Very near the var. brueggemanni, but approaching the var. hedriagse* 



Head rather strongly depressed. 



The rostral does not touch the nostril. The series of granules 

 between the supraoculars and the superciliaries is sometimes com- 

 plete (it is so in the larger of the two types), but the first supei'ciliary 

 usually forms a suture with the supraocular. Parietal in contact with 

 the upper postocular. Masseteric shield sometimes large, sometimes 

 small, or broken up. Two specimens ( 9 ) have 5 anterior labials on 

 both sides, the others have 4. 



Dorsal scales granular, feebly but distinctly keeled, 60 to 74 across 

 the body, 40 to 67 transverse series in the middle of the back corre- 

 sponding to the length of the head, 4 or 5 on the sides corresponding 

 to a ventral plate. Tibial scales a little smaller than dorsals, very 

 distinctly keeled. 19 to 26 femoral pores (exceptionally 18). 26 to 

 33 lamellae under the fourth toe. The hind limb reaches the collar, 

 or between the collar and the ear, in males, the axil in females. 



In coloration often very similar to var. hedriagx. Upper parts and 

 sides of body and limbs green or yellowish with a black network 



* " Le Lezard des Murailles provenant de File de Pianosa, laisse voir sur un 

 beau fond vert des baiides noires transversales et ondulees. Les parties 

 inferieures du corps sont bleuatres. Les series longitudinales de plaques 

 ventrales qui confinent aux flancs sont d'un beau bleu marin tacliete de noir. 

 Les formes de ce lezard offrent des caracteres nouveaux. Sa tete est deprimee. 

 le cou est fortement renfle et beaucoup plus large que la tete ; son tronc est tres 

 epais. Far ses formes, cette sous-variete parait etre tres voisine dxt Lezard oxycephale 

 de Fitzinger [read L. hedriagx, Camerano]." Bedriaga, Bull. Soc. Zool. France, 

 p. 205. I had quite independently arrived at the same conclusion on examining 

 a specimen from Pianosa, near Elba.
