LACERTA MURALIS IN WESTERN EUROPE AND NORTH AFRICA. 371 
Dorsal scales (Pl. XXVI. fig. 14) granular, roundish-hexagonal, more or less feebly 
but always distinctly keeled, 55 to 68 across the middle of the body; 3 and 4 trans- 
verse series (rarely 4 throughout) correspond to one ventral plate, 35 to 47 to the length 
of the head. 
Ventral plates in 6 longitudinal and from 26 to 30 transverse series. 
Anal plate bordered by one or two semicircles of small plates. 
Scales on upper surface of tibia finely granular, much smaller than dorsals, more or 
less distinctly keeled. 19 to 24 pores under each thigh. 26 to 31 lamellar scales 
under the fourth toe. 
Upper caudal scales strongly keeled, truncate or very obtusely pointed behind ; the 
whorls subequal in length, the fourth behind the postanal granules containing 30 to 38 
scales. 
Brown, yellow, or green above, with black or reddish-brown spots or vermiculations, 
usually arranged in five or seven more or less well-defined longitudinal stripes; the 
black markings sometimes forming chains enclosing roundish light spots, or an irregular 
reticulate pattern, or reduced to mere dots or vermiculations ; females often with a light 
dorso-lateral streak, beginning from the supraciliary edge, sometimes bordered by fine 
black lines, sometimes with a black vertebral streak ; upper surface of head spotted or 
vermiculated with black; tail with dark and light markings, forming more or less 
regular longitudinal series. Young with six light streaks on the body. Belly yellow, 
orange, or red, without markings, except on the outer row of ventral plates, which 
bears large blue spots.
