124 ME. G. A. BOULENGER OK THE REPTILES 



The following notes are taken from the specimens in the British Museum : — 



The occipital is constantly broader than the interparietal, and usually narrower than 

 the frontal ; however, in a male specimen from Tunis it is quite as broad as the 

 frontal, not larger than in a specimen of the typical form from Ferrol (Spain)\ The 

 dorsal scales are small, oval-subrhomboidal, feebly keeled, and their number across the 

 middle of the body varies from 70 to 80. The ventral shields form 8 longitudinal 

 series, of which the two median and the outermost are the narrowest. Femoral pores 

 vary from 14 to 16 on each side, 14 being the usual number. Two or three semicircles 

 of small shields on the anal region. 



The coloration varies greatly, green being the ground-colour. The young are usually 

 ornamented all over with large bluish-white black-edged ocelli, like the young of the 

 typical L. ocellata ; others are uniform gi'een. The adult may be uniform or speckled 

 with black, like typical L. vlridis ; or with black rings or small black and white ocelli, 

 thus very similar to the Iberian L. viridis, var. schreiheri ; or with large blue ocelli on 

 the sides like the typical L. ocellata. Lower parts uniform greenish yellow. 



The largest specimen measures 165 millim. from snout to vent. 



This fine Lizard is found all over Algeria, as far south as the northern border of the 

 Sahara. M. Lataste found it very common at Algiers, Aumale, Setif, Bona, Batna, 

 Lambesa, El Guerrah, Bougia ; and he received it from the Plateau of Sersou. 

 Dr. Strauch records it from Oran and Constantine ; J. von Fischer from Boghar, 

 Blidah, La Chiffa, Tiaret, El Kantarah, El Rouached, St. Arnaud ; and Dr. Kobelt 

 collected specimens at Tlemsen and Biskra. In Tunisia, it is known from the city of 

 Tunis, and M. Lataste observed it in the northern parts, between Ferriana and Tebesa. 

 Marquis Doria found it on Galita Island.

Var. TANGiTANA, Boulenger, 1887. 



This interesting form was recently discovered at Tangier by M. H. Vaucher, from 

 whom I received 11 specimens. There was no previous record of either L. ocellata or 

 L. viridis in Morocco. The var. tangitana comes very near the Algerian var. pater, but 

 diverges from it as well as from L. ocellata typica in the still smaller dorsal scales, of 

 which there are 77 to 100 across the middle of the body, and the greater number of 

 femoral pores, viz. 17 to 21. In the usually smaller size of the occipital and the 

 number (6 or 8) of longitudinal rows of ventral shields, it approaches nearer still the 

 Spanish-Portuguese form of L. viridis (var. schreiheri, Bedriaga), from which some 

 specimens are with respect to these two characters undistinguishable. 



In some specimens the occipital is not or but slightly broader than the interparietal ; 

 in others its greatest width equals that of the frontal. 24 to 28 scales on a line 

 between the chin and the collar; latter with II to 13 shields. There are usually eight
