" Pale fulvous liver-colour. Forehead with ocular spot and with 

 three or four scarcely oblicjue spots black. Nosg -white. Mane of 

 neck and back long, very deep black. Horns in both sexes strong, 

 rounded at the base, close together, arched and recurved, and annu-

" Sir Samuel Baker has also favoured me with the loan of a leaf 

 from his original note-book, containing a pencil-sketch of the adult 

 male of this species. The elongated mane and the shoulder-stripes 

 are clearly marked in this sketch. 



" A pair of horns, the original specimens figured by Heuglin. are 

 figured [P. Z. S. 1808, pp. 210, 217, figs. Qa and i]. They measure 

 27 inches in length along the upper surface from the base to the 

 tip, and are regularly annulated up to about inches from the tip, 

 the annulations being about 27 or 28 in number. Upon comparing 

 them with horns of Hippotragus eqitinus in the British iluseum and 

 the collection of the Royal College of Surgeons, I find the dift'erences, 

 as might have been expected, very small. But, judging from the 

 single pair before us, the horns of the northern species appear to be 

 much more massive, especially at the base, and not quite so long, and 

 to have the tips diverging instead of slightly converging. This latter 

 character may perhaps vary in individuals. 



" As regards the general external appearance of Baker's Antelope, 

 it would seem to be readily distinguishable from the Equine Antelope 

 by the pale fulvous colour, the pencilled ears, and the black stripes 

 over the shoulders, which, although not distinguishable in the young
