" This species is only found on the Cornish coast, and even is very- 

 scarce there, beinp- most generally dredged some miles from the shore j 

 for the Shell is so thin, that it will hardly bear rolling from its native 

 spot to the beach. It is generally found affixed to a species of escal- 

 lops, called frills, in Cornwall." Da Costa.
