250 THE REPTILES OF EGYPT. 
the time I first asked him regarding the Linnean types, and identified by Mr. Boulenger 
with the Natrix gemonensis, Laurenti. 
Mr. P. J. Smit's notes on the specimen in question mention that the anal is divided, 
that there are 19 rows of scales round the body, and that the specimen has a total 
length of 132 cm., of which the tail forms 37 cm. 
As Mr. Smit made a figure of the specimen, I have reproduced his drawing on the 
above mentioned plate. 
The interest that C. jugularis had to me was the fact that it was one of Hasselquist's 
specimens, and that it was ascribed by Linnaeus to Egypt. No other museum, so far 
as is known, contains a single example of this species from Egypt, and, moreover, I 
have met with only one other reference in literature to its presence in Egypt, namely, 
by Dumeril and Bibron l , who mention that they had seen in Paris a living specimen 
that had been collected in Egypt, and that it was of a beautiful ebony-black colour.

Body long, slender ; head rather narrow ; snout obtuse ; rostral nearly as high as 
broad, little visible on the upper surface of the head ; internasals shorter than the 
prefrontals, equal or nearly equal to them in length ; frontal longer than the distance 
between its outer border and the tip of the snout, slightly narrower or somewhat 
broader than the supraocular, its anterior breadth equal to about two-thirds of its 
length ; parietals considerably longer than the frontal, obliquely truncated posteriorly ; 
loreal oblong ; one prseocular, generally in contact with the frontal ; one subocular ; 
two postoculars; temporals 14-2, 1 + 3, 2-f-2 or 2 + 3 ; eight upper labials, the fourth 
and fifth entering the orbit, occasionally the fifth and sixth ; anterior pair of chin- 
shields in contact with four or five lower labials, posterior pair the longer, separated 
by small scales. 19 rows of smooth narrow scales across the body, each scale with an 
apical pit. 205-218 markedly angulate ventrals ; anal 1/1 ; subcaudals 9S-132. 
Colour greyish or olive-brown above, more or less tinged with reddish ; on the sides 
of the neck and trunk, more especially anteriorly, with sparsely distributed rather large 
dark brown or nearly black spots, margined with whitish or pale yellow ; upper surface 
of the head olive-brown, the nape of the neck with a dark collar broadly margined 
with yellowish, the anterior pale border being continuous with the pale yellowish area
