separated from it by one or two small shields* or by tlie parietals 

 meeting in the middle,t rarely absent.J Two supraoculars, the first 

 longer than its distance from the anterior loreal, the space in front 

 of it filled by 3 to 8 scales ; 6 or 7, rarely 5 or 8, superciliaries, 

 first longest, separated from the supraoculars by a series of small 

 granular scales or by one series in front and two behind. Three 

 nasals, lower in contact with the rostral and the first upper labial, 

 posterior small ; anterior loreal IJ to 2 times as long as deep, shorter 

 than the second ; 4 or 5, rarely 3 or 6, upper labials anterior to the 

 subocular, which is keeled below the eye and largely borders the mouth, 

 its lower border much shorter than the upper. Temporal scales 

 granular, smooth ; a narrow tympanic shield ; uo auricular denticula- 

 tion. Lower eyelid opaque or semitranspareut, with numerous enlarged 

 scales in the middle, one of which may be much larger than the others. 



4 pairs of chin-shields, the first three in contact in the middle. § 

 24 to 38 gular scales in a straight line Vjetween the symphysis of 

 the chin-shields and the median collar-plate; no gular fold. Collar 

 straight, free, composed of 7 to 11 plates. 



Scales juxtaposed, granular, smooth, larger towards the ventrals, 

 47 to 65 across the middle of the body. Ventral plates in 12, 

 rarely 10, regular longitudinal and 28 to 33 transverse series ; the 

 plates of the median and outer series as long as broad or longer than 

 broad, the others as long as broad or a little broader tlian long. 

 Preanal region usually with small irregular plates, exceptionally with 

 one or two enlarged plates, or witli three forming a triangle. 



Scales on upper surface of fore limb large, smooth or obtusely 

 keeled ; lower surface of forearm with a series of transversely 

 enlarged scales. Scales on upper surface of tibia rhombic, feebly 

 imbricate, keeled, much larger than dorsals; one series of very 

 large and one of small plates on the lower surface. 10 to 16 femoral 

 pores on each side, usually 12 to 16. Subdigital lamellse bicarinate, 

 spinulose, 24 to 30 under the fourth toe. 



Upper caudal scales oblique, truncate behind, strongly and dia- 

 gonally keeled ; basal subcaudals smooth or obtusely keeled ; 24 to 

 32 scales in the fourth or fifth whorl. 



The young is elegantly streaked with black and white on the body. 

 There are 5 or 7 black streaks as wide as or wider than the inter-

§ A male from Ky Ky is exceptional in having 5 pairs of chin-shields, the 

 first 4 in contact in the middle.
