At the present time the musk sheep, the elegant white arctic fox, the reindeer, and the glutton or wolverine (Fig. 21), live side by side in circumpolar America, and the three last range over the far north of Asia and Europe, the glutton, according to Zimmermann, having been caught as far south as Brunswick and Saxony. Of these the first two have been met with as far to the south-west as the Pyrenees; the third as far to the south as Switzerland; and the fourth as far to the west as the caves of Somersetshire, and to the south as Auvergne (E. Lartet).
