"This species may be known by its very large antepenultimate 

 whorl ami the curved axis of the spire, and its strongly developed 

 peristome and smooth low er whorls. It formed part of a collection 

 of shells made by Mr. AV. Kobert, of the Kiuisi Hills Survey 

 Party, in the Garo Hills, during the military expedition into them 

 in 1872-'3. Ten specimens were found." {Godtuin-Austcn.)

Orhjinal descnptioa: — "Shell sinistral, ovately fusiform; 

 sculpture, very distant fine costulation, 9 ribs on tlie antepenulti- 

 mate whorl when viewed from the front ; colour very pale 

 greenish ; spire low, sides rounded, apex ijlunt ; suture very 

 impressed ; whorls 4|, very swollen, sides very convex, penulti- 

 mate much the largest ; constriction on penultimate in centre 

 above the aperture; aperture oval, subvertical ; peristome double, 

 strong ; columellar tooth small, internal.

" The nearest ally of this species is D. jaintiaca, G.-A. ; it 

 differs, however, mmli in form, particularly in the expanded 

 penultimate whorl and in its very distant sculpture. A very large 

 number of it were collected in the above-named locality, and a 

 single example at Prowi in the Lahupa-JN'aga country. 



" In the collection sent me by Mr. Aldrich in a box marked 

 Naga Hills were about 40 specimens of this shell. The exact 

 locality was not recorded, but I take it they were from some part 

 of the Anghami-Naga Hills." {Godwin- Austen.)
