ZAMENIS EOGEESI. 
255 
Body elongate, somewhat shorter and stouter than Z. rhodorhachis ; head also slightly 
broader and snout less pointed ; depth of the rostral equals about half of the 
breadth, the portion visible from above equals about one-third of the interval between 
the rostral and the frontal ; internasals as long or nearly as long as the prefrontals, 
quadrangular, the anterior borders more or less rounded, or anteriorly and externally 
divergent ; prefrontals sometimes confluent ; frontal considerably longer than its 
distance from the end of the snout, its anterior breadth about three-quarters of its 
length, sides deeply concave, in contact slightly with the preocular ; parietals rather 
broad, their extreme length nearly equalling the conjoint frontal and prasfrontals ; supra- 
ocular one-third narrower than the anterior border of the frontal ; loreal longer than 
deep; one prseocular ; one subocular, rarely two; two postoculars ; temporals 2 + 2, 
rarely 2 + 3 ; nine upper labials, the fifth and sixth entering the orbit, occasionally only 
the sixth. Scales smooth, in 19 rows. Ventrals 197-21, feebly angulate; anal 1/1 ; 
subcaudals 95-106. 
General colour greyish or yellowish ; a longitudinal dorsal series of about 60, olive- 
brown, rounded spots along the two anterior thirds of the body, more or less confluent 
posteriorly in some, alternating in lateral series of smaller spots close to the angles of 
'the ventrals ; the posterior third of the body and the tail uniform yellowish. Head 
uniform brown above, with a dark oblique temporal band and another behind it, a 
black spot below the eye and another behind the nostril ; the areas between these 
four dusky markings are more or less bright yellowish orange. Under surface 
yellowish white. A dusky spot occupies the angle of every third or fourth ventral, 
and there are occasionally a few obscure small dusky spots between the angles of the 
ventrals and their keels. 
It attains to a length of 845 millim., of which the tail forms 220 millim. 
It has hitherto been recorded only from Lower Egypt, and from the most western 
part of its sea-board, viz. Marsa Matru.
