Zanthopygia
(syn. Ficedula Ϯ Yellow-rumped Flycatcher F. zanthopygia) Specific name Muscicapa zanthopygia Hay, 1845; "Zanthopygia, nobis.  This is a genus of Chat-flycatchers, which I am not as yet prepared to approximate to any other. In the form of its beak, it bears much resemblance to the Australian genera Eopsaltria and Petroica (which branch off from Pachycephala*), and also to the Pratincolæ; but of the two species to be described, the bill of the first is vertically deeper than that of the second, which renders generalization more difficult, although the generic identity of the two birds is unquestionable.  Bill of mean length, acutely triangular as viewed from above, or much narrower than in the more characteristic Flycatchers; its upper ridge angulated, and the tip of the upper mandible incurved and emarginated: gape beset with fine hair-like vibrissæ.  Tarsi and toes moderately small and weak, the tarse as long as the middle toe with its claw; wings reaching half-way down the tail, their first primary short, only a quarter the length of the second, which is shorter than the fifth, the third and fourth being subequal and longest.  Tail of mean length.  Plumage rather firm: the males black above, with yellow rump and under-parts, and a large white wing-spot.  From Malasia.    Z. leucophrys, nobis.   ...   Colour deep black above, bright yellow below and on the rump   ...   The female^Ϯ differs widely in being a light olive-green above, tinged with grey  ...  From Malacca.    Z. chrysophrys, nobis.  ...  The female I have not seen, nor am I aware of the habitat of the species; but have some reason to suspect Australia, in which case it will probably bear a prior name.   ...    *Timixos meruloides, nobis, J.A.S. XI, 195, is Pachycephala olivacea, Vig. and Horsf.    ^ϮMuscicapa zanthopygia, A. Hay, Madr. Journ. No. XXXI [= XIII], 162." (Blyth 1847); "Zanthopygia Blyth, 1847, Journ. Asiat. Soc. Bengal, 16, p. 123; emended to Xanthopygia by G. R. Gray, 1855, Cat. Gen. Subgen. Birds Brit. Mus., p. 53. Type, by subsequent designation (G. R. Gray, 1855, p. 53), Zanthopygia leucophrys Blyth [= Muscicapa zanthopygia Hay, 1845]." (Watson in Peters 1986, XI, 335).    Var. Xanthopygia.
