Head rather large, once and three fifths to once and three fourths 
as long as broad, much longer than the tibia; forehead plane or 
scarcely concave ; a concavity behind the interorbital region in the 
adult male; upper head-scales hexagonal, strongly keeled, largest 
’ on the forehead ; scales of the supraorbital semicircles scarcely larger 
than the latter, separated by two or three rows of scales ; twelve to 
seventeen enlarged, keeled supraocular scales, separated from the 
supraorbitals by one row of granules; occipital as large as or a 
little larger than the ear-opening, separated from the supraorbital 
semicircles by three or four series of scales ; canthus rostralis sharp, 
canthal scales five or six; loreal rows five or six; seven or eight 
labials to below the centre of the eye; ear-opening moderately large, 
subtriangular. Gular appendage of moderate size, scarcely deve- 
loped in the female, with rows of distant .feebly-keeled scales ; 
gular scales very small, obtusely keeled. Body strongly compressed, 
with a dorso-nuchal crest of triangular scales ;. the crest scarcely 
distinct in the female. Dorsal and lateral scales granular, keeled, 
the latter somewhat smaller; ventral scales slightly larger than 
dorsals, subhexagonal, smooth. Limbs moderately long; the ad- 
pressed hind limb reaches the temple or the eye; digital expansions 
well developed; twenty-eight to thirty-two lamelle under pha- 
langes sr. and 111. of the fourth toe. Tail strongly compressed, with 
a crest of triangular scales much more developed than on the back; 
the caudal scales with annuli of strongly enlarged ones, forming 
very distinct segments ; length of the tail at least twice that of head 
and body. Male with slightly enlarged postanal scales. Green
