Hab. Jamaica; Adams. 



The waved pattern of the numerous brown lines with 

 whieli tliis shell is spirally painted, is occasioned by the 

 intrusion, on the surface, of the lines of growth. The 

 species is allied to //. lima, but is characterized by the 

 same peculiar lateral compression as in //. Themles of the 

 Philippine Islands.
