10. VTA 213 



enlarged supraoculars separated from frontal, frontoparie- 

 tal, and parietal plates by one or two rows of granules. Su- 

 perciliaries long, slightly projecting laterally, strongly im- 

 bricate. Central subocular very long, narrow and strongly 

 keeled. Rostral and six or seven supralabials long and low. 

 Symphyseal plate moderately large, and followed by a ser- 

 ies of plates separated from the infralabials, except first 

 pair, by one or two series of sublabial plates. Gular region 

 covered with small smooth subhexagonal granules, which in- 

 crease in size on, and are largest at edge of, strong trans- 

 verse gular fold. Ear-openings large with denticulation of 

 two to four scales, one being much larger than the others. 

 Skin of sides of neck and body more or less folded. About 

 five to eight rows of imbricate, keeled, more or less equal- 

 sized scales forming a band down the middle of back, and 

 changing very abruptly to small scales or granules on its 

 sides. Some of scales on upper lateral fold enlarged. Larg- 

 est scales on the tail, larger above than below, and strongly 

 keeled and pointed. Posterior surfaces of thighs and arms 

 covered with small granules similar to those on sides of 

 body. Superior and anterior surfaces of limbs provided 

 with keeled scales. Femoral pores about nine to 14 in 

 number on each thigh. Tail more than twice as long as 

 head and body. 



The general color above is grayish, becoming darker on 

 the sides and slightly tinged with yellow on the snout. On 

 the back are rather indistinct undulate blackish cross-bars, 

 which are often interrupted on the vertebral line and some- 

 times alternate. The tail is grayish with faint narrow rings 

 of brown or slate, more or less obsolete. The limbs are 

 cross-barred with dusky above. The lower surfaces are sil- 

 very white more or less flecked with black or slate. Males 

 have a yellow patch on the throat, and a long blue area on 

 each side of the belly, often with whitish dots.
