A very common lizard wherever it occurs and always frequent- 

 ly met with, owing to its boldness and conspicuovis habits. 



Apart from the orange or red wash on the shoulders and flanks 

 which is probabl}' assumed in the breeding period and thus is not 

 constant, three colour phases occur in the present series. In the 

 first the back and sides are unmarked, except for a black dorso- 

 lateral line. In the second, the back is marked b}^ five black 

 lines running between the rows of scales, which become in- 

 distinct posteriorly ; between the outer of these lines and the dark 

 line defining the back from the sides, two rows of scales occur. In the 

 third the shoulders and sides are irregularly^ spotted with white, and 

 the dorsal region may be either striped or plain.
