The Asiatic loggerhead turtle is easily distinguished from the other 

 marine turtles of the Far East b}" having more than four pairs of costal 

 shields. Like the hawksbill it has two pairs of prefrontals, but the 

 shields on the carapace are not imbricate. The figure of the young 

 Atlantic loggerhead will help placing any specimen of the group in 

 the proper genus, but it should be remembered that the vertebral 

 and costal shields in C. olivacea are apt to be more numerous. No 



a The name Caret (new Latin Caretta) according to Lacepede is the one by which the 

 hawksbill turtle is generally known in the country it inhal>its. Carey is Spanish for 

 tortoise shell.
