along the body, the metatarsal tubercle reaches beyond the eye. Skin 
minutely granular above and beneath ; sides of head and body and 
upper 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 middie 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 choane. 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.
