Fossil remains are recorded from the Pacific, Australia, and New Zealand, which are referred to the genera _Puffinus_, _Ossifraga_, and _Diomedea_, and probably belong to existing species; _Puffinus conradii_ is from the American Miocene, _P. cyermani_ from Tavolara, off Sardinia; but a much more remarkable fact is the discovery in the Suffolk Red Crag of portions of a distinct form, named _Diomedea anglica_ by Mr. Lydekker.[72] {70}CHAPTER IV NEORNITHES CARINATAE _CONTINUED_ BRIGADE I–LEGION II (PELARGOMORPHAE). ORDERS: CICONIIFORMES–ANSERIFORMES– FALCONIFORMES ORDER V. CICONIIFORMES. The Order Ciconiiformes is a somewhat unwieldy assemblage consisting mainly of Water-birds, which may be classed under the Sub-Orders STEGANOPODES, ARDEAE, CICONIAE, and PHOENICOPTERI. Of these the first contains the _Phaëthontidae_ or Tropic-birds, the _Sulidae_ or Gannets, the _Phalacrocoracidae_ or Cormorants and Darters, the _Fregatidae_ or Frigate-birds, and the _Pelecanidae_ or Pelicans; the second the _Ardeidae_ or Herons and Bitterns, and the _Scopidae_ with the Umbrette; the third the _Ciconiidae_ or Storks and Wood-Ibises, and the _Ibididae_ or true Ibises and Spoon-bills; while the fourth comprises the _Phaenicopteridae_ or Flamingos, and the extinct genus _Palaelodus_, for which Dr. Gadow recognises a separate family _Palaelodidae_. Among these the greatest affinity to the _Procellariiformes_ is exhibited by the _Steganopodes_, whereas the _Phoenicopteri_ are so closely allied to the _Anseriformes_ that not a few writers prefer to include them in that Order. The STEGANOPODES are aquatic and chiefly marine birds, so far homogeneous in structure that the details may well be set forth in common; while in some points they bear a great resemblance to the _Cathartidae_.[73] Each Family contains a single genus, except the _Phalacrocoracidae_, where _Phalacrocorax_ and _Plotus_ may be considered the equivalents of Sub-families.
