The enlarged scales on the hack, and especially at the sides of the body, 

 are invariahly well marked, hut less numerous in female than in male speci- 

 mens ; they are during life yellow or golden, and during the breeding season 

 often tinged rosy, or even vermilion. In Northern India the species does not 

 appear to attain the size which it does in Central India, for none of the 

 specimens from the former country are above 5 J inches, the tail being generally 

 more than twice the length of the body. The claws on fingers and toes are 

 always black. The tympanum is usually covered by a yellowish hardened 

 shield. 



Jerdon (Proc. Asiat. Soc. Beng., Feb. 1870, p. 76) is, I think, correct 

 in retaining the name Ponticeriana, for the smaller Sitana with long limbs, 

 but I doiibt that the larger form, for which he proposes the name Deccanen- 

 sis, is really specifically distinct from Ponticeriana. I collected hundreds of 

 them, in all sizes from 3 to 8 inches ; they are all of the same type, as those 

 I received from Ceylon and from South India, and I find the fore limb 

 scarcely ever reaches the vent, while the hind-limb extends usually beyond 

 the snout, except in a few full grown specimens. 



Chaeasia, Okiocalotes and Oriotiakis. 



The name Cliarasia has been proposed by Gray (Lizards Brit. Mus., 

 1845, p. 216) for the South Indian species, Ch. dorsalis, as type. I have 

 examined numerous well preserved specimens of this and of another species 

 inhabiting the greater portion of Central, and perhaps also of Northern, 

 India, and tins induces me to propose a somewhat different definition of the 

 genus. 



Char. Body elongate, somewhat depressed, covered with imbricate, 

 or subimbricate, keeled scales, between which some slightly larger ones are 

 intermixed, the scales being arranged in more or less indistinct transverse 

 series ; those on the lower side are often less distinctly keeled than those 

 on the back ; tympanum naked ; a small tubercular spine at the posterior 

 end of the supraciliary edge ; some spines above the tympanum ; nuchal 

 and dorsal crest present, but low ; (generally) a fold across the throat ; scales 

 on the tail subimbricate, not arranged in regular cross series ; (no distinct 

 gular sac, no femoral, or preanal pores). 



Cliarasia must be classed next to Trapelus, to which it is very nearly allied. 



Sab. — Terrestrial, generally found between blocks of gneissose rocks. 



The distinctive points in the structure of Cliarasia are : — 1st, the 

 presence of a small tubercular spine on the hinder supraciliary edge ; 2nd, 

 the presence of some slightly larger scales intermixed between the smaller 

 ones at the side of the body. It is true that these larger scales are very 

 difficult to trace in Cli. dorsalis, but I have observed them in various young 

 and old specimens. Were it not that they are, as a rule, better developed
