Upper head-scales smooth, imbricate, not or but slightly enlarged 

 on supraorbital region ; a short series of three to six small spines 

 above and behind the posterior part of the tympanum ; latter mea- 

 sui ing haK, or more than half, the diameter of the orbit. Gular 

 pouch not developed ; gular scales more or less distinctly keeled, as 

 large as ventrals. A strong oblique fold or pit in front of the 

 shoulder. Dorso-nuchal crest composed of small lanceolate spines, 

 the longest of which, on the nape, measure about two thirds the 

 diameter of the orbit ; on the back the crest is very distinct, but 

 the spines gradually decrease in size. Forty-three to forty-seven 

 scales round the middle of the body ; dorsal scales rather feebly 

 keeled, the upper pointing straight backwards, the others downwards 

 and backwards ; ventral scales much larger than dorsals, very 

 strongly keeled, mucronate. The adpressed hind limb reaches the 

 eye ; third and fourth fingers equal. Tail round ; in the males the 

 scales on the basal part of the tail very large and hard, those of the 

 median upper row forming a slightly serrated ridge. Green, uniform 

 on the back and tail, or with angular whitish black-edged angular 

 cross bars or ocelli, with or without a reddish-brown vertebral band ; 

 lips and sides of head with a broad black band or variegated with 

 black in the male ; female usually with a white, black-edged hori- 

 zontal streak below the eye.
