VAEIETIES OF THE WALL-LIZAED. 155 



type specimen, and tbe lamellae 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 

 Ij. sardoa, the antero-lateral borders being convex instead of straight or concave. 

 But 1 cannot agree with him as to the importance of this character, since I find the 

 same condition in two specimens of the var. bedriagce, and I have observed many 

 similar cases in the typical L. muralis and in the vars. quadrilineaia, serpa, and others. 

 1 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. serjja 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. Mehely * 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. 1905, pi. xxvii. 

 fig. 7 and xxviii. fig. 4, as well as others from the same localities, belong to the 

 var. serpa, whilst those from Messina (pi. xxvii. fig. 6), Syracuse, Modica, and some 

 from Catania, should be referred to the var. tiliguerta. 1 must, nevertheless, point 

 out that I am not always able to distinguish examples of the vars. tiliguerta and serpa, 

 so completely do they merge into each other, and the Eastern 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 o3) 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
