BONGO ( Boocercus eurycerus ), a West African bushbuck, the largest of the group. The male is deep chestnut, marked on the body with narrow white stripes, on the chest with a white crescent, and on the face by two white spots below the eye. In the East African bongo (B. e. Isaaei ) the body hue is stronger and richer. There is, as yet, no evidence as to whether the females of the true bongo bear horns, though it is probable they do; but as the horns are present in both sexes of the East African form, Mr Oldfield Thomas has made that the type of the genus.'
