The shields behind the nostril very variable : frequently two 



superposed postnasals ; anterior loreal sometimes absent. Median 



dorsal scales often graduating into the laterals ; 36 to 52 scales 



across the middle of the body. Tvro semicircles of scales border 



the praeanal ; two scales in front of the latter shield often much 



enlarged ; the distance between the anterior femoral pores and 



the praeanal usually equals or exceeds the length of that shield. 



Young usually with three well-marked light longitudinal streaks 



along the back, and series of whitish ocelli on the sides ; some 



specimens uniform olive-green : lower surfaces whitish, unspotted. 



The dorsal streaks of the young constantly persist in the adult 



female, and usually at least traces of them are seen in the 



males, female brown above, usually with two series of large 



dark-brown spots on the back and more or less distinct ocelli on 



the sides ; lower surfaces uniform yellowish white or scantily 



spotted with black, Male frequently entirely green above, dotted 



or spotted with black, with or without white ocelli on the sides ; 



lower surfaces greenish, black-spotted.
