rarely 4 *, upper labials anterior to the subocular, which is a little 

 narrower beneath than above. A long narrow upper temporal, 

 usually in contact with the fourth supraocular, followed by one 

 or two small shields ; temporal scales mostly hexagonal, very 

 small above, larger beneath ; a narrow curved tympanic shield. 



5 pairs of chin-shields, first three in contact in the middle ; 29 

 to 34 gular scales in a straight line in the middle, granular in 

 front, gradually or abruptly enlarged and imbricate towards the 

 collar ; no gular fold. Collar with strongly serrated edge, com- 

 posed of 7 to 10 plates. 



Scales granular and smooth on the nape, rhombic, juxtaposed 

 or subimbricate, and obtusely keeled on the body ; 4 or 6 series 

 of hexagonal plates along the back, more or less strongly keeled ; 

 38 to 42 plates and scales across the middle of the body t ; 12 or 

 14 large keeled scales in a transverse series between the hind 

 limbs. Ventral plates in 6 longitudinal and 28 to 31 transverse 

 series, the border of the transverse series feebly notched between 

 the plates, the median pair of which is narrower than the others. 

 Praeanal plates small and irregular, or two large one in front of 

 the other, or three large forming a triangle. 



14 to 16 femoral pores on each side. 33 to 35 lamellar scales 

 under the fourth toe. 



Caudal scales in alternating somewhat longer and shorter 

 whorls, upper oblique, strongly and diagonally keeled, rounded 

 or obtusely pointed behind, lower keeled ; 26 to 30 scales in the 

 fourth or fifth whorl behind the postanal granules. 



Brown to blackish above, with six yellowish-white streaks, two 

 along the back, diverging on the nape, and two on each side, the 

 upper from behind the eye to the base of the tail, passing above 

 the tympanum, the lower from the upper lip, through the tym- 

 panum and above the fore limb, to the base of the thigh ; the 

 dark band between the two light lateral streaks sometimes 

 spotted with whitish ; upper surface of head and limbs pale 

 brown ; lower parts white ; tail pale brown above, yellowish 

 beneath, orange-reel distally in the young.
