Head large in the male, with slightly swollen cheeks, moderate 

 in the female ; its width about once and two thirds in its length, 

 which exceeds that of the tibia ; forehead concave, occiput concave 

 in the male ; two feeble frontal ridges ; upper head-scales smooth 

 or a little rugose ; scales of the supraorbital semicircles very large, 

 in contact between the orbits ; eleven to thirteen enlarged, feebly 

 keeled supraocular scales, separated from the supraorbitals by one 

 or two rows of granules ; occipital as long as, but narrower than, 

 the ear-opening, separated from the supraorbitals by two series of 

 scales ; canthus rostralis sharp, canthal scales three ; six to eight 

 loreal rows ; six or seven labials to below the centre of the eye ; 

 ear-opening rather large, suboval. Gular appendage of moderate 

 size, scarcely developed in the female ; gular scales obtusely keeled. 

 Body short, compressed, in the male with a well-marked dorso- 

 Duchal fold. Dorsal scales minute, granular, considerably enlarged 

 and feebly keeled on the vertebral line ; ventral scales large, cycloid, 

 strongly imbricate, smooth. Limbs moderately long ; the adpressed 

 hind limb reaches between the orbit and the nostril ; digital expan- 

 sions rather narrow ; eighteen to twenty lamellae under phalanges 

 II. and III. of the fourth toe. Tail compressed, strongly in the male, 

 with feebly serrated upper edge ; its length not twice that of head 

 and body. Male with enlarged postanal scales. Grey-brown above, 

 with darker markings ; female with a pale vertebral line, and a 

 regular series of large, sharply defined, brown spots on each side of
