GEOGRAPHICAL DISTRIBUTION. 
This form occurs in Spain, from where Seoane mentions it as 
«Comunisima en toda Galicia». (13, p. 18.). Boulenger (4, p. 361—362.) 
records some individuals from Asturias between Galicia and León, from 
Pontevedra, from the Lozoya Valley 1 near Madrid, and from Escorial. 2 
In Portugal Oporto, Lisbon, Alcochête, the Serra de Gerez, Cintra and 
Coimbra are stated up to now as being inhabited by the form in question. 
I think that some of the localities mentioned by de B. Ferreira (7, p. 
10—11.) regarding « Lacerta muralis var. fusca Bedr.» (= Lac. muralis 
1 Boulenger (5, p. 144.) mentions a «Loroya Valley»; a Valley of this name being 
to me unknown, there seems to be an error, Boulenger most likely referring to the Lozoya 
Valley near Madrid. 
2 Its geographical distribution appears to be somewhat more extended than could 
be understood from Schreiber’ s (11, p. 428.) description according to which var. Bocagei 
would be limited : «. . auf den Westen des Festlandes, namentlich auf Portugal und Ga¬ 
lizien».
