Description. — This species is closely allied to the two preceding 

 ones, but all the three may be easily distinguished from one another 

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

 canthus rostralis represents an arch, with the convexity bent inw^ards ; 

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

 muzzle a j^winted apiDearance ; it is vertically truncated in front, being 

 rounded in B. gutturosiis, and obliquely truncated with prominent 

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

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

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

 individuals 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 subtriangular in old age. All 

 the upper and lower parts are thickly covered wdth small spine- 

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

 distinguished i-unning from behind the paratoid to the loin. The 

 second and fourth fingers ai'e nearly of the same length, the third 

 much longer. The ianer edge of the metatarsus is covered wdth spiny
