 Islands and Madeira.

This species has a very extended synonymy. Locard gives twenty- 

 three, but in a paper of this sort such an extension seems needless, the 

 shell being common enough and well-known. Its distribution is 

 general in the North Atlantic, from Great Britain to the Azores, 

 and throughout the Mediterranean. 



Station V. 109 fathoms. Two odd valves.
