PREFACE.

Ves EU vey

Tue Indian Molluscan Fauna has for a great.number of years attracted the attention of many collectors and zoologists, foremost among whom may be mentioned the following : Benson, Pfeiffer, Stoliczka, Nevill, Theobald, Hanley, the two Blanford brothers, Beddome—unfortunately none of these any longer with us—and Lt.-Col. Godwin- Austen. The Jast named has an intimate and extensive knowledge of the Indian Mollusca, both conchological and anatomical, equalled by no man living. Of the total number of 572 species of land operculates known from India, Ceylon, and Burma, no fewer than 170 have been named and described by him, the next highest number —85—standing to the credit of Benson, while W. H. Blanford is responsible for 64, Pfeiffer following with 42, and Beddome with 25. In the largest genus—Alyceus, containing 145 known Indian species—(Godwin-Austen is credited with as many as 102.

The classification adopted in the present volume is mainly that proposed by Kobelt in Das ‘ierreich,” Lief. 16.

In the marine operculates breathing is effected by means of one or two branchiz. The terrestrial forms, however, having adopted an aérial mode of life and consequently breathing air instead of water, their respiration is carried on, as in the Pulmonata, by a lung formed from the mantle- cavity. In some genera, where the shell is completely closed by the operculum, a tube has been developed on the last whorl, near the aperture, for the purpose of admitting air intothe shell. Suchare: Alycwus, Pterocyclus, Opisthoporus,

Spiraculum, and Rhiostoma, In the last genus the anterior a2

iv

part of the last whorl has become detached, and the tube, which is quite free, is directed towards the penultimate whorl.

As regards the circulatory system, the Indian land operculates are provided with only one auricle, and the pulmonary veins, as well as the auricle—into which they open,—are situated in front of the ventricle.

In their nervous system these families, like other Strepto- neura, are characterized by the loop formed by the two visceral nerve cords being twisted over itself in the form of the figure 0. They also differ widely from the Pulmonata in their digestive and other organs.

In the preparation of this volume the writer has had the advantage of the co-operation of Mr. Hugh Watson, who has kindly read through all the proofs, in the course of which he has made many valuable suggestions. To Mr. G.C. Robson, as on a former occasion, I am indebted for giving me free access to the general collection in the British Museum at South Kensington. Mr. G. C. Leman also has obligingly placed several specimens from the late Col. Beddome’s collection—now in his possession—at my disposal, while to Dr. F. Haas, of the Senckenbergisches Museum, Frankfurt a/M., 1am under obligation for procuring me photographs of the types of two species in the Méllendorff Collection.

This Leptopoma may be distinguished from any of the varieties of L, vitrewm by its angular periphery, dark apex, more convex whorls, deeper suture, double peristome and parietal callus, as well as by the reflexion of the columellar lip over the perforation, and of the narrow lip above it. It is deficient also in the angular projection observable on the lower part of the same lip in that species.” (Benson.)

Hab. Andaman Islands (de Roepstorf); Port Blair (Godwin- Austen).

In “adition to the type Nevill indicates, 7.c. p. 281, var. nicobarica, Martens,” but he gives no description, and I have been unable to trace the name in any of von Martens’ articles. :

Presumably this form is from the Nicobar group, but Nevill does not state this. Kobelt in ‘Das Tierreich’ indicates the Nicobars for the species, probably on the strength of the name.

6 OYOLOPHORIDZ.

Godwin-Austen (1. c.) states that he found in Nevill’s MS. copy ef the ‘Hand List’ the varieties gigantea and «albida—no description of either is given —the former from Port Blair and the latter from the same locality as well as from the ‘“ Brothers.”

The species is now illustrated for the first time from a specimen in the British Museum.

Hab. Burma: Akoutong, Pegu (Blanford) ; Thyat Myo (Hunger- ford).

“This form is allied to Cyclophorus scissimargo, Bens., and C. tomotrema, Bens...... The present species is smaller and higher in the spire than either of the others. The animal of C. leporinus is short, dark in colour, with small black tentacles, and resembles ordinary Cyclophori in most characters. The only specimen obtained living and examined, posssesed, however, the peculiarity of a groove down the middle of the caudal portion of the foot above.

“The peristome is simple in the only perfect adult specimen which I possess, but in a broken barely adult shell, there is a tudimentary duplication. The two lips are probably united in the full grown shell.” (Blanford.)

“This appears to be a representative of the Cingalese group, comprising Cyclophorus halophilus, Bens., C. orophilus, Bens., C. flammeus, Pfr., &. It differs from all except C. orophilus and C. conulus in being spirally lirate, and from these two in several characters of spire, aperture, epidermis, &c.

‘Some specimens of the same or of a closely allied species were found by one of us in Neddiwuttom Ghat on the Nilgiris. They were, however, much smaller, the largest specimen procured only measuring in its two diameters, 44 and 4 mm., axis 44.

Original description :—‘ Shell umbilicated, turbinate, furnished with a thick dark epidermis, which is soon obsolete on the fourth or fifth upper whorl, but always present on the lowest one, where it forms an oblique, coarse, hair-like striation most prominent round the periphery and at the suture of the two lower whorls, and generally round the umbilicus, where it forms quite a fringe ; colour below the epidermis dull olive; spire conical, apex subacute ; whorls 6, the five upper ones smooth, convex, or sometimes the fifth (or fourth and fifth) with a slight rib round the centre ; lowest whorl with two prominent raised ribs round the periphery, with a broad flat apace between them, below convex, smooth or with several raised striz, the whorl descending slightly near the mouth ; aperture oblique, subcircular, slightly angled at the termination of the ribs at the peristome; umbilicus more or less striated within ; peristome single, thin, continuous, or slightly interrupted on the penultimate ; operculum of a single layer, thin,

Hab. India: South Canara range of Ghats, 2500 feet: elevation (Beddome) ; Wynaad? (Beddome).

Fig. 6.—Craspedotropis bilirata. (x 3.)

“This shell is closely allied to Cyclophorus cuspidatus, Bens. (Craspedotropis, Blanf.); it has exactly the same operculum (the two not being in any way distinguishable), which, however, seems scarcely to differ from that of many typical species of Cyclophorus, except, perhaps, in being more closely wound, certainly not enough to constitute a subgenus.” (Beddome.)

Nevill mentions* another Cyclophorus biliratus, Beddome, under the subgenus Leptopomoides trom the Wynaad, but it is uncertain whether this is the same as the Canara form.

The specimen figured is from the Beddome collection, and measures 3°5 mm. in diameter, alt. 4 mm. In describing the species Col. Beddome stated it was allied to Cyclophorus cuspi- datus. Nevill referred it to Craspedotropis, but Kobelt and Méllendorff placed it in Ditropts. Its affinities appear to me to warrant its inclusion in the former rather than in the latter genus.

“Testa translucens, subvitrea, epidermide olivacea nitida instructa, carinis duabus, vel pluribus, una ad peripheriam, altera subtus ab illa interspatio discreta circumdata. Operculum cor- neum, arctispirum, duplex, laminaeinterna membranacea, externa crassiuscula, marginibus anfractuum liberis, ambabus sulco mar- ginali disjunctis. Animal ignotum.

“Shell translucent, almost vitreous, covered with a smooth olivaceous epidermis, with two or more spiral ribs, one of which is always at the periphery of the last whorl, and a second below, separated by an interval from the other. Operculum horny, closely wound, composed of two lamina, separated by a marginal groove, the inner membranaceous, the outer rather thick, and with the edges of the whorls free. Animal unknown.” (Blanford.) :

The lingual ribbon of one species was examined by Blauford.

It differs from that of Cyclophorus in the form of the lateral teeth, and in their denticulations being shorter and more numerous. In C. (Ditropis) convewus, the species examined, the central tooth has 7 denticulations, that in the middle being the largest ; all the lateral teeth apparently had 5 denticulations, but it appeared very difficult to count those in the outermost laterals correctly.

“Shell very widely umbilicated, depressed, discoidal, thin, olive-coloured, very closely and minutely striated, less polished than the other species, and covered with spiral ribbing. ‘Lhe spire is flat, or nearly so, but the innermost whorls being deficient in the only specimen sent for description by Major Beddome, it is im- possible to say whether the apex is slightly exserted or not. The suture is much impressed, Whorls about + in number, convex ; the last one descending near the mouth, smooth near the suture, both above and below, with 7 spiral ribs; 4 above, the outermost forming the periphery of the shell, and 3 below, separated frum the others by a smooth space; 3 of the upper and 1 of the lower can be traced on the penultimate whorl near the suture, but become obsolete on the inner whorls. The umbilicus exposes all the whorls below. Aperture diagonal, round, peristome only joined for a very short distance to the penultimate whorl, thickened, all in one plave and not expanded, faintly edged with white inside, blackish externally.

“The operculum differs from that of Cyclophorus planorbis by the edges of the whorls being less produced externally, and by its

“Shell opeuly umbilicated, depressly convex, thin, smooth, shining, glassy, of an olive colour, with minute sub-obsolete decussating strie, only visible beneath a powerful lens. Spire convex, apex obtuse, suture impressed and with an internal margination, due to the prolongation of the inner whorls of the keel surrounding the shell. Whorls 4, convex; the last descending slightly near the aperture, and becoming paler in colour in front on the outer half of the surface only, so that a band of darker colour surrounds the shell close to the suture. Of the two keels one is at the periphery, and rather lower in position than usual, owing partly to the raised spire, the other is at the base, rather towards the umbilicus, which exhibits all the whorls, and is closely spirally ribbed inside. Aperture round, oblique, peristome in one plane, simple, thickened. Operculum very similar to that of Cyclophorus planorbis, with the external edges of the whorls lengtheued, ragged and split up into a fringe-like edge.

“The flattened depressed form of this shell, and the angular expansion of the outer peristome at the top of the aperture, render it easy of recognition among the depressed and widely umbilicate forms of Cyclophorus.” (Benson.)

Blanford * thinks that some mistake must have been made in Jabelling, for he found the shell abounding in Moulmein, but although he repeatedly searched all round the Akoutong Hills he

never met with it. He also states * that Benson’s description “must have been taken from a dead specimen which had lost both its epidermis and operculum.” In living specimens he found the shell covered with “a scabrous dark epidermis, radiately striated, and with raised spiral lines which, as in C. hispidulus, were more marked in young than in adult individuals. The operculum was slightly concave externally, in consequence of the edges of the whorls being raised and ragged, especially near the circumference; internally it was smooth and nearly flat, with a small central nucleus. C. calyw is well distinguished from C. hispidulis and C. pinnulifer by its smaller whorls, the strong subangulation around the umbilicus, the ornamentation beneath the epidermis and the markings of the epidermis itself, the raised ridges surrounding the. shell being fewer and much more pronounced in C. hispidulis.”

