We are indebted to Pennant for our knowledge of 

 this fragile and transparent shell. He found it at Red 

 Wharf, in Anglesey, and describes it as a somewhat 

 arched and oval shell, with a hinge consisting of a sharp 

 double tooth on one side, receiving a single one from 

 the opposite, with a process in each valve, pointing 

 towards the cartilage of the hinge. It is a very tender 

 shell, covered with a shining epidermis, of a light 

 greenish brown colour. It seldom measures more than 

 an inch from end to end. 



Mr. Montagu found this shell in Cornwall, and some 

 specimens have been obtained, but very rarely from 

 Sandwich. The few that occur on the Sandwich shore, 

 have been found at low water, in the mud, near the 

 mouth of the haven.
