Description. — The head is about one fourth broader than long ; 

 the snout is short and blunt, the canthus rostralis scarcely distinct. 

 Tlie nostrils are equally distant from the anterior angles of the eyes 

 and the tip of the snout, or somewhat nearer the former ; the space 

 between them equals that between one of them and the lip. The 

 eves are nearer the tip of the snout than to the angles of the jaws. 

 The interorbital space is flat, in some very old specimens slightly con- 

 cave and broad, its least breadth being somewhat more than the 

 upper eyelid's greatest breadth. The tympanum is generally hidden, 

 except its front edge ; it is distinct in most Japanese and some Chinese 

 specimens ; it is rounded ; and its diameter equals hardly half that of 

 the orbit. The cleft of the mouth extends much beyond the level 

 of the posterior angles of the eyes. The tongue is elliptical, moderate, 

 once and a half to twice as long as broad ; it is generally broader in 

 females than in males. The parotoids are elliptic, twice or twice and 

 a half as long as broad in European and Japanese specimens, shorter 

 and oval in tlie Chinese ; they are very prominent, and their inner 

 edges diverge backwards. 



The body is from twice to nearly three times as long as the head. 



The fore limb is as long as or slightly shorter than the body and 

 very stout in the male, shorter and thinner in the female. The 

 fingers are rather short and more or less pointed ; the third is the 

 longest ; the second and fourth are equal and scarcely shorter than 

 the first ; the subarticular tubercles are two-rowed. There are two
