 Whorls 7 in number, convex, smooth ; columella very broad,

 which show somewhat obscurely through the substance of the shell 

 (Reeve). 



Habitat unknown. 



Bulimus cerussatus REEVE, Conch. Icon., pi. 74, f. 536, species 

 537 (August, 1849). 



Pfeiffer unites this to B. annulatus as a variety. If specifically the 

 same, cerussatus has priority.

 the lens showing close, decussating spiral lines; whitish, ornamented
