The name scutellaius applies to the large,* reticulate or dappled 

 form with very small scales which was first figured from Egypt, and 

 to which I refer specimens from the Siuaitic Peninsula, Palestine, 

 Mesopotamia, and the Algerian Sahara. The following description is 

 drawn up fi'om such specimens. 



Body short and depressed, limbs rather slender. Head H to 

 If times as long as broad, its length 3^ to 4 times in length to 

 vent, its depth equal to the distance l)etween the anterior corner 

 or the centre of the eye and the anterior border of the tympanum ; 

 a more or less distinct lanceolate concavity from the frontonasal to 

 the middle or anterior third of the frontal, ])ounded by very obtuse 

 keels ; snout acutely pointed, about once and a half as long as the 

 postocular part of the head, with sharp canthus and concave loreal 

 region; nasals feebly swollen. Pileus If to 2 times as long as broad. 

 Neck as broad as the head. The hind limb reaches between the collar 

 and the ear, the ear, or between the ear and the eye or, very rarely, 

 the eye in males, the collar, between the collar and the ear. or, rarely, 

 the ear in females; foot 1^ to 1| times as long as the head; foui'th 

 toe, from the base of the fifth, 1 to IJ times as long as the head. 

 Tail H to 1^ times as long as head and body. 



Upper head-shields smooth, flat or feebly convex. Suture between 

 the nasals very short, usually not more than }, rarely i, the length 

 of the frontonasal, which is as long as broad or a little broader 

 than long, as Itroad as or a little broader than internarial space f; 

 prefrontals H to If times as long as broad; frontal shorter than its 

 distance from the end of the snout, 2 to 2^ times as long as broad, 

 rounded or truncate in front, narrow behind ; parietals as long as 

 broad or broader than long, outer border straight or concave ; a 

 small occipital often present behind the suture between the parietals. 

 3 or 4 supraoculars ; first shorter than second, usually entire or 

 accompanied by a granule on the inner side, rarely broken up into
