This kind is found in great abundance on many of our shores, as 

 Kent, Essex, Sussex, Devonshire, &c. and is also met with at Scar- 

 borough. 



When these shells are fresh and perfect, says Da Costa, the outside 

 is of an olive green, with some few transverse wrinkles ; but when 

 rubbed or worn are quite white, and almost smooth. The inside is 

 of a fine silvery colour.
