[Dec. 19, cuspid, strongly keeled ; nine scales, taken in the middle of the back, correspond to the distance from the end of the snout to the posterior border of the occipital shield ; they are arranged in 42 to 44 transverse series (from occipital shield to line of hinder side of thigh) and 11 longitudinal series (a line drawn on each side from the upper edge of the ear-opening, and which corresponds in this species with the outer border of the yellowish band, being taken as the boundary between the dorsal and lateral scales); lateral scales smaller, tricuspid and strongly keeled, directed upwards; abdominal scales smooth, distinctly bi- or tricuspid, two thirds the size of the dorsals. Femoral pores 12 or 13 on each side. Limbs moderate; carried forwards, the fore limb extends beyond the snout the length of the claws of the longest fingers, the hind limb reaches the collar-fold in the male, a little beyond axilla in the female. The female exhibits the following coloration :-Upper surface of head, limbs, and tail uniform light reddish brown; a purplish-grey vertebral band, ending at base of tail; on each side two reddish-brown longitudinal bands separated by a yellowish-white narrower band commencing from the eye ; a second light band from axilla to groin ; more or less obsolete blackish markings, obliquely directed backwards, across the dark dorsal bands ; an obsolete blackish streak at base of humerus ; lower surfaces yellowish white, immaculate. The male differs in the following points :-the interval between the two yellowish-white lateral bands darker, blackish : an intensely black streak from collar-fold to forearm ; a small greenish-blue spot on each side of the throat, bordered anteriorly by a few greyish dots ; an elongate iridescent greenish-blue black-margined spot on each side of the belly, the white interspace between them being twice their width.
