I have specimens of the latter from many different places, they are all 
easily distinguished from JV. intwmescens. 
3. N. (Hemiplecta?) Stsparica, n.s. 
Shell openly perforated, subumbilicated, depressed, rather thin, 
striated, white with a yellowish brown epidermis, having a rather dull 
oily lustre. Spire convex, apex obtuse, suture flat, linear, submargi- 
nate. Whorls 4, very flatly convex above, apical whorl marked with 
very fine decussated plicate striation, the last not descending distinctly, 
but bluntly angulate above the periphery, convex beneath. Aperture 
oblique, semiovally lunate, white and pearly within, the breadth ex- 
ceeding the height, peristome thin, margins distant, united by a thin 
callus, columellar margin very oblique, and triangularly reflexed ciose 
to the perforation.

Habitat. Sispara ghat, Nilgiri hills, 8. India, rare. 
T know of no near Indian ally of this species. NN. Ovobia, Benson, 
from Darjeeling, which approaches it in some respects, is more globose 
and more solid, and has impressed sutures. The Ceylonese NV. Chenwz, 
however, closely resembles the species above described in form, though 
it is easily distinguished by its peculiar impressed sculpture. I ob- 
tained but two specimens, one of which was living, near the top of 
Sispara ghat. It is remarkable that so fine a shell should have escap- 
ed detection before. 
The animal differs in no essential character from those of the sinis- 
trorse Ariophanta section. It has a large mucus pore at the end of 
the foot without any lobe above, the mantle is oi moderate size, the 
head and neck granulated, the caudal portion of the body marked by 
oblique parallel, impressed wrinkles, and broadly margined near the 
sole with a double, impressed line. 
4. N. Macrochlamys ?) Hususcens, n. s. 
Shell scarcely perforate, inwardly depressed, yellowish or fulvous, 
thin, horny, dull, marked with very close microscopic impressed
