differences which are quite easily seen between this animal and Cephalophus harveyi 
according to the descriptions found in the literature. My specimen may be described 
as follows: 
Fur close, fine and glossy with the hairs of the back measuring 20—27 mm.' 
General colour rich chestnut red, fading below to rufous. The black blaze on the 
forehead extends from the muffle to the coronal tuft; on the nose it is about 17 mm., 
but widens to twice that in the interocular region. The greater and central portion 
of the tuft is mahagony, but the lateral parts are rufous. Eye-brows and sides of 
the face rufous. The black central stripe is continued on the nape behind the ma- 
hagony-coloured tuft and is then dissolved in the mixed black and chestnut red of 
the upper neck which extends to above the shoulders, Chin dusky anteriorly, but 
behind this part it is whitish, gradually blending into the buff throat and rufous 
lower neck. Kars white inside and blackish outside, behind them a nearly naked 
black area on either side of the black stripe of the nape. Fore legs glossy brownish 
black. Hind legs rufous to chestnut red but from above the hocks and down to the 
hoofs glossy brownish black. The tail has basally the colour of the back, on the 
posterior half some whitish hair are mixed in, and the terminal well developed tuft 
is proximally black, terminally white, with some rufous hairs mixed in. An ill-defined 
dark brown streak extends over the chest mesially but disappears near the navel. 
The hoofs measure about 37—38 mm. in total length. 
The type locality of Cephalophus harveyi is Kilimanjaro, and the type-specimen 
has been pictured in »Book of Antelopes» (Vol. 1, Pl. XVII). The Kenia specimen 
differs a great deal from this coloured plate quoted, especially by its mahagony, not 
black, coronal tuft, and much darker legs and feet. When Trur communicated a 
description® of this Duiker from Kilimanjaro he stated that the tuft is »black», and 
the forelegs are said to be »entirely dusky». This description evidently agrees with 
the type specimen in British Museum, because it is termed »excellent> by the authors 
of the » Book of Antelopes». In the year 1903 Tuomas described C. ignifer from Eldoma 
Ravine and stated then that C. harveyi had »no chestnut coronal tuft«. LypEKKER 
emphasizes again in his book »The Game Animals of Africa»*, as Tuomas before, that 
Harveys Duiker is distinguished from Cephalophus ignifer »by the black forehead and 
the absence of chestnut in the head-tuft». The tail of the typical specimen of Cepha- 
lophus harveyi as represented on the plate in »Book of Antelopes» is quite unlike this 
organ in the present specimen. This may, however, be due to on error committed 
by the artist, because the Natal Duiker on Pl. XVI of the same work has been 
pictured with a tail equally hairy along its whole length, although, as I have stated 
on typical specimens from Natal in this museum, the tail of the Natal Duiker is thin 
basally and carrying a terminal tuft, just as this organ is represented in C. nigrifrons, 
and C. ogilbyi on Pl. XVIII of the work quoted. 
' It is quite probable that specimens living at a higher altitude on Kenia will prove to have somewhat 
longer hair.
