[2] Its head is rather elongated; the snout is obtusely pointed, longer than the distance between the eye and the ear opening, l.5 the diameter of the orbit; the forehead is not concave; the ear opening is small and oval.

Its digits are slender, the basal part is not dilated, scarcely wider than the distal, and with enlarged plates beneath.

The snout is covered with suboval keeled granules; the rest of the head is minutely granulate; the rostral is twice as broad as deep, with median emargination and cleft above; the nostrils are pierced between the rostral and three or four nasals; seven or eight upper and as many lower labials are found; the mental is large and triangular, with a truncated posterior angle; numerous small chin-shields pass gradually into the gular granules, which are feebly keeled.

The tail is cylindrical, tapering, above with very small keeled scales and annuli of spine-like tubercles, beneath with larger scales, but no transversely dilated median plates.

In color, it is brown above, variegated with darker and lighter; these variegations generally form transverse markings on the back and tail; sometimes, a light vertebral band occurs; the spine-like tubercles on the flanks are white; its lower surfaces are light brown or dirty white; the throat is sometimes blackish.
