Mr. Gould, who is now engaged in a work upon the Ornithology of Australia, having been solicited to furnish a list of the Birds of the Western coast, has kindly forwarded the following enumeration of the species which have come under his notice as inhabiting that part of the country. The list, although necessarily incomplete, is the most perfect that has yet been published, and will doubtless be of considerable interest to the scientific as well as the general reader.