Stoliczka found the animal ‘identical in form with those of other Cyclophoride, only of smaller size; when full grown the body is black, with very long subulate tentacles, slightly thickened near the tips, the rostrum is long and deeply cleft in front, the foot rather elongated, posteriorly narrowly produced and pointed ; eyes rather small, placed laterally at the base of the tentacles on barely perceptible bulgings. The sides of the foot and the tentacles are usually paler than the body, and young specimens are pale erey coloured throughout. The largest specimens found south of Moulmein measure: Diam. maj. 14; d. min. 12; alt. teste 7-2, alt. ult. anfr. cum perist. 5, diam. apert. int. 4 min.”

“The operculum is more closely wound than in C. parma, from which it differs in colour, the form and position of the aperture, sculpture, and deeper umbilicus; this part is shallower than in its near ally, C. annulatus, Trosch., which exhibits, moreover, a prominent dark apex to the spire, whereas in C\ cratera the apex 1s flattened and white. The variation in size is considerable, as may be seen by reference to the measurements. The smallest variety exhibits the adult character: the narrow volutions of the operculum, and a darker corneous hue than in C. parma, are constant. Its double peristome and the flatness of the apex at ouce distinguish it from C. Thwartesi, Pfr.” (Benson.)

The author considers the keeled edges of the whorls of the somewhat thickened operculum to form a striking character in this species, affording indications of un approach to the operculum of Pterocyclus. C. loxostoma, Pfr., and C. bairdi, Pfr., are allied, but from the latter it differs in the flat spire, the formation of the aperture, the colouring, and the absence of spiral striation.

Weis Sita 4 The shell is easily distinguished from the other planorbular Cyclophori of Ceylon by its dark colour and depressed form, which recall those of Pterocyclos hispidus, Pearson, by its very wide and shallow umbilicus, and by the size and peculiar position of the aperture. The whorls of the operculum, which is of a clear horn-colour, are less closely wound than in C. cratera.” ( Benson.)

Although the larger of my two specimens does not bear the signs of age, yet, even if the peristome should be found to acquire a further development, the peculiar dull and sharp scabrous sculpture, as well as the narrower umbilicus, will serve to prevent

“The species differs from C. annulatum, Troschel, which has a similar operculum, in the more closely-wound whorls, in the narrower umbilicus, more delicate sculpture, and absence of any pattern on the upper side.” (Bensou.)

Blanford states ¢ that the species attains a considerably larger size in the Anamullay Hills and the Wynaad than the type, shells from the former locality measuring 27 mm. by 22 mm., and

from the latter 24 mm. by 19°5 mm. The operculum, when in good condition, has raised margins to the whorls. He was in-

clined, however, to consider the species identical with C. annulatus, from Ceylon.

Nevill separated these two forms from the type as varieties, naming them anamullayensis and wynaadensis respectively, with- out, however, giving any definition; he even added in brackets “@ sp. nov.”

The specimen now figured is from the Beddome collection kindly lent by Mr. Leman. It measures 16 x 14mm. in diameter, alt. 8 mm. The operculum is many-whorled and closely coiled. 62. Theobaldius shiplayi, Pfeiffer.

52 CYCLOPHORIDZ.

“The young of C. nilagiricum preserved its distinctness from C. Jerdont in the same condition by its sculpture, colour, the depression of the spire, the broad flattening observable above the shoulder of the whorl, the angulation of the shoulder, the excavation of the periomphalum, its compressed angulated edge, and by the blue colour of the interior, which is bordered with chestnut in the young, but gradually gives place to the orange of the peristome in the adult example of C. nilagiricum, while the whole of the interior is white in both states of C. Jerdoni. The spiral strie are not very conspicuous on the underside of C. nilagiricum, and are entirely discontinued at a short distance from the periphery, the region of the umbilicus being smooth. In most of the allied species the umbilicus and its neighbourhood are pale, but in this species the dark chestnut ground colour of the shell extends over the whole exterior surface where not broken by flecks or streaks of whitish.” (Benson.)

“With a general resemblance in form to CO. indicus, Desh., it will be at once distinguished by the absence of a keel or acute spiral ribs, by the wider umbilicus, less developed peristome, and more elevated form. The very gradual arcuation of the columellar lip is also an essential character, detracting from the uniformity of the circular aperture. The sinus observable at this part, impinging on the plane of the aperture, is also conspicuous in C. indicus.

“A variety oceurs in which the shell is of a pale buff colour, darker towards the apex, the bands and markings being obsolete, and the colour of the peristome being equally vivid with that of the typical shells. Another thinner variety occurs in which the interior coloured lip is not present.” (Benson.)

“Tt differs from this species [Cyclophorus indicus] in its more elevated form, indistinct keel, rounded last whorl, more elongate aperture, porrect inner lip, the absence of any sinuosity in the plane of the aperture on the columellar lip, less expanded outer peristome, and by the greater expansion of the external columellar lip over the umbilicus, which is also much narrower; and permits no view of the internal whorls.” ( Benson.)

Nevill regarded the present species as a variety of C. hima- layanum, Pfr., but Benson, while admitting near relationship, considered the two forms distinct. The latter is more depressed and has a wider umbilicus. Pfeiffer, on the other hand, classed it as a variety under C. stenomphalus, but the figure in Conch. Icon., which illustrates one of Benson’s specimens, does not bear out this view.

“This shell differs from the pale-lipped C. pyrotrema, in which the aperture is not fully developed, by its more globose form, ventricose last whorl, small impervious umbilicus, more regular sculpture above, stronger sculpture below, thinness, pale colour, and the absence of any medial fascia. From the pale-lipped variety of C. stenomphalum with undeveloped peristome, it differs by the greater breadth of the aperture in proportion to its length, its non-pervious umbilicus, the absence of any carina at the periphery, the more closely suleate and regular sculpture above, the extension of the sculpture on the under side into the umbilicus, its pale suite of colours, and by the absence of any colouring below the periphery. From C. indicus it may be known by the absence of keel, suite of colours, sculpture, and aperture.” (Benson.)

Nevill doubted its validity as a species, for in his Hand List, while admitting the name, he adds in parenthesis “? small var. of C. himalayanus.” Tt may be that the shells collected by Stoliczka in Sikkim differ somewhat from the type. Another set of eight shells, collected also by Stoliczka at Kurseong, near Darjeeling, are separated by Nevill as a variety which, however, he does not name, but he adds in parenthesis ‘‘? C. polynema, Benson.”

“This is a very distinct form allied to C. bensoni from the southern face of the Khasi Hills, shewing towards the apex in some specimens a tendency to the zigzag painting of that shell, but the uniform, striate, and sober colouring of the rest of the whorls is a very marked character. Two specimens have a moderately broad white band on the periphery, owing to the abrasion of the epidermis upon the raised ridge of the keel.” (Godwin-Austen.)

‘La coloration est peu variable; sur un fond d’un fauve pile se montrent des marbrures, et souvent des flammules longi- tudinales, d’un brun plus ou moins foncé, suivant les individus. A la circonference, ot il existe une caréne peu saillante, se montre une zone transverse d’un brun noirdtre, au dessous de laquelle on en voit deux ou trois autres beaucoup plus étroites qui entourent l’ombilic.

“This species is remarkable for its flat, disk-shaped expanded peristome, usually of a bright orange or scarlet colour, and for the absence of marked sculpture, and, in most specimens, of any conspicuous coloration, except a single broad dark chestnut stripe below the periphery.” (Blanford.)

Hab. Burma: Thayet Myo, Prome, and Henzada, Prov. Pegu (Blanford).

Blanford refers to the fact that Theobald classes C. patens as a variety of C. fulguratus, but does not agree with this view. He states that both oecur together at Thayet Myo and are very distinct, C. patens having a broad, rather thin disk-like expanded peristome, while the lip of C. fulguratus is much thicker but only moderately expanded. The former also is much smoother.

Hab. India: Khasi Hills, Assam (Pearson); Dafia Hills, Assam (Godwin- Austen); Tezpur (Stoliczka); Sylhet and Gaubati (Nevill) ; Lacat (Theobald).

‘In form, sculpture, and markings C. Pearsont much resembles, in the back view, the shell figured by Sowerby, no. 128, pl. 27, of the ‘Thesaurus’ as C. perdix, but the spire 1s less acute. It differs otherwise in the narrower umbilicus, in the orange colour and rounded edge of the peristome (which is destitute of the flatness observable in C. perdix), as well as in the amplitude of the aperture, convexity and want of keel in the whorls, and in the absence of the articulated band at the suture.” (Benson.)

Nevill mentions a var. minor, from the Khasi Hills, as being smaller, with less open umbilicus, and more angulate periphery. He also refers to a peculiar small variety from Sylhet, which he does not name, with a much raised spire, the last whorl almost detached, and the periphery acutely keeled. This, however, can scarcely be considered a variety, and must rather be regarded as a monstrosity.

Prevailing colour above is dusky brown, clouded by yellowish spots of various sizes, which on the posterior whorls, are arranged in radiating zigzag series ; a broad space around the umbilicus, which is very large and deep, is light straw color, with occasional revolving black lines or bands ; apertureample, somewhat wider than high, bluish within; peristome moderately reflected, rounded, of a beautiful carmine, or bright cherry-red color, not continuous, but embracing less than one fourth the preceding whorl, across which space passes a callus of the same red colour. Diameter 2 inches, height 1 inch.” (Gould.)

Distinguished from Pt. rupestris by the length and narrowness of the alar prominence, which ascends slightly on the penultimate whorl, and runs parallel with it, instead of spreading semi- circularly as in that shell. From P¢. albersi it differs not only in size, but in the absence of the incurvated beak which is such a prominent feature in that species. The umbilicus, equally broad with that of Pt. rupestris, is somewhat deeper in proportion.” (Benson.)

Original description :—“ This is a form that has hitherto been confused with Pt. nanus, Benson, the shell is more depressed and of thicker substance, resembling more closely Cyclophorus stenostoma, Sowerby, both in form and colouration; it can be distinguished at a glance by the apparently constant absence of the conspicuous band at the periphery ; I intended, despite all the above, to have merely separated it as a subspecies, when I noticed that all my Anamullay specimens have a much raised, concave operculum,

Original description:—* This shell is similar in form to P. parvus, only that the winged portion of the peristome is far more fully developed and folded round into a perfect, largely developed tube with its internal orifice just within the aperture, the inner lip being deeply notched to give room for it. The shell is ornamented with a single black peripheral band and with minute transverse brown zig-zag markings. Apex very flat. Whorls 5, rounded.

“The largest example measures—alt. 0:26 [6 mm.], major diam. 0°95 [24 mm.], minor diam. 0:75 [19 mm.], apertural tube 0°20 inch [5 mm.]}.” (Godwin-Austen.)

Hab. India: Dafla Hills, Naga Hills, Assam (Godwin-Austen).

The following additional details are given by Nevill, who con- sidered it doubtfully more than a well-defined variety of P. parvus. The compressed last whorl, which is semi-detached at the pro- portionately smaller aperture, the more open umbilicus and the different character of the “tube” distinguish this form from the large variety of P. parvus.

