head including the eyelids and the tympanitic region^ 

 covered with small, irregular ? granular tubercles. Snout 

 considerably pointed, with its extremity prominent and 

 perpendicularly truncated, and very slightly overreaching 

 the cleft of the mouth. Canthus rostralis obtuse, loreal 

 region concave, with a smooth groove running through it 

 from the lower part of the orbit to the nostril. Occiput 

 deeply concave. Nostril slightly below the extreme end of 

 the canthus rostralis and the snout. Eye of moderate size, 

 prominent, but concealed from above by the eyelid. Tym- 

 panum distinct, one half as large as the eye, A linear fold 

 runs from the hinder edge of the orbit over the tympanum 

 towards the armpit, Cieft of the mouth twice as broad as 

 long ; tongue not large, broadly but not deeply notched 

 behind, attached to the gullet nearly its whole length. 

 There is a toothed prominence on each side of the vomer, 

 a little lower than the openings of the nostrils, and running 

 in a straight line across the jaw. Vomerine teeth on long 

 ridges gradually rising from the inner angle of the choanal , 

 running back and convergent behind, terminating in toothed 

 prominences. Skin of the back, belly, throat, legs and 

 inside of fore limbs smooth. The whole of the upper part 

 of the head including the eyelids, the front of the fore limbs, 

 and a remarkable cutaneous expansion on the side of the 

 trunk between the fore and hind limbs covered with granular- 

 like tubercles, with a few smaller ones on the tympanum. 

 The smooth portion of the skin of the back is separated 

 from the rough head by a somewhat elevated ridge, caused 

 by a depression of the head, and running in a line across 

 just behind the orbits, and continued into the linear fold 

 behind the tympanum, a good deal like that in the adult
