Description. — This species is closely allied to the tw^o preceding 

 ones, but all the thi'ee may be easily chstinguishcd from one another 

 by the characters given above. As in the two other species, each 

 canthus rostralis represents an arch, with the convexity bent inwards ; 

 the loreal region beneath is slightly grooved, so as to give to the 

 muzzle a pointed appearance ; it is vertically truncated in front, being 

 rounded in B. gutturosus, and obUquely tmncated with prominent 

 upper part in B. granulosus. The crown is broad, rendered shghtly 

 concave by a bony enlargement nmning round the upper edge of the 

 eye, and swollen into a prominent ridge above the tympanum ; in young 

 indi-viduals another branch arises from behind the eye and is lost in 

 front of the paratoid. The tympanum is very distinct, and at least 

 one-half the size of the eye. The paratoid, being in young specimens 

 more rounded and prominent, becomes subtriangadar in old age. All 

 the tipper and lower parts are thickly covered with smaU spiae- 

 bearing warts ; sometimes a series of rather larger ones may be 

 distiaguished running from behind the paratoid to the loin. The 

 second and fourth fingers are nearly of the same length, the third 

 much longer. The inner edge of the metatarsus is covered with spiny