‘Possessing a similar deep umbilicus, narrower than in the other known species, it was overlooked as a young and imperfect specimen. On examination it proves to have arrived at its full growth, being allied in the characters of the aperture to Pt. rupestris, nobis, but differing from the smallest varieties of that shell not only in size and in the form of the umbilicus, but also in the less curvature of the incision under the wing, which is moreover less expanded, and does not touch nor cover any part of the preceding whorl.

“Shell openly umbilicated, depressedly orbiculate, somewhat globose. Sculpture, only fine epidermal lines of growth. Colour dark sienna-brown, crossed by dark bands, running from the suture to the narrow black periphery band. Spire slightly raised, very depressedly conoid. Suture deep. Whorls 4, the last rapidly increasing. Aperture circular, subvertical. Peristome slightly reflected, not much thickened, the outer lip is expanded near the suture, with sides turned in forming a spout-like projection. Close behind this and adjacent to the suture is an apparent tube, but it is rather of gutter form, semicircular in section, and is given off from a cleft on the columellar side just within the aper- ture, which is not an orifice—if it were so the gutter would be a true tube and the shell a Spiraculum. It illustrates how the sutural tube in that genus has originated. This species is on the borderland of the two genera Pterocyclos and Spiraculum. It must be put in Pterocyclos, because the tube is close to the aperture, almost a part of the peristome. In Spiraculum the tube is remote from the aperture. Operculum concave in centre, multi- spiral, suture not raised.

“Tn most respects this species is very like nagaense, Aust. & Bedd., but can be easily separated by the position of the breathing tube, which in assamense is much nearer the aperture. The operculum of nagaense does not appear to have so many whorls as our species, a large part of the central portion being quite flat and smooth.

“Lt. G. F. T. Oakes, R.E., has sent me seven examples of this species from Sibbum, far finer in size; four are bleached. The largest measures 10 mm. in major diameter. Three are perfect with strong epidermis. Colour sienna-brown in tint with ochra- ceous mottling, with an indistinct peripheral band. Major diam. 11:5 mm.

“This is a close ally of Spiraculum kempi, but the closely mottled zig-zag pattern and black peripheral band is not seen in that species ; in this respect it is similar to Spiraculum neville of the Dafla Hills; it is smaller and rather flatter than that shell.

“Tt is hardly possible to find better examples showing the deve- lopment of the sutural tube in Spiraculum than in the species figured on plate xl. Although it is not from the ‘I'sanspu Valley but from the source of the Irrawady, Spiraculum putacensis has been introduced in order to show how close is the relationship and how beautiful evolutionary stages have been. In having a tube on the suture behind the peristome and a simple peristome, both belong to the genus Spiraculum. In figures and 3 6, within the aperture may be seen the little orifice having a connection with the branchial sac. In Spiraculum minimum this is very close to the aperture, in Spiraculum putaoensis it is more remote. In the first the inner and outer lips of the peristome are united and thickened at the upper inner margin next the suture, while in the second there is further development; a clear separation of the lips has taken place, the inner has a slight nick on the line of the suture, shown by a sort of cicatrice up to the branchial orifice, and the outer lip is expanded forward into a short scoop- like process corresponding to the wing, as it has been called, of Ptervcyclos. The next species (fig. 4) [P. spiramentum] might

be placed in this genus and is a true link with it. The tube is so far forward, it still forms a part of the peristome, a complete isolated orifice has not yet been formed—it is a slit; the process of its further development would be the growing more forward of the whorl itself. In fig. 5, Spiraculum lwyorensis, we find this stage reached, and in fig. 5 6 the internal orifice has been left behind, and externally a perfect tube is seen on the suture (lig. 5 a) behind the aperture and completely separate from it. While this evolution has been in progress, another change has taken place; the scoop in fig. 4 has grown forward considerably into the elongated gutter of fig. 5, with its edges growing inwards and nearly touching, corresponding in life, in all probability, with a sharp fold of the mantle edge, which with further growth might become more and more tube-like.” (Godwin-Austen.)

Original description :—“ Shell discoidal, convexly depressed, widely umbilicated, covered with a dark brown epidermis which soon becomes eroded, and with an incipient dark band on the keel in perfect specimens. Spire very slightly raised, suture deep, whorls 5, much rounded, the last descending slightly towards the aperture. The sutural tube is only 0°10” [2:5 mm.] in length, 0:3” [7-5 mm.] behind the aperture, turns back, and is situated close to the suture. Aperture oblique, circular. Peristome double, inner lip continuous, baving at the suture a re- entering angular notch, the outer is similarly notched and then expanded and folded into a spout-shaped form. Operculum not seen, probably as in S. hispidum.

Alt. 0°36 [9 mm.], major diam. 1:05 [26°5 mm.], minor diam. 0°92 [23°5 mm.], apert, 0°45 in, [11:5 mm. ].”

Hab. India: Dibiri Parbat, Dafla Hills, Assam (Godwin-Austen).

“This Spiraculum is quite distinct from S. hispidum, for which I mistook it when found, and consequently omitted to search for more examples. In the form of the sutural tube it most nearly resembles S. avanum W. Blt., thus differing very considerably from S. hispidum, in which that part is broad and curves quite over and across the suture in well-grown shells. The most not- able point of difference, however, is the expansion of the outer lip into a tube-like process, in which respect the species shews its very close aflinity to the genus Péerocyclos.” (Godwin-Austen.)

Original description :—‘ Shell broadly umbilicate, depressedly turbinate, and, in the single aged specimen found, decorticated, whitish and smooth throughout. Traces of a brown epidermis remain around the umbilicus, and younger specimens are probably brown in colour, and perhaps ornamented with coloured bands, like other species of the genus. Spire raised, depressedly conical, suture deep, apex acute. Whorls 43 rounded ; the last cylindrical, descending, and free near the aperture, and provided above, about three millimetres behind the mouth, with a rather elongate tube, which projects forward, and is in contact with the penultimate whorl throughout. The tube appears broken at the end, and may have been even longer originally ; the anterior termination in the specimen is in a line with the oblique peristome of the shell. Aperture diagonal, circular ; peristome double, inner lip sharp, not projecting much, curved backwards near the penultimate whorl ; outer peristome expanded, and wavy above externally and below, straight and somewhat narrower on the left margin. Operculum nearly flat externally, concave within; the outer margins of the whorls free and lamellar, except towards the middle; the circum- ference surrounded by several raised lines, the edges of the outer- most whorls. Major diameter 123 mm., minor 104, axis 7, diameter of the mouth 54 mill.” (Blanford.)

Original description :—“ Shell broadly umbilicated, depressed, nearly discoidal, greyish white with irregular streaks and spots of chestnut and two bands of the same colour; one, somewhat interrupted, below the periphery, the other broader, within the umbilicus. Spire almost flat, the apex prominent and papillar, the suture deeply impressed. Whorls 5, rounded, the last cylin- drical, gradually descending in front and furnished, 4 mill. behind the aperture, with a short, nearly vertical spiracle, in the form of a truncated cone, and joined to the penultimate whorl. Aper- ture diagonal, circular, the peristome double, the internal portion projecting slightly and obtuse, with a rather shallow angular sinus near the suture: the external peristome is continuous, expanded, dilated above into a projecting wing which runs forwards for some distance along the last whorl in front of the aperture, and is bent downwards at the end. Near the base of the columellar margin there is a small gutter-shaped projection. The operculum is very concave within, externally convex, flattened at the apex, with free lamellar edges to the whorls as in the typical species of Pterocyclos.

Original description :—“ Shell umbilicated, ovate, spirally lirate, furnished with a light-bright brownish, obliquely striated, thread- like epidermis, and a few hairs along the spiral costulations, white beneath the epidermis ; spire conical, apex subacute ; whorls 5, the lowest with about eleven spiral costulations continuous down to the umbilicus, the four upper lines nearest the suture less con- spicuous, or subobsolete ; the penultimate with three to four spiral lines, umbilicus moderately open, spirally lirate within ; aperture oblique, oblong, the vertical and spiral lines clearly visible on the inside of the whorl; peristome continuous, or a little interrupted at the apex on the penultimate whorl, double, except on its inner or left margin; the outer lip expanded and reflexed on its outer margin, contracted at its base and again prominently expanded at the base of the columellar margin, the inner one white, shining, and minutely crenulated on its outer and lower margins ; oper- culum as in C. wynadense, with a moderate transparent nucleus : length } inch (2°5 mm.], greatest breadth ;'; inch [2 mm.].”

Hab. \ndia: Yellagherry Hills, Salem District.

“The epidermis and spiral costulations are very similar to those of jfilocinctum and wynadense; it is, however, a smaller species, and ovate, not turbinate in form, and with a different

operculum. C. filocinctum has the inner lip of the peristome furnished with large, prominent, obtuse, white crenations; and the spiral ribs or costulations on the base of the lowest whorl are always continuous up to the umbilical region, there being no in- tervening smooth space. C. wynadense has the inner lip of the peristome smovth ; and the spiral costulations on the lower whorl are generally interrupted by a smooth space before the umbilical region is entered; but this latter character is not constant, as some of my specimens have the costulations continuous up to the umbilical region, as in filocinctum, so that it cannot, in the absence of the operculum, be looked to as a characteristic to distinguish them; but the peristome, where the shell is adult, is a safe character.’ (Beddome.)

CYATHOPOMA. 141

A larger form than the type is recorded by Mr. Sykes * found by Mr, Collett at Lower Ambagamuwa (2500 ft. alt.). It differs trom the type not only in its greater size, having an additional whorl, but also in its more elevated form, and in the more strongly marked spiral sculpture, the lire also being more numerous; the periostracum, moreover, is thicker, and, under a Jens, gives an obsoletely decussated appearance to the shell.

Hab. India: Shevaroys and Yellaghirry Hills, Salem District (Beddome).

“This species comes nearest to C. kalryenense, but wants the crenated aperture and is considered distinct by Mr. Blanford.” (Beddome.)

Nevill, when figuring this species,t gave some further parti- culars of the operculum, which he states ‘externally presents a curious analogy to that of some species of Zurbo; it is convex, testaceous, smooth, with only a very small and inconspicuous ‘umbo,’ or opening, which is situated considerably above the centre, consequently near the top of the aperture.”

“Nearly allied to Cyclotus filocinctus, Benson, by the peculiarity of its operculum, this shell is distinguished by its smaller size, more depressed form, and less expanded peristome, by the absence of the marked sculpture of C. filocinctus, and by the epidermis being lighter in colour and marked by brown transverse streaks on the last whorl. That of C. filocinctus is hispid.... The construction of the operculum is very peculiar. The testaceous spiral lamina being very much more raised towards the exterior than towards the centre, and being curved inwards, the interior whorls of the operculum are almost concealed and the appearance, unless very closely examined, is that of the operculum of a Turbo hollowed out at the centre. The lamella in C. malabaricus is rather more elevated than even in C. filocinctas.” (Blanford.)

Cyathopoma (Mychopoma) hirsutum, Nevill, Hand List, i, 1878, p. 260.

