Lacerta. 



323 



B. Uuiform black or blackish. 



Columns as on p. 318. 



Habitat. — Dalmatia, Herzegovina, Montenegro, and neighbouring 

 islands ; the reticulated form from sea-level to 1000 m. altitude, the 

 black form from 500 to 1400 m. 



Distinguished from L. muralis by the two postnasals, the much 

 enlarged basal subcaudal scales, and the frequent separation of the 

 prefrontal from the second supraocular, this lizard bears considerable 

 resemblance to L. muralis, var. hedriagse, but I regard this as a case 

 of convergence, such as we know, within the limits of the species 

 L. muralis, in the vars. monticola, horvathi, and saxicola. The real 

 affinities are with L. danfordii, and both species were probably derived 

 from the same ancestor.
