This elegant shell seems to be described only by Da Costa ; he 

 says he was informed it had been fished up about Weymouth, in Dor- 

 setshire, but had only seen it from Cornwall. We have it from the 

 coast of Devonshire also, from which it appears an inhabitant of the 

 western coast in general, though it is very rarely met with.
