140 AGAMIES. 



crest. 60 scales round the middle of the body, dorsals largest and 

 smooth or indistinctly keeled ; on the anterior half of the body 

 the scales point upwards and backwards, on the hinder half nearly 

 straight backwards ; ventrals two thirds the size of dorsals, mu- 

 cronate. The hind limb reaches the posterior border of the orbit. 

 Greenish, with six large orange spots across the back, separated 

 by dark bands ; sides with a black network ; black lines radiate 

 from the eye.

 Calotes liolepis, Souleng. Cat. Liz. i, p. 326, pi. xxv, fig, 2. 



Upper head-scales smooth, imbricate, strongly enlarged on supra- 

 orbital region ; two distinct spines on each side of the back of the 

 head, between the ear and the nuchal crest ; diameter of the tym- 

 panum nearly half that of the orbit. Gular sac not developed 

 ( $ ) ; gular scales strongly keeled, as large as ventrals. A short 

 oblique fold in front of the shoulder. Nuchal crest formed of 

 narrow separated spines, the longest of which measure about the 

 diameter of the tympanum ; dorsal crest quite indistinct. 35 to 

 39 scales round the middle of the body ; dorsal scales three times 

 as large as ventrals, squarish, smooth, pointing backwards and 

 downwards ; ventral scales strongly keeled. The adpressed hind 

 limb hardly reaches the tympanum ; third and fourth fingers equal. 

 Tail round. Pale olive, with indistinct brown transverse bands on 

 the back ; brown lines radiating from the eye, the lower reaching 

 down to the lower lip. 



From snout to vent 3 inches ; tail 7.

Upper head-scales smooth, imbricate, enlarged on supraorbital 

 region ; two groups of spines on each side of the head, between the 

 ear and the nuchal crest ; tympanum nearly half the diameter of 

 the orbit. Gular sac not developed ; gular scales feebly keeled, 

 nearly as large as ventrals. A short oblique fold in front of the 

 shoulder. Dorso-nuchal crest composed of closely set lanceolate 

 spines directed backwards, with smaller ones at the base ; in the 

 male the height of the crest on the nape equals or exceeds the 

 diameter of the orbit, and decreases gradually on the back. 31 to 

 35 scales round the middle of the body ; dorsal scales very feebly 

 keeled, or even quite smooth, with the points directed upwards and 

 backwards ; ventral scales larger than dorsals, very strongly keeled 

 and mucronate. The adpressed hind limb reaches the anterior bor- 

 der of the orbit or a little beyond ; third and fourth fingers nearly 

 equal. Tail round. Green above, frequently with blackish- green