Original description :—“ Shell umbilicated, depressly turbinate, rather solid, covered with a thick dark coloured epidermis, which has strong raised decussated sculpture of spiral ridges and very close oblique costulation; at the periphery and around the umbilicus there is a fringe of close, rather long hairs, and the outer series continued on the inner whorls forms a sutural fringe also. Beneath the epidermis the shell is white with decussating lines, the spiral sculpture being more pronounced and the ribbing corresponding to the lines of growth less so than outside the epidermis. Spire convexly conoid, the apex prominent and papillar, suture deep, nearly concealed by the hairy fringe within. Whorls 5-53, convex, the last cylindrical, descending but very little in front. Umbilicus pervious, exhibi- ting all the whorls, spirally ribbed, partly covered by the surrounding hairy fringe. Aperture diagonal, round, rather milky inside, with dark horizontal lines corresponding to the spiral ribs on the shell; the peristome is thick and double, curved backwards near the umbilieus, the internal portion with minute

156 CYCLOPHORID#.

pearly denticulations, largest on the outer (dextral) margin and gradually decreasing slightly in size on the upper and_ basal edges, vanishing entirely near the umbilicus; the external peristome is slightly expanded, the edge cut into minute teeth like those of a saw except on the inner or columellar margin. Operculum externally slightly concave, white, calcareous ; the spiral sculpture obsolete ear the centre in old specimens ; internally membranaceous.

“Major diameter 53, minor 7, axis 54, diameter of the aperture 35 millim.” (Blanford.)

Hab. Sudia: Calead Hills, Travancore (Beddome, Bourdillon) ; Tinnevelly Hills (Beddome).

“This is a very curious and interesting species which, while differing in many respects from any known form, has marked affinities with shells belonging to distinct groups. Had the shell been discovered without the operculum, there could have been very little hesitation in considering ita large form of Cyathopoma ; the sculpture and general shape are precisely those of the types of that genus, and in some species, such as Cyathopoma filocinetum, there is a thick epidermis, and also the very singular internal crenulation of the mouth, which is more marked in the present shell than in any allied species. The operculum, however, is totally different: instead of the whorls having the curious raised and incurved edges so characteristic of Cyathopoma they are flat and almost obsolete near the centre, on the outer surface, being far less distinct than in typical species of Cyclotus.

“The hairy fringe around both the periphery and the umbilicus so closely resembles that in Cyclophorus (Craspedotropis) cuspidatus, Bens., that there can be no question of a certain allinity between the two species, and there is considerable resemblance in their general form. The apertures, however, differ greatly, and there are marked distinctions in the operculum.” (Blanfori.)

In some specimens, as in A/. hirsutwm, there are oblique raised lines outside the epidermis, but they are not always conspicuous. Spire conical, suture deep. Whorls 53, convex, the last cylindrical, scarcely descending towards the aperture which is oblique and nearly circular. The peristome is much curved back, near the umbilicus, where it is almost simple and scarcely expanded: elsewhere the outer portion is sharply reversed, forming a broad rim at right angles to the axis of the whorl on the outer and basal margins, while near the penultimate whorl it is produced in front. The inner portion of the peristome scarcely projects beyond the outer; it is corrugated within, but not nearly so strongly or closely as in Af. hirsutwm, and the corrugation is very faint towards the base, and entirely wanting at the angle of the aperture and on the columellar margin.

Raphaulus assamica, Godwin-Austen, Rec. Ind. Mus, viii, 1917, p. 570, text-tig. 1 a.

Original description :—‘ Shell elongately cylindrical, solid, rather tumid, flattened on the frontal surface of the penultimate whorl ; sculpture regularly closely costulate ; colour dull umber-brown ; suture moderately impressed ; whorls 6, penultimate the largest with sides flat, the next much smaller and convex; aperture perpendicular ; peristome very thick, double, both continuous, but the outer only has a thin callus on the whorl.

“The sutural tube has its origin on ‘the upper outer margin close upon the outer lip, is colourless, and turns sharp downwards behind it, extending to nearly the height of the last whorl. This peristomial tube is not a tube in the strict sense of the term, but in section is semicircular, an arch resting upon the body-whorl, which forms the diameter. An inner sutural tube follows the suture backwards; it opens internally 3 mm. within the aperture, it is indistinctly shown on the exterior, but the lines of costulation extend over it, differing thus from what is seen in the similar tube

238. Rhaphaulus luyorensis, Godwin- Austen.

ie ca luyorensis, Godwin-Austen, Rec. Ind. Mus. viii, 1917, p. 578.

Original description :—* Shell umbilicated, Pupina-like, solid, shining; sculpture fine close shallow striation; colour pale ochraceous ; spire fairly high, apex blunt and rounded; suture impressed ; whorls 6, 4th and 5th the largest and nearly equal in diameter ; aperture circular; peristome thickened, reflected, with a callous on the body-whorl; the sutural tube flattened, follows the suture and is perforated finely at intervals.

Major diameter 4°75, alt. axis 8 mm.”

Hab. India: Luyor Valley (Oakes).

“This a close ally of 2. blanfordi, but can be distinguished at once by its much more tumid form and blunt apex. It is far nearer to the Sikhim shell than the one which has been described as £. miriensis.” (Godwin- Austen.)

RHAPHAULUS. 167

239. Rhaphaulus miriensis, Godiwin-Austen.

ee mirtensis, Godwin-Austen, Rec. Ind. Mus, viii, 1917, p.

Original description:—* Shell cylindrical, pupiform, strongly excavated and keeled on umbilical region; sculpture very fine transverse regular striation; colour bleached; spire high, apex conic; whorls 6, the 4th with the greatest diameter, sides flatly convex, the aperture circular; peristome thickened, not continuous on upper margin.

“Major diameter 5, minor 5, alt. axis 9-4mm.” (Godwin-Austen.)

Hab. India: Miri Hills (Oakes).

The only specimen received was unfortunately crushed before the description was complete. The sutural tube is stated to be exactly like that of Rhaphaulus blanfordi of Sikhim, i.e. “a narrow flat band running back along the suture with ‘here and there minute perforations.” Fortunately the two species had been compared, and the Miri shell was found to be “quite distinct, that the antepenultimate whorl was the largest and the sculpture very much finer; the deep excavation at the umbilicus was another very remarkable character.”

Fig. 26.— Tortudosa albescens,

Differs from T. caleadensis, with which the species has been confused, in having one whorl less, and being much smaller, with proportionately shorter whorls; the sculpture is less close and distinct, the colour whitish instead of golden brown, the basal keel less developed, and its opening is in the same plane as the aperture, instead of being turned downwards. From 7. costulata it is ehiefly distinguished by its much finer sculpture and by the characters of the basal keel.

Original description :—“ Shell subperforate, fusiformly turrited, solid, closely and rather sinuously costulated. Spire ovately turrited, apex rather acute, suture much impressed. Whorls 8, convex, the last a little smaller, quite free from the other whorls for a short distance behind the mouth, but not descending much, not nearly so far as C. tortuosus is represented as doing. The basal keel is strong, compressed, transversely ribbed, and becoming larger in front; the space inside the keel around the umbilicus is of moderate size and ribbed. Aperture nearly circular and almost vertical, the opening of the basal canal being at the left side and not in the same plane as the aperture, but turned a little down- wards and to the right. Peristome thickened, double, the inner portion obtuse, the outer expanded, turned back, produced below the canal and above near the suture, narrower on the inner margin and not touching the penultimate whorl, Operculum unknown,

“Tength 16-21, major diameter (peristome included) 53-7, minor 5-64, width of aperture inside 3-34 mm.

“Length of the aperture and outer peristome in the larger specimen from the base of the canal to the end of the projection above 64 mill.”

Hab. India: Calead Hills, Travancore (Beddome).

At first sight, this shell bears a most striking resemblance to C'’. tortwosus, Chemn., but the last whori is much less produced, and there appear, judging from the description and figures of Chemnitz’s species, to be several slight but not unimportant distinctious in sculpture and form. Amongst the Ceylonese species, the nearest approach to the present is made by C. decorus, Bens., and C. blanfordi, Dohrn, but no Ceylonese kind is known witb the last whorl free. The previously described Cataulus from the base of the Anamullay Hills resembles C. caleadensis in the sinistral position of the keel, a character not noticed by Pfeiffer in his description.” (Blanford.)

In 1880 (doc. cit.) Blanford recorded the receipt of fresh living specimens from Col. Beddome of a golden-brown colour, with the aperture of the same tint as the shell. The peristome in these specimens was not free from the last whorl: the operculum was found to be normal and precisely similar to that of Ceylonese species of the genus.

At the same time Blanford stated that he was satisfied that the specimens described by Theobald as Hapalus travankoricus were immature shells, and he believed them to be the young of C. caleadensis or some nearly allied species.

Cataulus connectens, Fulton, Journ. Malac. x, 1903, p. 102, pl. 9, fig. 4; Sykes, op. cit. xii, 1905, p. 55.

Original description :—“ Shell fusiform, oblong, solid, narrowly perforate, dark reddish-brown; whorls 93, obliquely striated, lower slightly convex, earlier whorls almost straight, the last carinated at the base; aperture circular, pale reddish-brown within; peristome continuous, yellow, thickened and reflexed, an egg-shaped opening to basal canal. Operculum normal.

Major diam. (including peristome) 83, alt. 21 mm.” (Fulton.)

Hab. Ceylon: Watawala ( Collett).

Stated to be closely allied to blanfordi, Dohrn, and decorus, Bens., but readily separable from the former by its yellow peri- stome, from the latter by its smaller size and more slender form, and from both by the peristome being more in line with, or under, the whorls.

Mr. Sykes considers it to be only a local race of blanfordi with yellow peristome.

colour. Spire turreted, with convex sides, apex rather obtuse, sutures well impressed. Whorls 73, convex, the last more closely wound than the penultimate, to which it is scarcely attached just behind the mouth; the basal keel compressed, costulate, dilated in front; the space inside the keel and around the umbilicus is of moderate size and ribbed. Aperture nearly circular and subvertical, with the opening of the basal canal on the left side of the base, and not quite in the same plane as the aperture, but turned rather downwards. Peristome white, thickened, expanded, and turned back, produced above to the right of the penultimate whorl and below around the canal, narrow on the columellar margin, and only united for a short distance with the penultimate whorl.

“Length 0°65 (16 mm.], breadth (including the peristome) 0°25 [6-25 mm. |, minor diameter from front to back 0°28 [5°75 mm.], width of aperture inside 0-13 [3°25 mm.] inch.”

Hab. India: Tinevelly Ghats (Beddome).

“This species of Cataulus, the third hitherto obtained from the hills of Southern India, is distinguished from all other known forms of the genus by its comparatively coarse ribbing across the whorls. In other respects, it closely approaches C. calcadensis, Bedd.,..... having a similarly shaped spire, aperture, and basal channel. I have only seen one specimen of C. costelatus ; this differs from C. caleadensis not only in having stronger sculpture, but also in being rather shorter and in having one whorl less in the spire. he colour of C. costwlatus also is paler than that of the Calcad shell, and the lip of the aperture is white.

