TERTIARY FAUNA OF FLORIDA 



Oligocene of St. Domingo and of the Bowden marl, Jamaica; Mio- 

 cene (?) of Cerros Island, off Lower California ; Post Pliocene of Lower Cali- 

 fornia. Recent in the Gulf of California at Acapulco and southward. 



This is one of the types which were exterminated on the east coast of 

 America by the disturbances which united the two continents and cut off 

 access to both oceans, and which survived to the present fauna on the western 

 side of the continent as united. It appears to be rare in the Oligocene, but 

 the type is much older and is represented in the Cretaceous by O. falcata 

 Morton.

Eocene of South Carolina ? 



Miocene of the Santee Canal, South Carolina, Ravenel ; and of the 

 Choptank River, Maryland, Burns and Harris. 



The original reference of this species to the Eocene is probably erro- 

 neous. The species, represented by some of the original Santee specimens 

 in the National Collection, has only been definitely recognized from the Lower 

 Miocene. 



It appears to be a sufficiently distinct species, nearly related to 0. tri- 

 gonalis.
