This variety was founded by Mr. Boulenger for the reception of 

 some lizards from Tangier, very nearly allied to the previous variety, 

 but differing from it and from L. ocellata typica in their much 

 smaller dorsal scales, numbering from 77 to 100 across the middle 

 of the body, and in their more numerous (17-21) femoral pores. Oa 

 the other hand, in their smaller occipital and in the number (6-8) of 

 the longitudinal rows of ventral scales, they manifest, as pointed out 

 by Mr. Boulenger, marked affinities to the Spanish-Portuguese form 

 of L. viridis, the var. schreiberi, Bedriaga, and so closely do they re- 

 semble it in these two respects that they are undistinguishable from 

 it. Until the discovery of these specimens from Tangier, L. ocellata 

 and L. viridis were unknown from Morocco. It is interesting 

 therefore to find the Morocco variety occurring at Tlemgen, but not 

 surprising, considering the proximity of this locality to Morocco. 

 This specimen, however, presents one variation by which it can be 

 distinguished from all the examples of var. tangitana in the 

 British Museum, and that is, that the shields along the collar are 

 much more numerous, being 22, whereas in w&xs. pater and tangitana 

 there are only 10 or 11 shields. This is not at all likely to be 

 an individual variation, and hence it is interesting to find the out- 

 lying members of the variety so modified. 



The specimen in question is unfortunately young, as it measures 

 only 47 millim. from the snout to the vent, but in all its other cha- 

 racters it resembles var. tangitana. The dorsal scales are very small, 

 and number 87 across the middle of the body ; there are 18 femoral 

 pores, 8 longitudinal rows of scales on the belly, and the occipital 

 shield is decidedly narrower than the interparietal, all distinctive 

 features of L. ocellata, var. tangitana.

These lizards resemble the specimens of this species from Tangier 

 described by Mr. Boulenger as having the scales very small, obtusely 

 keeled and in 61 to 73 rows across the middle of the body, but in 

 some of them they fall to 56. Their upper caudal scales are also 

 strongly keeled as in specimens from Tangier. The femoral pores 

 vary from 17 to 21, whereas in examples from the latter district they 

 vary from 13 to 19, 17 being the usual number. 



One of the above males is coloured exactly like the specimens from 

 Tangier in the British Museum, but another and two females are 

 less spotted with black, and the white spots on the tail, so marked 

 in Tangier specimens, are absent, or only feebly indicated.
