ALLIED TO LACERTA MURALIS. 81 



Particulars of Specimens examined. 



Ilahitat. Mountains of Dalmatia, Herzegovina, and Montenegro, between 700 and 

 1400 m. altitude. 



Lacerta nwsorensis, in general appearance, occupies an intermediate position between 

 L. mnralis (especially such mountain-forms as vars. monticola, horvathi, and chahjhdea) 

 and L. oxijcephala. Well distinguished among all other species by the large rugose 

 scales on tlie upper surface of tlie tibia, and from tlie two above-named by the larger 

 dorsal scales compared with the laterals. Its real affinities are doubtful and it may well 

 be that its resemblance to L. oxycephala is a case of parallelism, both species being 

 independently derived from some more generalized type akin to L. hrandtii.

Form and general proportions much as in tlie typical L. muralis. Head 1^ to If 

 times as long as broad, its depth, in the tympanic region, equal to the distance between 

 the anterior corner or the centre of the eye and tlie anterior border of the tympanum; 

 snout pointed *, rarely rather obtuse, as long as postocular part of head ; cheeks more 

 or less swollen in the male ; length of pileus If to 2 times its width. Neck at least 

 as broad as head ; body rather strongly depressed. Hind limb reaching tiie axil, 

 the shoulder, or the collar in the male, the wrist or the axil in the female. Foot 

 usually longer than the head, as long as the head in very large specimens. Tail 

 cylindrical or depressed at the base (elliptic in section) li to 2 times as long as head 

 and body. 



* Particularly in specimens from Porto Santo.
