigera Say, for the following reasons : The young of armigera is generally smooth, is fusiform, thin, obtusely conical and of various shades and markings, from a light straw-color to purple, occasionally seven banded while six is common ; the aperture is large and rhomboidal, obtuse longitudinal thickenings are common on body whorl, a light line under the suture is also common in banded and purple specimens, base channel well defined. Polar point of the operculurn well removed from the margin. There is no other species found in the Wabash that has so many points of resemblance ; about the only point of difference is the number of whorls, five to six in the young armigera I have, while Mr. Lea's description says seven.
There are some other species I think must be referred to Angilrema armigera, but additional specimens from other localities are needed to fully determine the identity. — A. A. HINKLEY.
THE SUBSPECIES OF PYRAMIDULA ALTERNATA.
BY HENRY A. PILSBRY.
Pyramidula alfernata knoxensis, n. v.
A more robust, Ia7-ger shell than typical P. alternate, with more widely open umbilicus; dull rusty brown, with comparatively incon- spicuous or much-reduced flame-markings. Whorls 5^, not carinated. Sculpture of fine and even rib-strias, but little weaker on the base, the whole covered with a secondary sculpture of fine wrinkles, partially cuticular, and running a little more obliquely than the rib-stria>. This minute wrinkling is barely visible to the naked eye, but is much stronger than in other forms of P. alternata, and gives the surface a peculiarly dull appearance.
Alt. 11, diam. 23, width of umbilicus G^ mm. (Knox Co., Tenn.).
Alt. 11, diam. 23, width of umbilicus 7 mm. (Laurel Creek Gap).
Alt. 13, diarn. 25, width of umbilicus 7^ mm. (Hazel Creek).
This remarkable race of P. alternata belongs, so far as we know, to the valleys of the western slope of the Great Smoky mountains, extending into the valley of East Tennessee. It was first found by Mrs. George Andrews, in Knox county, Tenn. During the past summer Mr. Jas, H. Ferries found it in Cade's Cove, at Laurel Creek

Gap and Hazel Creek. We saw nothing of it on higher elevations in tlie Great Smokies, the localities mentioned lying below 2000 ft. elevation. In the collection of Geo. II. Clapp there is a single shell from the .las. Lewis coll. labeled "Philadelphia, Monroe Co., Tenn.," probably collected by Miss Law, and measuring: Alt. 13, diam. 24, umbilicus 7i mm.
No intergrades with typical P. alternata, P. </. carinata or /'. a. costata have been observed. It is remarkable for the strong devel- opment of the secondary sculpture, with fine primary sculpture of rib- strife, the unkeeled, capacious whorls, wide umbilicus, and dead, rusty surface. Messrs. Clapp and Ferriss agree witli me in considering this a strongly differentiated subspecies.
The following subspecies of P. alternata are now recognized :
P. alternata (Say).
P. alternata fergusoni (Bid.). N. Y. to Md.
P. alternata rarinotata Pils. Texas.
P. alternata carinata Pils. Pa. to Tenn., in western division ot the Appalachian Mt. system.
P. alternata hioxensis Pils. Knox, Blount and Monroe Cos., Tenn.
P. alternata costata ' Lewis ' Clapp. Grenty Smoky Mts.
P. alternata mordax (Shuttl.). Great Smoky Mts. (?)
The last variety has not yet been rediscovered ; the ^mordax" in collections being referable, so far as I have seen, to a strongly-ribbed form of P. alternata, which has not been named ; and not fulfilling the requirements of Shuttleworth's diagnosis. P. alternata carinata includes strongly angular or keeled, but finely striate shells of the mountainous region from western Pennsylvania to Tennessee. It was defined in my paper on Rhoads' Tennessee shells ; and is not known to occur in the Tenn.-N. C. boundary ranges. I have never seen any true intergrades between P. alternata and P. cumber I andiana. and consider the latter a well-defined species.
There is also a color var. alba Tryon, of P. aJternata (Amer. Journ. of Conch, ii, p. 2G1, and Monog. Terr. Moll. U. S., p. 49). This occurs abundantly in certain localities within the area of typical alternata. Thus in Philadelphia, alba is found along the Wissahickon Creek, while in other localities in this vicinity the ordinary aJternata is found. This color-var. is not really white, but merely albinistic ; it lacks the spots and flames of the typical form. It is also found in Michigan, etc.

