Phalanger (the "native bear"), the striped marsupial wolf or Thylacine, the Tasmanian Devil, the Marsupial Mole, most of the Dasyures and Bandicoots, are confined in their distribution to Australia and Tasmania, Tasmania being the richest part of Australia in marsupial types. But this region, in common with New Guinea, possesses mammals still more primitive and interesting than the marsupials--the egg-laying sub-class, which contains the two existing forms of Echidna (Porcupine Ant-eater) and Duckbill. The Duckbill, a furry creature the size of a large cat, with the jaws converted into a leathery beak, is only found in the south-east of Australia and in Tasmania. The Echidna and Duckbill do not produce their young alive, but lay eggs from which the young are hatched. Apart from these marsupials and egg-laying mammals, Australia possesses only a few species of the higher mammals: a wild dog, a number of rats--aquatic and terrestrial--and bats; besides, of course, seals on the coasts and rivers, and the strange Dugong.[9] The bats are both of the insect-eating and fruit-eating kinds, and have probably flown over in recent times from New Guinea. From the same direction likewise have travelled the Australian rats, some of which have taken to a water life. As to the Dingo or Wild Dog, that may have been introduced by the early human inhabitants who came to Australia from Malaysia, but it has inhabited Australia for a very long period, though it did not reach Tasmania. It is related to a wild dog of Java. There is said to be a wild dingo in New Guinea. [9] The Dugong, very commonly met with in the early stories of Australasian adventure, is an aquatic mammal, the size of a large porpoise, which belongs to the order of the Sirenians. It frequents the shores of estuaries and seacoasts with plenty of seaweed. It is a vegetable feeder only. See p. 165. Australian birds are very noteworthy. In the extreme north there is the Cassowary, which elsewhere is only found in New Guinea, the Bismarck Archipelago, and the Island of Ceram. Nearly the whole of Australia, however, was at one time frequented by the Emu, a large, flightless bird only second in size to the Ostrich. The Emu once extended its range to Tasmania as well as to Kangaroo Island, off the south coast of the continent. The Parrot order is more abundantly represented in Australia than anywhere else. In New Zealand and the tiny Norfolk Island there are species of a remarkable type of Parrot--the Nestor--which has a very long beak, not deep, like that of other parrots. The family of brush-tongued Lories is represented in the island continent by many beautiful forms. Here also developed originally the Cockatoos, which have since spread to New Guinea and the eastern Malay islands. The True Parrots and Parrakeets are well represented in New Guinea and Australia, and assume in some cases the most lovely and delicate coloration. [Illustration: THE BIGGEST OF THE KANGAROOS
