Intended by the author to serve as "a kind of handbook" to his folio work The birds of Australia, published in 1848. See Introduction, v.1, page 6, and Preface, v. 1, page v: "During that period [since publication of The birds of Australia] many new species have been discovered, and much additional information acquired respecting those comprised therein; consequently it appeared to me that a careful résumé of the entire subject would be acceptable to the possessors of the former edition, as well as to the many persons in Australia who are now turning their attention to the ornithology of the country in which they are resident."
