Crown of the head, ear-coverts, and all the upper surface olive-brown; throat white; chest and all the under surface bright citron-yellow; two centre tail-feathers brown, the remainder brown at the base, above which is a bar of white, succeeded by a broader one of deep blackish brown; the tips of all but the two middle ones buffy white on their inner web; bill blackish brown; irides scarlet; feet blackish brown in some specimens, and leaden brown in others. The figures represent an adult and a young bird of the year of the natural size. [Illustration: GERYGONE FUSCA: _Gould_. _J. Gould and H. C. Richter del et lith._ _Hullmandel & Walton Imp._ ] GERYGONE FUSCA, _Gould_. Fuscous Gerygone. _Psilopus fuscus_, Gould in Proc. of Zool. Soc., Part V. p. 147; and in Syn. Birds of Australia, Part IV. _Gerygone fusca_, Gould in De Strzelecki’s Phys. Descr. of New South Wales and Van Diemen’s Land, p. 321. The _Gerygone fusca_ is an inhabitant of New South Wales, where it is to be found in all the brushes near the coast, as well as in the cedar and other brushes on the sides of the ranges in the interior. As its form would lead us to imagine, it has much of the habit of the Flycatcher, and lives almost exclusively upon insects, such as aphides and other swift-winged species, which are as frequently taken on the wing as they are on the under sides of leaves, &c. It particularly loves to dwell in the most retired and gloomy part of the forest, among the creeping Bignonias, &c., and is a most active and lively little bird, flitting about from branch to branch; sometimes, like the true Flycatchers, returning again to the same branch, and at others hanging to the smaller branches and scrutinizing the under sides of the leaves, after the manner of the _Acanthizæ_. Its song, which is almost incessantly poured forth, is a pleasing, twittering sound. The breeding-season comprises the months of September, October and November. The nest is a delicate and beautiful structure of a domed oblong form, the lower end terminating in a point, with the entrance at the side near the top covered with a well-formed spout, which completely excludes both sun and rain from the interior of the nest; it is about eight inches in height and ten in circumference; the spout projecting about two inches, and the entrance being scarcely an inch in diameter. The body of a nest found in the brushes of the Hunter was composed of green moss, mouse-eared lichen, soft wiry grasses, the inner bark of trees and other materials, and was lined with extremely soft grasses. The eggs are three in number, and are very similar, both in size and colour, to those of the _Malurus cyaneus_, being minutely speckled with red on a white ground; they are seven and a half lines long by five and a half lines broad. The sexes are alike in colour.
