" Shell subpellucid, somewhat gloss} r , with seven ventricose and verv 

 deeply divided volutions, tapering to rather an obtuse apex ; the first or 

 body-whorl is much inflated ; a white band runs spirally from the base to the 

 apex, giving it a strong appearance of being carinated, and the volutions are 

 slightly wrinkled across. It is furnished with a deep and wide umbilicus, 

 which, viewed directly from the base, is partly hid by the reflected lip of the 

 shell ; aperture subrotund, lip very thin, and reflected on the columella. The 

 colour is of a dirty white, with several interrupted dark umber-coloured 

 bands, which run spirally from the base to the apex ; length fths of an inch ; 

 breadth 3ieighths," Brown. — This is probably only a monstrous variety of some 

 of the more common species.
