The only specimens I have seen were collected in Florida, by- 

 Mr. Bartlett, more than ten years ago. It is a well known and 

 very common shell in the West Indies. Referred also to Mexico 

 by Pfeiffor. 



Mr. Thomson sent me specimens from New Bedford, where 

 they were probably introduced by the schooners of the live-oak 

 trade running to Florida. 



Animal (see T. M. V. S. lY, pl. 75, fig. 21) about the length 

 of the shell ; tentacles short, pointed, eyes at their interior base ; 

 proboscis extending beyond the head, bilobate, bluntly terminat- 

 ing ; posterior termination of the foot short, bifid, color dark- 

 brown.