Like the other Southern-India forms, C. ealcadensis, C. recur- vutus, and the species hereafter described [C. albescens], C. costu- latus has the canal a little to the left of the lowest portion of the aperture, or nearer to the umbilicus than to the outer margin. In most Ceylonese species of the genus the canal is nearly at the lowest portion of the mouth (it is slightly to the left in C. pyra- midatus, C. ewrytrema, and C. austenianus; basal in the smaller forms, like templemanniand C.layardi). I find that in C. tortuosus the position of the canal is precisely as in C. calcadensis and C. costulatus (in C. recurvatus, the sinistral position of the canal is much more marked).” (Blanford.)

Shell more solid than typical greeni, somewhat broader in form, the oblique striz and crenulations at suture more con- spicuous, the notch on upper right margin of peristome varies from being almost entirely absent, to specimens having a small but clearly defined V-shaped one.

With reference to the distinct notch supposed to be charac- teristic of greent, I have before me a specimen of the typical form from Punduloya, which scarcely shows the notch, thus demon- strating the instability of that character.

As compared with C. aureus the present shell is straw-yellow and not golden yellow in colour; itis much Jarger with flatter whorls, the mouth is subcircular and lacks the angle at the upper right hand margin, etc. From C. austenianus the shape aud colour of the moutb and lip, as also the elongate form, will suffice to sever it; similar variations distinguish it from the white-lipped var. of C. heemastoma. 1 would lay stress on the second carina at the base.” (Sykes.)

“In the obsolete channel, occasionally visible at the top of the aperture, this shell has possibly some relation to Gould’s Al, sectilabre. The indentation, invariably present in the internal callus of the aperture, seems to hive some reference to the obliterated channel, and shows a passage to the Pupinr. The form has a great resemblance to that of the gigantic P. grandis, Forbes (forbest, Pfr.), which it exceeds in size. As in that shell, the great length of the penultimate whorl, above the aperture, contrasts with the shortness of the same part in the allied species M. chrysallis, Pfr.” (Benson.)

“This interesting species inhabits the same locality as A. constrictus, described in the tenth volume of the Annals,’ but differs in form and sculpture and in the position of the sutural callus. The strangulation is less conspicuous than in other species of Alycceus, and the constriction occurs immediately behind the peristome; hence the sutural callus also commences. near the aperture instead of being remote as in the other species. A brown murk, in the single specimen which has come to hand, occurs at the point where the callus is given off. The callus lying in the suture is also longer than in the orbiculate A. strangulatas, in which it is moderate, or in A. constrictus, where it is short. The number of whorls in the operculum of A. strangulatus is much greater, and they are more compactly wound than in either A. urnula ov constrictus ; in A. urnula the sutures are tolerably distinct, and the central whorls are slightly concave; in A. con- strictus the sutures are inconspicuous, as originally noted.” (Benson.)

The shortness of the constriction, and the very slight degree in which itexpands towards the aperture, connect this form somewhat with the section Dioryw of Mr. Benson.” (Blanford.)

“Tt isa more globose form than either A. succineus, mibi, or A. polygonoma, mihi, to which it is allied. The crenulation of the mouth is perhaps more marked than in any other Burmese species.” (Blanford.)

“« .,. the costulation at the base of the sutural tube is particularly strong, and at first distant, and I would call attention to the well-marked distant fine costulation on the smooth part of the whorl anterior to this, the four coste behind the peristome are very noticeable. The same species has been collected at Ava; in all the examples I have looked at, the peristome is less crenu- lated and in two or three is hardly noticeable. The ribbing behind the peristome is quite as strongly developed.” (Godwin-Austen.)

In 1893 Godwin-Austen, after comparing this shell with typical A. ingrami, became convinced that it was quite distinct and gave it the specific name of distinctus. Another form, from the Dafla Hills, originally considered to be a variety of ingrami, was like- wise raised to specific rank under the name of macyreqori.

A variety is recorded from Sadia, collected by M. Ogle, on page 363 of the same work and figured on pl. 187, figs. 2, 2a, 20. It is stated to differ from the type in its flatter depressed shape, rounded aperture, and the shorter distance from it to the sutural tube.

Another variety, collected by F. Ede at Naraindhur, Cachar, is described on page 391 and illustrated on pl. 149, fig. 4. It is more elevated in the spire, and the aperture is more ovate than in the type, the columellar margin descending more obliquely. It measures: major diam. 5, alt. 2°5 mm.

Yet another form is referred to on page 391. Nineteen ‘Specimens were collected by Godwin-Austen in the Jatinga Valley, North Cachar Hills, which are higher in the spire, with coarser ‘sculpture and smaller umbilicus, while the peristome is devoid of the notches on the outer margin. The same form was obtained by W. Chennell in South Sylhet, North Khasi and Garo Hills.

“Most nearly allied to f. wmbonalis, B., from Pegu. It is distinguished from that species by its more raised spire, smaller size, shorter sutural tube, and shallower suture, by its Jess oblique mouth and non-descending last whorl, and by its duplex slightly expanded peristome, which contrasts strongly with the broadly reversed lip of f.geumbonalis. That species also has the upper whorls much more closely, but less sinuously costulated than are those of A. ingrami, In the subangulation of the last whorl at the periphery there is some resemblance to the little Thayet Myo

A. seulptilis, B., which, however, is easily distinguished by the characters of its crenulated peristome, besides other peculiarities.” (Blanford.)

“Larger than the Khasia A. prosectus, from which it is abundantly distinguished by the characters of the aperture, the less mucronate spire, its peculiar striation and lustre, shorter sutural tube, and the greater inflation of the last whorl. In prosectus the space between the constriction and the aperture is suddenly tumid near the constriction, the swelling decreasing towards the peristome ; in physts the swelling increases gradually towards the mouth, which is not inclined to be so very oblique. There are faint indications of spiral sculpture evident in the facet-like appearance of the surface. Within the umbilicus, near the inflated part, every fourth or fifth of the scarcely elevated strie (which would elsewhere be hardly distinguishable except for their white opacity on the hyaline ground) is raised into a knife-like edge.

etn size and form A. physis nearly approaches umbonalis ; but the colour, opakeness, great solidity, and the more moderate inflation of the last whorl, in addition to the more remote con- striction, and the very different sculpture presented by the Burmese species, preclude any danger of confounding it with its Himalayan ally.” (Benson.)

“This shell is allied to A. nodatus and dumsengensis, but the expanded part of the last whorl behind the aperture is smoother, with only an indication of wrinkling. It is more closely wound than the latter, and the aperture differs from both in its squarer form and angulation below.

“Specimens from the Lhota Naga Hills (pl. 48, fig. 2) differ slightly in being larger and in the expanded portion being more

Original description :—‘ Shell moderately umbilicated, de- pressedly turbinate, rather thin, translucent, pale horny or white, epidermis of former colour, peeling off in old shells, with very fine indistinct costulation throughout, fine close ribbing on the swell of the last whorl. Spire depressedly conoid, apex very blunt, suture well impressed. Whorls 4, rounded, the last moderately swollen, constricted close to the base of the sutural tube, with a marked subvertical ridge just behind the mouth. Constriction smooth, sutural tube long, rather thick; aperture oblique; peristome round, deeply waved on the upper and outer but not on the columellar margin, outer lip smail, slightly expanded. Operculum multispiral, concave in front, with a small projecting boss at the back. Animal pale coloured, tentacles dark brown.

‘Major diam. 0:18" [4:5 mm.]; minor diam. 0-16” [4 mm.] ; alt. O11" [2°75 mm.]; diam. of aperture 0:08” [2 mm.]; sutural tube 0°075"' [1:9 mm.].”

Hab. India: Mokarsa, N.W. Khasi Hills; Hengdon Peak, Burrail Range, North Cachar, 5000 ft ; Latinga and Diyung Valleys; Lhota-Naga Hills (Godwin-Austen).

Near ud. plectocheilus, but much larger, the ridge more distant from the peristome and the latter more expanded. In some specimens the edges of the outer whorls in the operculum are much raised and bent inwards as in Cyathopoma.

«No appreciable difference can be found between the western and eastern shells, one only, that in the latter the last whorl behind the aperture and within the umbilicus is more rounded— in the western there is a decided keel. From the Lhota- Naga Hills, one example must be considered a variety; it is closer wound with closer umbilicus and whorl subangulate near it.” (Godwin-Austen.)

“The constriction of the last whorl is near the aperture, with- out any intermediate ridge or swelling, in this respect showing an affinity with amphoru and urnula. In the crenulation of the peristome it exhibits an analogy with sculptilis of the normal group, in which the crenulations are tweive in number, with the origin of the sutural tube remote from the aperture.

“The speeimeus examined are all weathered and bleached. It is a singular circumstance, that each of the three natural sections of Alyceus should have an analogical connexion through the plicate peristomes of seulptilis, plectocheclus, and crenwlatus.” (Benson.)

“The specimen figured, from Damsang, Western Bhutan, differs somewhat from specimens I have come across in Blanford’s collection from Namgu and Lingtam, Sikhim, in having much stronger higher costulation.” (Godwin-Aasten.)

By the operculum alone it can be at once distinguished, and it is besides a much smaller shell.

‘A dwart variety occurs on Shengorh Peak, only 0°09[2°25mm.] in. alt., not so expanded near the aperture, and with the plication less developed. On the Tanir Ridge, at 4000 feet, the same

246 OYCLOPHORID,

shell, of ordinary size and with the same character of the aperture, occurs, showing an interesting and gradual change in form ; the operculum is also different, being pale coloured, multispiral, and flatly concave in front. This form is in this respect much nearer to A. digitatus, and might be separated under the title var. subdigitatus.” (Godwin-Austen.)

Subsequently the author appears to have somewhat modified his views with regard to the Shengorh Peak form, for in 1914 he observed that it is a mere variety, differing in its smaller size, more depressed and rounded spire, and finer costulation, at the same time substituting the name var. nana.

“‘ This shell assimilates somewhat, in the character of the con- striction and the expansion of the whorl anterior to it, to A. hebes, Bs.; but in the irregular wrinkled portion in advance of the main ridge crossing the swollen part it differs materially, and presents a most interesting approach to A. notatus, G.-A., of the Dafla Hills, the surface of which is more irregularly wrinkled and pitted : it is not so closely umbilicated, and the aperture is more angulate below. It appears to be a most abundant species.” (Godwin- Austen.)

“Of all the Alycei yet described with plicate peristomes, this exhibits the character in the most exaggerated degree ; the free portion of the lip being prolonged into tive digitiform folds, nearly « millimetre in length. The ridge-shaped fold between the two constricted portions is very abrupt, as in <Alyceus plectocheilus, which species, together with a yet unpublished form found by Major Godwin-Austen in the Khasi Hills, are its nearest allies. In some specimens, taken alive, the costulation has disappeared from the greater portion of the upper whorls, and remains only in patches; so that on a cursory inspection the whorls appear to be smooth and striate; it is most distinct on the inflated portion of the shell.” (Blanford.)

Godwin-Austen refers to two specimens, found in the Blanford collection, with the MS. name fimbriatus. The specimens are bleached and poor, and represent a dwarf variety of A. cigttatus.

