Habit lacertiform ; the distance between the end of the snout and 
the fore limb is contained once and one fifth to once and one third in 
the distance between axilla and groin. Snout long, pointed, much 
depressed. Lower eyelid scaly. Nasals widely separated, usually 
divided into nasal and postnasal, not or but slightly deeper than the 
anterior loreal; no supranasal; frontonasal as long as broad or 
slightly broader than long, its anterior, convex border forming a 
broad suture with the rostral; the frontonasal frequently forming a 
suture with the frontal ; latter large, as long as or a little longer than 
the frontoparietals and parietals together, in contact with the first, 
second, and third supraoculars ; four supraoculars, subequal or first 
and fourth longest ; supraciliaries numerous, all, with the exception 
of the first two, very small; frontoparietals and interparietal dis- 
tinct, latter much smaller than former ; parietals forming a suture 
behind the interparietal; one to three pairs of nuchals; a large 
temporal, in contact with the outer border of the parietal; five 
labials anterior to the suboculars. Ear-opening small, usually with 
one or two small projecting rounded lobules on its anterior border. 
22 or 24 scales round the middle of the body (26 in the var. viridi- 
fuscum); dorsals largest, especially the two median series; all 
smooth, or dorsals feebly quadricarinate. Preanal scales not en- 
larged. The hind limb reaches the elbow of the adpressed fore 
limb, or nearly as far as the axil. Digits slender, with strong 
sharp claws, the basal phalanges cyclotetragonal, the distal strongly 
compressed ; subdigital lamellee smooth, 28 to 35 under the fourth 
toe. Heel with an enlarged suboval scale. Tail once and one 
third to once and a half the length of head and body. Green, olive, 
or brown above, with or without darker and lighter spots or black 
margins to the scales ; sometimes a more or less distinct light lateral 
band. Lower surfaces yellowish or pale green.
