166 Lacertidse. 



often granular ; upper temporals, 1, 2, or 3, or more numerous and 

 not much enlarged ; masseteric and tympanic nearly always present,* 

 the former usually large, round or oval. 



19 to 32 scales and granules in a straight line between the 

 symphysis of the chin-shields and the median collar-plate, usually 21 

 to 27 ; gular fold usually distinct, indicated by one, two, or three 

 series of minute granules. Collar without, or with merely a trace of, 

 serration, composed of 7 to 13 plates, usually 8 to 11. 



Scales on body granular, juxtaposed, round or oval-hexagonal, more 

 or less distinctly keeled, rarely smooth,t often a little larger on the 

 back than on the sides ; 42 to 62 scales across the middle of the 

 bodyj ; 3 or 4, rarely 2 or 3 or 4 or 5, transverse series correspond to 

 one ventral j)late, 29 to 45 to the length of the head. Ventral plates 

 in 6 longitudinal§ and 23 to 32 transverse series, 23 to 28 in males, 

 25 to 32 in females ; the plates of the two median series as broad as 

 or narrower, usually much narrower, than those next to them, the 

 outer abruptly differentiated from the lateral scales. Preanal plate 

 very variable in size and shape, but usually large, bordered by one 

 semicircle of small plates, often with an outer semicircle of smaller 

 plates or scales, the median pair of the inner semicircle sometimes 

 enlarged, very rarely fused to one large plate. || 



Scales on upper surface of tibia granular, more or less distinctly 

 keeled, usually smaller than those on the back, rarely nearly as large. 

 13 to 27 femoral pores on each side.^ 20 to 29 lamellar scales under 

 the fourth toe, usually 21 to 26.** 



Caudal scales usually narrow, truncate or very obtusely pointed, 



* Totally absent in 7 out of 100 si^ecimens from Burgos, Spain, also in a 

 male from Hernani and in a few specimens from the Pyrenees. In a male from 

 Barcelona there are neither enlarged upper temporals nor masseteric shield, in 

 this respect agreeing with L. dugesii, which, however, has constantly two post- 

 nasals and five anterior upper labials. 



t In two specimens from Dinant, Belgium, in one from Bagneres de Bigorre, 

 and in most from Burgos and Barcelona. 



X 42-53 in Lower Austria, 45-57 in the Balkan Peninsula, 46-G2 in Spain, 

 47-62 in Prance and Belgium, 49-60 in Italy. 



§ In a female from Jersey some of the outer ventrals are divided into two, 

 thus forming 8 incomplete series. 



li Female from St. Lxmaire. 



If 13-19 in Lower Austria, 13-22 in the Balkan Peninsula, 13-21 in Spain^ 

 15-25 in Italy, 16-27 in Prance and Belgium. In a male from Pietrocamala- 

 Casale, Abruzzi, there is a second series of smaller pores, as is f re(|ueutly found 

 in the var. sardoa—G on the right side, 4 on the left. 



** As for the gular scales, and, curiously, in both cases 23 is the most frequent 

 numbei'.
