132 ME. G. A. BOULENGER ON THE EEPTILES 



both sides. Young longitudinally streaked black and white on the body, with round 

 white spots on the limbs ; tail pink ; adult greyish or brownish, with more or less 

 distinct traces of light and dark longitudinal lines and longitudinal series of black and 

 pale spots ; sometimes with large blue ocelli on the sides. 



This species might be divided into two forms — the typical form from Europe and 

 Algeria, with smooth or faintly keeled scales, and the var. lineomaculatus, D. & B., 

 from Morocco and Algeria, with strongly keeled scales, — were it not that there exists so 

 complete a transition between the two that it is almost impossible to draw the line. 

 It is a fact, however, that all specimens from Morocco, of which very many have been 

 examined, have strongly keeled scales, and, with rare exceptions, the subocular does not 

 reach the lip, but forms an angle inferiorly, wedged in between the fourth and fifth, 

 rarely fifth and sixth, labials. In Algerian specimens the dorsal scales may be perfectly 

 smooth, or more or less distinctly keeled, and it is but exceptionally that the subocular 

 does not border the lip. Out of 14 Spanish and Portuguese specimens preserved in the 

 British Museum, the subocular borders the lip in two specimens on both sides, and in a 

 third on one side only, the 11 other specimens being in this respect like those from 

 Morocco. 



The number of scales round the body (ventrals included) varies from 70 to 85, and 

 that of femoral pores on each side from 22 to 27. 



The largest Algerian specimen measures from snout to vent 70 millim., tail 110. 



A. vulgaris inhabits the south of France (where very few specimens have been found), 

 the Spanish Peninsula, Morocco, Algeria north of the Sahara, and, probably. Northern 

 Tunisia. It is very common at Tangier, and is on record from Casablanca, Mogador, 

 Morocco, and the Plateau of Chiodma. In Algeria it is found on the coast and rarely 

 on the Plateaux. M. Lataste obtained specimens from Oran, Daya, Plateau of Sersou, 

 Algiers, Wed Sedeur (between Laghouat and Djelfa), Setif, between Aumale and Beni 

 Mansour, Bordj-Bou-Arrerij, and Tebesa. 



4. Ebemias, Wiegmann, 1834. 



Nostril pierced between three (or four) nasals. Eyelids movable. Collar more or 

 less distinct. Dorsal scales small ; ventral shields tetragonal, feebly imbricate. Digits 

 with keeled lamellae inferiorly, not denticulated laterally. Femoral pores. 



A single species in Barbary. 



1. Ekemias gdttulata, Lichtenstein, 1823. 

 E. pardalis, Gervais, Guiclienot, Strauch. — Podarces simoni, Boettger. 



Snout rather pointed ; nasals more or less swollen. Lower eyelid with a more or 

 less transparent disk formed of one, two, or several scales. A small occipital, in contact 

 with the interparietal ; no aiiricular denticulation. Collar curved or more or less 

 angular, free or attached in the middle. Dorsal scales granular, smooth. Ventral 

 plates in straight longitudinal and transverse series, broader than long; 10 longitudinal
