On this ground it is marked with one broad dorsal, and on each side two or three narrower, indistinct black lines. The under jaw, the legs, and the greater part of the tail are entirely black; and there is a whitish spot above and under each of its eyes.

in size, from a trifling projection beyond the remaining teeth to a long and powerful tusk, almost equalling those of the most formidable Carnivora; and from this structure it necessarily follows that a vacant space is left between the incisors and the canines of the upper jaw, and between the canines and the molars of the lower, for the reception and lodgment of those organs when the mouth is closed. The nails of all their fingers, as well as those of the thumbs, are invariably flat and expanded.

The Black Bear of America is distinguished from his fellows, and more especially from the brown bear of Europe, which he approaches most nearly in size and form, by few very striking external differences, except the colour of his fur. His forehead has a slight elevation; his muzzle is elongated, and somewhat flattened above; and his hair, though long and straight, has less shagginess than that of most of the other species of the group. In colour it is of a uniform shining jet-black, except on the muzzle, where it is short and fawn-coloured, becoming almost gray on the lips and sides of the mouth. This, however, it should be observed, is the character only of the full-grown animal: the young are first of a bright ash colour, which gradually changes to a deep[118] brown, and finally fixes in the glossy black tint of mature age.
All these birds were comprehended by Linn?us under the generic name of Strix, but later naturalists have subdivided them into several genera, dependent on the size of the ears and of the ocular discs, on the presence or absence of two remarkable tufts of feathers on the head having somewhat the appearance of horns, and on the covering of the legs and feet. The Virginian Horned Owl is spread over nearly the whole continent of America from north to south. Its plumage is brown above, marked with numerous transverse black stripes, and the feathers of the under surface are of a dirty white, transversely striped with blackish-brown.
