VARIETIES OF THE WALL-LIZARD. 169 
Body not much depressed. The hind limb reaches the axil or the shoulder in males, 
the wrist or the elbow of the adpressed fore limb in females ; foot a little longer than 
head (up to once and one fourth). 
Tail rounded, once and three-fifths to twice and one-fifth length of head and body. 
Rostral shield usually entering the nostril or narrowly separated from it *; nasals 
forming a suture behind the rostral; a single postnasal + ; frontal as long as or a little 
shorter than its distance from the end of the snout; a series of granules between the supra- 
ciliaries and the two principal supraoculars, the anterior of which is usually in contact 
with the first, or with the first and second supraciliaries ; parietals once and one-fifth to 
once and a half as long as broad, nearly always in contact with the upper postocular ¢ ; 
occipital very variable, usually shorter than and as broad as the interparietal, some- 
times narrower, sometimes broader§; temporal scales sometimes as small as in a 
typical Z. muralis, sometimes nearly as large as in a typical 1. tawrica, usually as in 
var. campestris; tympanic shield always distinct, and the masseteric usually so, the 
latter frequently in contact with the supratemporal, or separated from it by a single 
series of scales; four || upper labials anterior to the subocular, the lower border of 
which is much shorter than the upper. 
Collar-edge feebly but more or less distinctly serrated ; 7 to 11 plates in the collar; 
gular fold very distinct ; 20 to 28 scales and granules between the symphysis of the 
chin-shields and the median collar-plate. 
Scales on the back oval-hexagonal or distinctly hexagonal, distinctly or sharply 
keeled, often smaller on the vertebral line; lateral scales as large as or a little larger 
than the dorso-laterals, usually more or less distinctly keeled § ; 44 to 57 (usually 48 
* Exceptions in a ¢ from Goritz (Schreiber) in Lataste Coll., and in a ¢ from Brestica, Herzegovina 
(Werner). 
+ Two superposed postnasals on one side in a ¢ from Scoglio Supetar (Werner Coll.). 
+ Exception in a 2 from Solta, in one from Gelsa, and in one from Cettinje (Werner Collection); Klaptoez 
(J. c.) also records an exception in a specimen from Albania. 
§ Inag from Brestica, Herzegovina (Werner), the occipital is as long and twice as broad as the interparietal, 
whilst in a Q accompanying it the former shield is barely half as long and half as broad as the latter. A 
small shield is sometimes intercalated between the interparietal and the occipital; in a ¢ from Bukovici, 
the parietals meet in a short suture between these two shields; the three specimens from the Karst 
(Schreiber) in the Lataste Collection have a short transverse cleft in the parietal on each side of the 
interparietal, 
|| Three on one side in single specimens from Trieste (Werner), Bosnia (Floericke), Trebinje (Werner), and 
Zara (Spada Novak). Not one of the many specimens examined by me has five, a number which is sometimes 
found in specimens from Lagosta, and in as many as 10 per cent. of those from Melisello. 
{| Lehrs (J. c. p. 231) says “ Riicken- und Flankenschuppen gleich gross, bis za den Bauchschildern deutlich 
gekielt.” There is no constancy in this character. In a female from Dalmatia (Spada Novak), of uniform olive 
coloration, the scales on the lower part of the flanks are considerably larger than the dorsals, and perfectly 
smooth. In various striated specimens, including the actual types from Fiume, I also find the lateral scales 
distinctly larger than the dorsals, and the keels often so faint as to be difficult to detect.
