How wonderfully are all these forms adapted to a separate and C ’ = special end and purpose—an end and a purpose which cannot be seen to Se in any but a compara- tively undisturbed country like Australia—a part of the world’s surface still in maiden dress, but the charms of which will ere long be ruffled and their true character no longer seen! Those charms will not long survive the intrusion of the stockholder, the farmer, and the miner, each vying with the other to obliterate that which is so pleasing to every naturalist ; and fortunate do I consider the circumstances which induced me to visit the country while so much of it remained in its primitive state. I must revert to the Kangaroos; for it will be necessary to point out the situations affected by the various genera. In the body of the work three species of true MZacropi are figured, and others are described, but not represented. ‘These are all inhabitants of the southern districts of Australia and Van Diemen’s Land. To say that no true Macropus, as the genus is now restricted, will be found in Northern Australia would be somewhat unwarrantable; at the same time, I have never seen an example from thence. The oenus 3 J § PS Osphranter, on the other hand, the members of which, as has been before stated, are always found in rocky IX & situations, have their representatives in the north as well as in the south, but they are not found in Van i Diemen’s Land, The splendid O. vufus is an animal of the interior, and frequents the plains more than any K other species of its genus. At present, the back settlements of New South Wales, Queensland, Victoria, JN. and South Australia are the only countries whence I have seen specimens. The Great Black Wallaroo (0. OK robustus) forms its numerous runs among the rocks, and on the summits of mountains bordering the rivers J Mokai and Gwydyr. The O. Parryt ranges over the rocky districts of the headwaters of the Clarence and R adjacent rivers, while the O. antilopinus is as yet only known in the Cobourg Peninsula. UE The smaller Petrogale differ from all the other Kangaroos, both in the form of their feet and the structure of their brushy dangling tails.
