A LIST OF TnE SPECIES OF LAND 3IOLLTJSCA COLLECTED BY MR. W. DOHERTY IN THE MALAY ARCHIPELAGO ; "WITH DESCRIPTIONS OF SO3IE SUPPOSED NEW SPECIES AND VARIETIES. By HUGH FULTON. Mead llth Xovcmler, 1898. PLATE XI. THE shells dealt "with in this paper were part of a collection made by Mr. William Doherty some three or four years ago. The duplicates having come into my hands (the first set having been acquired by the British Museum), I take this opportunity of giving a list of the species I have succeeded in identifying, and of describing some ne\r forms. Several species still remain to bo worked out. In the comparison of the new forms I have been greatly assisted by Dr. 0. von Mollendorff, especially with the minute and, therefore, more difficult ones. To Mr. Edgar A. Smith, Assistant Keeper of Zoology at the British Museum, I am also indebted for much valuable aid.

DESCRIPTIONS OF NEW SPECIES.

1. SIREPTAXIS TLAXUS, ii.sp. PL XI, Fig. 2. Shell doxtral, snixliscoidal, depressed, glassy, semi-transparent, concave above a-.d below; smooth except for indistinct lines of growth ; •" *, regularly increasing, the last rounded below, angular above; apcrt-'jre somewhat L-shaped, depressed above, armature con- sisting of 4" j-ee short lamellifonn projections situated on the parietal wall, rip'1 .c and basal margins of the peristome forming a triangle; pcristc ..o thickened and slightly reflected. Diam. maj. 5'5mni., alt. oi body-whorl 2 mm. Hal.—South Celebes. A remarkable species, quite unlike any other of the genus, and very interesting as being the first recorded from Celebes; in fact, except for a young specimen found in Borneo by Dr. von Martens,1 it appears to bo the first recorded from the Malayan Archipelago.

2. CIILORITIS 3ii3iA, n.sp. PI. XI, Fig. 7. Shell discoidal, dark brown, almost flat above, somewhat excavated below, open to about' the width of 2-5 mm.; whorls 4J, convex, slightly channelled at the suture ; poristome slightly expanded, margins joined by a raised and somewhat thickened callous ridge. Diam. maj. 23, alt. 11mm. Hal.—Buru I., Moluccas. This species, save for several slight differences, is a miniature of the large C. Gruneri, Pfr.: the in the latter descends very

low, 'whereas it is only vcr}- slightly descending in our species ; there are also differences in the parietal callus, that of C. Gruneri being much thicker in the upper portion, whereas it is of equal thickness in G. mima; the latter has the spiro very slightly depressed, that of the former is flat. From 0. unguiculadra, Marts., it can ho separated by its smaller size, its raised callus, and its narrower umbilicus.

3. CHLOEITIS SELENITOIDES, n.sp. PI. XI, Fig. 9. Shell depressed, subglobose, openly unbilicated, dark brown; whorls 5, convex, gradually increasing, first three almost flat, last two gradually descending, with obtuse but conspicuous oblique plicate striae ; peristomo white, slightly expanded, margins joined by a some- what thickened callus. Diam. maj. 26, alt. 14 mm. Jlab.—Bum I. A distinct species, easily distinguished from others of tho genus by its zonitoid form. This and 0. mima belong to the hairless forms of Chloritis.

4.. PLAJUSPIRV ADOXARAXA, n.sp. PI. XI, Fig. 12. . Shell depressed, globose, thin, smooth, light horn-colour, umbilicus open to about 2 mm. at its widest part, somewhat constricted behind tho aperture; whorls 3$, slowly increasing, convex, last half-whorl descending about 2 mm.; peristomesubcircular, continuous, broadly expanded, equal to b .If tho width of tho shell, very oblique, a spiral fold just above tb periphery for one-third of a whorl behind tho aperture, an indir cion of another is faintly seen on the basal portion of the peristomo. Diam. maj. 12, alt. 7 mm. Jlab.—Adon :a L, Moluccas. Easily distr guished from P. eudoptyclia, Marts., by its continuous peristome ar . fewer whorls.

5. AnpniDKOHUs CONTRARIUS, Miill., var CRASSA, n. PI. XI, Fig. 8. Tliis is similar in shape to the typical form, but is a much more solid shell; tho columella is thick and round, not thin and "expanded as in the typo ; whilst tho aperture is somewhat higher in proportion to the height of the shell, and tho interrupted oblique colour-stripes of the type are absent on the last whorl of this species. Diam. maj. 20, alt. 40 mm. Jlab.—Timor I. Numerous examples of tho typical form were also collected at Timor by Mr. Doherty.

