LACERTA MURALIS IN WESTERN EUROPE AND NORTH AFRICA. 407 
Scales on upper surface of tibia as large as or a little smaller than dorsals, keeled ; 
18 to 28 femoral pores on each side, usually 21 to 25; 27 to 34 lamellar scales under 
the fourth toe, usually 30 to 33. 
Caudal scales truncate, upper rather strongly keeled, 30 to 37 in the fourth whorl 
behind the postanal granules. 
Brown, olive, or green above, usually spotted or marbled with blackish and with a 
yellowish or whitish dorso-lateral streak or series of spots; frequently a blackish 
vertebral streak or series of spots; sides, in males, usually blackish, with numerous 
round light spots; females frequently uniform yellowish brown or mahogany-brown on 
the back, with a yellowish, black-edged dorso-lateral streak from the eye to the tail, 
and another, wider, light streak from the ear to the groin (Pl. XXIX. fig. 2); limbs 
with round, dark-edged, light spots. Lower parts white or yellow, without or with black 
spots, which are usually confined to the throat and the outer row of ventral plates. 
According to Lorenz Miiller, the lower parts are sometimes bright orange in males. 
The following notes are taken from living specimens from Sardinia, for which I am 
indebted to Count Peracca, and three of which are figured (Pl. XXIII. fic, 4, & 
ET; XGXTX. fies. 1, 4): 
Coppery brown, yellowish brown, greenish yellow, or bright green above ; white, with 
mother-of-pearl sheen, or greenish yellow beneath ; turquoise-blue spots always present 
above shoulder and on outer ventral plates ; some specimens with numerous blue spots 
on the sides, alternating with green or greenish-yellow ones; the dorso-lateral streak 
pale brownish or greenish yellow. 
Specimens in which the black markings preponderate, the light ground-colour 
appearing as four dorsal lines with small spots or cross-lines between them, have been 
named by Bedriaga var. corsica (P]. XXIX. fig. 3).
