PETROICA SUPERCILIOSA, _Gould_. White-eyebrowed Robin. _Petroica superciliosa_, Gould in Proc. of Zool. Soc., Part XIV. p. 106. For our knowledge of this new species of _Petroica_ we are indebted to the researches of Mr. Gilbert, who while in company with Dr. Leichardt, during his adventurous expedition from Moreton Bay to Port Essington, discovered it in the neighbourhood of the Burdekin Lakes towards the Gulf of Carpentaria. The following remarks in Mr. Gilbert’s Journal comprise all that is at present known respecting it:—“May 14th. In a ramble with my gun I shot a new bird, the actions of which assimilate to those of the _Petroicæ_ and the _Eöpsaltriæ_; like the former it carries its tail very erect, but is more retiring in its habits than those birds; on the other hand, its notes resemble those of the latter. It inhabits the dense jungle-like vegetation growing beneath the shade of the fig-trees on the banks of the Burdekin. I succeeded in procuring two specimens.” Superciliary stripe, throat, abdomen, under surface of the shoulder, and the bases of the primaries and secondaries white; lores, ear-coverts, wing-coverts, and the primaries and secondaries for some distance beyond the white deep black; all the upper surface, wings and tail sooty brown; all but the two central tail-feathers largely tipped with white; bill and feet black; irides reddish brown. The Plate represents the two sexes of the natural size. [Illustration: DRYMODES BRUNNEOPYGIA: _Gould_ _J. Gould and H. C. Richter del et lith._ _C. Hullmandel Imp._ ] DRYMODES BRUNNEOPYGIA, _Gould_. Scrub Robin. _Drymodes brunneopygia_, Gould in Proc. of Zool. Soc., Part VIII. p. 170. I discovered this singular bird in the great Murray Scrub in South Australia, where it was tolerably abundant; I have never seen it from any other part of the country, and it is doubtless confined to such portions of Australia as are clothed with a similar character of vegetation. It is a quiet and inactive species, resorting much to the ground, over which and among the underwood and low stunted bushes it passes with great ease; it appeared rarely to take wing, but to depend for security upon its dexterity in hopping away under the dense underwood of the most scrubby parts; I have, however, occasionally observed it to mount to the most elevated part of a low bush, and there pour forth a sharp monotonous whistling note, not very unlike that of some of the _Pachycephalinæ_; indeed it was its note that first attracted my attention and led to its discovery. When on the ground, and sometimes when perched on a twig, it elevates its tail considerably, but not to the extent of the _Maluri_. This new form evidently belongs to the _Saxicolinæ_, and has many habits in common with the members of the genus _Petroica_.