GENERAL NEWS.
POLYGYRA THYROIDES SANCTisiMONis n. var. — Spire more conic than in thyroidcs, composed of 5g whorls which are more closely coiled ; body-whorl decidedly more depressed ; umbilicus open. Aperture smaller than in thyroides, transversely elliptical, being much less rounded than in thyroides. Shell rather solid, with opaque cuticle, often more yellow than in thyroides. Alt. 15, diam. 23 mm. St. Simon's Island, Georgia. — H. A. PILSBRY.
HELICOSTYLA CARINATA Lea, and H. DACTYLUS Brod. — In the Manual of Conchology, viii, p. 22, I showed that Lea's Bulimus cari- iidhis is identical with and was published prior to Bulinus dactylus Brod., and consequently should be accepted in place of the latter. This decision must now be reversed, on account of the earlier Buli- mus cnriuolus Perry, 1.811, which preoccupies Lea's name, and which I was not aware of when the ruling was made. — H. A. PILSBRY.
NOTE ON TWO SPECIES OF CANTHARIDUS. — It has not been noticed, I believe, that Bulimus eximus Perry, Conchology, pi. 30, f. 2 (1811), is identical with Cautharidus bad-ins Wood (18 — ), and Bulimus carinutus Perry, f. 1, is C. peronii Phil. (1850). Perry's figures are very good, for him, and quite recognizable. He gives Van Diemen's Land as locality for the former, New Holland for the latter species. So far as I can see, his names will stand for these species H. A. PILSBRY.
AMIMIIHROMUS LJSVUS (Mull.). — In my account of this species in the Manual of Conclioloyy (1900) the "Helix Iseva" of Miiller was called Ampkidromus Isevis. Mr. G. H. Chadwick has called my attention to the mistake, Miiller's word being the adjective Jsevus, left, referring to the sinistral or " left-handed " coil of the shell. — H. A. P.
A NEW TRIASSIO CHITON. — Mr. Otto Jaekel describes (Zeitschr. del- Deutschen geologischen Gesellschaft, vol. 52, 1900, p. 9) a new form from Riidersdorf as Trachyphura triadomarchica. All of the

valves are preserved in place, with fragments of the girdle. The valves lack insertion-plates, and also otherwise have the general characters of the modern Lepift»/>/?itrits, while the girdle is armed with spines \vhich are believed by Jaekel to have been calcareous. The length, without girdle, is about 16, breadth 9 mm. The genus is evidently extremely like Lepidopleurw in hard parts, and so far as the figures and description show, indistinguishable from the recent genus except in the character of the girdle armature. It is quite unlike any of the known Palaeozoic genera. — H. A. P.
PUBLICATIONS EECEIVED.
SYNOPSIS OF THE FAMILY CARIMIDJK AND OF THE NORTH AMERICAN SPECIES. BY WILLIAM HEALEY DALL. PROC. U. S. NAT. Mus. VOL. xxni, PP. 381-392, 1900.— As Tryon and Pils- bry's " Manual of Conchology " does not yet include Pelecypoda, the necessity for monographs giving the latest investigations in system- atic changes is apparent. Students are deeply indebted to Dr. Wm. H. Dall for his recent monographs on several families of bivalve rnollusks, including the Mactracea, Diplodontida?, Leptonacea, Psam- mobiidre, Solenidje, Tellinida? and Cardiida-.
In the bulletin on Cardiidse there are no plates, but there is a bibli- ography followed by a synopsis of the family which includes a " sub- division of the family included as a whole." The " brackish water forms associated with Adacna" are no longer included in this family.
The principal changes in nomenclature of the East American species since Dr. Dall's " Marine Mollusks of the South Eastern Coast," are as follows :
Cardium magnum Born is included under the name of C- (Dfno- cardiitm*) robiistum Solander, which is the older name ; this does not include C. magnum Linnaeus, which Dr. Dall thinks is probably C. (Trachycardiurn) leucostoma Born. In subgenus Papyridea, spino- sitm takes the place of bitllatinn, or bullata, of " many authors but not of Linnaeus," and P. petitianum Orbigny is a synonym of/5, semisul- catum Gray. Liocardium l<zvigatum is a synonym of (,'ardhnn ( Lcevicardium ) serratum Linnaeus.
The West American species include Cardiums found in the Gulf of California and ranging further south. This adds to the number of West Coast species.
10 THE NAUTILUS.
Collectors who have readily detected a varietal difference in the lighter weight of shells sent out as Cardium nuttallii Conrad, may regret that these shells are not recognized even as a variety, but are included in I lie synonym of Cardium (Cerastoderma) corbis Martyn. Card him b/andum Gould is a synonym of C. (Cerastodcrma) caJifor- niensis Deshayes. Cardium (Cerastodermv} ciliatum O. Fabricius ( C. islandicum Chemnitz (a synonym) and Serripes gronlandicus Gmelin are Arctic sea species that are tound on the Atlantic and Pacific shores. Cardium asperxum Sowerby is listed as a variety of the eastern coast Cardium (Pupyridea) spinosum.
Dr. Dall says Carditnn (Lcevicardium) elalum Sowerby " is the largest species of the genus." We have often noted the variation in shape of some uf the large cardiums of the West Coast; he says of these oval and rotund forms that they may possibly be correlated with sex M. B. W.
DESCRIPTION OK A NEW STECIKS OF UNIO FROM THE CRETA- CEOUS ROCKS OF TIIF, NANAIMO COAL FIELD. By J. F. Whiteaves (Ottawa Naturalist, XIV., Jan., 1901). Unio nanaimoensis n. sp. Unin hnbbardi Gabb is stated to be from the Cowgitz coal mine, on Graham Island, one of the Queen Charlotte Is., and probably did not come from Vancouver Island, as originally reported.
NOTES ON SOME LAND AND FRESHWATER. MOLLUSCA FROM FORT CHIMO, UNC.AVA BAY. By J. F. AVhiteaves (Ottawa Nat., X I V., March, 1901). The specimens were collected by Mr. W. Spreadborough in 1896, and comprise Litimata palustrus var. valilii Planorbis arcticns ('* which may be only a synonym of P. parrus,") I'n/rnfa sine era and Pisidium steenbnc.kii. Notices of previous rec- ords of non-marine mollusks of Labrador are given.
ADDITIONS TO THE MARINE MOLLUSCA OF THE BERMUDAS. By A. E. Verrill and Katherine J. Bush. THE Ni DIBRANCHS AND NAKED TECTIIJRANCHS OF THE BERMUDAS. By A. F. Verrill. (Trans. Conn. Acad. of Sci., X., 1900). The additions to the fauna recorded in these articles are mostly from the collection made at the Bermudas in April and May, 1898, by the Yale scien- tific party under Professor Verrill. In the first paper about 80 species are recorded for the first time from the Bermudas, 25 of

