HALMATURUS RUFICOLLIS. Rufous-necked Wallaby. Heap AnD ARMS OF BOTH SEXES, OF THE SIZE OF LIFE. AN opinion exists among zoologists that the Halmaturus Bennetti, which is exclusively confined to Tasmania, and the H. rujicollis of the opposite portion of the Australian con- tinent, are one and the same species, and that the difference in the colouring of the two animals is merely the effect of climate; the full-sized heads, then, which are given as accessories to the reduced figures on the succeeding Plate will be of value as illustrative of the difference in question. Certain it is, that all the specimens from the continent (the H. ruficollis of this work and of previous authors) are much redder in colour, and have the white of the cheeks extending further on the breast, than the H. Bennetti procured in Tasmania. As these differences are carefully detailed on the succeeding page, it will not be necessary to enter into them here. The accompanying Illustration represents the head and forearms of both sexes, as near the size of life as possible. a a SE a eee aera nan one
