 front and dilated behind the peristome. Aperture obovate, oblique ; 

 margins convergent, united by a thin callus on the parietal wall; 



peristome thin, slightly expanded and reflexed ; margins evenly 

 rounded, columellar margin triangularly dilated and impinging upon

Co-types in Colonel Beddome's and my collection. The new species 

 is allied to V. Ladacensis, but is more excentric than that species, and 

 the last whorl descends more deeply in front, the whorls are more 

 tumid, the body-whorl is more compressed, the suture deeper, and the 

 last quarter whorl is more dilated, while the umbilicus is more open 

 and the columellar margin more dilated.
