Warroon of the Aborigines of the Illawarra district. r Paris and Leyden; the specimens therein contained have been described under at least two specific names, 7w/icollis and i) Tuts species of Haimaturus has been long known as forming part of the continental collections, particularly those « rufo-griseus, and Mr. J. E. Gray believes that the Macropus elegans of Lambert is also referable to the same animal ; an opinion in which, however, I cannot concur, as neither the drawing in the ‘ Linnean Transactions,’ nor the accompanying description of the fur, which is said to be of “a beautiful silver-grey,” at all agrees with the one here figured, in any state of its colouring. The J. elegans is, moreover, said to be very scarce in New South Wales, while the . ruficollis is more abundant there than any other: the aboriginal name of the latter is Warroon, while that of the former is said to be Ba-garee; a further argument in favour of their being distinct. The undefined markings and variable colouring of the present animal have much puzzled me, and I am led to suspect that the Brush Wallaby of Van Diemen’s Land, to which Mr. Waterhouse has given the name of Bennetéz, in honour of the late estimable Secretary of the Zoological Society, may be identical with it; and I am strengthened in this suppo- sition, by having observed that, as we proceed from Van Diemen’s Land northward through the islands of Bass’s Straits to the continent of Australia, the thick dark-coloured fur gradually gives place to a thinner and rusty red coat similar to the figures here given, from examples taken in New South Wales; but should this supposition ultimately prove to be unfounded, it must be conceded that the larger species of Wallaby inhabiting Flinders and King’s Islands will be refer- able to the present species, and not to Bennettii, whose habitat would then be confined to Van Diemen’s Land. I may here mention, that Peron’s specimens in the Paris Museum were collected on King’s Island, and are the originals from which Desmarest took his descriptions of ruficollis and rufo-griseus. I hope ere long to receive perfect skeletons of this or these animals, as the case may be, from different localities, by which means alone can it be determined whether or not they are identical. This species was formerly common near Sydney, but is now gradually retiring before the advance of civilized man ; it is still, however, abundant in the thick Daveysza scrub on the table-land behind Illawarra, particularly on the fine estate at Bong-Bong, belonging to Charles Throsby, Esq., to whom I am indebted for many friendly attentions, and for his assistance in procuring fine specimens of this animal.