6. HTPSELOSIOMA DonERTri, n.sp. PI. XI, Fig. 17. Shell dcxtral, triangular, umbilicus deep and moderately wide, almost smooth ; whorls 4, first three small, convex, body-whorl large, somewhat depressed in the centre and keeled above and below, slightly ascending; interior of aperture armed with five teeth, two on parietal wall, two palatal teeth, and one on the columella side of 21G ritOCEF.DIXGS OF IIIE MALACOLOGICAL SOCIETT. the aperture ; peristoruc subcircular, expanded, continuous. Diam. maj. 2*75, alt. 2 mm. Uab.—Tcnimbcr I. Allied to IT. Merelti, Smith, from Ivalao Island, but this species is narrower, the aperture does not project so far from the body-whorl, it is more closely coiled below, and is not perspectively umbilicatcd.

7. PUPA (LEUCOCIIILUS) NIOBE, n.sp. PI. XI, Fig. 10. Shell elongate-oval, rimate, smooth, dirty white ; whorls 5, convex; peristomo oval, thin, continuous, expanded; internal armature of the aperture consists of five plaits, two, rather long entering folds on the parietal wall, one on the columolla side, and two on. the basal portion of aperture. Diam. maj. 1, alt. 2 mm. Uab.—Tcnimbcr I. This has kindly been compared by Dr. von MollendorfF, -who says that the species has some affinity with P. recondita, Tapp.-Can., from the Aru Islands, but is smaller and more cylindrical in form.

8. CiKrcniuii BiLuxinr, n.sp. PI. XI, Tig. 11. Shell elongate, rimate, smooth, glassy, semi-transparent; whorls 5J-, convex, regularly increasing; aperture oval, somewhat oblique; peristome thin, slightly expanded, continued over the parietal wall; a fold on upper part of columella. Diam. maj. 0'75, alt. l"75mm. JIab.—Bali I. I am indebted to Dr. von Jlollendorff for a comparison of this species. Die writes: "Differs from C. Javanum, Molldff., from Java, in being of a more slender form, smaller, and with a narrow aperture."

9. DiriOHiiATixA BALIANA, n.sp. PI. XI, Fig. 16. Shell dextral, thin, oval, transparent white, tinted with a golden colour, acuminate; -whorls 6}, first five increasing slowly, penultimate slightly broader than the last, sculptured with close-set, thin eosta), which are wider apart on the latter part of the last •whorl; a slight constriction above the aperture; aperture circular, erect; peristomo somewhat expanded, continuous. Diam. maj. 1*25, alt. 2*5 mm. Uab.—Bali and Sumba Is. In general form and sculpture very near B. concohr, Quad. & Mdff., from the islands of Luzon and Palawan; but readily separated therefrom by its almost circular aperture and the absence of a columella fold. Dr. von ilbllendorff informs me that he knows of no Javan species that approaches this.

10. DiriOMJUTixA (PALAIXA) MOELLEXDORFFI, n.sp. PI. XI, Fig. 18. Shell dextral, ovate, slightly rimate, either pale yellow or suffused with a pinkish colour; whorls 6, very convex, obliquely striate, penultimate, slightly broader than body-whorl, the latter shortly ascending; constricted just above the aperture, with a prominent FULTON': LAND MOLLUSCA FROM TnE 3IALAT AECIIirELAGO. 217 biilgo or protuberance to tlie left of it; aperture circular; peristome white, thin, broadly expanded, and continued over the parietal wall of the last whorl. Diam. maj. 2-5, alt. 5 mm. Hal.—ITacassar, Celebes. In addition to D. {Arinia) JfiiiaJiassa, Kobolt,1 this and the next are the only species of Diplommafina recorded from Celebes. The nearest allied species is J). {Palaina) clirt/sostoma, Smith, but D. Iloellendorffi is distinctly separated by its less oblong form and its remarkable broadly expanded peristome.

11. DII-LOMITATIXA (PALAIXA) TUMEXS, n.sp. H. XI, Fig. 4. Similar to D. Iloellendorffi, but shorter, the penultimate whorl smoother, compressed and bulging out beyond the body - whorl; peristome larger in proportion to size of shell than in D. Iloellendorffi. Diam. maj. 3-5, alt. 4'75 mm. JTnb.—llacassar, Celebes. This curious form, of which only a single specimen was obtained, may possibly prove to be but an abnormal form of J). Iloellendorffi.

12. DinoiiMATiNA (AEISIA) TALATTTAXA, n.sp. PI. XI, Fig. 13. Shell dextral, oval, thin, rimato, semi-transparent, white shading to golden above, closely and delicately costato; whorls 5, rapidly increasing, last three almost equal in width ; aperture circular, erect ; peristome thin, continuous, with an outer flange or rim. Diam. maj. l'o, alt. 2"75 mm. iTrtJ.—Talaut I. A very pretty and distinct species, readily distinguished from the S. Flores species, D. llanda, Smith, by its having a less number of whorls and by its finer sculpture.

