Judging from the above synonymy one might suppose that the 

 Japanese Clemmys is a ])articularly close ally to one or both of the 

 west-pale arctic species, since it has been described as a variety of 

 Emys vulgaris by Temminck and Schlegel, and as a variet}" of E. 

 caspica by Dumeril. This is not so, however, and the only character 

 which points in that direction is the short anal seam, a character 



a From KXe/i/ivi, turtle. b Figs. 2-3 reproduced in this work on Plate XXIX.
