The Solen Erisis is a thin, brittle shell, prettily mottled, 

 on the outside, with brown and green. It is always 

 curved, and most so in young shells. The inside is 

 bluish white, and the hinge consists of a single tooth in 

 one valve, which is inserted between two others in the 

 opposite valve, with a prominent continuation, part of 

 the way down the cartilage in both valves. 



This species is found in the Mediterranean, and upon 

 the northern coasts. It is not a common species in 

 England, but is occasionally found upon our shores, 

 and particularly at Sandwich, where many specimens 

 have been collected at different times.
