Original description : — " Shell dextral, small, tumidly fusiform ; 

 sculpture, the two apical whorls smooth, two next with fine close 

 ribbing, the last three whorls smooth or glassy ; colour pale 

 ochraceous white ; spire, sides rather flat, apex moderately blunt ; 

 suture slightly impressed ; whorls 7^, the antepenultimate the 

 largest and tumid ; constriction on the side, well behind the 

 aperture, at about 1 miilim. distant; aperture oval, vortical; 

 peristome double ; columellar tooth large in front, and dii'ected 

 downwai'ds. 



" Major diam. 1-8 ; alt. axis 3-5 miilim." 



I/ab. Burma: south of Barak, Munipur (&'ocZ((;Hi-^usto?,). 



" A larger shell, with rather a different shaped spire 4 miilim. 

 iu height, was found at Asalu, with tiie constriction in the same 

 position. 



" It is an allied form of D. jatinf/ana, from the North Cachar 

 Hills, which is a larger, more tumid species with the constriction 

 farther behind the aperture. 



" A single specimen, only 3 miilim. in height, was sorted out of 

 the box containing D. chennelli, from the Lhota-Naga Hills,"
