Eremias. 305 



with sharp canthus and feebly grooved loreal region ; no frontal con- 

 cavity ; cheeks swollen. Pileus If to 2 times as long as broad. Neck 

 as broad as the head. Hind limb reaching the ear or the eye in males, 

 the collar or between the collar and the ear in females ; foot 1^ to 1\ 

 times as long as the head ; toes rather slender, feebly compressed. 

 Tail 1| to about 2 times as long as head and body. 



Upper head-shields flat or rather convex, smooth. Eostral in 

 contact with the frontonasal, with rare exceptions ; frontonasal as 

 long as broad or a little longer than broad; prefrontals as long as 

 broad or a little longer than broad, forming a very short median 

 suture, or separated by one or two small azygos shields* ; frontal as 

 long as or shorter than its distance from the end of the snout, l^- to 

 If times as long as broad, narrow behind, in contact along half the 

 length of its lateral border with the large supraoculars or separated 

 from them by a series of granulest ; parietals as long as broad or a 

 little longer than broad ; interparietal as large as or larger than the 

 frontoparietals ; occipital as broad as or narrower than the interparietal 

 and i to i its length, rarelyj separated from it by a small shield. 

 Two supraoculars, the first as long as or shorter than its distance 

 from the second loreal, the space in front of it filled by 13 to 30 small 

 scales or granules ; 8 to 12 superciliaries, first not or but little longer 

 than the following, separated from the supraoculars by 1 or 2 series 

 of gi'anules, sometimes 8 series behind. Three nasals, lower in contact 

 with the rostral and the first upper labial, posterior small ; anterior 

 loreal as long as deep or a little longer than deep, shorter than the 

 second ; 5 to 7, rarely 4, upper labials anterior to the subocular, which 

 is keeled below the eye and largely borders the mouth, its lower border 

 much shorter than the upper. Temporal scales granular, smooth ; 

 no tympanic shield ; no auricular denticulation. Lower eyelid 

 opaque or semitransparent, with 10 to 14 enlarged scales, in two rows, 

 in the middle. 



5 pairs of chin-shields, the first three in contact in the middle. 24 

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

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

 straight, free, composed of 7 to 13 plates. 



Scales juxtaposed, granular, smooth, round or squarish and flat on 



* In 6 specimens out of the 12 examined. 



+ In 6 specimens. Also in the type described by Smith in 1838, which I 

 believe to recognize in one of the specimens (6) of E. burchelli in Gray's Cata- 

 logue, which does not agree in the position of the subocular shield with the 

 diagnosis in that work. 



J In one specimen only.
