PETROGALE INORNATA, Gowa. Unadorned Rock-Wallaby. Upper Haur or tHe ANIMAL, OF THE SIZE OF LIFE. Tue northern as well as the southern portions of the Australian continent are evidently tenanted by members of that section of the Kangaroos to which the present species belongs; for although a single example only has yet reached me from the north coast, it is sufficient to show that such is the case. The P. inornata is a true Petrogale, and, like the P. concinna, merely differs from its congeners in the total absence of stripes or markings on its sides. This plain-coloured but rare species is one I would recommend to the notice of the naturalists and explorers who may visit the north coast of Australia, where it was dis- covered by Mr. Bynoe. reduced figure of the entire animal will be found on the next Plate.
