Lacerta. 119 



frontals fonniiio; an extensive suture*; frontal as long as its 

 distance from tlie nasals or the rostral, 1.} to 1| times as long as 

 broad, f broader than the supraoculars, sometimes with a median 

 groove; parietals 1} to 1| times as long as broad, in contact with the 

 upper postocular ; occipital usually as long as or longer than the 

 interparietal, and often much broader, sometimes as broad as the 

 frontal. Four supraoculars, first and fourth small, second often a 

 little longer than third ; 5 to 7 superciliaries, suture between first and 

 second oblique ; a series of granules, complete or incomplete, 7 to 12 

 in number, between the supraoculars and the superciliaries. Eostral 

 usually not entering the nostril, j a single postnasal, a little smaller 

 than the anterior loreal, which is about half or 4 as long as the 

 second; 5 upper labials § anterior to the subocular, which is much 

 narrower beneath than above ; 4 to 7 small upper temporals, the last 

 usually the largest ; the remainder of the temple covered with granular 

 scales with a more or less enlarged masseteric shield || and a narrow 

 tympanic. 



Pterygoid teeth present. 



Gular scales flat, juxtaposed or feebly imbricate, 32 to 50 between 

 the symphysis of the chin-shields and the median collar-plate, one or 

 two series of granules sometimes separating the third pair of chin- 

 shields ; gular fold more or less distinct. Collar entire or veiy slightly 

 serrated, composed of 9 to 14 plates. 



Dorsal scales roundish-rhomboidal, keeled, separated by minute 

 granules, the keels diagonal ; 78 to 101 scales across the middle of the 

 body* ; 42 to 55 transverse series, in the middle of the back, corre- 

 spond to the length of the head, 3 or 4 on the side correspond to one 

 ventral plate. Ventral plates in 12 or 14 longitudinal*'' series, usually 

 only those of the second and third series from the median line broader 

 than long ; 29 to 31 transverse series. Preaual plate small or very 

 small, bordered by 2, 3, or 4 semicircles of small plates, and by small 

 granules behind. 



Scales on upper surface of tibia smaller than dorsals, keeled, some- 

 times tricarinate. 23 to 31 femoral pores on each side. 29 to 37 

 lamellar scales under the fourth toe. 



* Separated by an azygos shield in 3 females. 



t Sometimes not longer than broad, according to C. Boettger and L. Miillei. 

 t Exception in a female in the Paris Museum. 

 § () on one side in two females. 



I Rarely absent according to C. Boettger and L. Miiller. 

 ^ 87 to 106 according to C. Boettger and L. Miiller. 



** The smaller outer plates, which are separated from their fellows in the 

 longitudinal series bv scales, are not reckoned.
