FIRST EDITION, published some twenty years after Gould's folio work on the birds of Australia was completed. "During that period many new species have been discovered, and much additional information acquired respecting those comprised therein; consequently it appeared to me that a careful resume of the entire subject would be acceptable to the possessors of the former edition" (Preface, p.vii).
