VARIETIES OF THE WALL-LIZARD. 167 
This lizard is known only from S.W. 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 ZL. mosorensis Kolomb.; in his original description 
(1904) Méhely 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 Abkémmling der dalmatinisch-hercegowinischen 
Lacerta mosorensis.” At that time I pointed out (Tr. 1905, pp. 365-367, figs.) the 
agreement in many respects of LZ. horvathi with the Spanish-Portuguese var. monticola 
and the Asiatic vars. saxicola, chalybdea, and depressa. In Méhely’s latest account 
(1909, p. 614) nothing more is said of the derivation of LZ. 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 kénnte, dennoch kénnen diese beiden Formen miteinander 
naturgemiiss nicht verbunden werden und miissen fur parallele Entwickelungsformen 
gelten, die beide aus Lacerta saxicola typ. hervorgegangen und vielleicht in ahnlich 
beschaffenen Gegenden, zufolge der Einwirkung ahnlicher klimatischer Verhaltnisse 
oder einer dhnlichen Lebensweise zustande gekommen sind.’ Except for the 
derivation from ZL. saaicola, which Prof. Méhely may perhaps entirely abandon in 
his next attempt at the “ Lésung der Muralis-Frage,” I entirely agree with the above 
statement, and in view of the state of things in the Spanish-Portuguese vars. bocagit 
and monticola, it is needless to say that I can only regard L. horvathi as one of the 
numerous forms or varieties of LZ. muralis. 
Two of the specimens received from Prof. Méhely are figured on Pl. XX.
