INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 681 



Florida (Conrad) ; Texas (Reamer) ; Cuba (D'Orbigny). Fossil in 

 the Post-Pliocene of Virginia, South Carolina, and Florida ; and : 

 in the Pliocene of South Carolina. A similar form, if not identical 

 (P. Caroliiiensis Conrad), occurs in the Miocene of South Carolina. 



A species scarcely to be distinguished from this was sent to me in 

 large numbers from La Paz, Gulf of California, by Captain Pedersen.
