[2] Physical Structure: Upper head-scales smooth or feebly keeled, imbricate, scarcely enlarged on supraorbital region; a few small spines on each side of the head above the tympanum; latter measuring at least half the diameter of the orbit.

Dorso-nuchal crest well developed in the male, composed of falciform spines directed backwards, the longest measuring the diameter of the orbit; it gradually decreases in height on the back, being reduced to a mere denticulation on the sacrum.

The adpressed hind limb reaches the tympanum or the posterior border of the orbit; fourth finger slightly longer than the third.
