DESCRIPTION OF 
No. XIII. 
coluber;. 
Abdominal Scuta 17 4] 
[322. 
Sub-caudal Squama I 4 8 J 
Called by the natives Botla Passeriki. 
This snake agrees exactly in most circumstances with the one last described. The head 
considerably thicker than the neck, oblong, depressed above, rounded on the sides, and 
contracting at the eyes, is lengthened into a long, straight, angular, pointed rostrum, which 
resembles the beak of a bird, with a small, soft, obtuse, reflex, process, at the extremity. 
The occiput is covered with sub-orbicular, imbricate, scales; the crown and rostrum with 
eleven laminae: of which, the two anterior are pyramidal, rounded at the base; the next 
pair nearly of the same form, but larger; next, a small pair sub-triangular; the central 
lamina between the eyes, spatulate, those on the side, conical; the posterior pair, semi- 
cordate. 
The mouth wide; the upper jaw a little longer than the lower, the scale in front not 
emarginate. The teeth reflex, slender, sharp; the anterior, in both jaws, less close, thicker, 
and longer: a marginal row, in the upper jaw, and two palatal rows. 
The eyes lateral, large, oval, prominent; of a golden colour. The nostrils small, on the 
side of the rostrum near the apex. 
The trunk somewhat triangular; the scales linear-lanceolate, except on the carina of the 
back, and in the row on each side of the scuta, where they are broacl-oval. On the neck 
and fore part of the trunk, they are loose, and only contiguous; on the rest, close, imbricate. 
The length four feet one inch ; the circumference of the neck one inch and a quarter, that 
of the trunk, where thickest, two and a half. The tail, round, very slender, covered with 
ovate, imbricate, scales, tapers to a sharp point: in length, one foot six inches and a third. 
The colour. The head, as in the former, seems as if covered with green velvet; the lips 
and sides of the throat of a deep yellow. The trunk and tail of a fresh grass-green, with a 
white fillet intersected by orange lines, running along the edge of the scuta, on each side of 
the anus, and down half the tail along the edge of the sub-caudal squamae. The variegation 
of colours, when the animal is enraged, is much more conspicuous in this than in the former 
snake, and is produced in the manner already described; but remains in some degree visible 
even in the dead animal, the black scales being more numerous, and the margins of more of 
the green scales being either black or white. An attempt has been made to represent it in 
the drawing, from a living subject. 
A most striking difference may be remarked in the colour of the belly and under part of
