Columns as in the preceding table. 



Habitat. — Tunisia, Algeria, and Morocco, North of the Sahara ; up 

 to 1500 metres in the Atlas of Morocco. 



The best combinations of characters for distinguishing the two 

 forms of L. ocellata may be thus contrasted : 



Forma typica. — Occipital rarely narrower than frontal, often broader ; 

 upper postnasal usually in contact with frontonasal; upper temporals, in 

 the adult, with a teel bordering the pileus ; ventral plates in 8 or 10 

 longitudinal series ; 26 to 39 gular scales in median longitudinal series, 

 usually 29 to 35 ; 63 to 80 scales across middle of body ; 11 to 16 

 femoral pores on each side, usually 11 to 14. 



Var. pater, Lat. — Occipital rarely broader than the frontal, often 

 narrower ; first loreal nearly always in contact with frontonasal ; upper 

 temporals usually without keel ; ventral plates in 6 or 8 longitudinal 

 series, very rarely 10 ; 22 to 31 gular scales in median longitudinal 

 series, usually 24 to 29 ; 65 to 100 scales across middle of body ; 13 

 to 22 femoral pores on each side, very rarely 12. 



Section II. G-allotia, Blgr. — Ventral plates in 8 to 20 longitudinal 

 series, transverse series with nearly rectilinear border ; if ventrals in 

 8 longitudinal series, anterior border of ear denticulated ; a single 

 postnasal ; 17 to 33 femoral pores ; 24 to 37 lamellar scales under 

 the fourth toe ; pterygoid teeth present. 



Synopsis of the Species. 



A. Anterior border of ear denticulated; dorsal scales rather large, rhombic 



and diagonally keeled ; 17 to 23 femoral pores ; 24 to 30 lamellar scales 

 tinder fourth toe ; 4 upper labials anterior to subooular. 



44 to 52 scales across middle of body ; ventrals in 8 or 10 

 straight longitudinal and 26 to 30 transverse series ; collar 

 serrated, formed of 6 to 10 plates ; parietals strongly bent 

 down on the temple, which is granulate, without masseteric 

 shield ... . . i. atZawtica, Peters &Doria, p. 111. 



B. Anterior border of ear not denticulated ; dorsal scales minute, granular, 



more or less distinctly keeled ; 23 to 33 femoral pores ; 29 to 37 lamellar 

 scales under fourth toe ; 5 or 6 upper labials anterior to subocular.
