Upper view of head. 
Head regularly triangular, the angles of the maxillaries forming 
a more or less prominent point on each side; crown on each side 
with an enormous, erect, sharp bony ridge from the orbit to the 
parotoid, in the adult; this ridge scarcely developed in the young; 
a more or less distinct parietal ridge; snout prominent, pointed ; 
interorbital space much broader than the upper eyelid; tympanum 
more or less distinct, about two thirds the width of the eye. First 
finger not extending beyond second ; toes half or two-thirds webbed, 
with simple subarticular tubercles; two moderate metatarsal tuber- 
eles; no tarsal fold. The hind limb being carried forwards along 
the body, the tarso-metatarsal articulation reaches the eye or a little 
beyond. Skin covered with small warts; parotoids rather small, 
subtriangular, oblique; a lateral fold formed by a series of large 
conical warts. Brown above, with a few black spots; frequently a 
light vertebral line; beneath immaculate or spotted. Male with a
