TERTIARY FAUNA OF FLORIDA 



1605 



North Carolina, seventy-one from the Pliocene of South Carolina, and thirty- 

 one from the Pliocene of North Carolina. Of species only known from the 

 Pliocene of Florida there are two hundred and fifty-six. 



The epoch of the Pliocene in Florida was one of tropical conditions. This 

 is indicated not only by the large number of species included in the fauna, but 

 by their character. With the fauna of the cool temperate Chesapeake epoch the 

 Caloosahatchie fauna has only thirty-two species in common, but with the warm 

 temperate climate of the Duplin epoch one hundred and fourteen. With the co- 

 temporary but cooler-water Waccamaw fauna there are only seventy-one links, 

 and with the later, more northern, and still cooler Croatan fauna these have 

 diminished to thirty-one. 



LIST OF FLORIDIAN PLIOCENE FOSSILS. 



Those marked C are from the outcrops on the Caloosahatchie ; S, those from Shell 



Creek ; A, those from Alligator Creek ; M, those from the Myakka River. Those 



marked W are also authentically known from the Pliocene of the Waccamaw beds of 



the Carolinas, and the asterisk denotes their persistence to the recent fauna of the coast.
