VARIETIES OF THE WALL-LIZARD. 163 
and the collar-edge is entire, characters which distinguish, though not sharply, the 
typical form from the following variety. 
Some males (Bosnia, Bulgaria) are greyish brown above, with black spots or vermi- 
culations on the back, blackish brown on the sides, with light, black-edged round 
spots, the larger of which form a regular dorso-lateral series, a pattern of 
coloration which can be exactly matched by some Caucasian specimens, in which, 
contrary to Méhely’s statement, the head is not in any way flatter than in some of the 
Bosnian lizards. These males have the lower parts more or less spotted with black, 
occasionally to such an extent as to appear black with numerous small white spots 
(Pl. XVI. fig. 6). Some males, and all females examined, have a black vertebral 
streak or series of spots (Pl. XVI. fig. 7). The lower parts are unspotted in females, 
and appear to have been white; they were salmon-pink in a recently preserved male 
from Panagiuriste, Bulgaria. According to Werner (1891), the Istrian specimens 
examined by him have the under parts white in both sexes, whilst males from 
Herzegovina have these parts red (1899).

(Albania). According to Tomasini, Wiss. Mitth. Bosn. Herz. ii, 1894, p. 570, this is 
the only form of Z. muwralis found in Bosnia. 
Bedriaga * reports the typical form from various parts of Greece, and alludes to 
specimens with fire-red belly from the neighbourhood of Athens. ‘The only specimen 
I have seen is from Lake Stymphalos, Northern Morea, presented by Mr. Norman 
Douglass, particulars of which are given in the above table. I may add that this 
specimen is rather above the average size, as may be seen from the following 
measurements, that the head-shields are absolutely typical, the dorsal scales ovai- 
hexagonal, distinctly keeled, and larger than those on the flanks, the caudal scales 
truncate and moderately keeled, forming alternately longer and shorter whorls. ‘The 
hind limb reaches the shoulder. Reddish grey above, with an interrupted vertebral 
series of dark spots and a lateral series of large dark reddish-brown spots, forming a 
chain and confluent with a band on the head and neck; lower parts with small black 
spots (Pl. XVI. fig. 5).
