VARIETIES OF THE WALL-LIZARD. 155 
type specimen, and the lamellx under the fourth toe from 26 to 29. Two specimens 
have 8 longitudinal rows of ventrals. 
Peracca also points to the shape of the frontal shield as a distinctive feature of 
L. sardoa, the antero-lateral borders being convex instead of straight or concave. 
But I cannot agree with him as to the importance of this character, since I find the 
same condition in two specimens of the var. bedriagv, and I have observed many 
similar cases in the typical LZ. muralis and in the vars. guadrilineata, serpa, and others. 
I have seen specimens in which the antero-lateral border of the frontal is concave on 
one side and convex on the other, this being particularly marked in a specimen of the 
var. serpa from Spalato, Dalmatia, preserved in Dr. Werner's Collection. 
V.—SICILY (Supplement). 
In my previous paper I referred all the specimens that had come under my notice 
to the var. serpa. With a more extensive material before me, I find that both 
the vars. serpa (or sicula) and tiliguerta occur in Sicily. Prof. Méhely * was therefore 
perfectly right in referring Sicilian specimens to the latter form, and I was wrong in 
throwing doubts on the correctness of his identification. I apologise to him for having 
done so. The specimens from Palermo and Catania, figured in Tr. 1900, pl. xxvii. 
fig. 7 and xxviii. fig. 4, as well as others from the same localities, belong to the 
var. serpa, whilst those from Messina (pl. xxvii. fig. 6), Syracuse, Modica, and some 
from Catania, should be referred to the var. ¢iliguerta. I must, nevertheless, point 
out that I am not always able to distinguish examples of the vars. ti/iquerta and serpa, 
so completely do they merge into each other, and the Hastern var. hieroglyphica 
(p. 201) further adds to the difficulty. 
Var. SERPA. 
I append particulars of specimens collected by Prof. O. Neumann on Monte Cuccio, 
near Palermo, and from Palermo in Dr. Werner’s Collection. It will be seen that they 
have, on an average, a lower number of scales across the body (50 to 67), fewer femoral 
pores (18 to 23), and fewer subdigital scales (28 to 33) than in the series referred to 
var. tiliguerta (scales 62-79, pores 21-28, subdigital scales 30-35). Further, the 
head is shorter and more convex, the parietal shield is always in contact with the 
upper postocular, the dorsal scales are more distinctly keeled, and the coloration is 
different. Some specimens are bright green above, with black spots forming 
longitudinal series, others are brown with or without spots, and with two whitish 
lines along each side. ‘The belly is white, orange, or brick-red in males, white or
