130 Lacertidse. 



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

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

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

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

 calated betAveen the interparietal and the occipital.f Normally four 

 supraoculars, J first small, § 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 separatiiig the nostril 

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

 part of the anterior loreal ; a single postnasal,^ 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 Bourboule. 

 In a male from La Ferte-Mace, 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 forming- 

 a triangle. 



t This anomaly, althovigh less frequent than in L. fraticola, is found in a 

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

 Aube, Brvissels, Bx'osteni, Dambovita, Moscow, Sachalien) aboiit in the same 

 proportion as in L. tnuralis. 



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

 del Fain, near Pontresina. 



§ Earely rather large and extensively in contact with the frontal (female 

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



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

 not very exceptional. 



*![ 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 Koumanian specimens 

 there are 3 in 18 cases 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.
