thau lonrr, outer border strai,i,'ht or concave. First suj^raocular usually 

 divided iuto two, sometimes entire,* rarely disintegrated into several 

 small shields and granules.f as long as or a little shorter thau second ; 

 fourth always replaced by granules, with or without a small shield ; 

 one or two series of granules between the suj^raoculars and the super- 

 ciliaries, sometimes three behind, some of the granules usually 

 penetrating between the first supraocular and the first superciliary ; 

 6 or 7, exceptionally 5 or 8, superciliaries, first longest and in contact 

 with the first supraocular. Anterior loreal;}^ much shorter thau the 

 second ; 4 upper labials, rarely 3 or 5, anterior to the centre of the 

 eye ; subocular sharply keeled below the eye, usually wedged in 

 between the fourth and fifth upper labials, rarely separated from 

 the oral border by a small additional labial or narrowly entering 

 it.§ A large upper temporal, followed by a small one ; temporal 

 scales granular, convex and smooth, upper very minute, lower large ; 

 tvmpanic shield sometimes present, usually absent ; 4 or 5 short, 

 rounded or obtusely pointed lobules form a denticulation in front of 

 the tympanum. 



5 pairs of chin-shields, the 3, or rarely 2, first in contact in the 

 middle ; 23 to 34 gular scales in a straight line between the symphysis 

 of the chin-shields and the median collar-plate, juxtaposed in front, 

 gradually enlarged and imbricate towards the collar ; gular fold absent 

 or slightly indicated. Collar free or attached in the middle, curved or 

 angular, composed of 10 to 13 j^lates. 



Scales granular and smooth, convex or flat, sometimes subimbricate 

 and obtusely keeled on the posterior part of the back, a little smaller 

 on the upper part of the sides, largest towards the ventrals, into 

 which they sometimes gradually merge ; 52 to 68 scales across the 

 middle of the body. Ventral plates in regular longitudinal and 

 straight or somewhat angular transverse series, all except the outer- 

 most broader than long, but not twice as broad as long, or only a 

 few so broad, the series across the middle of the body composed of 12, 

 rarely 14, plates ; 27 to 32 transverse series. 1 to 4, usually 3, 

 unpaired preaual plates, the one in front of the vent usually broader 

 than long. 



15 to 24 femoral pores on each side, the two series meeting or 

 narrowly separated in the middle. Digits with 3 series of scales,

 t One specimen from Alexandria, another from Maryut. 



X Absent on both sides in one specimen from Alexandria, on one side in 

 another.
