CIO ZOOLOGY. the Shetland Isles and in Wales, size, with slender limbs, and erect, short living in connects the deer family with the BovidcB, represented by the sheep, goat, antelope, gazelle, and ox. The domestic sheep {Ovies 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 domestic sheep, as forms like it are now It was of small horns. This sheep was supplanted by a curved, large-horned form, the modern domestic sheep. This latter form is pos- sibly the descendant of the Ovis argali Pallas, of Asia, which in North America is represented by the Ovis montana Cuvier, the Kocky Mountain sheep or big-horn (Pig. 530), still com- mon on the less accessible summits along the upper Missouri and Yellowstone Eivers, as well as the mountains of AVy- oming and Montana. In the same, though higher and more inac- cessible situations lives the rare mountain goat, Ajjloceros monta- nus Kichardson, 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 Eocky 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 Eiltimeyer, 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 Eiltimeyer and.
