Vomerine teeth in two transverse series, between the wide choane. Snout broad, 
not depressed, with distinct canthus, and sloping concave sides. Distance of the 
nostril from the eye equal to the diameter of the latter. Interorbital space broader 
than the upper eyelid. Tympanum distinct, two-thirds the area of the eye. The 
three outer fingers are one-third webbed, and provided with disks which are equal to 
those of the toes, but smaller than the tympanum. Toes fully webbed, with subarti- 
cular tubercles ; a very distinct tarsal fold; no external rudiment of pollex. Upper 
parts smooth ; a slight fold over the tympanum ; no fold above the vent; no appendage 
at the heel; a fold across the chest. Abdomen granular ; throat and chest smooth. 
Brownish, with darker subsymmetrical markings on the back and crown of the head, 
upper lip and limbs with dark cross-bands ; a subtriangular lighter (in young specimens 
white) spot below the eye, and a narrow blackish stripe along the fold behind the 
tympanum. A very common variety is green or greyish-olive above, sometimes with 
rounded black spots; a deep black band starts from the eye, covers the tympanum, 
and is lost behind the shoulder ; it is bordered below by a white line which fringes the 
upper lip; the limbs are cross-barred in this as in the other variety, but not the upper 
lip. Lower parts whitish, very rarely with black spots. Male with an external vocal 
sac on each side of the throat.
