1904.] LACERTA DEPRESSA OF CAMERANO, 337 



L. depressa in the British Maseum Catalogue of Lizards*. Should 

 Camerano's species be broken up into several forms, this specimen 

 must be regarded as tlie restricted type of L. depressa. It is pro- 

 Ijably from Trebizond, since Boettger's specimens from that locality 

 agi-ee closely with it t ; but it must be noted that specimens from 

 Hhusha, E. Kai-abagh, received from the Senckenberg Museum 

 MS L. muralis, var. defilipjni BoettgerJ, belong, in my opinion, 

 to the same variety. Mehely's var. depressa from 8hion in Trans- 

 caucasia § is also probably the same thing. 



The second specimen, with larger dorsal scales (51 across the 

 body), with larger and more strongly keeled scales on the tibia, 

 with more strongly raised keels on the caudal scales, and with 18 

 femoral pores, has been specially selected by Bedriaga as the type 

 of var. rudis. But it is remarkable that no allusion should have 

 been made to its having five anterior labials instead of four, the 

 number unreservedly given in the diagnosis of L. depressa. The 

 specimen from Batoum noticed by Boettger I; is probably coiTectl}^ 

 referi'ed to this form ; it has 5 anterior labials on one side, 4 on 

 the other, and 46 scales aci'oss the body. 



The third specimen answers in all important respects to the 

 figure of L. portschinskii of Kessler ^, from Tiflis, the Russian 

 description of which was ti"anslated in 1879 by Bedriaga**. 

 Bedriaga then identified L.portschinsJcii with L. d,epressa ; he after- 

 wards in his monogi-aph published in 1885, most emphatically 

 repudiated this identification and placed L. pjortscJdnshli simply 

 in the synonymy of his L. muralis fusca, whilst regarding 

 L. depressa as a distinct species having much less in common with 

 L. muralis than with L. oxyce2)hala ff . 



The foui-th specimen agi-ees entirely with the Persian lizards 

 described by De Filippi and by Blanford, and may be referred to 

 the var. defilippii Camerano, of Avhich var. persica Bedriaga, is a 

 synonym. 



The fifth specimen, as stated above, should be referred to the 

 var. depressa, sensu stricto. 



Comparing the L. djcpressa of Werner with these specimens, I 

 find it does not agree with any of them, difiering in the shorter 

 limbs, a character emphasised by Werner in his description. 

 But it agrees with specimens from. Lake Gokcha which, in my 

 opinion, represent the L, chalyhdjea of Eichwald (Z. muralis, Tar. 

 saxicola Bedriaga). In the following table I give the measure-

 8 tibial scales corresponding to 9 orlO dorsals. 



X L. c. p. 144. These Shusha specimens are regarded by Boettger as connecting 

 the var. defilippii Camer. with the var. raddii Boettg.

ft The British Museum possesses a quite similar specimen from Elizabethpol, 

 among several received from the St. Petersburg Museum, the largest of which agrees 

 with Eversmann's figure of L. saxicola.
