This species is found, of a large size, in the Mediterranean sea ; 

 those which inhabit the English coast, as Falmouth and Cornwall, 

 rarely exceed the size of the smallest specimen we have represented 

 It is found likewise on the shores of Guernsey, and the coast of Ire- 

 land, where it is called the clog's cockle.
