The forest region, and especially its coniferous portion, though it has lost some of its representatives within historic times, is still rich. The reindeer, rapidly disappearing, is now met with only in Olonetz and Vologda; the _Cervus pygargus_ is found everywhere, and reaches Novgorod. The weasel, the fox and the hare are exceedingly common, as also the wolf and the bear in the north; but the glutton, the lynx, and even the elk are rapidly disappearing. The wild boar is confined to the basin of the Dwina, and the _Bison eropea_ to the Bielovyezha forests. The sable has quite disappeared, being found only on the Urals; the beaver is found at a few places in Minsk, and the otter is very rare. On the other hand, the hare and also the grey partridge, the hedgehog, the quail, the lark, the rook, and the stork find their way into the coniferous region as the forests are cleared. The avifauna is very rich; it includes all the forest and garden birds which are known in western Europe, as well as a very great variety of aquatic birds. Hunting and shooting give occupation to a great number of persons. The reptiles are few. As for fishes, all those of western Europe, except the carp, are met with in the lakes and rivers in immense quantities, the characteristic feature of the region being its wealth in _Coregoni_ and in _Salmonidoe_ generally. In the Ante-Steppe the forest species proper, such as _Pteromys volans_ and _Tamias striatus_, disappear, but the common squirrel, the weasel, and the bear are still met with in the forests. The hare is increasing rapidly, as well as the fox. The avifauna, of course, becomes poorer; nevertheless the woods of the Steppe, and still more the forests of the Ante-Steppe, give refuge to many birds, even to the hazel-hen, the woodcock and the black-grouse. The fauna of the thickets at the bottom of the river-valleys is decidedly, rich and includes aquatic birds. The destruction of the forests and the advance of wheat into the prairies are rapidly impoverishing the Steppe fauna. The various species of rapacious animals are disappearing, together with the colonies of marmots; the insectivores are also becoming scarce in consequence of the destruction of insects, while vermin, such as the suslik (_Spermophilus_), become a real plague, as also the destructive insects which have been a scourge to agriculture during recent years. The absence of _Coregoni_ is a characteristic feature of the fish-fauna of the Steppes; the carp, on the contrary, reappears, and the rivers are rich in sturgeons. On the Volga below Nijni Novgorod the sturgeon, and others of the same family, as also a very great variety of ganoids and _Teleostei_, appear in such quantities that they give occupation to nearly 100,000 people. The mouths of the Caspian rivers are especially celebrated for their wealth of fish. _SIBERIA_ _JEAN JACQUES ELISEE RECLUS_
