1911 Encyclopædia Britannica/Udad

UDAD, Aoudad or Audad, the Moorish name of the Barbary sheep, or arui, Ovis (Ammotragus) lervia, the only wild sheep found in Africa, where it inhabits all the mountain ranges of the north, descending to the eastward far into the heart of the Sudan. The udad is distinguished by the abundant hair on the throat and fore-quarters of the rams, and the length of the tail. In the absence of face-glands and in the structure of the horns the species approximates to the goats. The “lion-coloured” coat approximates to the hue of the limestone rocks on which these sheep dwell.
