 p. 9, 



M. Lataste collected a number of specimens at or near Aumale, in 

 the province of Algiers, which, whilst agreeing with the var. olivieri 

 in the shape of the snout and in the semitransparent palpebral disc, 

 composed of 4 to 6 pieces, differ in the averagely smaller scales, 47 to

 pores, 14 to 17, exceptionally 12 or 13. They should be regarded as 

 a distinct variety. 



Head IJ to If times as long as broad. Hind limb reaching the 

 collar or between the collar and the ear in males, the elbow or the 

 axil in females ; foot l-i- to 1^ times as long as the head. Tail 1|- to 

 If times as long as head and body. 



Frontonasal broader than long ; frontal IJ to 2 times as long as 

 broad ; occipital usually small, often separated from the interparietal 

 by a small shield ; first supraocular usually in contact with the frontal, 

 often broken up into 2 to 4 pieces ; sometimes 2 series of granules 

 between the third supraocular and the superciliaries ; anterior loreal 

 1 J to 2 times as long as deep, sometimes as long as the second ; 4 or 6 

 upper labials anterior to the subocular. Collar free or narrowly attached 

 in the middle. 



The coloration is identical with that of Socotra specimens (var.
