along the body, the metatarsal tubercle reaches beyond the eye. Skin 

 minutely granular above and beneath ; sides of head and body and 

 Tipper surface of limbs with triangular skinny appendages. A very 

 prominent dermal ridge unites the horns across the interorbital 

 space ; two others begin on the upper eyelid, approach each other on 

 the middle of the back, diverge again, and finally unite into a point 

 above the vent. Greyish above, with symmetrical brown markings ; 

 limbs cross-barred; throat brown. Male with a subgular vocal sac.

Vomerine teeth in two small groups between the choan^. Head 

 large, not bony ; nostril equally distant from the eye and the tip of 

 the snout, or a little nearer the former ; upper eyelid produced into 

 a horn-like appendage, the length of which equals at least three 

 fourths of the diameter of the eye ; interorbital space concave ; tym- 

 panum hidden. First finger scarcely longer than second ; toes 

 webbed at the base ; subarticular tubercles much developed ; inner 

 metatarsal tubercle oval, blunt; no tarsal fold. The hind limb 

 being carried forwards along the body, the metatarsal tubercle 

 reaches the eye. Skin granular above and beneath ; the sides and 

 upper surface of the limbs intermixed with large conical tuber- 

 cles ; a dermal ridge, formed of large granules, unites the tips 

 of the horns across the interorbital space ; two others begin on the 

 -upper eyelids, approach on the middle of the back, diverge again, and 

 finally unite in a point above the vent. Brownish above ; a large 

 spot below the eye, a festooned band bordering the dorsal ridges, 

 and cross bars on the limbs dark brown ; a spot on each side of the 

 snout, and the middle of the back between the ridges, sometimes 

 whitish.
