It may not be out of place to mention, in this connection, that I have in my 

 cabinet, from the Eocene of South Carolina, teeth of Crocodilus macrorhynchus, 

 Harlan, and of two nondescript saurians ; also from the Pliocene of Darlington, 

 South Carolina, (lying on the Cretaceous,) teeth of Crocodilus davirostris, Morton, 

 and from the Pliocene of Edisto, South Carolina, a new species of Crocodilus. I

 which will be made the subject of a future communication.
