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. Two semicircles of scales border 
the preanal; two scales in front of the latter shield often much 
enlarged; the distance between the anterior femoral pores and 
the preanal 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.
