A delicate, slender shell, varying a good deal in size, and 

 closely allied to, if not the same as B. clavula, Quoy, B. bacteri- 

 onides, D'Orb., and B. octo?ioides, Adams, from the West Indies. 

 Perhaps it is a species attached to the plantain, cocoa-nut, or some 

 other wide-spread tropical plant.
