362 Lacertids?. 



5 or 6 pairs of cliin-sluelds, the 3 first meeting in the niiddle * ; 

 36 to 51 gular scales in a straight line between the symphysis of the 

 chin-shields and the median collar-plate; no gular fold. Collar 

 sti'aight, with 12 to 10 small plates. 



Scales granular and smooth, increasing in size on the lower part of 

 the side and passing gradually into the ventrals, 90 to 110 across the 

 middle of the body. Ventral plates as long as broad or longer than 

 broad, te.ssellated or forming oblique longitudinal series, in 40 to 46 

 transverse series, the longest of which contains 24 to 28 plates. f 

 Preaual region covered Avitli small irregular plates. 



Upper surface of fore limb with rather large, rhombic, Iceeled scales. 

 Upper surface of tibia with rhombic keeled scales anteriorly, graduating 

 into small smooth granules further back ; lower sui-face with one row 

 of transversely enlarged plates and 3 rows of smaller plates. 19 to 

 23 femoral pores X on each side, the two series narrowly separated in 

 the middle. Fingers with 4 series of scales, svmmetricallv and rather 

 sti'ongly serrated on both sides, feebly unicarinate beneath ; toes with 

 3 series of scales, the outer forming a rather strong fringe, the sub- 

 digital lamellae strongly keeled § and 22 to 24 in number untler the 

 fourth toe. 



Upper caudal scales rhombic, rather strongly and diagonally keeled, 

 lower, on the base of the tail, smooth or very obtusely keeled ; a band 

 of granules, continued from the back, along the middle of the base of 

 the tail ; 40 to 50 scales in the fourth or fifth whorl behind the post- 

 anal granules. 



Grreyish or sand-colour above, with a darker network enclosing 

 round light spots ; sometimes a rather indistinct dark vertebral 

 streak ; tail with 3 blackish longitudinal streaks in the basal third. 

 A female specimen in the Paris Museum is dotted with blackish 

 above ; a broad dark lateral band, spotted with whitish and edged 

 above and beneath by a narrow whitisli streak. The young is 

 described by Werner as closely dotted with dark and light above; 

 upper lip and lower surface of tail orange-red. Lower parts white. 



* 2 on one side and 3 on the other in one specimen. 



t 20 to 28 according to Werner. 



X 16 to 2-i according to Werner. 



§ In describing t!ie subdigital lamella? of the toes as smooth, Stranch lias 

 evidently made a mistake in their orientation, taking tlic median keel and the 

 serration formed liy it to repres(>nt the enter border of llie toe. I am inclined 

 to think that the flattened toes of S. grammica are due to a rotation of tlie axis 

 of the digit, owing to which the o^ter ha.lf has come to represent the whole 

 lower surface.
