Mr. Harris, who was the first to make this animal known, states that it lives among caverns and rocks, in the deep and almost impenetrable glens, in the neighbourhood of the highest mountains of Van Diemen’s Land. The specimen from which his description was taken was caught in a trap baited with Kangaroo’s flesh; it remained alive but a few hours, having received some internal hurt whilst being secured. From time to time it uttered a short guttural cry, and it appeared exceedingly inactive and stupid, and, like the Owl, had an almost continual motion of the nictitant membrane of the eye. Remains of an Echidna were found in the stomach of the animal. Waterhouse states, on the authority of Mr. Gunn, that these animals are common only in the remoter parts of the colony, and used to be frequently caught at Woolnooth and the Hampshire Hills. They attack the Sheep at night, but are occasionally seen during the daytime, upon which occasions, perhaps from imperfect vision, their pace is very slow. Mr. Gunn also observes that the Thylacinus sometimes attains so large and formidable a size, that a number of Dogs will not face it. That gentleman denies that the tail of the animal is compressed, as has been stated by some authors, and his observations do not confirm the aquatic habits which have been attributed to it. There are cartilages in the place of the marsupial bones; but the pouch is well developed in the female Thylacine, and there are four well developed teats, each four inches long, indicating that it may contain four young ones at a time. The marsupium, or pouch, opens backwards, not, as in the Kangaroos and most others, forwards.
