frontonasal broader than long, broader than the internarial space, in 

 contact with the upper postnasal and the anterior loreal ; frontal as 

 long as its distance from the end of the snout, 1 j;- to 2 times as long as- 

 broad, usually narrower behind than the major supraoculars; parietal 

 1\ to li times as long as broad, outer border convex, and in contact 

 with the upper postocular ; occipital ^ to f the length of the inter- 

 parietal, as broad as or broader than the latter, rarely a little narrower ; 

 second supraocular longer than third ; 5 or 6, rarely 4, superciliaries, 

 first or second longest, the suture between these two usually oblique, 

 rarely vertical ; a series of granules between the major supraoculars 

 and the superciliaries, the series complete or incomplete through the 

 first or first and second superciliaries forming a suture with the supra- 

 ocular or, rarely, reduced to 2 or 3 granules. Rostral not touching 

 the nostril ; first upper labial not always entering the nostril, and if so 

 only at a small point ; two superposed postnasals ; two loreals, first as 

 long as or shorter than second. 4 upper labials anterior to the sub- 

 ocular,'' the lower border of which is much shorter than the upper,, 

 sometimes f very short owing to a part of the shield having become 

 detached as an accessory fifth anterior upper labial. Temporal region 

 with moderately large shields or small scales ; masseteric shield present,, 

 small or large, sometimes divided into two+ ; tympanic present, large ; 

 a rather large upper temporal, forming a suture with the fourth 

 supraocular, followed by 2 to 4 scales. 



Lower eyelid in the middle with one or two series of 6 to 8 enlarged 

 scales, which have a tendency to become semitransparent. 



Pterygoid teeth present. 



17 to 20 scales and granules in a straight line between the symphysis 

 of the chin-shields and the median collar-plate ; gular fold distinct ; 

 collar strongly serrated, composed of 7 to 10 plates. § 



Body covered with moderately large, juxtaposed or subimbricate, 

 hexagonal or rhombic scales, which ai'e strongly and diagonally keeled 

 on the back, larger and losing the keels towards the ventrals ; 33 to 

 43 scales across the middle of the body, 2 transverse series (rarely 3 

 here and there) corresponding to a ventral plate, 19 to 30 in the 

 middle of the back corresponding to the length of the head. Ventral 

 plates overlapping, more or less distinctly detached from each other 



* 3 on one side in a female from Angora. 



t In one male from Berchetti Mandam, this reduction of the lower part of the 

 subocular being the nearest approach, in the genus Lacerta, to a condition 

 frequent in Acanthodactylus and Eremiax. 



X Rarely indistinct, according to Werner. 



§ Up to 12 according to Werner.
