HALMATURUS GREYJ, Gray. Grey’s Wallaby. Urrer Haur or a Mate anno Heap or a FEMALE, OF LIFE-SIZE. Tuer name of Sir George Grey must always be conspicuous in the annals of Australian history, whether we regard this enlightened and valuable public servant as an explorer or a ruler; and, for my own part, I am much gratified that so fine a species as the present should have been named in honour of the present Governor of New Zealand. The Halmaturus Greyi, if not so beautiful as the H. manicatus, is very little inferior in = = this respect to that species. It will be seen that, while the forearm is as short as in that animal, the black colourmg of the fore feet is not so sharply defined, and that on the tips of the ears this colour is wholly or nearly absent. South Australia is the native habitat of this fine animal; it therefore inhabits that part of the country lying between the eastern and western parts of the continent. Those who are not well versed in the Mammals of Australia may perhaps consider the variation in the shades of colour above mentioned insufficient to constitute a species; but I can assure them that such is not the case. The H. Greyi is further distinguished from both the H. ruficolhs and H. manicatus by having a more-lengthened-hairy or shaggy coat, by its nearly white tail, and generally lighter colouring.
