Upper head -scales smooth, imbricate, enlarged on supraorbital 

 region ; no spines whatever on the side of the head ; tympanum 

 measuring a little more than half the diameter of the orbit. Gular 

 pouch not developed ; gular scales much larger than ventrals, rather 

 feebly keeled. An oblique fold in front of the shoulder. Nuchal 

 crest composed of narrow spines the length of which equals the 

 diameter of the tympanum ; dorsal crest a mere serrated ridge. 

 Forty- five scales round the middle of the body; dorsal scales feebly 

 keeled, the upper ones pointing straight backwards or slightly up- 

 wards, the others downwards and backwards ; ventral scales strongly 

 keeled, nearly the same size as the dorsals. The adpresed hind 

 limb reaches the eye ; third and fourth fingers equal. Tail round, 

 the scales of its basal part very large and hard, those of the median 

 upper row forming a serrated edge. Pale olive-green, above with 

 transverse bands of a darker green ; four angular reddish-brown 

 cross bands on the back ; a dark streak from the eye to above the 

 tympanum ; limbs and tail with alternate lighter and darker cross 

 bands.
