slightly convex on the body, it passes gradually into the short con- 

 cave pillar, at the base of which there is only the faintest trace of a 

 tooth ; its edge is sliarp and patulous, with a minute chink behind 

 it. Alt. 0"18 in.; diaru. 0*1. Penultimate whorl, height 0*06.

This species slightly resembles Ada'on pusillus (Forbes), from the 

 Mediterranean and North Atlantic ; but the spirals in that species 

 are stronger, and are pit marked ; the suture is much stronger and 

 more channelled, and the body whorl is more barrel-shaped.
