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, 

 oanthal 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 lameUse under pha- 

 langes n, and iii. of the fourth toe. Tail strongly compressed, with 

 a crest of triangular scales much more developed than on the back ; 

 the caudal scales with aunuli 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 

 above, with more or less distinct reddish or whitish oblique trans- 

 verse bands on the body ; female with a vertebral series of round 

 light spots ; lower surfaces greenish white.
