VAEIETIES OF THE WALL-LIZAED. 187 



middle of body, caudals often rather pointed behind. 17 to 25 gular scales. Femoral 

 pores 12 to 17. Prom snout to vent up to 60 mm. Caucasus. 

 And, finally, 

 Gr. Var. hieroghjpMca Berthold, ^vith 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. sei-pa, 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, L. muralis does not extend into Syria, the 

 specimens so named by Giinther, Lortet, and others, belonging to L. Icevis Gray.

Tliis name, which has priority over that of saxicola, a fact overlooked by Mehely, 

 was applied to a specimen described and figured in 18il {" E fusco violacea, oeneo- 

 nitens, maculis nigris exiguis adspersa, laterihus ohscurius 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, ISOO 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. Mehely 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. 



Mehely 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 Mehely, and also the fact that he has

 translation of Nikolsky "s paper, published in Eussian.
