1. Length from snout to vent (in millim.). 2. Number of scales across 

 middle of body. 3. Transverse series of ventral plates. 4. Number of plates 

 in collar. 5. Number of gular scales in longitudinal series. 6. Number of 

 femoral pores (right and left). 7. Number of lamellar scales under fourth toe. 



Habitat. — Of all species of Lacerta, known from more than a few 

 specimens, this was long believed to have the most restricted habitat, 

 having been found only in the town of Oran and its vicinity. It has, 

 however, recently been recorded from Teluet, on the Atlas near the 

 city of Morocco, by Chabanaud. 



Although quite isolated in the genus Lacerta this species is probably 

 derived from the Section Podarcis ; by appealing to the genus Eremias 

 (Section Mesalina) we can easily imagine the missing links — enlarge- 

 ment of the central scales of the lower eyelid accompanied by greater 

 and greater translucidity and ultimate fusion of the same, division of 

 the ventral plates resulting in an increase in the number of longi-. 

 tudinal series. As usual in the Section Podarcis, the two postfrontal 

 bones are distinct.
