Lieut. -Col. Godwin- Austen figures (pi. 46, tig. 2) a variety sent 

 to iiim by Col. Beddome from tiie Jeypur Hills, which has rather 

 more tumid whorls and is less acuminate than the type. In three 

 out of eight specimens he notices another point of difference, 

 i. e. the right margin of the peristome being sbarply sinuate, a 

 character not shown in the Golcondah Hill specimens.
