Posterior half of the abdomen granular. No fold across chest. Habit moderate. 
Head not wider than the trunk; snout somewhat acuminate, with distinct canthus 
rostralis and with the sides subvertical. Tympanum about half the area of the eye 
(in both sexes). Vomerine teeth in two short groups, well separated from each other, 
behind the level of the choane. Skin of the upper parts smooth, either entirely 
or with several exceedingly fine linear folds—one from the eye above the tympanum 
to the shoulder, another oblique from the eye towards the centre of the back, and one 
or two on each side of the hinder half of the back. Disks of the fingers and toes 
very small; first finger a little longer than the second. Two small metatarsal 
tubercles ; series of subarticular tubercles continued on the metatarsals; no tarsal 
fold. The length of the body is almost equal to the distance between vent and 
heel. Greyish-olive; hind limbs obscurely cross-banded; an indistinct dark band 
between the eyes. A black band runs from the nostril through the eye above and 
round the tympanum; vent black; generally one single small black spot or a pair in 
the centre of the back ; lower parts white. 
A small species.