Alycaeus (Dicharav) expatriutus, Kobelt, Das Tierreich, Lief. 16, 1902, p. 369, tig. 52.

Original description :—‘ Testa mediocriter umbilicata, depressa, ad antractos internos obsolete, ad ultimum fortius, ad spatium inflatum valde, crebre costulata, corneo-albida, apice diaphane rubella; spira vix elevata, apice obtusa; sutura impressa; anfr. 33 convexi, ultimus ad latus mediocriter inflatus, deinde constrictus ; constrictione longa, medio tumida, glabra ; tubulum suturale pone constrictionem oriens, mediocriter longum, plerumque + peripheriz subaquans, sed nonnullis exemplis brevius; apertura circularis, obliqua, juxta anfr. penultimum retro curvatum ; perist. duplex ; internum breviter porrectum, continuum, externum expansum, interruptum, columellari nargine strictum. Operculum corneum, distincte multispirum. Antr. 7-8 planulatis, externe percon- cavum, nucleo centrali interno prominente papillari.

Hab. India: Neddoowuttom Ghat, Nilgiris; Anamullies and South Canara (Blunford) ; Shevroy Hills (Ainq).

“This species appears to be more depressed in the spire than any other of the genus, except perhaps the Bornean A. spiracellum, A. Ad. & Reeve. Its nearest Indian ally is A. strangulatus, Hutton, and in size it is intermediate between that species and A. stylifer, Bens. It belongs to the section Charax ot Benson, having a wide strangulation behind the peristome, crossed by a swollen ridge, which, however, in A. ewpatriatus never presents the sharpness so remarkable in A. stylifer and hebes, but is rather a broad tumid space separating two narrow constrictions. The sutural tube is variable in length, sometimes being nearly as sharp as in A. strungulatus, in other specimens as long as in A. stylifer ; the latter being the usual case, the former the exception, but both occur in perfectly fresh and full-grown specimens.

“From A. strangulatus the species is distinguished by its greater size, more depressed form, more oblique aperture, by the recur- vation of the peristome at its junction with the penultimate whorl, the longer sutural tube, the greater distance of the ridge crossing the constriction from the mouth, and the closer sculpture. From prosectus and stylifer the characters of the peristome, which is simple in stylifer and expanded at the columellar margin in prosectus, besides the smaller size of A. expatriatus; from hebes and gemmula the slightly prominent ridge not recurved and the depressed form, afford abundant grounds for distinction. A. spiracellum of Borneo is probably closely allied, but we are only acquainted with that shell by its description. Judging therefrom, A. ewxpatriatus should be distinguished by its smaller size, more narrow umbilicus, greater bluntness of the ridge in the constriction, and, in general, by the greater length of the sutural tube, a character which, however, is evidently, from its variability in this species, of less value than has hitherto been supposed.

ALYO BUS. 251 “2... The animal is small and colourless; the body very short ; the sole undivided; tail short and rather pointed ; tentacles short, yellowish ; muzzle blunt, not elongated.” (Blanford.) Blanford in 1861 (J. ¢.) mentions a variety having been obtained by Mr. King from the Shevroys, a group of hills about 30 miles N. of the Kolamullies. It only differs from the Nilgiri form in size, measuring in its two diameters 54 and 43 mm. instead of 43 and 33. Godwin-Austen records two specimens from the Shevroy Hills, larger than typical forms, the largest measuring 5°5 mm. major diameter. Both have short sutural tubes, but the ridge crossing the constriction varies in elevation throughout. He also mentions specimens from the Anamullies, in the Beddome collection, the largest of which measures 6 mm. in major diameter, while in all the ridge is quite high and the sutural tube short.

“This shell is nearly allied to A. expatriatus, Blanf., of the Nilgiris, but distinguished principally by the possession of a recurved ridge upon the constriction, somewhat similar to that in A, hebes, Bens.and A.gemmula, Bens. Other differences are, the flatter suture and more oblique mouth, caused by the greater descent of the last whorl in A. foote:, while the swelling at the side of the last whorl is somewhat greater, and the constriction more marked.

“From A. hebes and A. gemmula, the present species is easily

252 CYCLOPHORIDA.

distinguishable by its flat spire, besides other characters of sculp- ture, etc. The ridge on the constriction A. foote: lies back on the top of the whorl, and meets the peristome at the base of the right margin: in the other two species the ridge is more at the side, and meets the peristome at the bottom.” (Blanford.)

Godwin-Austen publishes one of Blanford’s numerous and valuable field-notes to the following effect :—

Alycceeus footei from the Wynaad only differs from the Shevroy type in the spire being a little higher and the constricted portion of the last whorl between the swollen part and the mouth rather longer. The ridge on the constriction is reverted. Diam. 5 x 43, axis 3.”

He also finds in the Blanford collection a variety of A. foote from the Kadur District, Mysore, having the ridges across the constriction high and narrow, not reverted, while in the same collection five specimens from ‘linevelly the same ridge is very low and inconspicuous.

Hab. India: Teria Ghat, Khasi Hills (Zheobald).

“This species occurs on rocks, and is distinguished by the structure of the aperture from the small Bornean A. spiracellum, A. & R. In the latter species, moreover, the rib behind and above the aperture is nearly parallel with the peristome, whereas in A. hebes it looks like a hoop which had fallen backwards on the whorl. In both species it takes its rise at the right side of the peristome, and ends at the suture, corresponding with an internal sulcus.” (Benson.)

“A. humilis resembles somewhat the minute A. armillatus, B., but differs in the very much greater distance to which the strongly marked costulation upon the tumid portion of the last whorl is carried back from the constriction, the distance being in both species proportional to the length of the sutural tube. A. humilis is futher distinguished by its longer constriction, by the descent of the mouth, and the greater tumidity of the last whorl. The colour, as in many Alyce, is probably not quite constant, some specimens being white and translucent.” (Blanford).

Alycaeus (Dicharax) khasiacus, Kobelt, Das Tierreich, Lief. 16, 1902, p. 872.

Original description :—* Shell subturbinately depressed, openly unbilicated, translucent, varying much in colour from horny amber to pink- and dark red-browns; a shining surface, very finely striated under lens, very minute ribbing on the swell of the last whorl; in some specimens a faint costulation is seen. Spire depressedly conoid, apex very blunt, often darker coloured than rest of the shell. Suture impressed, whorls 4, well rounded, last moderately swollen, sharply constricted and again enlarging into two vertical ridges, that nearest the mouth being the least developed, and only extending across the upper portion of the whorl, being cut off by the peristome. Constriction smooth, sutural tube very short and thick at the base. Aperture oblique, round, slightly angulate above. Peristome more or less distinctly double, inner continuous, outer slightly expanded. Operculum multispiral, very concave in front, convex behind, no boss.

“Major diam. 0-15” [3°75 mm.], minor diam. 0°13” [3-25 mm.]; alt. 0:09" [2:25 mm.]; diam. of aperture 0:07" [1:75 mm.]; sutural tube 0025" [0-65 mm.].”

Hab. India: Khasi and Jaintia Hills; Cherra Poonjee, Assam (Godwin-Austen). Burma: Valley of the Barak, Munipur (Godwin- Austen).

ee The very short tube and very fine ribbing on the last whorl, and the plain surface of the rest of the shell, combine to make this a very distinct and well-marked species of the genus Alycceus.

“This species, only smaller in size and not with the red coloration of the typical Khasi Hills form, occurred on the Trigonometrical Hill Station of Angaoluo in the North Naga Hills, It measures 3 mm. in major diameter as against 3°5 mm. of the

type shell. I have true chastacus from Jawai in the Jaintia Hills, from Mairang and Shillong. I also found it in the valley of the Barak, Munipur, and at Asalu in the North Cachar Hills.

‘“ Among a large series of this species variation may be noted in a specimen here and there. The two ridges behind the peri- stome are only slightly developed, blend and nearly disappear. Such examples might be considered, if singly and separately collected, to be a different species. The short sutural tube then shows what the true relationship is.” (Godwin-Austen.)

“The dimensions given are those of the largest of four speci- mens. ‘ihe strenuously vandyked plication of the incrassate edges of the porrect dextral side of the peristome is a remarkable feature in this minute species. It recalls the curious frill in Pterocycios bilabiatus, Sow., but in a more exaggerated guise, not- withstanding the smallness of the shell. The edges of the folds are thickened and slightly reflected. Its smaller size, sculpture, and wider umbilicus, and, above all, the mode of constriction, prove that it is not an exaggerated form of crenulatus. The deceptive appearance of the ridge or crest at first induced me to class the shell with Diory«; but a closer investigation of the mode in which the ridge was attached to the true peristome, and a view of the internal sulcus, revealed the true position of the species.” ( Benson.) ,

“This species is allied to the last described [-A. succineus] but is distinguished by its higher spire, less marked sculpture, by the strong ridge on the constriction, and by the more polygonal aperture. The incision of the base, however, is slighter, and, in this species, accompanied by a slight corresponding projection beneath, which represents, on a small scale, the large ear-like basal process in A. prosectus, Bens., from the Khasi Hills. The inner peristome of that species also has a slight basalindentation within the aperture.” (Blanford.)

‘It is related to the Burmese A. umbonalis and to A. stranyu- latus, Hutton. Inferior in size to the former, it is easily distin- guished by its sculpture and by the peculiar development of the outer lip at its insertion and base, while the narrow columellar lip gives an appearance of artificial truncation to the peristome at that part. In the variety the internal lip is not developed. The margins of the whorls in the operculum are not conspicuously raised as in A. umbonalis.” (Benson.)

Godwin-Austen records a variety—unnamed—from Cherra Poonjee, in the Ponsonby collection, which is smaller than the usual typical form, and though quite similar in shape, shows a decided tendency to crenulation on the outer margin of the peri- stome; a similar tendency he observed in other species.

Some specimens from ‘leria Ghat he noted being as much as 8mm.in major diameter, varying much in size even from this locality, fully-grown specimens being only 6 mm. From some places all are small; G. Nevill distinguished them as var. minor.

From Rywuk, at the foot of the Garo Hills, he found the form to differ considerably in having a tendency to a crenulate peristome.

22 CYCLOPHORIDA,

“Some of the peculiarities of this species, such as the canaliculate base of the peristome, and the two or three small plaits on the constrictions are repeated in the next described Ld. polygonoma}. The plaits or ridges just referred to, although they have corresponding internal hollows, are scarcely so promi- nent as those forming the sculpture of the upper portion of the shell. They are nearer to the mouth than to the rise of the sutural tube, and rest upon a tumidity which is scarcely sufficiently pronounced to enable the species to he assigned to the section Charaxv of Benson, although it exactly represents the well-marked ridge in the undermentioned species A. polygonoma. The sutural tube is, in one specimen, somewhat short of the typical length.” (Blanford.)

Hab, India: Khasi Hills (Theobald).

