VARIETIES OF THE WALL-LIZARD. 187 
middle of body, caudals often rather pointed behind. 17 to 25 gular scales. Femoral 
pores 12 to17. From snout to vent up to 60 mm. Caucasus. 
And, finally, 
G. Var. hieroglyphica Berthold, with 68 to 71 scales across the body, 21 to 26 femoral pores, 
30 to 35 scales under the fourth toe, and reaching a length of 65 mm. from snout to vent, 
is very closely related to the var. serpa, to which it has been referred by Werner, thus 
standing quite apart from the preceding forms. 
So far as I have been able to ascertain, Z. muralis does not extend into Syria, the 
specimens so named by Giinther, Lortet, and others, belonging to L. lewvis Gray.

pl. xxi. fig. 7, and p. 549, pl. xxi. fig. 8. 
This name, which has priority over that of saaicola, a fact overlooked by Méhely, 
was applied to a specimen described and figured in 1841 (“ E fusco violacea, eneo- 
nitens, maculis nigris exiguis adspersa, lateribus obscurius fusco-fasciatus, nigro- 
maculatis, scuta abdominis exteriora chalybdeata”) ; the figure shows a stout form with 
short limbs (foot not longer than head) and a series of round light spots on the upper 
border of the dark lateral band. ‘The number of femoral pores is “ circiter 16.” In 
all respects the description and figure agree with specimens from lelenovka, Lake 
Gokscha, 2000 m. altitude, received by the British Museum from the St. Petersburg 
Museum in 1886, and which are unquestionably identical with Werner’s L. depressa, 
from the Bithynian Olympus, near Brussa, 1800 m., as I pointed out in 1884, and as 
the figures 1 & 2 on Pl. XXII. ought to show, as well as with specimens from Kavkaz, 
L. Gokscha, which I owe to the kindness of Dr. V. Vavra. Méhely has demurred to 
this identification and proposed the name bithynica for Werner’s lizard, of which he 
has examined three specimens from Brussa, in the Werner Collection, and one from 
Amasia, in the Hungarian Museum. 
Méhely identifies Eichwald’s L. chalybdea with Kessler’s L. portschinskii, which is 
a more slender lizard, with longer foot, with more numerous femoral pores, etc. 
Nikolsky * has recently pointed out the error of Méhely, and also the fact that he has 
* Ann. Mus. Zool. Ac. St. Pétersb. xv. 1910, p. 493. I am grateful to my friend Dr. de Bedriaga for a 
translation of Nikolsky’s paper, published in Russian.
