Tus singular bird—which is referred to the genus Cinclosoma, a genus differing from the Thrushes, Shrikes, and Crows, to each of which it offers certain points of analogy—is a species of the greatest rarity; neither descriptions, drawings nor specimens, having come under our notice previously to the one in the present collection ; and even now, a solitary example is, we believe, all that our museums can boast of. The loose flowing feathers of its back, together with its short rounded wings and graduated and lengthened tarsus, ally it in a very marked manner to the Bush Shrikes of South America: our opinion, however, wants that confirmation which a knowledge of its habits and manners alone can impart. The specimen alluded to was received from the mountains, to the remote part of which we have every reason to believe it is exclu- sively confined. The head is slightly crested with blackish brown feathers; the cheeks, wings, the whole of the upper surface, and the two middle tail-feathers, are rufous brown; each feather on the back being tipped with white, those on the upper parts having a black band above the white spot; the throat is blackish brown; the breast pale rufous, banded with black ; the whole of the under parts uniform pale brown; the quill- and outer tail- feathers are dark silvery grey tipped with white; the beak and feet brown. The figure is of the natural size.
