II.— SPANISH PENINSULA. 



(Plates XXIV. & XXV.) 



The typical form, in no respect distinguishable from that inhabiting Central Europe, 

 certainly occurs in the northern parts. The British Museum contains specimens from 

 Corunna (Seoane) and from Barcelona (Thomas and Pocock). Specimens from Arnao 

 (Bedriaga) are in the Lataste Collection 1 . 



The belly of the adult males is spotted with black, and the masseteric plate is well 

 developed, except in one specimen from Barcelona, in which it is altogether absent. 



Larger, more handsomely marked specimens occur on the islet La Deva, opposite 

 Arnao, and have been described by Bedriaga as 



Var. rasquinetii, Arch. f. Naturg. 1878, p. 260, pi. x. figs. 1 & 2. 



Dark olive-green to dark brown above ; sides of body sky-blue with a black network ; 

 a series of black spots forms an interrupted stripe along the middle of the back ; large 

 black spots on the upper surface of the tail ; lower parts bright red, much spotted with 

 black ; the whole of the outer row of ventral shields and the outer half of the adjacent 

 ventral shields sky-blue. 



The type specimen, male, of which the life-coloration has been described and figured 

 by Bedriaga, is now preserved in the British Museum.
