Head depressed, triangular ; nostril rather large, slightly tubular, 

 pierced on the canthus rostralis; upper head-scales smooth; occipital 

 not enlarged ; borders of the tympanum and sides of neck with 

 groups of well- developed spines ; ear-opening much larger than the 

 eye-opening. Throat strongly plicate ; no gular pouch ; a trans- 

 verse fold on the neck. Body depressed ; a distinct curved fold 

 from the neck to the sides ; dorsal scales rather large, rhomboidal, 

 strongly imbricate, shortly mucrouate, keeled, the keels forming 

 oblique lines converging towards the vertebral line ; flanks with 

 minute scales ; ventral scales smooth, much smaller than dorsals 

 and much larger than laterals. Limbs strong, digits compressed ; 

 scales on upper surface of limbs as large as the dorsals, or a 

 little smaller ; third and fourth fingers nearly equal ; fourth 

 toe slightly longer than third, fifth extending beyond first. Tail 

 round or slightly compressed, depressed at the base, nearly three 

 times as long as the distance from gular fold to vent ; caudal 

 scales larger than dorsals, mucronate, feebly keeled, forming regular 

 annuli. Male with a patch of thickened praeanal scales and a 

 similar patch of ventral scales. Yellowish brown above, uniform or 

 with a darker network of dots ; fore limbs dusky or blackish ; 

 posterior half of tail black, or annulate with black ; gular region 

 marbled yellow and dark blue. 



Prom snout to vent 6 inches ; tail 12. 



A variety (fusca, Blanf.) is distinguished by having the transverse 

 nuchal fold less distinct, and the spines on the sides of head and 

 neck rather longer. General colour blackish brown, throat yellowish.

 small, granular ; vertebral region with enlarged flat, feebly keeled, 

 rather irregular scales; flanks with enlarged, strongly keeled or 

 spinose scales ; no nuchal denticulation ; ventral scales smooth, 

 distinctly smaller than the enlarged dorsals. 150 to 160 scales
