Angolas, of the same region, famous for the quality of
their wool--not to be confounded, however, with the Angora wool, which
is the produce of a goat. There are sheep in Tartary that eat bones
like dogs, and in Hindustan and Nepaul there are kinds that have four
horns each. These are the Dumbas. A little species exists in Iceland,
in which the horns sometimes grow to the number of eight--though four is
the more common number. America, too, has its varieties. These are the
Brazilian sheep, the Demerara breed, the South American sheep, and a
variety known as the West Indian.

In fact, go to whatever part of the world you may, you will find a
species or variety of this valuable animal, different in some respects
from all the others.

The _wild sheep_, like the wild goats, do not number a great many
species; but there are certainly several that are yet undescribed, and
perhaps there may be about a dozen in all. No doubt the great central
mountains of Asia, and also the ranges of Northern Africa, still
unexplored, will in time yield several new species of wild sheep.
Indeed, late travellers in the Himalayas speak of wild sheep that appear
to be essentially different from the _argali_, and other species already
known.

One species of wild sheep belongs to Europe--the Moufflon, which is to
this day found plentifully in the mountainous parts of Corsica, Cyprus,
and Candia. It was supposed to be the original of the tame breeds; but
this is a mere conjecture.

In America there is also but one species of wild sheep, though it has
also a variety. This is the Bighorn of the Rocky Mountains, lately much
spoken of by prairie travellers and fur-hunters. It is not known in
tropical North America, nor does its range extend to the Andes of the
south; but it is found to the west, in the mountains of California, in a
variety called the Californian sheep. The bighorn is extremely like the
Asiatic argali, and was for a long time regarded as identical with the
latter; but this was an error. It is now ascertained that not only is
the American animal of another species, but also that there are several
distinct species of the argali itself in the different ranges of Asiatic
mountains.

Africa has its wild sheep, but only in its northern parts. This is the
Aoudad, which dwells in the mountains of Barbary.

Asia appears to be the head-quarters of the wild sheep. One species is
found in Armenia, and another in the Caucasus. Sib
