SECOND YARKAND MISSION. 
S. microlepis are smaller throughout. On the whole, the present species approaches S. cat 
casicus more nearly than any other form with which I am acquainted. 
I have no specimen of Stellio aralensis 1 for comparison, and from its inhabiting the s e Pl " 
east of the Sea of Aral, it may very possibly he nearly allied to the present species. Ac 
ing to Lichtenstein’s description, it has the hack scales strongly keeled and mucronate, anc ^ 
toes fringed, the colouration is very different from that of S. stolicsfcanus, being ash-grey, n 
pale wavy crosshands, the tail and limbs being also banded, and there is a large black 
each side of the neck in the fold. The young have this spot peculiarly distinct anc ^ ^ 
long pale spots on the hack on a bluish-grey ground. There can be but little clouht °’ ^ 
present being a distinct species. A form from Western Turkestan appears to ha\c^^ 
named L. lehmanni by Strauch, 2 hut I can find no description of it. In the list of eS 
Turkestan reptiles, “ S'. himalayanus , Strauch,” is also included by Severtzoff.

I feel convinced that there must he some mistake in uniting the Phrynocepbp ,

not nearly so long as would he inferred from the above description and from the nieasi^.^ of 
of L. caudivolmila by Pallas, — whole length 8 inches 3 lines, tail 2 inches, so that the p r0 P j, as tem 
the head and hotly to the tail is 5 to 8. In a large number of specimens from Tibet an an d 
Turkestan I find the proportions of the head and body to the tail vary between 5 0 ^ o0 tp ; 
5 to 6 - 3, the last being exceptional. The tail, moreover, can scarcely he called veiy , aI1 d
