This shell, of which I have only seen immature specimens, is 

 described by Nevill as being smaller than chloroplax, with more 

 closely wound whorls, higher spire, less acute keel, and more 

 convex base. The form of chloroplax with which the comparison 

 was made was probably that from Murree, and, as already pointed 

 out, it is uncertain whether that form is identical with the Simla 

 type.

" Shell small, depressed, thin, horny brown, with the suture 

 distinct, roughly, regularly, and closely ribbed above ; sculpture 

 of a similar kind, but almost obsolete, can be traced on the base ; 

 whorls 7, closely wound, the last scarcely, if at all, broader than 

 the previous one, more or less subangulate at the periphery ; 

 base convex, distinctly excavated round a deep narrow umbilicus 

 (? perforation) ; aperture very shallow, the outer margin distinctly 

 thickened, slightly subangulate in the middle ; columella very 

 slightly reflected, oblique, evenly rounded, without any angulation 

 at the base, in this character resembling N. splendens and differing 

 from N. prona. I know of no Indian species like this inter- 

 esting little shell ; in shape it somewhat resembles the smooth 

 N. woodiana. 



" Diain. 11 J, alt. 5|, axis 4J, apert. lat. 5J mm." (Nevill.)

Dr. Stoliczka noted the presence of a mucous pore.

*258. Khasiella ? tandianensis, Theobald (Trochomorpha), J. A. S. B. 

 1881, p. 46. 



" Shell trochiform, keeled, narrowly umbilicated, thin, horny* 

 "Whorls 6, slowly increasing, coarsely striated transversely. Aper- 

 ture but slightly oblique, quadrately lunate. Margin (of peristome) 

 simple, near the columellar briefly reflected. 



"Major diam. 9-6, height 6'7 mm." (Theobald, in Latin.) 



Hob. Near Tandiani, Hazara, in woods, at an elevation of 

 8500 feet. 



"The animal has a distinct overhanging lobe to the mucus- 

 pore. The nearest ally of the shell is perhaps T. hyba, Bs., which 

 is found from Chamba to Kashmir."
