 Conch. 61. t. xvi. f. 63,— Near Dublin. Mr Stephens. 

 " Shell subpellucid, somewhat gloss}', with seven ventricose and very 

 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 |ths of an inch; 

 breadth 3|eighths,"Brown — This is probably only a monstrous variety of some 

 of the more common species. 



b. Without a pillar-cavity. Globose. 



75. H. aspersa. — Shell brown, with white transverse stripes ; 

 mouth subascendino:
