This species ranges from the northern states of Mexico to northern British Columbia and it culminates (i. e., reaches its finest development) in southeastern British Columbia. In Northwest Alaska other related species occur. A female specimen from southeastern British Columbia was exhibited in the Zoological Park during 1905 and 1906, and in 1902, a male specimen of a closely related species (_Ovis nelsoni_) was also here. As opportunities offer to procure male specimens, that have been kept in their home region until they are at least a year and a half old, they will be purchased and exhibited. The Mouflon, (_Ovis musimon_), or Wild Sheep of Sardinia, is represented by a fine pair of specimens presented by Maurice Egerton, Esq., of London, and a young male born in the Park. The female of the adult pair was captured when a lamb in the mountains of Sardinia by Mr. Egerton. The ram of this species is handsomely colored, and this specimen is noted for his friendliness, and his fondness for admiration. The Arcal Mountain Sheep, (_Ovis cycloceros_), is one of the smallest mountain sheep of India of the “big-horn” type (with circling horns). The fully adult male, with its long undermane of coarse, shaggy hair and proud postures, is a very noteworthy creature. This species inhabits the mountains of northern India, Tibet, Afghanistan, Beluchistan and southern Persia. The Burrhel, or Blue Mountain Sheep, (_Ovis burrhel_), also of northern India, is of quite a different mould from the preceding species. Its countenance has almost a benign expression, and its curious out-pointing horns, of large size give it a most jaunty air. By some it is regarded as the most beautiful of all mountain sheep. In size, however, it is not imposing, for it is one of the smallest species. It is not so hardy as the preceding species, and there may be periods when there are no specimens on exhibition. The Aoudad, or Barbary Wild Sheep, (_Ovis tragelaphus_), comes from the hot, dry mountains of northern Africa, and it endures the cold, wet climate of New York in a manner sufficient to put to shame our American mountain sheep, goat and other western ruminants. The largest male Aoudad of our herd is a very fine specimen of its kind. He is as fond of admiration as any peacock, and often poses in striking attitudes on the highest point of his rocks. He was born here on March 19, 1902.
