Orhjinid description: — "Shell dextral, ovately fusiform, 

 moderately thick, pale horny. 8cul|iture very tine, almost 

 disappearing on the last two whorls. Sides of; spire moderately 

 flat. Whorls 7, penultimate and antepenultimate the largest, the 

 last ascending slightly. Constriction in middle of aperture, 

 which is circular and vertical; columellar margin rounded, tooth 

 moderate. Peristome simple, double, rather strongly formed, the 

 inner lip continuous. 



" Alt, 0-15 [3-75 mm.], diam. 0-70 inch [? 0-07 inch= 1-75 ram.]. 



" This shell is very similar in form to D. austeni, W. Blf., from 

 the Khasi Hills, but it is much larger, that shell only being 0-90 

 [? 0-09] inch in length, and the two last whorls are not so smooth 

 and show slight traces of sculpture.'' (Godwin- Austen, L876.) 



" Comparing this more closely with the form from the Khasi 

 Hills, it differs very much in its general shape, being much 

 smaller below, the antepenultimate being much larger in pro- 

 portion to the penultimate; the apex is more attenuate, and the 

 sculpture differs. It must therefore be distinguished as a 

 species." [Godwin- Austen , 18S6.)