“T received two specimens of this species from Mr. Theobald as A. hebes, Bens., of which they were supposed to be young shells. They, however, prove, on closer examination, to be fully grown and distinct, the slight swelling in the centre of the constriction contrasting strongly with the high recurved ridge in A. hebes. This alone would shew the present to be a different species, but it is also distinguished by its lower spire, narrower umbilicus, smaller size, and thinner and interrupted peristome, the last character not occurring in any other species of the genus. The well-marked distant costulation of the upper whorls of A. theobald2 is entirely wanting in A. hebes. The operculum of the latter does not appear to have been described. A single specimen in my possession is dark horny, indistinctly multispiral, extremely con- cave in front, and convex, almost conical, behind, and deficient in the central boss so prominent in most Alyce.

Although there-is,a swelling in the centre of the constriction in A. theobaldi, it does not amount to a marked ridge, such as characterizes the typical forms of the section Charaa of Mr. Benson, e.g. A. stylifer, B. It is consequently not clear whether this species should be classed with the members of that section, or with those of the typical group. Several species indeed tend to connect these two subdivisions, which more recent discoveries have rendered less distinct than they appeared to be when first described.” (Blanford.)

“Tbis species is variable in size, retaining its principal characters. Thus from the North Khasi Scarp, near Maotherichan ‘Trigonometrical Station, I obtained eight specimens far larger than those from Cherra Poonjee. Three of the largest measure 5 mm. in diameter as against 4 from the last named locality. It was found at Shillong and Jawai.” (Godwin-Ausien.)

Original description :—‘Is of the same form as A. theobaldi from Cherra Poonjee and the Garo Hills, only that while the operculum in the latter is exceedingly closely wound, quite smooth in front, and black (and I have examined some dozens of shells), in the former the concentric whorls are wider apart, have a central circular hollow space, and are white. The ribbing of the swollen portion in the Dafla shell is exceedingly fine, and this, I note, is acommon character, holding good almost without exception, of all the species in the Dafla Hills.” (Godwin-Austen, 1876.)

Hab. Burma: Fort Stedman (IVoodthorpe).

“The most distinguishing character of this shell is the extremely fine close regular costulation next the sutural tube, which, in most species of the genus, is strong and well defined; this character is met with again in species of the Abor Hills, such as A. aborensis, ete. This in conjunction with the fact that so large a proportion of the species in other genera inhabiting the Abor country are not found in Western Assam, is an indication of topographical connection between the Shan area and the Tsanspu drainage-system far back in geological time, closer, more direct, and unrestricted than now exists. There are grounds for thinking that the high snowy range at the head of the Irrawaddy, together with the well defined orographical feature the Assam Range to the west, may be a comparatively recent elevation compared to the main mass of the Eastern Himalayas.” (Godwin-Austen.)

“This is one of the most elevated in the spire among the known Himalayan Alycewi. The specimens sent are all weathered, but present no evidence of any considerable sculpture or colouring. The very short sutural tube is a character shared by otiphorus and constrictus; aud altogether the shell is deficient in prominent features, although perfectly distinct from any of its allies, espe- cially in its apertnre (sinuous, aud at its upper angle emarginate), its wider umbilicus, plainer sculpture, and more compressed whorls.” (Benson.)

‘‘A Burmese representative of the little Darjiling group of Alyeei, which comprises A. constrictus, B., A. bembew, B., and A. otiphorus, B.A. graphicus, although much more globose than any of the others, is in some respects intermediate between constrictus and otiphorus, resembling the tirst in size and some- what in form, and the latter in the reflexed left edge of the outer peristome. This character, however, is by uo means so much developed in the Burmese as in the Darjiling species. The present has a more marked sculpture than either of its three allies and differs from them also in the very slight approximation of the costulation behind the constriction.

In form it approaches A. amphora and constrictus, and, like the latter, which belongs to the same type in the mode of constriction, it is. remarkable for the shortness of the sutural tube, but is at once distinguished by the process of the peristome at the umbilicus.” (Benson. )

“This species is quite new; it might be at first mistaken for a sinall variety of A. pyranudalis, Bs., from the Tenasserim Valley, but the sutural tube is in that species very thread-like and nearly 3 millim. in length; the aperture is also very different in form, and not so simple and circular.” (Godwin-Austen, 1888.)

“With the very different pyramidal form of shell as compared with A. constrictus, etc., the presence of the short club-like sutural tube puts this species in the section Cyclorya. On the other hand, in the shell-character combined with type of sculpture, it is like species in the neighbouring country to the east and south, A, pyramidalis and A, yibbus.” (Godwin-Austen, 1914.)

“The animal was very difficult to observe, on account of its extreme shyness and minute size. Only a very small portion of the body was extruded from the shell. The foot is very short and apparently rounded, but could not be seen fairly, as the animal would not crawl up a glass but appeared to endeavour to hide itself amongst decayed leaves. ‘The tentacles are short and blunt, the eyes at their outside base, rather high in position, but not nearly so much as in the Aciculacee. The whole animal is white and translucent, the eyes appearing as black specks, perfectly sessile. After two or three failures I succeeded in examining an operculuin by breaking back the whorls of a specimen carefully until I came to it. It is lodged at the constriction in the last whorl, as long since suggested by Mr. Benson, and is distinctly horny, concentric, and paucispiral, resembling the figure of the operculum of Diplommatina follicudus given in Adams’s ‘Gen. Ree. Moll.’ ‘This entirely confirms the views I long since expressed as to the close aflinity of Opisthostomu to Diplommatina, and shows the former, moreover, to be nearer to the typical costulate Diplommatine of the Himalaya than to the smooth or spirally lirate species (Ariniu, H. & A. Ad.) of Hindustan, as the latter have the spiral structure apparently obsolete... .

OPISTHOSTOMA. 299

“The characters which serve to distinguish Opisthostoma fair- banki from O. nilgiricum are :—

1. The greater exsertion and smaller excentric deflection of the two apical whorls of O. fairbanki.

2. The simple expanded peristome and subtrigonally rounded aperture—O. nilgiricum having a non-expanding duplicate peri- stome, the outer portion retro-relict, and a circular aperture.

3. The more distant sculpture.

4. The manner of curvature of the last whorl, the posterior bend of which is much more acute in the present species. In O. nilgiricum the posterior haif of the sigmoid curve of the last whorl is more open than the semicircular curve nearer the aperture, the nmbilicus being fully exposed within the former. In 0. fairbanki the anterior curve is the more open, and the last whorl just in front of the posterior half of the curve passes across and completely conceals the umbilicus.

“T have with some difficulty, detected in O. fairbanki the minute decussating striz observed by my brother between the costulations in O. nilgiricum. They are very difficult to see, even under a high power and strong light, and appear to be frequently obsolete. Lf cannot detect them in my specimen of O. nilgiricum, which is in good order.

The bluntly trigonal form of the aperture in O. fairbanki does not appear to be quite constant ; the mouth in some specimens is nearly round.” (Blanford.)

‘Long. 3, diam. major 3, min. 2 millim. Ap. diam. cum perist. 14 millim.”

Hab. India: Bramagiri Hills, Wynaad (Beddome).

“Shell perforated, conoidly ovate, white or pale reddish in colour, with sub-distant oblique filiform costulation, which becomes closer on the Jast whorl: beneath a microscope there is very fine close spiral striation, very difficult to detect in general, as in other species of Opisthostoma and many Diplommatine, Spire elongately conoid with convex sides, the apex rather acute, suture deep. Whorls 54, convex, the apical ones not excentric as in the other Indian species; the penultimate whorl very little larger than those above it. The last whorl is constricted as usual. In front of the constriction it is deflected inwards, but less sharply so than in O. fairbanki, and it does not conceal the umbilicus, the curve being more asin O. nilgivicum. Aperture reversed, nearly circular, almost vertical, having scarcely any inclination upwards. Peristome attached for a short distance only, touching both the penultimate and ante-penultimate whorls, double, both portions expanded, the outer more broadly reflexed, and interrupted for a short distance where attached, inuer peristome continuous.

‘This is the largest form of the genus yet met with, exceeding even the Labuan species O. crespigni, H. Ad. It is much more pupa-shaped than that kind is, but much less so than the two previously described Indian forms, from both of which it may be easily distinguished—by the apical whorls not being excentric, as well as by its much greater size.” (Blanford.)

“J some years ago received a specimen of this species from Mr. Thevbald as D. polypleuris, Bens. Ou comparing the series ot Diplommatine collected by Captain Godwin-Austen with Mr. Benson’s description, it is evident that the type of that species belonged to a different form, found abundantly by Captain Godwin-Austen with the present species on the Maotherichan ridge, part of the northern scarp of the Khasi Hills, and dis- tinguished from the present form by its much stronger sculpture, less conical spire, deeper suture, and rounder mouth. It is a smaller form. Mr. Theobald’s type specimens of D. polyplewris were from Nanclai, also on the northern portion of the Khasi plateau. D. austeni varies considerably in the sculpture of the lower whorls, which are in most specimens quite smooth. One individual sent is considerably more tumid than the type, but presents no other difference of importance.” (Blanford.)

“Independently of its smaller size and stronger costulation, this shell is distinguished from D. pachycheilus by its foveate rimation behind the thin columellar lip, and by the retrolict variciform second peristome, which is remote in its course, on the right side, from the thin actual peristome, but joins it below the ambilical cavity. In D. pachycheilus the peristome is thickened and bifurcate at the insertion of the outer lip, and there is no

The last whorl ascends more conspicuously in front than in D. pachycheilus, although it rises considerably also in that shell—a feature which I omitted in the description given in the Annals’ for 1857. ‘The costulation ot D. pachycheilus is very variable ; ii some specimens it disappears in the lower whorls, in others on the upper ones only ; occasionally it pervades the whole surface.” (Benson.)

Original deseription:—“ Shell dextral, ovately fusiform, moderately thick, pale horny. Sculpture very fine, almost disappearing on the last two whorls. Sides of spire moderately flat. Whorls 7, penultimate and antepenultimate the largest, the last ascending slightly. Constriction in middle of aperture, which is circular and vertical; columellar margin rounded, tooth moderate. Peristome simple, double, rather strongly formed, the inner lip continuous.

Alt. 0°15 (8°75 mm.], diam. 0°70 inch [? 0:07 inch=1-75 mm. ].

“This shell is very similar in form to D. austeni, W. BIf., from the Khasi Hills, but it is much larger, that shell only being 0°90 [? 0-09] inch in length, and the two last whorls are not so smooth and show slight traces of sculpture.” (Godwin-Austen, 1876.)

“Comparing this more closely with the form from the Khasi Hills, it differs very much in its general shape, being much smaller below, the antepenultimate being much larger in pro- portion to the penultimate ; the apex is more attenuate, and the sculpture differs. It must therefore be distinguished as a species.” (Godwin-Austen, 1886.)

“There was one solitary specimen in my collection of this species from north of the Burrail, and 6 specimens, but smaller in size (4-5 millim. in height of spire), from the peak of Shiroifurar, in the Lahupa-Naga Hills, north of Munipur. Mr. Aldridge’s collection contains a large number, and I have selected the type out of these.

“On the boss of trap rock near the village of Phunggam I found a number of a small variety, 45 millim. in height of spire, but differing in no respect, except in size, from the typical species, only that they are all of a pale sea-green tint.

