16. CALOTES. 



319 



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

 region ; a few erect compressed scales behind the supraoiliary 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. TaU round, sub- 

 triangular, and with slight upper ridge at the base. Green, generally 

 with yellow or reddish spots and short bands. 



5. Calotes smaragdinus. 



Bronchocela smaragdina, Gwnth. Mept. Brit. Ind. p. 138. 



Upper head-scales small, keeled, slightly enlarged on supraorbital 

 region ; tympanum not half the diameter of the orbit. No gular 

 pouch ; anterior gular scales large, posterior smaller. No oblique 

 fold in front of the shoulder. Nuchal and dorsal crests scarcely 

 indicated ( $ ). 53 scales round the middle of the body ; dorsal 

 scales small, rather feebly keeled, the upper ones pointing straight 

 backwards, the others backwards and downwards ; ventral scales 

 much larger than dorsals, strongly keeled. The adpressed hind 

 limb reaches the tip of the snout or a little beyond ; third and fourth
