The first example of this Antelope to reach Europe was transmitted to the 
Royal Zoological Museum of Berlin by Werne, a well-known German artist 
and traveller, from the River Sobat in Sennaar. It was characterized as 
belonging to a new species by Lichtenstein and Peters in a communication 
made to the Royal Academy of Sciences of Berlin in 1853, and in the 
following year was carefully described and figured by the same authors in the 
‘Denkschriften’ of the Academy. ‘The type specimen, an adult male, 
remains mounted in the gallery of the Berlin Museum (where Sclater has 
examined it), and is, we believe, that from which the original water-colour 
drawing of Wolf for the accompanying Plate was prepared. 
The next traveller who appears to have met with the White-eared Kob 
was Consul Petherick, who brought home a skin, two heads, and several 
skulls of this species on his return from the Bahr-el-Ghazal in 1859. These 
specimens, which are in the British Museum, were at first incorrectly referred 
by Gray, in his article upon Petherick’s Mammals, to Codus lechee, which, 
however, is quite a distinct species and never ranges nearly so far north. 
Besides the Berlin and British Museums the only other collection that, so 
far as we know, contains a perfect example of this rare Antelope is the 
Royal Museum of Turin. Here, as Count Salvadori kindly informs us, there 
is a fully adult male example of Cobus leucotis mounted in the gallery, and 
standing about 35 inches high at the withers. This specimen was originally 
received alive from the Sudan, along with other animals, by King Victor 
Emmanuel, and on its death was presented to the Turin Museum. 
Heuglin, in 1861, included this species in his list of the Antelopes and 
Buffaloes of North-east Africa, and gave a figure of its head, designating the 
Rivers Sobat and Bahr-el-Ghazal as its localities. It is probable that 
Heuglin’s “‘ Adenota kul” and “ A. wuil,” described as new in the same 
memoir, should also be referred to the present species ; but as the descriptions
