Head moderately large, with distinct canthus rostralis, above with 

 equal sharply keeled scales ; nostril nearly equally distant from the 

 eye and tip of the snout ; tympanum rather large. A slight oblique 

 fold on each side of the neck, but no transverse gular fold. Dorsal 

 scales strongly keeled, the keels forming regular straight longitudinal 

 series, uniform or more usually with longitudinal series of enlarged 

 ones forming ridges along the back ; gular and ventral scales strongly 

 keeled. Limbs and digits rather elongate ; the adpressed hind limb 

 reaches the tympanum or the eye. Tail twice to twice and two 

 thirds the length of head and body. Colour as variable as the 

 dorsal lepidosis ; upper parts greyish, brownish, or reddish, uniform 

 or with more or less distinct angular darker spots ; frequently two 

 or three light bands along the back.

Very closely allied to the preceding, and apparently equally variable 

 in the dorsal lepidosis, and to be distinguished only by the presence 

 of a gular fold. The dorsal scales are subequal in specimen a ;
