Habitat. — The range of this form is confined to the hilly or 

 mountainous districts of the Spanish Peninsula, up to an altitude 

 of 1000 metres. It is known with certainty from the Asturias, 

 Galicia, Leon, New Castille, and Portugal. The localities given by 

 Bosch for L. viridis in Seville, Vascongadas, and Old Castille, 

 probably apply to it. 



The following synopsis will help in the identification of the 5 forms : — 



Forma typica. 40 to 55 scales across middle of l)ody, usually 42 to 

 50 ; ventral plates in 6 longitudinal series, very rarely 8 ; occipital 

 very rarely broader than interparietal ; granules betAveen the supra- 

 oculars and the superciliaries often absent or much reduced; tympanic 

 shield often absent ; young without light vertebral streak. 



Var. strigata, Eichw. 38 to 49 scales across middle of body ; 

 ventral plates in 6 or 8 longitudinal series ; occipital very rarely 

 broader than the interparietal ; usually a series of granules between 

 the supraoculars and the superciliaries ; tympanic shield present ; 

 young with a light vertebral streak.
