 dead shell from the Crouch river near Burnham, and living 

 specimens have since been found there. We have in the 

 Museum two valves sent, with other things, by a dredgerman 

 from the same locality. And Mr. J. E. Cooper and Mr. A. S. 

 Kennard have since presented to the Museum a set of Kentish 

 specimens, together with some notes, from which a portion of
