In this family the most remarkable genera are undoubtedly the Martens, the Polecats, the Gluttons, and the Otters.
The Martens of the North are cousins-german of the weasels, so justly feared by our farmers and villagers on account of the extensive depredations which they commit in the poultry-yard. The martens are not less ferocious; but in the fir and birch forests which they inhabit, it is upon the small rodents, the birds, and, when necessity prompts, upon the reptiles, that they exercise their sanguinary tyranny. They scale trees as nimbly as cats; and their flexible body enables them to introduce themselves into the smallest openings, where a cat could not pass, and into the burrows and fissures of the trees or rocks which serve as an asylum for their victims. They are, moreover, very pretty animals, with lively manners, a cunning physiognomy, and a rich furry attire. Besides the ordinary marten, which is found in all the north of Europe, zoologists distinguish in this genus several species exclusively indigenous to the coldest regions of the two continents. The most renowned for the beauty of his coat is the Zibelline, or Sable, which we must look for in Northern Russia and Siberia. Its hairs, whose general shade is a grayish-brown, possess this singular property, which distinguishes them from every other kind of fur—they have no particular inclination, and consequently may be laid down indifferently in any direction whatever.
The genus Polecat (Mustela putarius) comprehends the smallest of all known Carnivora—the Weasel, the Ferret, and the Ermine. The temperate countries of Europe possess one variety of the latter species; but the ermines of the extreme north have a much fuller and softer fur. These animals, like many others, change their garb according to the season. The ermine, which poets have adopted as the emblem of purity, on account of his spotless whiteness, in reality only merits that dangerous honour in the winter; it is then only that he assumes that immaculate robe which the proudest monarchs are content to wear. In summer its colour is a clear maroon. His tail alone remains at all times of a beautiful shining black.
The Glutton (Gulo Arcticus) is a carnivorous quadruped of a very voracious nature, about the size of a large badger, between which and the polecat he appears to form a link. His legs are short and robust; he has a compact body, large head, and unwieldy gait. His ears are small; his tail is short and tufted. His skin is a black brown on the top of the head and back; a white line extends along each flank, from the shoulder to the root of the tail. The muzzle is black; the remainder of the body a deep brown. Like most of the mammals of the Polar region, he has two kinds of hair—the upper long and coarse, the lower soft, fine, and of an uniform brown colour. The glutton owes his name to his extreme voracity. He does not fear to attack animals of the size of the reindeer; he leaps upon them, fastens his claws in them, rends them to pieces, until at length they fall exhausted. After having gorged himself on their flesh and blood, he hides the remainder for another repast.
The genus Otter (Lutra vulgaris) comprehends several species, distributed over nearly all the countries of the world. I shall here speak only of the Otter of Kamtschatka, or Sea Otter (Enhydra lutris), so named on account of his essentially aquatic habits. He weighs from seventy to eighty pounds. In full season his colour is perfectly black; at other times, of a dark brown. He attains the length of three feet, including his tail; has hind-feet resembling those of a seal; the upper jaw is armed with six, and the lower with four incisors. The grinders are broad, and well adapted for crunching crustaceous animals. He runs with great rapidity, and swims with astonishing ease and swiftness. Of late years, however, he has been the object of so murderous a chase on the part of the Russian and American hunters that he has almost disappeared from the Polar shores. The skins of the sea otter are much prized by the Chinese, who pay for them from seventy to one hundred roubles a-piece. Very few ever reach the European market.
Among those Carnivora which are able to accommodate themselves to the severest climates, I may mention the Foxes. These animals attire themselves, under the Polar latitudes, in a fur of sufficient thickness to endure the intense cold they are required to support; and this fur is esteemed among the most precious varieties, under the names of Isatis skin, White Fox, Black, Blue, and Tricoloured Foxskins. The shades vary according to Reynard’s habitat, his age, and also the season; they correspond in like manner to the differences of race, but not to the differences of species. The most valuable skins are obtained from those foxes which belong to very cold countries; and it seems that as they recede from a certain latitude, they lose their value. “Some Blue Foxes were killed by our hunters,” says Madame Léonie d’Aunet, “which were stunted and ugly. The Spitzbergen foxes do not in any respect resemble the foxes of Iceland or Siberia, whose fur is so beautiful and in such high repute. That they may be thoroughly protected from the cold, they do not wear upon their bodies a fur so much as several thick folds or layers of very thick hair, so intermingled and threaded that it is rather a mattress than a coat of fur. Moreover, instead of being of a somewhat tawny colour, like the Iceland foxes, they are of an ashen-gray. Their skin, nevertheless, is excellently adapted for making carpets.”
I see no intermediaries between the small Carnivora we have just passed in review, and the formidable tyrant of the icy Deserts, the Polar or Marine Bear (Ursus marinus), popularly known as the White Bear; an improper appellation, as it confounds the Bear of the Arctic Seas with the Albino variety of the Common Bear.
The former constitutes a perfectly distinct species, whose characteristics, apart from the yellowish-white colour of his rich soft fur, are a flattened and elongated head, a long neck, high legs, and feet whose conformation is admirably adapted to the habitat and amphibious existence of the animal. In fact, the sole of each foot is garnished with a thick fleece, which permits the Arctic bear to walk on the ice as on a carpet, and the toes are connected by a membrane which renders them eminently fit for natatory purposes.
