 supranasals distinct ; frontal a little longer than broad ; fourth 

 labial entering the orbit. Body much elongate ; sides of belly 

 angular. Scales perfectly smooth, 24 round the middle of the body. 

 Fore limb very small, didactyle, about as long as the snout ; hind 

 limb proportionately much more developed, tetradactyle, as long as 

 or a little longer than the distance between the eye and the fore 

 limb. Tail, when intact, about two thirds the length of head and 

 body. Yellowish above, with nine or eleven longitudinal pale brown 

 streaks, the three median and the outer sometimes darker than the
