Canthus rostralis rounded, supraciliary borders normally 

 raised ; occiput concave. Head-scales strongly keeled , those 

 below the ear a little larger, subequal ; ten to twelve upper 

 and nine or ten lower labials. Gular sac not much developed 

 (the specimen probably being a female) and covered with 

 small, almost smooth scales. Body compressed; nuchal and 

 dorsal crests subcontinuous, notched on the shoulder; the former 

 a little higher than the latter and formed of about six lanceolate 

 scales. Dorsal scales small, equal, hardly keeled, in transverse 

 series; ventrals much larger and strongly keeled. Tail com- 

 pressed, long, nearly three times and a half the length of head 

 and body. 



Bluish-brown above, with black spots along the base of the 

 dorsal crest and dark dots irregularly distributed ; limbs and 

 tail with indistinct dark bands. Lower parts whitish. Length 

 of head and body 130 mm.; tail 450 mm. (After Peters &

Head large, swollen below the ears, very distinct from neck; 

 snout longer than the diameter of the orbit ; tympanum much 

 larger than the eye-opening. Upper head-scales irregular, feebly
