This was fent to us for a Briti/Ij flicll by a conchological 

 friend, who thinks it v/as taken on the fFe/ch coal! ; and as 

 we conclude he had good authority, though not perfonal, 

 we venture to infert it ; more efpecially as it appears to be 

 a nondelcrlpt. 



Shell ovate, of a pink colour fliaded to white at the fliorter Myx 

 end, and regularly ftriatcd concentrically : the beak is not Nitzns. 

 quite central, but moderately proniinent. a he infide is 

 fimilar in colour but not fo glofTy as the outfide ; the hinge 

 is furnifhed with a fingle tooth in one valve, which (huts 

 into a deep cleft between tv/o flight elevations m the other 

 valve. Lengfh nearly a quarter of an inch ; breadth not 

 quite three eighths.

 is more regul.iriv oval without bting attenuated at one end, 

 befidt'& differing iti the obvious diiiinction oi tho hinge.
