With the exception of its being even more shy, its whole habits and economy appeared to be very similar to those of the preceding species (_H. pyrrhopygia_). It carries its tail perfectly erect, and hops over the ground and threads the bushes with the greatest alacrity; generally keeping among the more dense parts of the low bushes, and only exposing itself on the outermost twigs when desirous of pouring forth its song, which is sweet and harmonious, and by which its presence is more frequently detected than by any other means. I could neither find the nest and eggs myself nor obtain any information respecting them; but I have no doubt that when discovered the nest will be found to be of a domed form, with a small hole for an entrance, and the eggs very similar to those of the _Maluri_. In size the _H. cauta_ is rather less than the _H. pyrrhopygia_, has the markings of the under surface much bolder, and the chestnut-coloured mark on the rump of a much deeper tint. Line from the base of the upper mandible along the side of the face and over the eye white; above this a narrow line of black; crown of the head and all the upper surface brown; upper and under tail-coverts bright chestnut; wing-coverts brown, edged with brownish white; primaries brown, with the outer web white at the base, forming a conspicuous spot in the centre of the wing; tail blackish brown, tipped with white; throat striated with black and white, produced by each feather being black down the centre and fringed with white; flanks mottled brown and white; abdomen white; hill dark brown; irides buffy white; feet flesh-brown. The figures are of the natural size. [Illustration: CYSTICOLA MAGNA: _Gould_. _J. Gould and H. C. Richter del et lith._ _Hullmandel & Walton Imp._ ] CYSTICOLA MAGNA, _Gould_. _Cysticola campestris_, Gould in Proc. of Zool. Soc., Part XIII. p. 20. I am indebted to the kindness of Hugh E. Strickland, Esq., for the loan of a fine example of this bird for the purpose of figuring in the present work. It is one of the largest species of the group, and hence I have assigned to it the distinctive appellation of _magna_. Nothing whatever is known of its habits and manners, but we may reasonably infer that they are very similar to those of its congeners. The precise locality it inhabits is also unknown; Mr. Strickland having obtained it from a general collection of Australian birds, without the situation in which it had been procured being attached to it. Head rusty red; back and wing-coverts brownish grey; all the feathers of the upper surface with a broad stripe of dark brown down the centre; wings blackish brown, the primaries margined externally with rusty red and the secondaries edged all round with brownish grey; tail reddish brown, all but the two centre feathers with a large spot of black near the tip; all the under surface pale buff. The Plate represents the bird of the natural size. [Illustration:
