in contact with the frontoparietal" ; 4, rarely 3 or 5, superciliaries, 

 first longest, all in contact with the supraoculars, or with 2 or 3 

 granules between them. Nasal forming a suture with the anterior 

 loreal t above the small postnasal ; posterior loreal longer than the 

 anterior ; 4 upper labials X anterior to the subocular, which is narrower 

 beneath than above, sometimes very slightly. Temporal scales rather 

 small, smooth or very feelily keeled : tympanic shield present ; one 

 or two enlarged upper temporals often present. 



Mental much broader than long ; 4, rarely 5,§ pairs of chin-shields, 

 the two or three anterior meeting in the middle ; 19 to 24 gular scales 

 between the symphysis of the chin-shields and the median collar-plate, 

 anterior granular and smooth, posterior enlarged, imliricate, smooth or 

 faintly keeled and merging gradually into the collar, which is composed 

 of 8 to 11 rounded or obtusely pointed plates, the median smooth, the 

 outer feebly keeled. No gular fold. 



Dorsal plates obtusely pointed or rounded behind, in 6 longitudinal 

 series, with 1 or 2 series of smaller plates on the median line, or in 

 8 series in front and 6 behind ; sides with one upper and 3 or 4 lower 

 series of keeled scales and an intermediate granular area. Ventral 

 plates in 8 longitudinal and 22 to 28 transverse series, the outer pointed 

 and feebly keeled, the others smooth, broader than long and shaped as in 

 Lacerta vivipara. 30 to 40 plates and scales round the middle of the 

 body. Preanal plate large, smooth, entire (males), or longitudinally 

 divided or semidivided (females), bordered by one semicircle of small 

 plates. 



Upper surface of liml)s with rhombic keeled scales, much smaller 

 than dorsals. 3 femoral pores on each side.|| Subdigital lamellse 

 single or partly single and partly divided, 19 to 23 under the fourth 

 toe. 



Caudal scales strongly keeled, pointed or shortly mucronate, in 

 somewhat longer and shorter whorls alternately, the fourth or fifth 

 of which contains 16 to 20 scales. The scaliug of the regenerated tail 

 similar to that of Lacerta vivipara. 



Brown or olive-grey above, uniform or with irregular dark brown 

 spots, sides with a broad dark brown or black band, the upper border
