VARIETIES OF THE WALL-LIZARD. 183 
Collar not serrated, with 9 to 11 plates, which may be very small; gular fold very 
distinct ; 28 to 35 scales and granules between the symphysis of the chin-shields 
and the median collar-plates. 
Dorsal scales small, granular, round or oval, smooth, rarely faintly keeled, equal in 
size, 54 to 63 across the middle of the body; 3 and 4 series corresponding to one 
ventral plate, 38 to 56 to the length of the head. 
Ventral plates in 6 longitudinal and 26 to 34 transverse series. Preanal plate 
moderate, with one or two semicircles of small plates. 
Scales on upper surface of tibia feebly keeled, considerably smaller than dorsals. 
18 to 26 femoral pores on each side (usually 21-24). 26 to 33 lamellar scales under 
the fourth toe. 
Upper caudal scales truncate and very obtusely, very feebly, diagonally keeled ; 
28 to 38 scales in the fourth whorl behind the postanal granules. 
Specimens identical in form and scaling differ very considerably in the coloration. 
The form which has been referred to L. muralis fusca * is brown or grey above, 
with small black spots, which may form two or three longitudinal series on the back 
and reticulations on the side, the back being separated from the side by a streak of 
the light ground colour; some specimens with very small dark dots, or nearly uniform ; 
no very distinct markings on the tail; lower parts whitish, unspotted. The largest 
specimen measures 67 mm. from snout to vent. 
In the var. milensis Bedriaga ¢ the upper parts are pale brown, the sides yellow or 
greenish yellow, with black marblings often forming cross-bars ; blue ocelli above the 
shoulder. Belly bluish, with or without large black spots; throat often black with 
round light spots (Pl. XXI. fig. 3). Werner's var. nigrogularis, also from Milos, 
differs in having a black vertebral stripe or series of spots. From snout to vent 
57 mm. 
Bright green specimens (Pl. XXI. figs. | & 2), with the markings as in the 
specimens described first, and with or without a black vertebral stripe, have been 
referred by Bedriaga to L. muralis neapolitana {. Belly white or orange. 
The largest specimen measures 71 mm. from snout to vent. 
Bedriaga observes that specimens from Tenos, Syra, and Phanar are green on the 
anterior part of the back, or only on the neck, and grey-brown or greyish green on the 
rest of the back. In all these colour-variations, large blue or blue-green spots are 
present on the outer row of ventrals. 
* Also var. naxensis Werner. The specimens before me are from Petali (Bedriaga), Tenos (Bedriaga), 
and Naxos (Werner). These specimens often bear a strong superficial resemblance to lizards of the 
yar. quadrilineata from Corsica. 
+ Type specimens of vars, milensis and nigrogularis from Milos and Erimomilo are preserved in the British 
Museum. 
+ Specimens from Syra, Mykonos, and Santorini have been received from Herr L, Miiller.
