Description.-The head is about one fourth broader than long; the snout is short and blunt, the canthus rostralis scarcely distinct. The 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 eyes 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 concave 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 the 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.
