Ostrea Georgiana, Fig. 896, was originally described from Shell Bluff, Ga., of Lower 

 Claiborne horizon. It is doubted whether it is rightly made a Vicksburg species. 



A specimen containing Eocene fossils has been reported by Upham and Crosby from 

 the drift of Cape Cod.

MIOCENE. 



1. CHATTAHOOCHEE. — Orthaulax puguax Heilprin, Pyrazisinus campanulatus Heilp., 

 P.acutus Heilp., Cerithium Hillsboroense Heilp., Potamides transsectus Dsdl, Vasum sub- 

 capitellum Heilp., Coralliophila magna Dall, Ampullina solidula Dall, Turritella Tampoe
