the diameter of the orbit ; dorsal crest a mere serrated ridge. 57 

 to 97 scales round the middle of the body ; dorsal scales keeled, 

 much smaller than ventrals, the upper ones directed upwards and 

 backwards, the others downwards and backwards. The adpressed 

 hind limb reaches between the eye and the tip of the snout ; third 

 and fourth fingers equal or nearly so, about as long as the fifth toe. 

 Tail round, subtriangular at the base. Green, uniform or with 

 reddish markings. 



From snout to vent 4-8 inches ; tail 15. 



Hab. Malay Archipelago and Peninsula as far north as Tenas- 

 serim.

Upper head-scales moderate, keeled, not enlarged on supraorbital 

 region ; a few erect compressed scales behind the supraciliary edge ; 

 tympanum half or more than half the diameter of the orbit. Gular 

 pouch well developed : gular scales keeled, smaller than the ventrals. 

 No oblique fold in front of the shoulder. Nuchal crest large, com- 

 posed of falciform spines directed backwards, the longest equalling 

 or exceeding the diameter of the orbit, with several irregular rows 

 of smaller spines at the base ; dorsal crest well developed, though 

 much less so than the nuchal, gradually decreasing in size towards 

 the posterior part of the body. 43 to 53 (exceptionally 65) scales 

 round the middle of the body ; dorsal scales keeled, smaller than 

 the ventrals ; the scales of the row contiguous to the dorsal crest 

 point upwards and backwards, those of the next row point straight 

 backwards, all the others backwards and downwards. The adpressed 

 hind limb reaches between the eye and the tip of the snout ; third 

 and fourth fingers equal, about as long as the fifth toe. Tail 

 round, subtriangular, and with slight upper ridge at the base. 

 Green, generally with yellow or reddish spots and short bands. 



From snout to vent 5 inches ; tail 17.

Upper head-scales rather large, smooth or feebly keeled, imbri- 

 cate, more or less enlarged on supraorbital region ; two well- 

 separated spines (seldom absent or scarcely distinct) on each side 

 of the back of the head, above the ear ; tympanum half, or less than 

 half, the diameter of the orbit. Gular pouch not developed ; gular
