Of the same size and general characters as the preceding species, to which 
it is very closely allied. ‘The colour seems to be usually of a richer ruddier 
tint, and the black stripe on the face that passes from the eye towards the 
corner of the mouth is generally, but not always, continued downwards on 
to the lower edge of the jaw, thence backwards, bounding the inter-ramal 
area on each side and uniting with the lower end of the stripe that runs from 
below the base of the ear to the throat. In some cases, however, the stripe 
in question stops short behind the corner of the mouth as in 0. beisa. The 
frontal patch and the nose-patch are sometimes entirely separated, sometimes 
joined by a narrow stripe as in O. beisa. ‘The stripes on the body and 
fore legs resemble those of O. beisa, but there is no black patch upon the 
front of the cannon-bone on the fore leg, such as is present in that species.
