We find in this species of _Pachycephala_, which inhabits the northern parts of Australia, a beautiful representative of the _P. pectoralis_ of the southern parts of the continent; from which it differs in its much smaller size, and in the black crescent which bounds the white throat of the male not extending upwards to the ear-coverts, which with the lores are grey. All the specimens I possess were killed on the Cobourg Peninsula, near the settlement at Port Essington, where, as well as on the adjacent islands, it is a stationary species, and very abundant. It breeds in September and the two following months, and lays two eggs. Its habits and manners are precisely similar to those of the other members of the family. The adult male has the crown of the head, lores, ear-coverts, back and upper tail-coverts grey; wings dark brown, all the feathers margined with grey; throat white, bounded below by a distinct crescent of black; abdomen, flanks and under tail-coverts orange-brown; tail dark brown, the basal portion of the webs edged with grey; irides reddish brown; bill black; feet blackish brown. The adult female has the crown of the head and all the upper surface grey; ear-coverts brownish grey; throat buffy white, passing into light buff or fawn-colour on the chest, flanks, abdomen and under tail-coverts; the feathers of the throat and chest with a narrow dark line down the centre; wings and tail as in the male. The young male is similar in colour to the female, but has the throat whiter and the markings on the chest much more distinct, and extending over the abdomen also. In very young individuals a rich rufous or tawny tint pervades the greater part of the upper surface. The figures represent the two sexes of the natural size.

Shrike-like Pachycephala. _Pachycephala Lanoïdes_, Gould in Proc. of Zool. Soc., Part VII. p. 142. A single specimen only of this bird has come under my notice, and from the locality in which it was procured, the north-west coast of Australia, it is probable that it is the only one in Europe. On reference to the figure on the Plate, it will be seen that it is a most robust and powerful species, and that it so closely approximates to the form of the genus _Lanius_, that had it been a native of any other country than Australia, where the true Shrikes are not found, it might have been referred to that genus. That it feeds on insects of a large size there can be but little doubt, its whole structure indicating that it exists upon this kind of food. No information whatever has been obtained with respect to its habits and economy; this blank therefore remains to be filled up by those naturalists who may hereafter visit the part of the country of which it is a denizen.
