from JB. viridis but also from B. raddei, the Chinese representative 

 of B. calamita. 



The length of the head equals three fourths or four fifths 

 of its breadth ; the snout is short and blunt, the loreal regions 

 slightly concave, the canthus rostralis indistinct. The nostrils are 

 a Httle nearer the anterior angles of the eyes than the tip of the 

 snout ; and the space between them equals that between one of them 

 and the lip. The eyes are about equally distant from the tip of the 

 snout and the angles of the jaws. Tlie interorbital space is flat 

 and narrow, its breadth being equal to two thirds or four fifths 

 of the upper eyelid's greatest breadth. The tympanum is ratlier 

 indistinct, generally quite hidden in its posterior half, small and 

 rounded ; its diameter does not equal half the greatest diameter of 

 the orbit. Tiie cleft of the mouth extends hardly beyond the pos- 

 terior corners of the eyes. The tongue is elliptical, moderate ; its 

 length equals twice, or nearly twice, its breadth ; it is somewhat 

 broader in females than in males. The parotoids are small, ovate or 

 subtriangular ; they begin at a short distance from the upper eyelids, 

 and are slightly convergent backwards ; their breadth equals two 

 thirds or four fifths of their length, ^which equals the distance 

 between their anterior edge and the nostril or less. 



The body is about three times as long as the head in females, a 

 little less in males and young. 



The fore limb is always shorter than the body, especially in 

 females, which have it thinner than males. The fingers are short 

 and rather pointed ; the third is the longest ; when laid side by side 

 the first does not extend beyond the second, which is a little longer 

 than the fourth ; the thumb is hardly broader in males than in 

 females ; the subarticular tubercles are mostly two-rowed. There is 

 a large flat rounded tubercle in the middle of the hand, and another, 

 smaller and oval, at the base of the thumb. 



The hind limb is relatively very short ; a httle longer than head 

 and body in males, it is scarcely more, or even less, in females and 

 young ; if it is carried forwards against the body, the heel reaches to 

 the posterior corner of the eye in males, to the shoulder in females 

 and young. In these the tibia is scarcely longer than the head ; it is 

 rather longer in males ; its upperside is occupied by a large parotoid- 

 like gland, which, however, is sometimes rather indistinct. A cuta- 

 neous fold, generally very distinct, extends along more than half the 

 length of the inner margin of the tarsus. The metatarsus is provided 

 with two large tubercles, that at the base of the first toe oval and very 

 prominent, that at the base of the fourth toe round and flat. The 

 toes are depressed and short, especially in females, united at the base 

 by a very short web ; the fourth is one third longer than the third, 

 which is distinctly shorter than the fifth ; the subarticular tubercles 

 are not very prominent, rounded, and mostly in two rows. 



The warts which are spread on the back are not very prominent, 

 are flattish, and never exhibit any trace of spines ; the largest are di- 

 stinctly porous to the naked eye ; there are two or three very promi- 

 nent ones at each angle of the mouth. These warts are little deve-
