Upper head-scales sharply keeled ; canfchus rostralis and supra- 

 ciliary edge sharp, with strongly enlarged scales ; supraorbital scales 

 large, the inner series forming, with some enlarged scales on the 

 snout, a regular y\ -shaped figure ; interorbital region with four 

 or five longitudinal series of very small scales, nine to eleven upper 

 and as many lower labials. JJorsal scales unequal, the enlarged 

 ones sometimes forming regular longitudinal series ; lateral scales 

 small, with scattered enlarged ones ; ventral scales larger than 

 dorsals. Limbs covered with large subequal scales ; the hind limb 

 stretched forwards reaches far beyond the tip of the snout, the heel 

 reaching the eye or the posterior border of the orbit. Tail round, 

 slender, twice and a half as long as head and body, covered with 

 equal strongly keeled scales. Brownish olive above, sides darker ; 

 a dai-k-brown, light-edged cross band between the eyes, and more or 

 less distinct dark cross bands along the middle of the back ; gene- 

 rally a light oblique band from below the eye to the angle of the 

 mouth ; males generally with a light band along each side of the 

 back ; limbs and tail with more or less distinct dark cross bars ; 

 lower surfaces whitish, the throat brownish in the females and

Head-scales as in the preceding, but the interorbital scales only a 

 little smaller than the others, in two or three longitudinal series ; 

 the A -shaped figure formed by the keels of some of the scales 

 generally indistinct ; canthus rostralis less prominent ; nine or ten 

 upper and as many lower labials. A small pit on each side of the 

 neck, in front of the shoulder. Dorsal scales unequal, the enlarged 

 ones sometimes forming regular chevrons on the back, with the point 

 directed backwards, or a lateral longitudinal series, the latter always 

 distinct on the sacral region ; lateral scales a little smaller, with 

 scattered enlarged ones ; ventral scales much larger than dorsals. 

 Limbs above with large equal keeled scales ; the hind limb stretched 

 forwards reaches beyond the tip of the snout, the heel reaches the 

 tympanum. Tail round, slender, not twice as long as head and 

 body, covered with equal strongly keeled scales. Light brownish- 

 olive above, uniform, or with small scattered dark-brown spots on 

 the back and limbs ; a more or less distinct light, dark-edged 

 oblique band from below the eye to the mouth ; lower surfaces 

 whitish, the throat brownish in the young.
