66 Lacertidee. 



what more elongate and always less convex, 1| to 1| times as long as 

 broad,* its depth equal to the distance between the anterior corner of 

 the eye and the tympanum, its length 3f to 4i times in length to vent 

 in males, 4| to 6 times in females ; snout less obtuse, as long as the 

 postorbital part of the head or slightly less; cheeks more or less 

 swollen in the males ; pileus 2 to 2\ times as long as broad, in adult 

 males often very uneven or rough.f Neck usually a little constricted. 

 The hind limb reaches between the wrist of the adpressed fore limb 

 and the collar in males, the wrist or the elbow, rarely the axil, in 

 females ; the limb shorter, on an average, in specimens from Central 

 and South-eastern Europe than in those from Italy. Foot 1 to If 

 times the length of the head, rarely slightly less, in males, \\ to If 

 times in females ; digits feebly compressed. Tail cylindrical, gradually 

 tapering. If to 2f times the length of head and body, usually about 

 twice, If to 2^ times in the oriental specimens mentioned further on ; 

 shorter in the very young. 



Nostril pierced between 5 or 6, rarely 4, shields. Eostral touching 

 or entering the nostril,J not so deep as in L. agilis ; suture between 

 the nasals short or very short,§ rarely half the length of the 

 frontonasal, which is nearly always broader than the internarial 

 space,|| and usually broader than long; the sides of the frontonasal 

 nearly always in contact with the upper postnasal and with the 

 anterior loreal, or, if the latter be absent, with the second loreal, 

 sometimes*! with the three shields; prefrontals usually forming 

 an extensive suture, an azygos shield rarely present between them*''' ; 

 frontal as long as its distance from the nasals or the end of the 

 snout, li to 1-1- times as long as broad, broader than the supraoculars, 

 except in the young, often concave in old specimens, its outline usually 

 rounded in front, in males sometimes trilobate ; often a groove (suture 

 between the frontal bones) along the middle of the shield, giving it the 

 appearance of being divided into two ; parietals If to If times as long 



* Fatio is evidently mistaken in stating "la plus grande largeur egalant, en 

 general, la moitie de la longueur." 



+ Often much more than in males of similar size of the var. major. 



I Exceptions in a male from Jersey, in a female from Korito, and in a female 

 from Salonioa. 



§ The rostral is in contact with the frontonasal in a female from Turin. An 

 azygos shield separates the nasals in two females from St. Epain. 



II Exceptions in a female from Prague and in one from Znaim. 

 T In several specimens from Trance and the Channel Islands. 



** In a male from Cattaro and in a female from Znaim. In a female from 

 Valdehlore and in another from Korito, the frontonasal is in contact with the 

 frontal.
