 Old Castille, New Castille, Valencia, Murcia, Andalusia) and Portugal 

 (Estremadura, Al^'arve). The occurrence of this lizard in the South

The form i^-enerally distributed in North Algeria agrees iu all 

 essentinl characters with the typical form, excej)t that the subocular 

 appears to border the mouth constantly, and to a greater extent. The 

 scales on the back are likewise juxtaposed and convex and may be 

 either nearly smooth or rather strongly keeled, with every gradation 

 between the two extremes. 



Suture between the nasals very short, f rarely more that I the length 

 of the frontonasal, which is very rarely divided into two;j: ; an azygos 

 prefrontal very rarely preseut§ ; disintegration of the first supraocular 

 sometimes restricted to a division into two shields, or one shield and 

 one granulell ; the distance between the second loreal and the anterior 

 large supraocular often much less and never more than the length of 

 the latter ; suliocular entering the labial border Vtetween the fourth and 

 fifth upper labials ; tympanic shield nearly always present and some- 

 times rather large. Tail IJ, to 1| times as long as head and body.
