Head large ; snout obtuse ; superciliary ridges greatly elevated and 

 terminating posteriorly in a knob 5 upper jaw emargiuate, lower fur- 

 nished with a hook in front; parotoid large, reniform, and reaching from 

 below the tympanum to near the shoulder; tympanum large; vocal 

 vesicle internal; body above warty, beneath granulated. 



The head is large, and without warts, except a few small ones on the 

 eyelids, and the mouth is large. The snout is obtuse, and from its tip 

 runs an elevated bony crest, subdividing at the nostrils, and forming the 

 superciliary ridges. These diverge and increase in elevation as they 

 reach the posterior part of the orbit, where they terminate in a rounded 

 knob or tubercle. Their greatest height gives to the upper surface of 

 the head a canaliculated appearance; a second or postorbital ridge de- 

 scends from each of these and completes the posterior border of the 

 orbit. In consequence of the divergence of the superciliary ridges the 

 postorbitals are short. There is always present a short but distinct 

 ridge above the tympanum at right angles to the postorbital— the supra- 

 tympanic. The upper jaw is deeply emarginate in front ; the lower is 

 furnished at its anterior xjart with a distinct hook, which is received in 

 the notch of the upper jaw. 



The nostrils are small and round, placed near the point of the snout. 

 The eyes are large, prominent, and very beautiful; the pupil is black, 

 the iris reticulated with gold and black, and has an inner margin of 

 yellow. The tympanum is large and dusky, with a minute spot of 

 a lighter shade in the center. The parotoid glands are large and 

 reniform. 



The back and sides are dusky, aud covered with warts of different 

 sizes; a pale vertebral line extends from the head to the vent, on each 

 side of which are found the largest warts; an irregular row of spots of 

 yellowish-white exists on the flank, having somewhat the appearance 

 of an indistinct band, extending from the inferior and posterior part of 

 the parotoid gland to within a short distance of the thighs. The whole 

 inferior surface of the animal is dirty white, with a strong tinge of 

 yellow. 



The anterior extremities have the upper surface dusky, with blotches 

 and bars of dark brown; the lower surface dirty white, tinged with yel- 

 low. The posterior extremities are dusky brown above, marked with 

 blotches and transverse bars of darker brown, and dingy white beneath. 



This species attains to the same size as the typical form of B. J. amer- 

 icanus. A specimen (4501) from Florida exhibits remarkably elevated