“The same form occurred on Kopamedza Peak, with this difference, that the constriction was more to the right, directly over the outer margin of the peristome. [*rom Prowi, specimens were still smaller in size, 3°8 millim.” (God'win-Austen.)

“This very interesting species differs widely in form from the only previously described sinistrorse Diplommatina inhabiting India, D. huttoni, Pfr., more widely than it does from some of the reversed forms met with in the Oceanic region. It shews a con- siderable resemblance in form to D. martenst, H. Ad., of unknown locality, figured in the Proc. Zool. Soc. for 1866, but which is said by its describer to belong to the section Diancta of Martens, characterised by a constriction at the back of the penultimate whorl. In D. gibbosa, as in most Indian Diplommatine, there is a slight tendency to constriction in front of the penultimate whorl, to which an internal rib appears to correspond, but which is covered and concealed to a great extent by the parietal callus of the peristome.” (Blanford.)

Hab, India: Mussoorie, N. W. Himalayas (Godwin-Austen).

In 1867 the late R. J. Lechmere Guppy recorded the finding of this species in Trinidad, suggesting its migration—together with Ennea bicolor, Hutton—across the Tertiary Atlantis. The late William Blanford discussed this question at great length in 1868 (loc. cit.) and suggested the possibility of these molluscs having been transported with living plants, as others are well known thus to have been transported. Lieut.-Col. Godwin-Austen has com- pared specimens of D. huttonz, from the typical locality Mussoorie, with eighteen specimens from Trinidad, lent to him by the late Sir Rawson Rawson, and he found that the two forms were specifically distinct, and he has renamed ‘and described the Trinidad shell as D. occidentalis *.

The question, however, as to which of the Indian species has been transported to America still remains unsolved. If the Trinidad form assimilated to any of the known species, Lt.-Col. Godwin-Austen, with his intimate and extensive knowledge of the Indian Fauna, would have been able to detect it. The Western Hemisphere being altogether outside the range of this genus, there can be no doubt that the species must have been carried across through human agency. The well-known case of Eulota similaris may be cited in this connection, this species having become distributed by similar means over a great part of the world. (Cf. Fauna Brit. India, Mollusca, vol. ii, 1914, p. 201.)

Height 22 mm., diameter 13 mm., diameter of aperture with peristome, 3 mm.”

Hab. India: near Jawai, Jaintia Hills, 4500 ft.; West Khasi Hills (Godwin-Austen).

“This species is very near D. gibbosa, from the same region, and thus affording a second instance of a type intermediate between the dextral forms D. pachycheilus, D. diplocheilus, etc., and the sinistral forms from the Solomon Isles, ete. It is distinguished readily from D. gibbosa by its more regularly ovate form, its costulation, and the even, non-sinuated margin of the inner peristome.

“Since the transmission of specimens of Diplommatina, pub- lished in the Journal for 1868, to Mr. W. Blanford, I have been fortunate enough to discover this species again. As the above quoted figure, on pl. iii, of the ‘Contributions to Indian Malacology, no. ix,” was taken from a single shell, subsequently broken, the species remained unfortunately unnamed and un- described.” (Godwin- Austen.)

Diplommatina (Diplommatina) jatingana, Kobelt, Das Tierreich, Lief. 16, 1902, p. 436,

Original description :—“ Shell dextral, ovate fusiform, solid, pale corneous ; specimens, when young, often of a bright sienna, diaphanous; rather finely and sharply costulated on the four whorls near the apex, becoming fainter below, and from the ante- penultimate to the body whorl almost smooth, or with only a faint trace of ribbing; spire conic, sides flattened, apex rather acute, suture slightly impressed below ; whorls 73, the ante-penultimate the largest; penultimate whorl slightly coustricted at 3 turn behind the peristome, last whorl ascending chiefly behind the constriction ; aperture sub-vertical, broadly euriculate ; peristome solid, double, columellar margin straight, right-angled at base; the usual tooth, large, coarse and blunt, sometimes descending ; lips very slightly expanded, outer more so than the inner, this last continuous, forming a strong callus upon the penultimate whorl.

* Animal pale, almost colourless, tentacles brown, labial ribbon long and tapering.

“Height 4 mm.; diameter 24 mm.; diameter of aperture 1 mm.”

Hab. India: hill at the junction of the Kayeng and Jatinga Rivers, N. Cachar Hills (Godwin-Austen).

“This is a very handsome and peculiar species, and one of the largest I have obtained in these hills; it was only found on the above isolated hill, where it was abundant. J have named it after the large river, the Jatinga, that flows below. The species is nearly allied to D. blanfordiana and D, semisculpta: it is, however, somewhat more tumid, and has shallower sutures than either of these forms ; and while it has not the distant retro-relict peri- stome and rimation of the former, it appears to be less sharply angulated at the base of the peristome than the latter. But the most distinctive character is the position of the slight constriction of the penultimate whorl which, instead of being in front of, or above, the aperture, as in D. blanfordiana, D. semisculpta, and D. pachycheilus, is at a considerable distance, about 7 turn behind it. Hence the suture of the last whorl rises rapidly behind the constriction, runs for a short distance in front of it parallel with the preceding suture, and finally again ascends to the margin of the peristome.” (Godwin-Austen.)

‘‘This shell is easily distinguished from its congener D. pachy- cheilus, Bens., by the greater tenuity of the antepenultimate whorl, the absence of sculpture on the lower whorls and the more prominent angle at the left lower corner of the peristome. This last character in D. semisculpta is rather stronger than appears in the figure. The present species is much more closely allied to D, diplocheilus, Bens., which it resembles greatly in sculpture and form. The principal distinction is in the peristome which is much less developed in D. semiseulpta, the parietal callus being quite thin and appressed instead of standing out from the last whorl as in that species. The monthalso is larger in proportion, the angle at the base of the columellar margin more salient, and the spire more acuminate.” (Blanford.)

Hab. Burma: Damotha, near Moulmain (Stoliczka).

“This species is somewhat allied to D. puppensis, Bif., differing from it by its constant smaller size, more tumid or convex, and more widely costulated whorls, and by the aperture being at the columellar base rounded or nearly so, instead of deeply angular and canaliculate, as it always appears to be in puppensis.

“The present species was found to be very common on the perpendicular limestone cliffs at Damotha, especially in localities where a little water trickled down the rock. ‘The animals seemed to feed on the minute alge which were growing in the locality.” (Stoliczka.) ,

“Independently of sculpture, the species may be distinguished from O. distermina by its less globose form, and by the absence of the keel around the periphery; from 2. andersoni by its much smaller size, wore rounded whorls, and by the absence of the keel; and from #. pallida by rounder whorls, by colour, and by its rather more turreted form.” (Blanford.)

(There is also, beneath the lens, a faint indication of minute spiral striation, but I am not sure that this is not an individual peculiarity.) Spire conical, apex acute, suture impressed. Whorls 6, slightly convex, the last rounded at the periphery and below, radiately striated around the perforation. Aperture nearly vertical, ovate, shorter than the spire.

Original description :—* Shell not quite so large as the preceding (A. tersa and A. hyalina], with less convex whorls, less globose last whorl, and less open umbilicus; in these respects it is nearer A. hyalina; the last whorl is, however, more produced and con- tracted than in A. hyalina.

Long. 14; diam. 1 mill.”

Hab. Nicobar Is. : Katchall (Stolizcka).

“The shell is of a silky, translucent and shining texture, with 5 almost cylindrically turreted whorls, the last a trifle compressed atthe periphery; the umbilicus is exceedingly narrow and partially overlapped by the thickened peristome, which here and there, under the lens, clearly shows a duplex character; the aperture is very small, unusually broad in proportion to its height, and almost circular, with the margins almost but not quite con- tinuous.” (Nevzll.)

‘¢ Major diameter 6, minor 5, axis 33 millem.” (Blunford.)

Hab. Burma: Ramri Island, Coast of Arakan.

A smaller variety, measuring—major diameter 5, minor 41, axis 3 millim., is mentioned as being abundant in the southern portion of the Bassein District.

Stated to be related to A. merquiensis, Pfr., and H. andamanica, Bens., but smaller than either, mainly distinguished from the former by the absence of the close spiral striation, so marked in that species, and from the latter by different colouring, higher spire, and closer sculpture.

While merging this species as a subspecies of H. merguiensis in 1905, Dr. Wagner subsequently reduced it to a synonym of H. nicobarica *.

Cyclostoma planorbulum, Sowerby, Thes. Conch. i, 1843, p. 110, pl. 25, figs. 83-86.

Originally recorded from Bengal, but reduced to a synonym of Cyclotus variegatus, Swains., a Philippine species, by Kobelt & Méllendorff, Nachr. Deuts. Malak. Ges. xxix, 1897, p. 117 ; id. Cat. Pneum. 1899, p. 30.

Cyclostoma punctatum, Grateloup, Act. Soc. Linn. Bordeaux, xi, 1841, p. 440, pl. 3, fig. 10 ; Pfeiffer, Conch.-Cab., Cyclostomaceen, 1847, p. 40, pl. 5, figs. 12,13; id., Mon. Pneum. 1852, p. 67; Kobelt, Das Tierreich, Lief. 16, 1902, p. 142.

Recorded from Ceylon by Grateloup. China was indicated as its habitat by Pfeiffer on the authority of Sowerby. Kobelt gives Hong Kong.

Cyclostoma tricarinata, Lamarck, Hist. Nat. Anim. s. vert. vi, 2, 1822, p. 144; Sowerby, Thes. Conch. i, 1848, p. 120, pl. 26, fig. 122 (tricarinatum) ; Pfeiffer, Conch.-Cab., Cyclostomaceen, 1847, p- 25, pl. 3, fig. 8 (not pl. 4, figs. 16, 17); id., Mon. Pneum. 1852, p- 198; Suppl. 2, 1865, p. 125; Nevill, Hand List, i, 1878, p. 305.

Sowerby gave India as habitat, but Pfeiffer in 1865 (J.c.) indicated Madagascar.

Cyclostoma undulatum, Sowerby, Thes. Conch. i, 1843, p. 99, pl. 23, figs. 29, 30; Pfeiffer, Conch.-Cab., Cyclostomaceen, 1848, p- 97, pl. 12, figs. 24-26; id., Mon. Pneum. 1852, p. 223; Morelet, Ser. Conch. 1860, p. 100.

Originally recorded from Bengal by Sowerby. Pfeiffer in 1852 (1. c.) gave Mauritius as the habitat on the authority of Petit and Benson.

Pterocyclus biciliatus, Mousson, Land- u. Siissw. Moll. Java, 1849, p. 49, pl. 20, fig. 9; Pfeiffer, Zeit. Malak. viii, 1851, p. 187; Theobald, Cat. Shells Brit. India, 1876, p. 38; Nevill, Hand List, i, 1878, p. 263.

Originally recorded from Java, Pfeiffer indicated Burma as its habitat, but Borneo, given by Nevill and Theobald, is more likely to be correct.
