S. microlepis are smaller througliont. On tEe whole, the present species approaches S. can- 
casicus more nearly than any other form with which I am acqnainted. 
I have no specimen of Stellio aralensis^ for comparison, and from its inhabiting the steppes 
east of the Sea of Aral, it may very possibly he nearly allied to the present species. Accord¬ 
ing to Lichtenstein’s description,it has the hack scales strongly keeled and mucronate, and the 
toes fringed, the colouration is very different from that of S. stoUczkaims, being ash-grey, with 
pale wavy crosshands, the tail and limbs being also banded, and there is a large black spot at 
each side of the neck in the fold. The young have this spot peculiarly distinct and have 
long pale spots on the back on a bluish-grey ground. There can be but httle doubt of the 
present being a distinct species. A form from Western Tm’kestan appears to have been 
named L. lehmanni by Strauch,^but I can find no description of it. In the list of Western 
Turkestan reptiles, “ S. Mmalayanus^ Strauch,” is also included by Severtzoff.

I feel convinced that there must be some mistake in uniting the Phrynocephalus of 
Western Tibet with Lacerta ccmdivolmila of Pallas.^ In the first place, Pallas’ description, 
L. corporis sqiiamis mimitissimis Iccrihus, cemda longiuscula Icsvissima, suhtus apice ruhro 
nigroque variegata, does not appear to agree well. The tail in the Tibet IPlirynoceplialus is 
not nearly so long as would be inferred from the above description and from the measurements 
of L. caudivolvula by Pallas,—whole length 3 inches 3 fines, tail 2inches, so that the proportion of 
the head and body to the tail is 5 to 8. In a large number of specimens from Tibet and Eastern 
Turkestan I find the proportions of the head and body to the tail vary between 5 to 5*6 and 
6 to 6'3, the last being exceptional. The tail, moreover, can scarcely be called very smooth; 
the scales towards the extremity, as a rule, are keeled. Then the colouration is different, and 
especially that of the tail, which is said by Pallas, in his more detailed description, to be suhtus 
a medio ad apicem interrupte nigra et rubra. The colouration in P. theohaldi is extremely 
variable, as noticed by Steindachner in his description (of P. stoliczkce), but I have never seen
