to a “real Antelope” and that he hoped shortly to “ have an opportunity of 
describing it in detail under the name of Antelope doria.” 
Some two years later the late Dr. Gray proposed the name “ Antilope 
zebra” for the same animal, based upona skin received by the British Museum 
from Sierra Leone. Gray recognized it as being evidently the same as that 
previously described by Bennett, and gave no reason for proposing to alter 
its name. 
About the same time similar imperfect flat skins attracted the attention of 
M. Robert, of Paris, who shortly described them in a communication to the 
‘Echo du Monde Savant’ of 1836 under the name Antilope zebrata. But 
there is no doubt, we think, that “doria” was the first published specific 
appellation of this Antelope, and ought to be adopted. “Doria” is 
stated by Gray (Cat. Ung. p. 129) to have been the Christian name of 
Mr. Ogilby’s wife. 
In his ‘ List of Specimens of Mammals in the British Museum,’ published 
in 1845, Gray assigned this species to the genus Cephalophorus, i. e. Cepha- 
lophus. In his subsequent Catalogues he transferred it to the genus Damalis 
(i. e. Damaliscus), “ on account of the dark mark on the outside of the limb.” 
From the flat skins in the British Museum and the Zoological Society’s 
collection, Fraser, in 1849, gave a partly imaginative figure of this Antelope 
in his ‘ Zoologia Typica.’ 
It was more than 50 years after the imperfect description of this problem- 
atical Antelope from the flat skins before science obtained correct information 
as to its proper characters and position in the system. 
During the celebrated expedition of the naturalists of the Leyden Museum 
to Liberia in 1879 and following years Mr. Biittikofer first obtained perfect 
specimens of this Duiker on the St. Paul’s River. ‘These were described by 
Dr. Jentink in the seventh volume of the ‘ Notes from the Leyden Museum ’ 
in 1885, and a figure was given of the skull. In the succeeding volume of 
the ‘ Notes’ Dr. Jentink gave fuller particulars respecting this welcome re- 
discovery, and informed us that, as shown by the series of specimens collected 
by Mr. Biittikofer and his fellow travellers, this Antelope is not uncommon 
in certain parts of Liberia. The “ Mountain-deer,” as the Americanized 
Liberians call it, does not occur in the coast-district, but is found in 
the mountainous terrain of the interior. Dr. Jentink gave coloured 
illustrations of the male, female, and young of this Antelope, together with
