It has a snout rather acuminate, as long as the distance between the eye and the upper border of the ear-opening, 1.3 the diameter of the orbit; forehead concave; interorbital space very narrow; upper eyelid strongly fringed; ear-opening large, obliquely crescentic, the concavity being directed forwards and upwards, its diameter equalling three fourths that of the eye.

Snout covered with large convex granular scales, largest between the eye and the nostril; hinder part of head with minute granules, and scattered ones of a larger size.

Upper surface of body covered -with small irregular flat grannies and moderately large, trihedral, strongly keeled tubercles arranged in 14 or 16 rather irregular longitudinal series; the largest tubercles measure about one fourth the diameter of the eye.

Tail cylindrical, tapering, covered above with small, irregular, imbricate smooth scales and scattered pointed tubercles forming four or six longitudinal series, beneath with a series of transversely dilated plates.

Pale yellowish brown, with six faint brownish transverse narrow dorsal bands, the tubercles in these areas being almost black; a dark brown streak from the nostrils through the eye above the ear, with a whitish line above it; lips whitish.
