154 ME. G. A. BOULENGEE ON THE 



spots on the ventrals, and a few of the females have some scattered black dots on 

 the same region. The series of granules between the supraoculars and the supra- 

 ciliaries is complete in 18 specimens. 4 specimens have five anterior labials on each 

 side, 6 have five on one side and four on the other, and one has three on each side. 

 In two specimens the rostral forms a suture with the frontonasal. In all but two 

 the masseteric disk is large, and in one only is the parietal excluded from contact 

 with the upper postocular. Femoral pores 20 to 29. 



Out of four specimens from Cagliari, received from Count Peracca, one has five 

 anterior upper labials. Femoral pores 21 to 25. 



In nearly all these specimens the rostral shield touches or enters the nostril. In this 

 respect the var. quadrilineata tends towards the var. pityusensis, in w^hich the rostral 

 constantly enters the nostril. There are many points of agreement between these two 

 varieties, and it now appears to me not improbable that the Iviza lizard, which differs 

 considerably from the Wall-Lizards of the Spanish Peninsula, may be directly derived 

 from those inhabiting Corsica and Sardinia. This would be in accordance with what 

 we know of the herpetological fauna of the Balearic Islands, which lacks any truly 

 Spanish elements, and shows decided Eastern afiinities in the presence of Testudo 

 groeca and Burfo viridis, to say nothing of the reported occurrence on Minorca of 

 Lacerta muralis, var. tiliguerta, which, in view of the present knowledge of its 

 distribution, may, after all, not be due to human agency, as I was first inclined to 

 believe. 



Var. SAEDOA. 



Since the appearance of my first contribution, Count Peracca has published * 

 supplementary notes on his L. sardoa, based on the examination of 26 further 

 specimens. The lizard was then believed to be confined to a single valley on the 

 Gennargentu, but on a recent rapid inspection of the collection in the Florence 

 Museum, Count Peracca and I found three large specimens, labelled as from Monte 

 Limbara. In these specimens, the nasals are narrowly in contact with each other 

 behind the rostral, whilst in the 26 specimens described by Peracca the frontonasal is 

 in contact with the rostral, usually forming an extensive suture. The postnasal 

 is constantly single, and, with three exceptions, the parietal is in contact with the 

 upper postocular. There are more frequently 4 than 5 upper labials in front of 

 the sub ocular. 



According to the author's tabulation, the number of scales across the body varies 

 from 62 to 76, the transverse series of ventrals from 23 to 26, the collar-shields from 

 11 to 15, the gular scales, in a longitudinal series, from 29 to 38, the femoral pores 

 Irom 21 to 30, frequently with a second series of rudimentary pores, as noticed in the
