46 Lacertidee. 



The types of this variety are young from Algiers which do not differ 

 in their livery from the typical form. The yellow vertebral streak 

 may be restricted to the nape or extend to the lumbar region, bifur- 

 cating on the nape. Adult often grey or greyish-brown above, some- 

 times coppery brown, with a series of square or transverse black spots 

 on each side of the back, a dorsolateral and a lateral series of round 

 white spots, and between the two latter a series of large blue, black- 

 edged ocelli, which may extend along the side of the tail* ; others are 

 handsomely marked with more or less perfect remains of the light 

 streaks of the young, separated by series of large black spots, except 

 on the vertebral region, which is unspotted ; others again are almost 

 uniform or with mere traces of the dark and light markings.

 Paris, 1909, p. 413, has recorded A. vulgaris from Sokoto, Northern 

 Nigeria (Mission Tilho-Gaillard) ; the young specimen, which I have 

 examined in the Paris Museum, belongs to the var. belli. 



Var. ATLANTICUS, Boulenger. 



I have seen three specimens only, females, from the Atlas of 

 Morocco. They agree with the preceding variety, except that the 

 lower part of the subocular, instead of bordering the mouth, is severed 

 as a small shield intercalated between the fourth and fifth upper 

 labials. 



Suture between the iuternasals | the length of the fronto- 

 nasal, which, in one of the specimens, is longitudinally divided into 

 two. The scales on the body are convex, juxtaposed and feebly keeled, 

 except towards the base of the tail, and there are 52 to 63 across the 



* A thing never observed in any of the Lacerta, in which lateral blue ocelli 

 are frequently present, in the same position on the body.
