supranasals distinct; frontal a little longer than broad; fourth 
labial entering the orbit. Body much elongate; sides of belly

limb proportionately much more developed, tetradactyle, as long as 
or a little longer than the distance between the eye and the fore

body. Yellowish above, with nine or eleven longitudinal pale brown 
streaks, the three median and the outer sometimes darker than the
