Tliis variety, avIucIi is only kuowu from Tangier and the Portuguese 

 province of Algarve, differs but little from the typical form, the 

 principal distinction lying in the smaller scales and the absence of a 

 dark vertebral streak or series of spots, the latter feature being shared 

 by the two following varieties and several others from S.W. Asia. 



Head rather short, not more than It] times as long as broad, and 

 moderately depressed, its depth equalling the distance between the 

 anterior corner of the eye and the tympanum. Hind limb reaching 

 the shoulder in males, the elbow in females ; foot 1 J to 1| times the 

 length of the head. Tail 1| to 2 times as long as head and body. 



Head-shields as in the typical form, but parietals rather shorter, 

 usually but little longer than broad ; series of granules between the 

 supraoculars and the superciliaries complete, or first superciliary in 

 contact with the second supraocular ; parietal in contact with the 

 upper postoculax"* ; 4 upper labialsf anterior to the subocular, which 

 is narrower beneath than above ; massetei'ic shield present. + 



Scales finely granular, distinctly keeled, 61 to 76 across the middle 

 of the body ; 36 to 57 transverse series, iu 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 in 24 to 27 transverse series iu 

 males, 30 to 32 in females. § Preaual shield moderately large, 

 bordered by one or two semicircles of small shields.

 19 femoral pores on each side.|l 23 to 28 lamellar scales under the
