Taking Antilope silvicultrix, Afeelius, and A . mergens, Blain., as the typical species of a
group, we shall find no difficulty in extending it by an addition of several other species of
African origin, which, both in respect of physiognomy and general characters, manifest such
a -striking similarity to the typieal species, that persons the least accustomed to judge of
resemblances, will scarcely even find a difficulty in indicating them. Hence Cephabpus
must be regarded asu. regular and natural group, and one likely to „stand when those instituted
upon characters, deduced from the mere modifications presented by aberrant species, will
require to be discarded. The little animal we have here described, under the name of Cv
Natalensis, is clearly entitled to a place in the group in question; and though both it and
Antilope carulea (H. Smith), have certain characters peculiar to themselves, yet they have all
the requisites essential to rank them in the genus Cephdlopns. In both of these species the
female as well as the male is always furnished with horns, and in this respect they differ
from the other species of the group which occur in South Africa,—the females o f which are
almost always found without horns, yet individuals are occasionally killed in which they exist ;
hence it would appear that their presence or absence ought not to be highly considered in
establishing the generic characters. Both C. carulea and C. Natalensis inhabit the African
forests; the former towards the Cape of Good Hope, the latter to the eastward about and
beyond Port Natal. They both feed partly upon the grass which occurs among the underwood,
and partly upon the young leaves and shoots of the brushwood and small trees which exist in
the situations they inhabit; and to obtain the latter they may occasionally be seen scrambling
among shrubs, or ascending the stem o f sloping trees, so as to reach what they cannot attain
while they are on the ground.
