182 Indian and Malayan Amphibia and Reptilia. [No. 3, 



My largest specimen measures 15 inches, of which the tail is 

 about 11 inches. 



This is a true arboreal lizard, tolerably common at the Andamans, 

 and very common at the Nicobars. I found the jungles on Nancowry 

 and Camorta swarming with specimens. They are extremely quick, 

 and almost within a moment after they were first noticed they are 

 again seen some twenty or thirty feet high upon a tree ; and when 

 followed # up they do not hesitate to leap from one tree to another. 

 "Without shooting them it is scarcely possible to procure a speci- 

 men. I obtained more than a hundred specimens from the 

 Nicobars alone, thinking that there may be a possibility of tracing 

 some permanently distinctive characters in the Nicobar form, but 

 they all proved identical with the Andaman species which was first 

 described by Mr. B 1 y t h from Port Blair. There cannot be the 

 least doubt of the two being the same, and I cannot even see any 

 real generic distinction from Tiaris, as emended by G r a y. Fitz- 

 i n g e r ' s name Coryplioplnjlax must, therefore, be considered as a 

 synonym of the former.

This species appears to be more common in the jungles of the 

 Wellesley Province and near Malacca, than it is on Penang itself. 

 Cantor's description of the colours is excellent, the metallic 

 bronze brown hue of the live lizard is wonderfully fine and brilliant. 

 The black spot between the eyes appears quite constant, at least in 

 male specimens. I only observed the gular sack to be uniform yellow, 

 the lateral appendages and the throat are very pale or almost quite 

 white and dark spotted. Limbs and tail are brown banded. 

 There is behind the large rostral shield, a short longitudinal sharp 

 ridge distinct, dividing in two, one branch leading to each eye. Be- 

 side the enlarged tubercular scale above the posteroirpart of the orbit, 

 there are 3 — 4 enlarged flattened scales placed in one row behind the 

 orbit, and two small spines are above and one behind the tympa- 

 num. In most of the specimens there are also some larger spiny 

 or tubercular scales conspicuous on the sides of the neck, as if 

 indicating lateral crests which appear to be fully developed in
