Head large ; its width equals twice the distance from the end of 

 the snout to the orbit, or from the orbit to the ear-opening ; snout 

 subtriangular, obtuse, once and three fifths or once and two thirds 

 the diameter of the orbit ; forehead concave ; ear-opening narrow, 

 oblique, its vertical diameter at least half the diameter of the orbit. 

 Body and limbs moderate ; digits free. Head covered with small 

 convex polygonal scales ; upper labials twelve to fourteen, first 

 entering the nostril ; lower labials ten or eleven, gradually de- 

 creasing in size ; mental very variable in shape ; chin-shields four 

 or five on each side, smaller than the labials, the inner pair generally 

 not longer than the mental. Back covered with small juxtaposed flat 

 granules and about twelve longitudinal series of mamilliform tuber- 

 cles ; throat with flat granules ; abdominal scales moderately large. 

 Pores in a short angular series on the prseanal region, thirteen to 

 twenty-four altogether. Tail (when intact) slightly depressed, 

 tapering, distinctly annulate, covered with subquadrangular smooth 

 scales, much larger beneath, arranged in transverse series ; each 

 annulus is composed of five or six transverse rows of scales above, 

 three beneath : also, on the upper surface, large conical tubercles, 

 wide apart and symmetrically arranged. Slaty grey above, with red 

 spots or vermiculations ; tail annulate with darker and lighter ; 

 lovN'er surfaces whitish, frequently indistinctly variegated with grey.
