is defined by two nasals, an upper and a lower, separated from 

 each other posteriorly by head-granules ; ear-opening very small, 

 obscure, oblique in position, the lower border being anterior ; 

 rostral broad, pointed, convex from before backwards, in the form 

 of a beak, and with a well-defined groove in the mesial, dorsal 

 line of its proximal half. Q-enerally 7 upper and 7 lower labials, 

 but there may be as many as 8, and as few as 6. Limbs mode- 

 rately long ; the hind limb when laid forwards reaches to the 

 front border of the eye. Toes moderately long. The upper 

 surface covered with minute, slightly convex granules, somewhat 

 larger on the front of the head, but not markedly so, and smallest 

 on the nape of the neck. The granules on the front of the fore 

 limb and thigh are somewhat large and imbricate. The scales 

 on the under surface of the body are larger than those on the 

 back, and there are no erect spiny scales on the median Une of 

 the belly. Tail laterally compressed, not tapering to a fine 

 point, but eitlier truncated with a rounded end, or abruptly 

 pointed, and covered with subquadrangular, flattened scales, 

 larger than those of the body, and arranged, more or less, in 

 verticils, with a rather feeble, serrated ridge along the dorsal and 

 ventral lines. 



G-eneral colour (in alcohol) pale greyish fawn, grey-brown, or 

 even grey. Six or more quadrangular, transverse, brownish 

 markings along the back from the nape to the sacral region, 

 sometimes with pale posterior margins, and occasiimally divided 

 down the back by a pale mesial band. Externally to these dark 

 squares, there are from 6 to 7 parallel lines of red spots, either 

 rounded, or linear, the upper lines beginning behind the eye and 

 the lower ones in the axilla. The labials are generally more or 

 less blurred with blackish, this colour also invading the sides of 

 the head, with yellowish granules intermixed. A narrow, purplish- 

 black collar from side to side across the neck. Upper surfaces 

 of the limbs more or less barred with black. Middle of the 

 throat, chest, belly, and under surfaces of the limbs whitish. 

 The tail barred like the back.
