206 Lacerti(hc. 



also divided into 2 or 3 and often separated from the frontoparietals ; 

 the two principal supraoculars not or but slightly broader than the 

 posterior part of the frontal ; 3 supei'ciliaries, rarel_v 4, second very 

 long ; a complete series of granules between the supraoculars and the 

 superciliaries, exceptionally two. A single nasal, in contact with the 

 first upper labial, followed by 2 superposed postnasals ; anterior loreal 

 shorter than the second ; 4 upper labials* anterior to the subocidar, 

 which is much narrower beneath than above and borders the mouth. 

 2 large, keeled upper temporals, anterior the longer and usually in 

 contact with the fourth supraocular ; temporal scales moderately large, 

 hexagonal, keeled ; a rather large tympanic shield. 



5 or 6 pairs of chin-shields, the two or three autei'ior in contact in 

 the middle ; gular scales large, flat, iniliricate, 15 to 20 in a straight 

 line between the symphysis of the chin-shields and the ventral plates ; 

 no gular fold ; collar indistinct in the middle, free and with 2 or 3 large 

 plates on the side. 



Scales large, rhombic and imbricate from the nape, generally in- 

 creasing in size to the tail, with strong keels, straight or slightly 

 oblique, a few on the nape sometimes bicarinate ; lateral scales as 

 large as or a little smaller than the dorsals, j)assing gradually into the 

 ventral plates, which are in 6 or 8 longitudinal and 24 to 29 transverse 

 series (24 to 27 in males, 29 in females) ; 26 to 32 scales and plates 

 round the middle of the bodv. A large preaual plate, bordered by one 

 or two semicircles of smaller plates, or two large preanal plates, one in 

 front of the other. 



Scales on upper surface of tibia rhombic and keeled, as large as or 

 a little smaller than the dorsals. 8 to 13 femoral pores on e;ich side, 

 usually 9 to 11. Subdigital lamelte bi- or tricarinate, 16 to 19 under 

 the fourth toe. 



Caudal scales strongly keeled, upper lai-ger than lower, 16 to 20 in 

 the fourth or fifth whorl behind the postanal granules. 



Brown above, with two yellowish white streaks on each side, the 

 upper, which is exceptionally absent,t from the superciliary edge to 

 the tail, the lower, better defined and often black-edged, from the 

 upper lip, through the tympanum, to the base of the hind limb; the 

 space between the two light streaks darker than the back, or closelv 

 spotted with black ; sides of belly sometimes black, with blue spots ; 

 tail move or less reddish ; lower parts white. 



* 5 on one side in a female from the Brumaglieriies. 



t Contrary to the tendency in the other species of the genus, which is for 

 the lower lateral streak to disappear before the upper.
