Habitat. — Sandy and rocky arid tracts in Spain (Provinces Leon, 

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

 (Estremadura, Algarve). The occurrence of this lizard in the South 

 of France is doubtful. A few specimens are stated to liave been found 

 in the de})artnients Hcrault and Gard in the first, half of the last 

 century, but the lizard has not been rediscovered since, any more than 

 in the neighbouring part of Italy, notwithstanding Bonaparte's state- 

 ment.* 



Var. BELLI, G-ray (vars. vulgaris, Jcsourensis, Doum.). 



The form generally distributed in North Algeria agrees in all 

 essential characters with the typical form, except 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 nearlv smooth or rather stronglv keeled, with everv gradation 

 between the two extremes. 



Suture Itetweeu the nasals very short, t rarely more that I the length 

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

 prefrontal very rarely present§ ; disintegration of the first supraocular 

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

 one granule|| ; the distance between the second loreal and the anterior 

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

 the latter ; subocular entering the labial border between the fourth and 

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

 times rather large. Tail 1^ to !'§ times as long as head and body. 



58 to 70 scales across the middle of the body. 20 to 30 femoral 

 pores on each side. 18 to 23 lamellae under the fourth toe.