13. DirioHMAiixA (PAXILLUS) L.^VIS, n.sp. PI. XI, Fig. 14. Shell dextral, oblong-conic, dirty white, smooth except for traces of fine oblique strioc on front of body-whorl, non-rimate ; whorls 7, first five almost flat, last two convex; aperture almost vertical, Bubauriform; peristome double, inner portion slightly raised above the outer rim, continued over the body-whorl by a thin transparent callus; two folds on columella, lower one alone visible from the exterior, upper one beginning about half a whorl from the exterior margin of aperture, and continued interiorly ; on the interior side of outer wall, and situated just above the peristome, are two short transverse plaits, which can bo seen from the exterior if the shell bo wetted, whilst on the parietal wall above there is a similar longi- tudinal fold, which can only be seen by breaking the shell open; above and to the left of the columella there is a remarkable tear- shaped protuberance. Diam. maj. 2-25, alt. 4 mm. ITab.~Pulo Laut, S.E. Borneo.

This is the first recorded dcxtral species belonging to the section Paxillus. On breaking open a D. (Faxillus) aihrrsus, Ad., for comparison, I found that in addition to the two plaits on the interior of the outer wall, there is a strong laraelliform plait hanging, as it were, from the parietal wall. I am not aware that this interesting fact has CYCI" been recorded before. 14. CrctornoEus DonEMYr, n.sp. PI. XI, Fig. 5. Shell globoso-conic, moderately thick, umbilicus almost, or entirely coYered by the peristomo, dark reddish-brown, 'with oblique growth- lines crossed by microscopical spiral strife, causing a somewhat granular appearance; whorls 61, COUYOX, last slightly keeled at the periphery; suture somewhat deep; aperture subcircular; peristomo oblique, double, continuous. Diam. xnaj. 18, alt. 18 mm. JIab.—Sangir I. A very distinct species, with a Choanopoma-Viko peristomo.

15. POTIXA (ilouLixsrA) CTLIXDKICA, n.sp. PI. XI, Fig. 1. Shell oblong-OYate, thin, polished, semi-transparent; whorls 5 ; suture distinctly margined ; aperture subcircular, almost vertical ; peristome slightly thickened, a semicircular notch on left margin. Diam. maj. 3, alt. 5-5 mm. Ilab.—Dodinga, Gilolo I. Also a very distinct species, unlike anything I am acquainted with from the Moluccas.

16. CALLIAXELLA FULGIDA, n.sp. PI. XI, Fig. 3. Shell imperforate, polished, ovate-oblong ; suture margined ; spiro oblique; whorls 3J-, rapidly increasing, smooth, two only are visible from the front; aperture circular; peristomo oblique, continuous, slightly thickened. Diam. maj. 3'5, alt. 5-5 mm. //(li.-Bum I. In form very like C. JFaIlacei, Pf., but much larger, not so compressed, broader, and with larger aperture in proportion to size.

17. PCPIXA (POROCALUA) JIIHABILIS, n.sp. PI. XI, Fig. G. Shell acuminate-oval, smooth, shining, imperforate; whorls 5, rapidly increasing, last almost equal in height to two-thirds of whole shell; suture margined; aperture circular, almost erect, peristome thickened, a tube behind the left margin of apei;turb just below point of insertion, generally short but rarely continuous across tho body- whorl towards the . Diam. maj. 4, alt. 5-75 mm. • JIab.—Sangir and Gilolo Is. In all the numerous specimens found on Gilolo I. tho tube is short; of the eight specimens found on Sangir I., three have the long tube extending over and above the body-whorl, and five have the tube short. The direction of the tube in those examples where it is short varies: in some tho tube turns upwards, in others it lies more or less at right angles to the spire.

18. ADELOHOEPHA DOIIEHTTI, n.sp. PI. XI, Kg. 19. Shell conoidal, perforate, dirty white, with fine close-set, almost vertical costte ; whorls 5£, very convex, regularly increasing; aperture subcireular, vertical; peristome thin, simple; operculum typical. Diam. maj. 2, alt. 2-5 mm. Hob.—Teniraber I. Much smaller than any other known species of the genus.

19. OirpnALOTEOPis (SELEXOJIPHALA) TEXCTS, n.sp. PL XI, Fig. 15. Shell perforate, globose, acuminate above, thin, semi-transparent, almost vertically striate; whorls 5J, very convex, last equal in height to two-thirds of whole shell; aperture D-shaped, somewhat oblique ; peristome thin, angled and slightly expanded at the base of the columella, the latter oblique. Diam. maj. 3, alt. 4 mm. Ilab.— Timor I. Allied to 0. Dohcrtyi, Aldrich, from Sumatra, but it is thinner, more openly umbilicated, and has more convex whorls.
