130 Lacertidss. 



with 2 to 4 temporals ; occipital very variable, always shorter than the 

 interparietal, though sometimes but slightly, as broad or a little 

 broader, exceptionally minute,* its posterior border often convex and 

 projecting beyond the parietals ; a small shield is sometimes inter- 

 calated between the interparietal and the occipital.t Normally four 

 supraoculars,! first smail,§ sometimes divided into two or even, very 

 rarely, three, or minute, reduced to a granule, rarely absent, second 

 and third large, equal or second the longer, fourth small but larger 

 than first, sometimes fused with the upper postocular, often not 

 in contact with the frontoparietal ; sometimes a fifth small supra- 

 ocular ; 4 to 6 (rarely 3) superciliaries, usually all in contact with the 

 supraoculars, sometimes with 1, 2, or 3, or even 4|| granular scales 

 between them ; suture between the first and second superciliaries 

 usually vertical. 



The nasal sometimes forms a narrow rim separating the nostril 

 from the first upper labial and is frequently in contact with the upper 

 part of the anterior loreal; a single postnasal,T[ often small ; anterior 

 loreal sometimes divided into two superposed shields, or absent**; the 

 postnasal and the two anterior loreals sometimes form together a 

 triangle, as in L. agilis ; 3 or 4, very rarely 5, upper labials anterior to 

 the subocular,tt which is often nearly as long above as beneath, but 

 varies considerably in form. Temporal shields very variable in shape 



* Males from Unterberg and Boussers, females from Poole and La Bourbonle. 

 In a male from La Ferte-Maoe, in another from Nikolavsk, and in a third from 

 Sachalien, there are 3 occipitals in a transverse line ; in a female from St. 

 Peter, Carniola, there are 5 ; in a female from Norway, 3 occipitals f orming^ 

 a triangle. 



+ This anomaly, although less frequent than in L. praticola, is found in a, 

 good many specimens (Denmark, Bloxworth, Falmouth, Clare Id., Kambouillet,. 

 Aube, Brussels, Brosteni, Dambovita, Moscow, Sachalien) about in the same 

 proportion as in L. muralis. 



t 5 on one side in a male from Brighton, on both sides in a female from Val 

 del Fain, near Pontresina. 



§ Barely rather large and extensively in contact ivith the frontal (female 

 from Cappagh), as figured by Leydig, op. cit. 



II Males from Thetford and Fowey, female from Rhyl. 2 or 3 granules is 

 not very exceptional. 



Tf 2 superposed postnasals on the right side in a, female from Heyst and on 

 the left side in another from Sachalien (Anderson). 



** In about 50 per cent, of the British specimens. 



ft 4 is on the whole more frequent than 3, but in British specimens both 

 numbers are about of equal frequency, and in a, series of Roumanian specimens 

 there are 3 in 18 oases out of 26. 5 anterior labials on the right side in males- 

 from Bloxworth, Unterberg, and Moscow, on the left side in a female from 

 Heyst.
