7. Eremias ery tlxrosticta , sp, n. (PI. I, fig. 2). 



Numerous specimens. Route from Obbia to Berbera. 



Head much depressed-; snout long, narrow, and acutely pointed. 

 Nasals more or less swollen, sometimes quite as much as in 

 E. guttulata, the nostril pierced between four shields; upper 

 head-shields perfectly smooth; frontonasal longer than broad, 

 separated from the rostral ; two praefrontals ; frontal strongly 

 grooved ; three large supraoculars, anterior smallest and in con- 

 tact with the prsefrontal, loreal, and anterior supraciliary, but 

 usually separated from the second supraocular by a series of 

 granules ; a series of granules surrounds the second and third 

 supraoculars, which are in contact with each other ; interparietal 

 and occipital small, separated from each other by one, two, or 

 three small shields; an elongate shield or series of shields on 

 the outer border of the parietals; temporal scales granular, ob- 

 tusely keeled; no auricular denticulation ; lower eyelid scaly; 

 subocular not reaching the lip, above the sixth and seventh or 

 seventh and eighth labials ; the two or three first labials in 

 contact with the nasals ; the two or three anterior pairs of chin- 

 shields in contact. Collar curved, perfectly free, with six to nine 

 plates. Dorsal scales granular, round or hexagonal, juxtaposed, 

 keeled, 53 to 60 across the middle of the body. Eight straight 

 longitudinal series of ventral plates, the six principal broader 

 than long, the outer narrower but nevertheless very well de- 

 veloped; 24 to 27 straight transverse series. Prseanal region 

 usually covered with several irregular shields disposed in pairs; 

 an enlarged median prseanal shield, as in E. brenneri and E. mu- 

 cronata, is very seldom present. The hind limb reaches the eye, 

 or halfway between the latter and the nostril ; foot as long as 

 the distance between the arm and the end of the snout; one 

 series of large and one of small subtibial plates ; a series of 

 large smooth shields on the upper surface of the arm ; upper 

 crural scales much larger than dorsals, imbricate, feebly keeled, 

 15 to 20 femoral pores on each side (usually 17 to 19). Tail
