364 Lacertidse. 



slender compressed. Tail about twice as long as head and body, 

 depressed at the base, slightly compressed posteriorly. 



Upper head-shields smooth ; nasals in contact behind the rostral, 

 the suture between them ^ to f the length of the frontonasal, which 

 is broader than long ; prefrontals as long as broad, forming a median 

 suture ; frontal as long as its distance from the nasals or the end 

 of the snout, 1| to 2 times as long as broad, narrow behind, grooved 

 along the middle ; parietals a little broader than long; interparietal 

 smaller than the frontoparietals ; occipital minute or absent. Two 

 large supraoculars, preceded by a scaly or granular area, and followed 

 by a series of gramiles and a small band-like shield ; a series of 

 granules on the inner side of the supraoculars and one or two between 

 the latter and the supercillaries, which are 5 to 7 in number. Eostral 

 a little broader than deep, narrower beneath than above; lower nasal 

 touching the rostral or narrowly separated from it,* resting on the 

 2 or 3 anterior upper labials ; anterior loreal as long as deep or deeper 

 than long, shorter than the second ; subocular strongly Iceeled below 

 the eye, much narrowed beneath and bordering the mouth between the 

 5th and 6th or 6th and 7th, rarely 7th and 8th, upper labials. Temporal 

 scales finely granular and smooth above, much larger beneath ; tympanic 

 shield distinct ; 4 or 5 projecting granules in front of the ear. 



5 pairs of chin-shields, the 3 anterior in contact in the middle ; 

 21 to 27 gular scales on a line between the symphysis of the chin- 

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

 curved, with 9 to 12 plates. 



Scales granular, smooth, 54 to 62t across the middle of the body. 

 Ventral plates as long as broad or a little In'oader than long, forming 

 14 oblique longitudinal and 30 to 33 transverse series. Preanal 

 region covered with numerous small shields, of which the postero- 

 median is often enlarged. 



Upper surface of arm with rhombic smooth scales which are larger 

 than the largest gulars. Upper surface of tibia with granular scales 

 similar to the dorsals ; lower surface with one series of large and one 

 of small plates. 12 to 16 femoral pores on each side. Fingers and 

 toes compressed, with 3 series of scales ; fingers scarcely serrated 

 laterally ; toes with moderately sti'ong lateral fi-inge on the outer 



* According to Bedriaga, S. gnim-grzimaUoi diftVrs from <S'. Uncohda in 

 having the lower nasal in contact Avith the rostral ; but the specimen of 

 ;Si. linenlata, one of the types, received from Dr. Kikolsky presents the same 

 condition, which I find also in 2 out of 4 spt.'cimeus from 'rransoaucasia ; the 

 character is therefore not of specific importance, just as in Eremias velox.