them being described as new, among them a new Siphonaria, 6 Eulimcti several Odostomia and Ccecvm. In dealing with the Ter- bonittidce, the groups Mnmlola and ]\ formula (Adams, 1804) are sub- ordinated to Pyrgostelis (Monterosato, 1884), though Adams' names have priority. The dentition of Syiictptocochlea picta is figured, and its operculum said to have few whorls.
In the second ] aper, Prof. "VYrrill records Aplysia dactylontela, A. Willcoxi (?) and A. meyctptertt n. sp. The latter is a fine species a foot long. Pleurobranchopsis is a new genus for P. aurantiaca n. sp., a form with no shell, mantle-edge free throughout, gill sessile ; the radula and jaws are not described. C species of DorididtE are described.
TRANSACTIONS OF THE WAGNER FREE INSTITUTE OF SCIENCE, III, Contributions to the Tertiary Fauna of Florida. — "\Ve have more than once in these pages alluded to the importance of this publication to the general student of recent mollusks, no less than to the paleon- tologist. The production of such a work is evidence of an enlight- ened appreciation of the value of these investigations, on the part of the Trustees of the Wagner Institute, no less than a high ideal of scientific work on the part of the author, Professor Wm. H. Dall. The esteem in which the Transactions are held by foreign students is shown by a recent letter from the Australian conchologist, Charles Hedley, an extract from which we venture to print:
" I am most gratified at receiving the volume on the Tertiary Mol- lusca of Florida, but in thanking you for the copy I must also thank you for the labor you have placed at the disposal of every student. I cannot sufficiently express what a boon to me is the generic revision of the various groups. After struggling with the scanty and perplex- ing literature of bivalve hinge structure, I can greet your work as a ship-wrecked mariner might greet the shore. For instance, I have had a quiet little fight with Mysella and have drawn the hinges ready for publication. But I had laid aside the notes and sketches till I could better comprehend the matter. My unsuccessful struggles at least enabled me to appreciate the cost of labor and talent in produc- ing the synonymy of Rocliefortiii. Those who have daily intercourse with fellow workers, who can consult great museums and splendid libraries, will thank you in their turn. But as a scientific exile, without these advantages, allow me to tell you how your Mollusca

of Florida smooths my path, so that I may do with accuracy and speed what I formerly did slowly and painfully."
Apology is due to Mr. Hedley for this unauthori/ed use of a pri- vate letter, and also to Professor Dall. — EDS.
CORRESPONDENCE.
EDITORS NAUTILUS : In the remarks of our friend Hemphill, on pp. 139-140 of the April number, some of us are called to order for a phraseology which is not altogether agreeable to him and other workers on the Pacific coast, and may properly be modified in the interest of their feelings. I refer to expressions which refer to the habitual nomenclature of some shell under discussion, in the cabinets of collectors on the Pacific shores, as in error. I suppose I have been one of those whom he criticises; for being familiar with most of the West coast collections, lists and nomenclature, it has often seemed useful to refer to the name in common use on the other side of the continent, when in the course of monographic revision it has been found to be untenable.
But I should like to assure Mr. Hemphill and all others who have been displeased by such expressions that nothing was farther from my mind than to reflect on the care or desire for accuracy of West Coast workers. I have been of and among them so many years that I feel entitled to claim a place in their ranks, and a large part of the work I have done has been intended to assist them to the extent of my ability. No one is infallible, at least outside of the Vatican. No one can correct the errors of a nomenclature at one fell swoop, so to speak. I have named many thousands of shells for West Coast cor- respondents, and I have named many of them wrong. That is, I have given names which were at the time in current use, but which subse- quent researches have shown to be untenable. If Methuselah was a conchologist, he probably did better toward the end of his career, and the heirs of his original correspondents profited thereby. But alas ! these are degenerate days, and in forty years or so one does not ferret out all anterior mistakes. Therefore if one's gratuitous service does not prove infallible, and one's expressions not invariably happy, let our West coast friends hold fast to the theory of friendly intent, and believe we at the East mean to do our best by them every time. — WM. H. BALL.
