Nostril lateral. Upper head-scales rather large, usually more or 
less distinctly striated ; an azygos frontal, seldom divided longitudi- 
nally, separated from the interparietal by a pair of fronto-parietals ; 
interparietal smaller than parietals; a series of three or four en- 
larged supraoculars; a single series of scales between the labials 
and the infraorbital ; temporal scales keeled; one or two projecting 
scales on the anterior border of the ear, and a long narrow band-like 
scale on the supero-anterior border. Sides of neck with a feeble longi- 
tudinal fold, the scales imbricate, keeled, pointed, smaller than those 
on the upper surface. Dorsal scales large, rhomboidal, very strongly 
keeled, ending in a sharp point; ventral scales smaller, rounded, 
smooth ; forty-two or forty-four scales round the middle of the body. 
The adpressed hind limb reaches hardly the axil in the female, the 
shoulder or a little beyond in the male; hinder side of thighs uni- 
formly granulate. Two to four anal pores in the male. Tail about 
twice as long as head and body; caudal scales (except the basal 
ones) smaller than dorsals. Brownish above, with golden or coppery 
gloss; two light yellowish streaks on each side from the eye to the 
hind limb, the lower passing on the upper border of the tympanum ; 
a series of transverse or angular blackish-brown spots on each side 
of the back, separated by the lighter vertebral zone, which is imma- 
culate; seldom a black vertebral line; usually a series of black 
spots between the light lateral bands; a whitish streak or a series 
of whitish spots on the back of the thighs ; lower surfaces yellowish 
white, immaculate or spotted with brown on the throat and breast.
