Inhabits the American Seas, about the Antilles. Lamarck. 

 Coasts of Jamaica. Solander. 



Shell about half an inch long, of a violet colour, and is more 

 nearly cylindrical, and has the extremities much less beaked 

 than B. birostris ; pillar straightish, and nearly entire.

 the outer lip thin at the margin; pillar twisted.

 Inhabits the coast at Weymouth. Pennant. Coast of Devon. 



Montagu. 

 This rare species is an inch long, and half an inch broad, and 

 is very smooth, white, pellucid, and brittle. It resembles B. 

 birostris, but differs in having the aperture much wider, and 

 the margin of the lip not thickened. 



spelta. 9. Shell oblong, equal and rather obtuse 

 at the ends ; lip arched, and its margin 

 thickened within.

 Inhabits the Mediterranean. Linnccus. Coasts of Naples. 



Ulysses. 

 Shell about three quarters of an inch long, and rather less than 



half as broad, white and rounded at both ends. This is a 



doubtful species, and it appears to me probable that all the 



figures above referred to may be young shells of B. gibbosa 



in different stages of its growth. 



verrucosa. 10. Shell ovate, transversely angular, 

 with a tubercle at each end.
