Pedes, fortes: tarsis subelongatis, in fronte scutellatis; digitis unguibusque elongatis, hic fortioribus subcompressis; halluce fortissimo, incumbente.
This genus appears to have some resemblance to MM. Quoy and Gaimard's genus Megapodius: but no specimen of it being in this country, and my bird differing in essential points from its generic characters, particularly in the length and form of the wings, which in my bird are rounded, and so short as not to reach beyond the base of the tail, I have formed it into a new genus, for which the term Hylactes (from its note, which very much resembles the sharp bark of a dog) has been selected.

The specific name I have selected is in compliment to Mr. John Tarn, surgeon of the Adventure, to whose attention, in procuring and preserving numerous specimens in ornithology, I am greatly indebted.
33. Struthio Rhea.—Lin. (223.)
The American ostrich. Maldonado.
34. Columba Fitz Royii.—Nob. in Proceedings of Zool. Soc.
