are very meagre and, so far as we know, no specimens of these problematical 
species are extant, this must remain a matter of some uncertainty. 
Since Heuglin’s time several other African explorers have met with this 
Antelope, but we are not aware that, with the exception of Sir Samuel Baker, 
they have brought home specimens. In the Appendix to ‘Ismailia,’ Sir 
Samuel placed the name of the present species in the list of animals met 
with in the Shooli country on the Upper Nile, and Sclater (who examined 
the specimens brought home by Baker) believes that there were some heads 
of this Antelope amongst them. MHarnier’s description of an Antelope 
obtained in March 1861, during his voyage up the White Nile (Reise, p. 52, 
1866), is apparently referable to Cobus leucotis. Dr. Schweinfurth, in ‘Im 
Herzen von Afrika,’ mentions Antilope leucotis in several places, and in his 
first volume gives fairly accurate woodcuts of the heads of both sexes. On 
the lower flats of the rivers of the Niam-Niam country, Dr. Schweinfurth 
found this Antelope by far the commonest species in the dry season, being 
met with in large herds of from 100 to 500 individuals. During the rainy 
season, he tells us, it resorts to the higher forest-bushes and separates into 
small troops for pairing. He also mentions as a peculiarity of this elegant 
animal that when running away it springs up into the air after the manner 
of the South-African Spring-buck, and shows its white rump. The flesh 
of Antilope leucotis, he tells us, is one of the best for culinary purposes. 
The female he describes as being very like that of Cervicapra arundinacea, 
but recognizable at once by the black on the front limbs. 
Emin, in his ‘ Reise-briefen,’ refers in several passages to Antilope leucotis 
as met with on the Upper Nile. Dr. W. Junker, in his ‘ Travels in Africa,’ 
records the capture of a “ Kala Antelope, Antilope leucotis,’ as far south as 
the Upper Welle (about 3° 30’ N. lat.), near Mount Madyanu, and gives a 
figure of it in his text. Looking to this and to what Dr. Schweinfurth has 
told us, we must assume that the present Antelope extends beyond the water- 
parting of the Nile and Congo down to the banks of the Welle.
