The domestic sheep {Ovis aries Linn.) is not a natural species, but an association of races whose specific origin is obscure. Some authors regard the turf sheep of the stone age of Europe as the ancestor of the domeitic sheep, as forms like it are now living in the Shetland Isles and in Wales. It was of small size, with slender limbs, and erect, short horns. This sheep was supplanted by a curved, large-homed form, the modern domestic sheep. This latter form is pos- sibly the descendant of the Ovisargali Pallas, of Asia, which in North America is represented by the Ovis montana Ouvier, the Rocky Mountain sheep or big-horn (Fig. 530), stiU com- mon on the less accessible summits along the upper Missouri and Yellowstone Eivers, as well as the mountains of Wy- oming and Montana. In the same, though higher and more inac- cessible situations lives the rare mountain goat, Aploceros monta- nus Richardson, whose horns are jet black and polished, slender and conical, like those of the Swiss chamois. It is found sparingly in the higher summits of the Rocky Mountains and the Cascade range ; an individual has within a few years been shot on Mount Shasta, California. Passing by the gazelles and true an- telopes we come to another characteristic American an- imal, the musk sheep {Ovibos moschatus Blainville, Pig. 531), now confined to the arctic regions. A closely allied species, Ovibos priscus of Rutimeyer, formerly during the post-glacial period existed in England, Prance, and Ger- many. Closely allied to the musk sheep is a fossil form (Bootherium of Leidy) which is regarded by Etltimeyer and.
