The Pliocene and Quaternary flamingoes of Australia.

From the Quaternary deposits of NE S Australia, material of what appears to be 4 species of flamingo has been recovered. These in order of size are referred to: Xenorhynchopsis tibialis de Vis, 1905, Phoenicopterus ruber Linnaeus, 1758; Xenorhynchopsis minor de Vis, 1905; and Ocyplanus proeses de Vis, 1905. De Vis was unaware that some of the bones he named were those of flamingoes and assigned them a follows: Xenorhynchopsis tibialis and X. minor to the Ciconiidae, storks; Ocyplanus proeses to the Charadrii, waders; and Ibis (?) conditus to the Threskiornithidae, ibises. Miller was unaware that de Vis had named and incorrectly assigned some flamingo material. Ocyplanus proeses was reassigned by Lambrecht to the Laridae, gulls, and by Condon to the Rallidae, rails, both identifications which are also incorrect. The material consists of bone fragments, most of which are not diagnostic at the generic level. We have provisionally retained the generic and specific names that have priority as a convenience until more complete material allows a better evaluation of the systematic positions of the Pliocene and Quaternary flamingoes of Australia.-from Authors
