four shields; frontonasal longer than broad, separated from the 
rostral; two prefrontals; frontal strongly grooved; three large 
supraoculars, anterior smallest and sometimes broken up into two 
or three, the two others bordered externally, internally, and pos- 
teriorly with granules ; interparietal small, separated from the very 
small occipital by another small shield; an elongate shield on the 
outer border of the parietals; temporal scales granular, smooth ; 
no auricular denticulation ; lower eyelid scaly ; subocular usually

they form 24 to 27 straight transverse series. A large median 
preanal. The hind limb reaches the eye or a little beyond; toes 
strongly compressed; the length of the foot equals the distance 
between the arm and the nostril or the tip of the snout; a 
series of very large and one of smaller subtibial plates; scales 
on upper surface of tibia much larger than dorsals, rhomboidal, 
imbricate, keeled; a series of large, hexagonal, transverse shields 
on the upper surface of the arm. 15 to 18 femoral pores. Tail 
more than twice as long as head and body; upper caudal scales
