A neat small species, like P. patagonicus, King, in 

 miniature. A large dead valve, somewhat ciiaracterless, 

 found on the N.W. Falkland coast after a storm, probably 

 belongs to this latter species {patagonicus).

Accompanying this a bottle was forwarded, containing a

 C. falldandicam or its very near congener iridcscens, Cooper 

 and Preston.
