As the settlements increased in Tasmania, and the ground became cleared, the animals were driven from their haunts near the town to the deeper recesses of the forests yet unexplored. They were easily procured by setting a trap in the most unfrequented parts of the woods, baited with raw flesh, all kinds of which they will eat indiscriminately and voraciously. They also, it is probable, prey on dead fish and blubber, as their tracks are frequently found on the sands of the sea-shore. In a state of confinement they appear to be untamably savage, biting severely, and uttering at the same time a low yelling growl. A male and female which Mr. Harris kept for a couple of months, chained together in an empty cask, were continually fighting. Their quarrels began as soon as it was dark, as they slept all day, and continued throughout the night almost without intermission, accompanied by a kind of hollow barking, not unlike that of a Dog, and sometimes a sudden kind of snorting, as if the breath were restrained a considerable time and then suddenly expelled. They frequently sat on their hind parts, and used their fore paws to convey food to their mouths. The muscles of the jaws were strong, and they crushed the largest bones asunder with ease. This Dasyure, like the others of the genus, has the incisor teeth equal, and there are eight of them in the upper jaw and six in the lower. The four canines are large, and there are two powerful premolars in each jaw and on each side. These are succeeded by four molars above and below, and on both sides of the mouth. The incisor teeth, equal in size, are arranged in a semicircle in the upper jaw, and those of the lower jaw have a corresponding direction, but they are rather the stouter. The canines are well developed, and those of the lower jaw bite in front of those of the upper. They look eminently adapted for stopping and seizing prey, and their carnivorous character is surpassed by that of the premolars and true molars. These last have a triangular grinding surface: the first has four sharp cusps, the second and third have five, and the last, which is the smallest in the upper jaw, has only three. In the lower jaw the last molar is of the same size as the last but one, and has four cusps; and the other molars have much resemblance to those in the upper jaw. The hind feet have the toes separate and not united by a fold of skin, and there is a rudimentary great toe in this species. The condyle of the humerus is not perforated--as in the Kangaroos, for instance--for the passage of the blood vessels, but is whole, and the outside of the bone is marked by a groove, along which they pass.
