oblique lines above, more polished and radiately striated below. Spire 

 low, apex rather acute, prominent, sub -acuminate, suture deep. 

 Whorls 5J, rounded, the first narrow, the last much broader, very 

 bluntly sub-angulate at the periphery, and tumid beneath. Mouth 

 large, nearly vertical, lunately sub-ovate, breadth exceeding the 

 height ; peristome thin, straight, margins sub-distant, united by a very 

 thin callus, columellar margin nearly vertical above, very briefly and 

 broadly reftexed, nearly covering the perforation.

This species resembles the Bengal N. subgesta, Bs., and the Cey- 

 lonese N. carneola, Pl'r. (as figured by Reeve) in form, but has 

 a duller lustre and deeper sutures, resembling in the latter character 

 some of the Ceylon Nanince 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 1J in. objective they .are very distinct. 



5. N. (MacrochJamys ?) Lixa, n. s. 



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 5J, convex, gradually increasing, the last much broader, obso- 

 letely sub-angulate at the periphery, tumid beneath. Aperture nearly 

 vertical, roundly lunate, breadth very little exceeding the height. 

 Peristome thin, straight, margins sub-distant, columella nearly vertical 

 and very briefly reflexed above, almost concealing the perforation.
