Acanthosaura armata, part., Blanf, Joum. As. Soc. Beng. xlviii. 1879, 

 p. 130. 



Snout as long as tlie diameter of the orbit ; canthus rostralis and 

 supraeiliary edge angular ; tympanum smaller than the eye-opening ; 

 upper head-scales rather feebly keeled, much larger on the supra- 

 orbital region ; a spine, measuring half the diameter of the orbit, 

 terminates the supraeiliary edge ; nine or ten upper and as many 

 lower labials ; gular scales strongly keeled, much smaller than the 

 ventrals. An oblique fold down each side of the neck, in front of 

 the shoulder ; a spine of the same size as the postorbital on each 

 side of the nape, above the tympanum. Nuchal crest not continuous 

 with the dorsal, composed of large compressed spines a little longer 

 than the postorbital ones, with the base concealed by two or three 

 rows of smaller spines. Dorsal crest much lower than the nuchal, 

 gradually decreasing in size, reduced posteriorly to a very feeble 

 denticulation. Dorsal scales extremely smaU, with the point di- 

 rected upwards, intermixed with irregularly scattered, enlarged, 

 rhomboidal strongly keeled scales ; ventral scales larger than the 

 enlarged dorsals, strongly keeled. Fore limb and tibia above with 

 equal keeled scales, femur with unequal ones ; fourth finger very 

 slightly longer than third; the adpressed hind limb reaches the 

 anterior border of the orbit in the female, the end of the snout in 

 the male. Tail compressed, nearly twice as long as head and body, 

 covered with uniform strongly keeled scales, which are larger infe- 

 riorly. Pinkish grey above, with brown spots and marblings en- 

 closing roundish light spots ; a large cruciform dark-brown marking 

 on the nape, the lateral branches descending along the antehumeral 

 fold to the throat ; eyelids and a streak from the end of the snout 

 to the tympanum, through the orbit, dark brown ; limbs and tail 

 with dark and light cross bands.
