 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-

 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 suiooth, 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 aud fourth fingers nearly equal ; fourth 

 toe slightly longer than third, fifth extending beyond lii'st. 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, mucrouate, feebly keeled, forming regular
