112 F. Stoliczka — On Indian Lizards. [No. 1, 



middle of the body in a considerably smaller number, there being 130-140 

 series of squarish scales in Charasia dorsalis, while there are only 80-100 

 sub-imbricate ones in Blanfordana. Also, the nnchal crest is much better 

 developed in the latter than in the former species. 



Ch. Blanfordana is given by Mr. Blanford from a large number of 

 localities in Central India. I found it not uncommon on the gneissose rocks 

 composing the Parisnath hill, in "Western Bengal ; it is a true rock lizard, as 

 noted by Mr. Blanford, who describes (loc. cit.) its habits at some length. 



It is also very likely the species noticed by Blyth on one or two 

 occasions from Birbhum, and also, I think, from the Panjab, under the name 

 of Ch. dorsalis. Anderson in Proc. Zool. Soc. Lond., 1871, p. 168, repeated 

 Blanford's incorrect identification of the present species, without, however, 

 acknowledging the source he took it from. 



Chakasia (Oriotiaris) tricarestata, Blyth. 



This species was originally described by Blyth as Oalotes triearinatus 

 (J. A. S. B., xxxi, p. 650), and afterwards by Giinther as Tiaris JElliotti, 

 subsequently made the type of a distinct genus under the name Oriotiaris ; 

 (Kept, of India, p. 150, and Jerdon in Proc. A. S. B., Feb. 1870, p. 77, and 

 Anderson, in Proc. Zool. Soc, 1871, p. 167. 



I have already noted the great similarity of the generic characters of 

 this species to typical Charasia. 



Blyth's name ' triearinatus'' refers to the presence of three keels 

 on the anterior part of the body, there being besides the median 

 crest a row of larger scales on each side of it, disappearing towards 

 the middle of the body, but becoming again better traceable on the 

 femoral region. The large spiny tubercles above the tympanum are 

 always multicarinate on the upper side, and often bluish during life. The 

 colour of the live lizard is generally bright grass green above, with the 

 angular series of larger scales (directed backwards) often chocolate brown ; 

 the lateral keels on the neck are yellowish, sometimes margined with a 

 dark line below. The sides of the body are either entirely green, with only 

 two brown streaks above and below from the eye, or the sides of the head, 

 tympanoid region, neck and anterior part of belly, are deep chocolate brown. 

 There are, however, always some light yellow or whitish spots on the labials, 

 and generally a yellowish streak at the base of the neck on each side. Lower 

 side yellowish white. In spirit the green colours gradually change to more 

 or less distinct brown. 



As noticed by Jerdon, the species is by no means common about 

 Darjiling ; I found it between 3000 and 8000 feet, generally about large 

 stones in sunny places on the scarp of the road. The largest specimen 

 does not exceed 7 inches.
