The whole of the plumage buffy white, with the exception of the primaries, secondaries and greater wing-coverts, which are greyish black, and the tips of the tail-feathers, which are black, the black becoming of less extent as the feathers recede from the centre of the tail, until the outer feather is only slightly tipped; this feather is also broadly margined with black on the outer web for three-fourths of its length from the base; the under tail-coverts also have an irregular band of black near the tip of each feather; irides dark brown; bill dark greenish grey, except the tip, which is light yellow. The figure is of the natural size. [Illustration: LOPHOLAIMUS ANTARCTICUS: _G. R. Gray_. _J. & E. Gould del et lith._ _C. Hullmandel Imp._ ] LOPHOLAIMUS ANTARCTICUS, _G. R. Gray_.

Appendix to 2nd Edit., p. 12. Top-knot Pigeon of the Colonists of New South Wales. Although the specific term of _antarcticus_ is not an appropriate appellation for this noble Pigeon, still it cannot, I think, with strict propriety be sunk into a synonym, since it was first applied to it in a work intended exclusively to illustrate the zoology of New Holland, as will be seen on reference to the synonyms above quoted. I feel assured that my excellent and scientific friend M. Temminck was either unacquainted with the publication alluded to, or that the circumstance of its having been previously described and figured had escaped his memory, when he characterized this bird in the thirteenth volume of the “Linnean Transactions,” and subsequently figured it in his “Planches Coloriées,” under the name of _Columba dilopha_.
