The head is either similar to that of the typical L. muralis, or more 

 depressed, sometimes as much as in the vars. hedriagas and ehalybdea ; 

 its depth equals the distance between the centre or the posterior border 

 of the eye and the tympanum. The hind limb reaches the axil, the 

 shoulder, or the collar in males, the wrist, the elbow, or the axil in 

 females ; foot a little longer than the head. Tail 1^ to a little over 2 

 times the length of head and body. 



Rostral not touching the nostril * ; frontonasal sometimes in con- 

 tact with the frontal t ; frontal as long as or a little shorter than its 

 distance from the end of the snout ; parietals 1^- to If times as long 

 as broad ; occipital usually broader than the interparietal J ; series of 

 granules between the supraoculars and the superciliaries complete or 

 incomplete ; suture between the first and second superciliaries usually 

 oblique, but not rarely vertical ; usually 4 upper labials § anterior to 

 the subocular, which is usually much narrower beneath than above ; 

 temporal scales small ; masseteric shield sometimes large, often small 

 or absent ; upper temporal shields often broken up, the first sometimes 

 in contact with the fourth supraocular. || 



22 to 35 scales between the symphysis of the chin-shields and the 

 median collar-plate, usually 23 to 30 ; gular fold distinct ; collar even- 

 edged, the plates often small, 7 to 12, usually 9 to 11. 



Scales granular, round or oval-subhexagonal, smooth or feebly 

 keeled, 50 to 67 [across the middle of the body, usually 54 to 65 ; 

 36 ( c? ) to 60 (?) transverse series in the middle of the back 

 correspond to the length of the head, 3 and 4 on the side correspond 

 to a ventral plate. Ventral plates 25 to 29 transverse series in males, 



* In contact with the frontonasal in 5 specimens (Ciudad Real, Burbia, 

 Cacabelos and Villa Franca). 



T In 10 specimens (Galicia, Sisargas Id., Cacabelos, Villa Franca). 



X Sometimes twice as broad. Absent in a specimen from Coimbra. Some- 

 times fused with the interparietal or separated from it by a small shield. 



§ 5 on both sides in two specimens from Coimbra, in one from Tlemsen, and 

 in one from Tunisia; on one side in 8 specimens (Sisargas Id., Serra de Gerez, 

 Tamaruth Valley, Fenzou) ; 3 on one side in specimens from Tamaruth Valley. 



II In 21 specimens : Tamaruth Valley (9), Penzou (3), Cacabelos (3), Serra do 

 Gerez (2), Burbia, Villa Franca, Coimbra, Sersou.
