368 Reptilia and Amphibia from Central India. [No. 4, 



race. These specimens shew precisely the same proportions of the 

 limbs as I find usual in the smaller race, the hind foot laid for- 

 ward extends just beyond the snout, while the fore limb laid back 

 does not reach, or, at the most, just reaches the vent. The dorsal 

 scales are enlarged, but there is an absence of enlarged scales on 

 the sides, and although one or two occur on the occiput, they are 

 much less distinct and less numerous. The gular pouch is well 

 developed, being 1| inches long at its union with the throat 

 and head, or nearly three times as long as in the smaller race, but 

 as I have previously stated, I am not sure that I have a specimen 

 of the latter with a fully developed pouch. The following are the 

 dimensions of the three larger specimens.

The weight of the body must be far more than double that of 

 the smaller specimens. 



There is evidently very little difference between these forms of 

 Sitana except size, as will be seen from the preceding details. I 

 have obtained specimens of both races which, agreeing with each 

 other, differ from both the forms described byGiinther in the 

 length of the legs. I shall endeavour to procure further specimens, 

 and to decide if all these varieties pass into each other by insen- 

 sible degrees, or whether there are really two races distinguished 

 by the marked difference in size. The former appears to me the 

 more probable at present. 



1 9. Charasia dorsalis, Gray. 



A fine rock lizard which I found abundantly in parts of Central 

 India puzzled me greatly. I could not conceive it probable that 

 so conspicuous a species had escaped notice, but nevertheless no 

 generic description in Giinther's Eeptiles would apply to it. 

 In all but one character it agreed with Charasia dorsali*, but that 

 character, the arrangement of the scales on the tail, is mentioned 

 "by Dr. Giinther as one of the principal distinctive marks, and
