Head rather large, the difference in size according to sexes not 

 so marked as in L. galloti and its larger allies. Head l.V times as 

 long as broad, its length 4 times in length to vent in males, very 

 little shorter in females ; snout as long as postocular part of head in 

 females, slightly longer in males ; cheeks not noticeably swollen in 

 males. Pileus twice as long as broad. Neck distinctly narrowed. 

 The hind limb reaches the collar or not quite so far in females, a 

 little beyond in males. 



Rostral usually touching the nostril,* separated from the fronto- 

 nasal, which is as long as broad or slightly longer ; frontal a little 

 shorter than its distance from the end of the snout in females, but 

 slightly in males, twice as long as broad (in its narrowest part) in 

 females, slightly longer in males ; parietals as long as or slightly 

 longer, rarely shorter, than the frontal in males, usually a little 

 longer in females, strongly bent down on the temple, occupying the 

 place usually held by the upper temporals , occipital at least as broad 

 as the interparietal, usually considerably broader, and constantly 

 broader than long, on an average longer in males than in females ; 

 supraoculars separated from tlie superciliaries by a series of granules. 

 A single postnasal ; 5 upper labials anterior to the subocular. Tem- 

 poral scutellation granular, often finely, with more or less developed 

 masseteric and tympanic shields ; a series of small upper temporals. 

 Scales covering the lower eyelid extremely small and granidar, those 

 in the centre scarcely, if at all, differentiated. 



33 to 44 scales between the symphysis of the chin-shields and 

 the collar ; gular fold distinct ; collar not serrated, composed of 

 7 to 11 plates. 



Dorsal scales very small, rhombic-granular, more or less distinctly 



which is nearly identical with that of the neighbouring Sahara (Tristram, 

 Urit. Assoc. 1893).
