Show 444 LIEUT.-COL. BEDDOME ON NEW LAND-SHELLS. [Julie J, last whorl suddenly ascending and touching the antepenultimate, inconspicuously keeled at its base ; aperture oblique, subcircular, white within ; peristome continuous, single, black externally, slightly reflexed and expanded : total length \ inch. Ceylon, near the summit of Pedrotalle Galle, the highest mountain in the island, rare. DIPLOMMATINA (NICIDA) CEYLANICA, n. sp. ( Plate LII. fig. 9.) Shell not rimate, subcylindrico-ovate, thin, smooth, white, rather shining; whorls 7, convex, the antepenultimate the largest, the four upper ones gradually decreasing, the last whorl ascending slightly on the penultimate, keeled rather conspicuously at its base; aperture vertical, oblique; peristome continuous, single, scarcely expanded : total length A inch. Ceylon; on Pedrotalle Galle, about halfway up from Newera Ellya, abundant. These two latter were the first species of this genus detected in Ceylon ; and at the same time (1870) I found two other species about Rambaddi, at a much lower elevation-one the common Indian N. liricincta, and the other a species allied to m y N. anamallayana, and which I refrain from describing here as I have since received it from Mr. Neville under the name of N. chrysalidea (Neville), and do not know whether he has already described it or intends doing so. That gentleman has also forwarded me a single specimen of a very slender distinct species under the name of N. depauperata; and more will, no doubt, be discovered in Ceylon and the western chain of ghats in the Madras Presidency. OPISTHOSTOMA DECCANENSE, n. sp. (Plate LII. figs. 10 and 11.) Shell irregularly rhomboidal, pale pink, with an oblique rather distant costulation, prominent on the lowest whorl, but less so on the others; whorls 5, excentric, the two apical ones very small aud depressed, and only visible as a single small speck from a side view, the third much larger, cou vex, the fourth, or penultimate, convex, very large, and much dilated, lowest whorl constricted as usual aud in front of the constriction deflected inwards, but not concealing the umbilicus; aperture reversed, circular, quite vertical and parallel with the penultimate whorl; peristome touching the centre of the penultimate whorl, double, both lips slightly dilated, with a broad channel between them : total length -^ inch, breadth T T inch. A smaller shell than O.fairbanki (Blanf), and the costulation less prominent; the two apical whorls are much more depressed, the penultimate whorl is much larger, the deflection in front of the constriction is less sharp, and not, or only partially concealing the umbilicus; the peristome is more completely double, with a wide space between the two lips; and the aperture is quite circular. Nallay-Mallay hills, Kurnool district, common on the Yerra Chalma, about 3000 feet elevation. 1 have also a single specimen collected on the Sivagherry hills, Tinnevelly district. |
