648 Notices and Descriptions of various Reptiles. [No. 7. 



but the colouring is remarkable, and different again from that of Mr. 

 Jerdon's supposed C. Kouxi of S. India. Pit before the shoulder 

 more developed than in C. mystacetjs, and partially black. Hind- 

 toe reaching to the eye. A row of 3 or 4 raised spines above the 

 tympanum ; and nuchal crest moderate and gradually diminishing 

 to the tail. The latter is tumid at base, and soon attenuates ra- 

 ther suddenly, the tumid portion exhibiting a median ridge of very 

 broad keeled scales. Caudal scales towards the base of tail much 

 larger than those of the body. Throat scales very broad and flat, with 

 a median row of narrow compressed scales imparting the appearance 

 of a small fanon or dewlap. A half-grown specimen (in spirit) is 

 blue, with the tail reddish-brown to near its base, and marked with 

 an irregular double series of ocelli which are white, having a black 

 border. A few similar ocelli are seen bordering the low spinal crest. 

 There is a black mark between the eye and the ear, and another 

 below the eye ; and a tinge of ruddy on the throat, about the tym- 

 panum, and on the occipital and tympanic spines. Adults (in 

 spirit) have the body and limbs blue, the tumid base of tail green, 

 and the rest of the tail dull red-brown, with ocelli less bright than 

 in the young. Borders of lips black, continued as a broad black 

 band (more or less variegated with ruddy-white) to the shoulder-pit. 

 Throat whitish tinged with ruddy and strongly contrasting, as also 

 a white band from the tympanum continued over and passing the 

 shoulder-pit. In some, the shoulder-pit is also posteriorly margined 

 with a white mark ; and raising the fore-leg, two or three additional 

 white stripes are seen, oblique and successively more inclining to 

 the horizontal. The limbs are also banded with white ; but these 

 markings are often indistinct or obsolete. Tumid base of tail bright 

 orange underneath in some specimens. C. Botjxi is described from 

 Burma ; but as we possess the preceding species both from Burma 

 and the mountains of Ceylon, it is the less improbable that the pre- 

 sent may have the same habitat. 



4. C. gigas, nobis. (Supposed C. ophiomachtjs, J. A. S. XI, 

 870). Resembles C. veesicoloe, except in being much larger, 

 having no trace of gular fanon, and a double nuchal crest of spine- 

 like scales, ^ in. long in the specimen under examination. Dorsal 

 crest also proportionally more developed than in C. veesicoloe,
