slightly louger than, the ti])ia ; forehead concave, frontal ridges very- 

 short, or indistinct ; upper head-scales strongly keeled ; scales of the 

 supraorbital semicircles enlarged, separated by one or two series of 

 scales ; a few enlarged, strongly keeled supraocular scales, irregu- 

 larly arranged ; occipital as large as, or a little lai'ger than, the ear- 

 opening, separated from the supraorbitals by two or three series of 

 scales ; canthus rostralis angular, canthal scales three ; loreal rows 

 six : six or seven upper labials to below the centre of the eye ; ear- 

 opening rather large, vertically oval. Gular appendage large, ex- 

 tending posteriorly beyond the thorax, scarcely indicated in the 

 female ; gular scales keeled. Body slightlj" compressed in the male ; 

 no dorso-nuchal crest. Dorsal scales rhomboidal or hexagonal, sub- 

 imbricate and keeled, graduating into the small keeled granules of 

 the sides ; ventrals larger than dorsals, rhomboidal, imbricate, 

 sharply keeled. The adpressed hind limb reaches the eye or the 

 anterior border of the orbit ; digits rather feebly dilated ; thirteen or 

 fourteen lamellae under phalanges it. and iii. of the fourth toe. Tail 

 cylindrical, not quite twice as long as head and body, covered with 

 large, equal, strongly keeled scales. jN^o enlarged postanal scales. 

 Brownish above, with metallic gloss ; usually a paler vertebral band ;
