Owing to the variability of this species, the following detailed 

 description is based exclusively on Egyptian specimens, which 

 represent in the narrowest sense the Lacerta pardalis of Lichtenstein, 

 the types of which I have examined in the Berlin Museum. 



Habit stout, body depressed. Head 1^ to l^ times as long as broad, 

 its length 4 to 4f times in length to vent, its depth equal to the 

 distance between the anterior corner or the centre of the eye and 

 the tympanum ; a more or less distinct lanceolate concavity from the 

 frontonasal to the middle of the frontal ; snout obtusely pointed, as 

 long as the postocular part of the head, with rather sharp canthus and 

 feebly concave loreal region ; nasals feebly swollen. Pileus If to 2 

 times as long as broad. Neck as broad as the head or broader. The 

 hind limb reaches the shoulder, the collar, or, rarely, a little beyond 

 the collar in males, the elbow, the axil, the shoulder, or, rarely, the 

 collar in females ; foot 1 to 1^ times as long as the head ; fourth toe. 

 from the base of the fifth, as long as the head or a little shorter. Tail 

 1} to If times as long as head and body. 



Upper head-shields convex, rarely slightly rugose in the adult. 

 Suture between the nasals ^ to i the length of the frontonasal, which 

 is broader than long and a little broader than the internarial space ; 

 prefrontals usually a little longer than broad and forming a median 

 suture ; frontal as long as or shorter than its distance from the end of 

 the snout, 1^ to 2 times as long as broad, rounded or truncate in 

 front, narrow behind ; parietals as long as broad, or, usually, broader
