At the present day it is extinct everywhere, excepting in the eastern parts of Arctic America, not going west of the Mackenzie River nor south of Labrador.

It is also found in Greenland.] "The musk ox, when full grown, is as large as the generality of English black cattle; but their legs, though thick, are not so long, nor is their tail longer than that of a bear; and, like the tail of that animal, it always bends downward and inward, so that it is entirely hid by the long hair of the rump and hind quarters.

The hunch on their shoulders is not large, being little more in proportion than that of a deer.

Their hair is in some parts very long, particularly on the belly, sides, and hind quarters; but the longest hair about them, particularly the bulls, is under the throat, extending from the chin to the lower part of the chest between the fore legs.

It there hangs down like a horse's mane inverted, and is fully as long, which gives the animal a most formidable appearance.
