Kouseband of the Cape Colonists. 
Individuals of this species are found in all parts of Southern Africa. 
ELAPS DORSALIS, n. s. 
Head quadrangular, scarcely if at all wider than the neck; nose rounded. Body slender, sub- 
cylindrical, and of equal thickness, being rather more than a line in diameter. Tail cylindrical, 
rather more slender than the body, and tapered towards the apex, which is formed of a horny spine. 
Nostril situated in the anterior part of the nasal plate. Scales of body rhomboidal, or slightly six- 
sided. First pair of submental plates truncated behind, second pair truncated in front, pointed behind ; 
the inner sides oblique. The upper and lateral parts of the head, body, and tail, deep liver-brown, 
with a narrow reddish yellow line along the back from the nose to the apex of the tail ; under parts 
intermediate between sienna-yellow and cream-yellow. Rows of scales on the body 15 ; abdominal 
plates 219. Subcaudal scales 28 pairs. Length from nose to base of tail, 9£ inches; length of tail, 
1 inch 1 line. 
Inhabits Kaffirland, and the country towards Port Natal. 
This is distinct from Elaps Hygece, butvery closely allied to it. The latter presents many 
varieties, but I have never found one of them so long and so slender, nor one which had the first pair 
of submental plates truncated posteriorly. In all the species of Elaps Bygece which I have examined, 
the plates mentioned were pointed behind, and prolonged considerably beyond the anterior edge of the 
second pair.

latonia, Baud. Rept. tom. vii. page 156. Naja lubrica, Schleg. Essai sur la Physionomie des 
Serpens, part descript, page 482. Nacht Slang of the Cape Colonists. 
Inhabits Southern Africa, more particularly towards Cape Town. It moves about principally 
in the evening, or during the nig'ht, hence the Colonists call it Night fenake.

This species is widely distributed over Africa. Individuals are frequently found in the Cape 
Colony, and I have seen others from the Gold Coast, Sierra Leone, and the Gambia.

Colonists. 
Individuals of this species have been observed in all the districts of Southern Africa which have 
been visited by Europeans. I have also seen specimens which were obtained on the Gold Coast, and 
others which were found to the northward of Sierra Leone.
