HERPETOLOGY OF JAPAN. 497 



This leaves only the species G. hamiltonii and G. reevesii in the 

 genus Geoclemys, and both being strictly congeneric it matters not 

 which one we select as the type. It is, consequently, quite irrelevant 

 that Gray himself in 1869 " included these in his new genus Damonia. 

 As the latter only includes species congeneric with G. hamiltonii and 

 reevesii, it becomes a synonym of Gray's Geoclemys of 1855. His 

 Geoclem^mys of 1869, as he then spelt it, on the other hand becomes 

 a synonym of Glemmys.
