also, the granules sometimes reduced to 3 or 4 * ; in a few specimens 

 the series of granules beginning from the first supraocular t ; parietals 

 IJ to \\ times as long as broad, usually in contact with the upper 

 postocular, but sometimes not J ; occipital very variable, usually shorter 

 but often broader than the interparietal. Nearly constantly 4 upper 

 labials anterior to the subocular, § which is narrower beneath than 

 above ; temporal scales usually larger than in an average typical L. 

 muralis, with the tympanic shield always distinct and the masseteric 

 frequently so ; enlarged upper temporals narrow or absent. 21 to 32 

 iscales and granules between the symphysis of the chin-shields and the 

 median collar-plate ; gular fold very distinct ; collar more or less 

 'distinctly serrated, sometimes as much as in L. agilis, composed of 9 

 to 11, rarely 7 or 8, plates. 



Scales on the back roundish -hexagonal or oval-hexagonal, very 

 distinctly, often sharply keeled, the vertebral line usually with a more 

 or less regular band of much smaller granular scales ; lower lateral 

 scales as large as or a little smaller or a little larger than the dorso- 

 laterals, smooth or faintly keeled ; 50 to 67 scales across the middle of 

 the body, usually 53 to 62 ; 3 or 4 transverse series of scales corre- 

 ispond to one ventral plate, 33 to 50 to the length of the head. Ventral 

 plates in 6 longitudinal || and 23 to 31 transverse series (23-29 in 

 males, 27-31 in females). Preanal plate frequently rather small, with 



2 or 3 semicircles of small plates, but sometimes large and with a 

 single semicircle. Scales on upper surface of tibia smaller than 

 dorsals, more or less strongly keeled ; 23 to 30 lamellar scales under 

 the fourth toe, usually 25 to 29 ; 15 to 24 femoral pores on each side, 

 usually 17 to 22. 



Upper caudal scales strongly keeled and usually obtusely but distinctly 

 pointed behind, those on the sides oblique and diagonally keeled ; 30 to 

 40 scales in the fourth whorl behind the postanal granules. 



Typical examples of the var. campestris, as represented by speci- 

 mens from Venetia, the Po Valley, and Istria, have the upper surface 

 of the head, a vertebral band, the sides of the body and limbs, and the
