Excerpt from Proceedings of the Royal Society of Victoria, 1901, Vol. 14: Part I; Edited Under the Authority of the Council; Issued August, 1901 (Containing Papers Read Before the Society During the Months of May and June, 1901) The warrant for the acceptance of the species of this genus appears to be as follows - The white-backed species is different from the black-backed species in the region of the back. The Lesser white-backed species is said to be smaller than the white backed. The long-billed species is said to have a longer and slenderer bill than any other of this genus. Thus, briefly, we have the leading characters of the four species of this Australian genus. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
