Snout nearly twice as long as diameter of orbit ; upper head- 

 scales rather large, unequal, tubercular; male with a small tubercle 

 on the tip of the snout ; 8 to 10 upper and as many lower labials ; 

 gular scales feebly keeled, smallest on the median line. Nuchal 

 crest composed of 3 or 4 lanceolate spines, the longest of which 

 about equals the diameter of the orbit ; dorsal crest non-continuous 

 with the nuchal, composed of 12 to 14 similar lobes separated from 

 one another ; in the female the lobes of the crest are shorter and 

 not raised, but bent sideways on the back. Dorsal scales very 

 large, irregular, imbricate, smooth or shortly keeled, the keels 

 pointing downwards and backwards ; ventral scales small, lanceolate, 

 strongly keeled, mucronate. Scales on the limbs irregular, 

 keeled, some slightly spinose ; fingers and toes not very long, 

 third slightly shorter than fourth ; infradigital scales feebly 

 keeled ; the adpressed hind limb hardly reaches the axil. Tail 

 feebly compressed, covered with keeled scales which are smaller 

 beneath ; its length is not once and a half that of head and body. 

 Olive above, with irregular dark-brown cross bands; a light, 

 reddish-brown to cream-coloured band from the end of the snout 

 on the upper lip to above the shoulder ; a cream-coloured spot 

 on the nape and a cross band of the same colour on the anterior 

 part of the back ; lower lip with a broad dark-brown margin ; 

 more or less distinct oblique brown lines on the sides ; tail with 

 dark annuli. 



From snout to vent 2-6 inches ; tail 2-9.
