broader than the posterior part of the frontal ; 5 or 6 (rarely 4) superciliaries, first 

 or second usually longest, the suture between the first and second usually oblique, 

 sometimes vertical. 



Rostral largely entering the nostril ; postnasal single * ; first loreal much shorter 

 than second. 4 or 5 upper labials anterior to the subocular f , the lower border 

 of which is much shorter than the upper. Usually rather large, irregular shields 

 cover the temple, often as in an average L. a(//lis ; sometimes the temporal lepidosis 

 is as small as in an average L. muralis ; a more or less distinct masseteric shield ; 

 tympanic shield distinct, sometimes small ; a more or less enlarged upper temporal 

 anteriorly, followed by 3 or 4 smaller shields. 



Pterygoid teeth strongly developed. 



1^8 to 34 scales and granules in a straight line between the symphysis of the chin- 

 shields and the median collar-plate ; gular fold distinct. Collar with even edge, 

 composed of 9 to 12 plates J. 



Scales on back juxtaposed, granular, round, suboval, or subhexagonal, smooth or 

 feebly or faintly keeled, on flanks towards the ventrals larger, flat and subimbricate, 

 smooth ; 58 to 65 scales across the middle of the body ; 2 and 3 or 3 and 4 transverse 

 series, on the sides, corresponding to a ventral plate, 48 to 60 in the middle of the back 

 corresponding to the length of the head. Ventral plates in 6 longitudinal series, 

 subequal or the second series from the middle line the broadest; 28 to 33 transverse 

 series (28 to 30 in males, 31 to 33 in females). 



Praeanal plate rather large, with 2 or 3 semicircles of small shields or scales. 



Scales on upper surface of tibia as large as or a little smaller than dorsals, distinctly 

 keeled. 26 to 31 lamellar scales under the fourth toe. 20 to 26 femoral pores on 

 each side. 



t!audal scales truncate or very obtusely pointed behind, the upper narrow and slightly 

 oblique, or rather broad and more oblique, more or less strongly keeled, the whorls 

 subequal in length ; 28 to 38 scales in the fourth or fifth whorl behind the postanal 

 granules. 



The coloration varies much according to individuals. Females and young are 

 beautifully striped with dark brown or black, some specimens may even be described as 

 black above with 5 or 6 light longitudinal streaks or even 7 in front (5 on the nape, 

 as in Acanthodactylus vulgaris). The adult female (PI. III. fig. 9) may be of a reddish 

 brown, with two broad blackish bands along each side, the outer proceeding from the 

 eye ; these bands bordered above and below by a narrow white streak and separated 

 from each other by a third light streak (proceeding from the superciliary edge), whicli 

 is pale yellow or pale green ; one or two small round blue spots above the axil ; hind 

 limbs with round light spots edged with blackish ; lower parts white or pale yellow, 



* Two superposed postnasals in one specimen ( $ , Morea). 



t 4 on both sides in 8 specimens, 4 on one side and 5 on the other in S, 5 on both sides in 1.
