The changes in the description made by him upon the examination 

 of nine specimens from Lake Khanka, are chiefly verbal and quali- 

 fying, the most important being the "interorbital space a little nar- 

 rower than the upper eyelid," an observation which I can corroborate 

 from my own inspection of the same material in 1898. He also adds 

 that the male is provided with black nuptial excrescenses on the 

 thumb.
