Genus COLPOCHELYS Garman. 



The Bastard Turtles. 



Colpochelys kempi Grarman. 



Hawksbill Turtle. Bastard Turtle. 



This species is very closely related to the loggerhead turtle, and 

 seems to have first been definitely noticed from our shores by Dr. 

 0. P. Hay. In an elaborate paper he points out the difference be- 

 tween it and the loggerhead. He says that "it seems doubtful 

 whether any of the external characters that have been mentioned by 

 Garman and Coker as distinguishing this species from the loggerhead 

 are applicable in all cases/' though it is very different osteologically. 

 He records a stuffed and dried specimen taken at Atlantic City and 

 now in the United States National Museum, and a skull found on 

 the coast of New Jersey, now in the American Museum of Natural 

 History in New York.
