Aipyceros petersi, Boc. P. Z. 8. 1878, p. 741; Huet, Bull. Soc. Acclim. (4) iv. p. 479 
(1887) ; Scl. P. Z. S. 1890, p. 460 (woodcut of head) ; Flow. & Lyd. Mamm. p. 341 
(1891) ; Lyd. Horns and Hoofs, p. 231 (1893). 
Aipyceros melampus, Jent. Notes Leyd. Mus. ix. p. 173 (1887) (?) (Mossamedes). 
Similar, so far as is yet known, to 4. melampus in all respects except 
that on the face, as is shown in our woodcut (p. 26), there is a prominent 
brown patch running along the top of the muzzle. This character is said 
to be perfectly constant, and we therefore admit for the present the validity 
of the Angolan form as a distinct species. 
The Angolan Pallah was first recognized asa distinct species by Prof. J. V. 
Barboza du Bocage, a distinguished naturalist of Portugal, in a list of Angolan 
Antelopes published in the Zoological Society’s ‘Proceedings’ for 1878. 
M. du Bocage based his description upon two specimens forwarded to the 
Lisbon Museum by the weil-known explorer d’Anchieta. Of these the male 
was stated to have come from Capangombe, the female from Humbe— 
two places both in the province of Mossamedes north of the Cunene 
River. M. Bocage distinguished the new species from &. melampus 
principally by its black face, and dedicated it to the late Professor Peters, 
of Berlin, whose opinion agreed with his that it was distinct. It is 
probable that the skull from the Cunene River, obtained by Heer Van der 
Kellen in October 1885, and referred by Dr. Jentink, in his paper on 
Mammals from Mossamedes, to 4. melampus, may belong properly to 
AB. petersi.
