This is allied to the Nilgiri G. Jerdoni, Bens., but the sides of 

 the spire are less convex, the shell being more regularly pyramidal 

 with a less obtuse apex. 



In some of the specimens of this species collected alive, but in 

 which the animal had subsequently dried up, I found young shells. 

 It would thus appear to be viviparous. 



I have observed the same circumstance (the occurrence of young 

 shells inside the old one) in G. Cassiaca, B s. In other species of 

 this genus I have found small round eggs with a calcareous shell, 

 but these may be hatched, before they are deposited by the parent.

No described Indian species of Glessula possess sculpture at all 

 resembling that of the present small form. Under an ordinary lens 

 the shell appears to have a plicate striation, but beneath a stronger 

 power the strire are seen to be regularly nodose, and the decussating 

 lines become distinctly visible. The markings are very elegant and 

 regular, almost resembling those on some West Indian forms of 

 Cyclostomidce, as Choanopoma.
