VARIETIES OF THE WALL-LIZAED. 167 



This lizard is known only from S.AV. Croatia (Kapela and Velebit ranges), where it 

 inhabits wooded districts between 600 and 1100 metres altitude, often in company 

 with the typical form of L. muralis and L. vivipara. 



It bears some resemblance to L. moso7'ensis Kolomb. ; in his original description 

 (1904) Mehely regarded it as directly derived from that species (pp. 374 & 375), and 

 in a somewhat later contribution (1905, p. 315) he is very positive about it: "So ist 

 Lacerta horvathi nachweisbar der Abkommling der dalraatinisch-hercegowinischen 

 Lacerta mosorensis." At that time I pointed out (Tr. 1905, pp. 365-367, figs.) the 

 agreement in many respects of L. horvathi with the Spanish-Portuguese var. monticola 

 and the Asiatic vars. saxicola, chalyldea, and depressa. In Mehely 's latest account 

 (1909, p. 614) nothing more is said of the derivation of L. horvathi from. L. mosorensis, 

 but the former is held to be descended from L. saxicola typica : " Demgemass kann 

 Lacerta Horvathi, trotz ihrem scheinbar primitiveren Schadelbau sehr wohl von 

 Lacerta saxicola typ. abgeleitet werden, mit welcher Art sie auch durch unverk- 

 ennbare Beziehungen des Schuppenkleides und des Schadelbaues auf des Innigste 

 verbunden ist. Lacerta Horvathi steht in jeder Beziehung auch zu L. saxicola 

 armeniaca, so nahe, dass sie eventuell fiir eine etwas veranderte Form derselben 

 betrachtet werden konnte, dennoch konnen diese beiden Formen miteinander 

 naturgemass nicht verbunden werden und miissen fiir parallele Entwickelungsformeti 

 gelten, die beide aus Lacerta saxicola typ. hervorgegangen und vielleicht in ahnlich 

 beschafFenen Gegenden, zufolge der Einwirkung ahnlicher klimatischer Verhaltnisse 

 oder einer ahnlichen Lebensweise zustande gekommen sind." Except for the 

 derivation from L. saxicola, which Prof. Mehely may perhaps entirely abandon in 

 his next attempt at the " Losung der Muralis-Frage," I entirely agree with the above 

 statement, and in view of the state of things in the Spanish-Portuguese vars. hocagii 

 and monticola, it is needless to say that I can only regard L. horvathi as one of the 

 numerous forms or varieties of L. muralis. 



Two of the specimens received from Prof. Mehely are figured on PL XX, 

 figs. 1 & 2.
