444 LIEUT.-COL, BEDDOME ON NEW LAND-SHELLS. [June |, 
last whorl suddeuly ascending a:d 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. 
Dretommatrina (Nicrpa) 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 +!) inch. 
Ceylon; on Pedrotalie 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 my N. anamal- 
layana, 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 J. 
depauperata ; and more will, no doubt, be discovered in Ceylon and 
the western chain of ghats in the Madras Presidency. 
OpiIsTHOSTOMA DECCANENSE, b. 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 and 
depressed, and only visible as a single small speck from a side view, 
the third much larger, convex, the fourth, or penultimate, convex, 
very large, and much dilated, lowest whorl coustricted as usual and 
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 5 inch, breadth +; 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 con- 
striction 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 1s 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.
