6. DEremias l^rennevi, Petees, 



A single specimen. Route from Obbia to Berbera. 



Head much depressed ; snout long , narrow , and acutely 

 pointed. Nasals slightly swollen, lower divided, the nostril pierced 

 between four shields; upper head-shields strongly striated; fron- 

 tonasal longer than broad , separated from the rostral ; two 

 praefrontals; frontal strongly grooved ; three large supraoculars, 

 anterior smallest and not bordered with granules, the two others 

 bordered with granules except anteriori}' ; interparietal small , 

 separated from the very small occipital by another small shield; 

 an elongate shield on the outer border of the parietals ; tem- 

 poral scales granular, obtusely keeled; no auricular denticulation; 

 lower eyelid scaly ; subocular not reaching the lip, wedged in 

 between the sixth and seventh upper labials; the two first 

 labials in contact with the nasals; the two anterior pairs of 

 chin-shields in contact. Collar carved, perfectly free, with seven 

 plates. Dorsal scales rhomboidal, juxtaposed or subimbricate , 

 keeled, 68 across the middle of the body. Six straight longitu- 

 dinal series of large, broad ventral plates ; 25 straight transverse 

 series. A large median prseanal. The hind limb reaches the 

 nostril; toes strongly compressed; 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 ; upper surface of arm with 

 enlarged pluricarinate scales; upper crural scales much larger 

 than dorsals, imbricate, and strongly keeled. 21 or 22 femoral 

 pores on each side. Tail about twice and a half as long as head 

 and body ; upper caudal scales strongly keeled, basal subcaudals 

 smooth. The adult specimens, recently described by Mocquard 

 (Mém. Cent. Soc. Philom. 1888, p. 115, pi. XI. %. 1) are 

 stated to be uniform rufous grey. The young specimen from 

 which the above characters are taken, and which agrees with 

 Peters's description, resembles strikingly the young oi Accmtho- 

 dactylus hoskianus: six reddish white lines along the body, se- 

 parated by broader black intervals along each of which runs
