Body rather strongly depressed, head less strongly depressed than 

 in B. guttulata. Head li to 1^ times as long as broad, its length 4 to 

 41 times in length to vent in males, 4^ to 5 times in females, its depth 

 equal to the distance between the anterior corner of the eye and the 

 tympanum ; snout obtusely pointed, with the nasal plates much 

 swollen, broader than long, as long as or slightly shorter than the 

 postocular part of the head; canthus rostralis obtuse or sharp, 

 loreal region feebly concave; a more or less distinct concavity on 

 the upper surface of the snout, extending to the middle of the 

 frontal shield. Pileus If times as long as broad. Neck as broad as 

 the head. Hind limb reaching the shoulder or the collar in males, 

 the elbow or the axil in females ; foot from but slightly longer 

 than the head to If times its length; toes moderately slender, not 

 or but slightly compressed. Tail not quite twice as long as head 

 and body. 



Upper head -shields convex, smooth or slightly rugose. Nasals in 

 contact with their inner angles behind the rostral, or forming a very 

 short suture (^ to i the length of the frontonasal) ; frontonasal 

 broader than long ; prefrontals as long as broad or a little longer, 

 forming a suture in the middle ; frontal as long as its distance from 

 the rostral or from the end of the snout. If to If times as long as 

 broad, narrow behind ; parietals as long as broad or slightly longer ; 

 interparietal as large as or a little smaller than the frontoparietals, 

 often followed by a small shield ; occipital minute or absent, the 

 parietals often meeting in the middle. 4 supraoculars, first usually 

 rather large, sometimes broken up into 3 or 4 shields, in contact with 

 the frontal,* fourth small and often broken up ; 5 to 7 superciliaries, 

 first largest ; a series of granules, rarely incomplete, sometimes two, 

 between the supraoculars and the superciliaries. Three nasals, lower 

 in contact with the rostral and the first upper labial ; anterior loreal 

 If to 2 times as long as deep, sometimes divided into two, as long as 

 or shorter than the second ; 4 or 6 upper labials anterior to the sub- 

 ocular, which is keeled below the eye, and borders the mouth or is 

 separated from it by one or two additional upper labials detached 

 from its lower part.f Temporal scales small, granular, lower larger ; 

 a narrow tympanic shield; no auricular denticulation. Lower eyelid 

 with a semitransparent disc formed of one large oval scale, which may 

 be broken up into 5 to 8 pieces. 



5 or 6 pairs of chin-shields, the first three in contact in the middle, 



* Except in a female from Tel Jebarah.
