In conclusion, there are two factors that may be the cause of this variation in G. f/77iVr», cross-breeding with G. Icnconota. and variation under nature. The writer's opinion is that it is purely a natural variation, whereby in one locality the typical birds when mated ])erpetuate a greater percentage of their ])rogeny true to type ; whilst in other localities, these variations are in evidence, and that a "zvJiitc-backed" bird seen associated with a "black-backetl" or partial '"black-backed" bird may be purely a variation of G. iibiccii, as in Fig. E, anil not a (/'. leuconota species, as in Fig. F.

Remarks and Notes on some Western Australian Birds

By TOM CARTER, R.A.O.U., Sutton, England.

On page 123 in The Emu, vol. xx., Part 3 (January, 1921)^ Mr. Ashby states that the Bristle-Bird (Sphenura littoralis) was locally known at Ellensbrook as the "Rain-bird." It was the Coachwhip Bird (Psophodes nigrogularis) that was so called, as stated by Mr. Milligan in his paper, The Emu, vol. ii., p. 72. When I was staying at Ellensbrook in November, 1902 (vide The Emu, vol. iii., p. 38-K)), Miss Bussell referred to the Black-throated Coachwhip-Bird, in conversation with me as the Rain-bird, and said how much she missed hearing certain notes uttered by this bird, that invariably foretold rain. Page 123-24, Mr. Ashby expresses surprise at finding that Mallee Fowl {Leipoa ocellata) breeds at Cape Naturaliste, and surmises that birds from that locality may prove to be a good sub-species. Mr. G. M. Mathews classes the Western Australian Leipoas as one species. These interesting birds have been well known (locally) to breed all along that coast, and past the Cape Leeuwin, to at
