This species resembles the Bengal N. swbgesta, Bs., and the Cey- 
lonese N. carneola, Pir. (as figured by Reeve) in form, but has 
a duller histre and deeper sutures, resembling in the latter character 
some of the Ceylon Nanine of the same section. The microscopic 
sculpture is peculiar, the impressed lines being very close, but some- 
what irregular and wavy. They cause the dull. appearance of the 
surface. An ordinary lens is insufficient to shew them: under a 
microscope with a 14 in. objective they are wery distinct.

Shell. obtectly perforate, rather depressly turbinate, very thin, ful- 
vous, horny, dull, obliquely striated and marked with very fine and 
close impressed lines, also oblique, only visible under the microscope, 
polished beneath. Spire conical, apex acute, suture impressed. 
Whorls 53, convex, gradually increasing, the last much broader, obso- 
letely sub-angulate at the periphery, tumid beneath. Aperture nearly 
vertical, roundly Innate, breadth very little exceeding the height. 
Peristome thin, straight, margins sub-distant, columella nearly vertical 
and very briefly reflexed above, almost concealing the perforation.
