PLATE CXLII. 



A species of Mya admitted with some doubt as a British shell : it 

 is a kind acknowledged however as such, by collectors of English 

 Natural History in general ; and is said to have been undoubtedly 

 fished up in the deep waters between the Dogger-Bank and the 

 eastern coast of England. 



The Mya Glycymeris is the largest of its genus, and is an inha- 

 bitant of most parts of the European sea. In the Mediterranean, 

 and on the northern coasts of Spain, it is not uncommon : on the 

 coast of France it is also found sometimes.
