This shell may be immediately distinguished from the 

 preceding species, by its truncated end, which is so per- 

 fect, that it appears as if pared down by art, till the 

 teeth are seen close to the end of the shell. There is 

 not the vestige of a margin, in any of the many spe- 

 cimens which the author has had an opportunity to 

 examine. The var. /3. is shorter than the other, and 

 somewhat tapering towards its rounded end. 



It is found in the American and Indian Seas, and 

 measures from three to seven inches, from end to end.

This is a very delicate shell, of a fine violet colour. 

 The teeth, of which there is one in each valve, slide upon 

 each other, when the shell is closed, the same as in the
