 longer than the diameter of the orbit ; forehead not concave ; ear- 

 opeping rather large, oval, vertical, the upper part concealed under 

 a fold of the skin. Six larger incisor teeth. Limbs very long, the 

 hind limb when stretched forwards reaching the eye ; digits very

 with small flat granules, largest on the snout. Abdominal scales 

 smaller still, convex, those on the median line pointed and erect.

 median cleft; nostril pierced between two large and one very 

 small nasal, separated from rostral and labials ; eight upper and 

 seven lower labials ; mental large, subtrapezoid ; no chin-shields. 

 Tail shorter than the body, strongly compressed, in profile rounded at 

 the extremity, which is a little higher than the base, furnished above 

 with a much-developed crest of closely set slender linear scales. 

 The life-coloration is as follows, according to Carter : — " Ground 

 cinereous, six pairs of white spots between the back of the head and 

 root of tail, symmetrically placed ; six to eight lines of red spots on 

 each side, broken and terminating in small points towards the beUy ; 

 buif- coloured irregular spots on the sides among the red lines ; belly 

 bright yellow, passing into cinereous towards the roots of the pos- 

 terior and anterior extremities ; legs and tail spotted with red towards 

 their proximal ends, with white spots towards their extremities ; 

 head irregularly marked with red and white spots having a trans- 

 verse direction."
