Fossil remains of this group are found throughout the Miocene of France, Switzerland, Germany, and Italy, referred to _Anser_ and _Anas_, with _Chenornis graculoïdes_; the Pliocene of Oregon has furnished _Branta_, _Cygnus_, and _Anser_, that of Italy _Anas_ and _Fuligula_; the Plistocene of Malta _Cygnus_ and _Palaeocycnus_, that of Brazil _Chenalopex_. The superficial deposits of New Zealand contain _Cnemiornis_, mentioned above, as well as _Chenopis_ and _Biziura_; the Queensland drifts the last-named, and, it is said, _Anas_, _Dendrocycna_, and _Nyroca_; the Mare aux Songes of Mauritius _Anas_ and _Sarcidiornis_. _Centrornis majori_ is a remarkable form {137}from Central Madagascar, found at a depth of twelve to fifteen feet with another species _Chenalopex sirabensis_.[121] ORDER VII. FALCONIFORMES. Next to the aquatic Anseriformes may be placed the large and important terrestrial Order Falconiformes, with its Sub-Orders CATHARTAE and ACCIPITRES. The former contains the New-World Vultures (_Cathartidae_ or _Sarcorhamphidae_), possessing striking differences of structure from their allies;[122] the latter, the Secretary-Bird (_Serpentariidae_), the Old-World Vultures (_Vulturidae_), the Carrion-Hawks, Hawks, Eagles, Falcons and their kin (_Falconidae_), and the Ospreys (_Pandionidae_). All agree in the strong "raptorial" bill with basal cere, the U-shaped furcula, the large crop, the carnivorous habits, the great powers of flight, the superior size of the female, and the long nest-occupation of the young; but the Cathartae differ in having pervious nostrils, no syringeal muscles, less flattened metatarsi, and so forth. Fam. I. CATHARTIDAE.–These Vultures range from tropical to temperate America, and are often of immense size; the bill is strong, hooked, but blunt; the feet are clumsy with small scales; the scutellated toes, of which the mid-digit is longest and the hallux somewhat elevated, are unfit for grasping; the claws are obtuse and little curved. The ample wings have eleven primaries and from twelve to twenty-five secondaries; the moderate tail is even or rounded, with twelve rectrices, or fourteen in _Pseudogryphus_. The head and long neck are commonly bare, but the latter may be covered with stubbly down, which in _Gyparchus papa_ extends to the occiput; the naked skin is often brightly coloured and accompanied by caruncles, while the crop is bare in _Sarcorhamphus_ and _Gyparchus_. The eyes are prominent, the cere is horny and sometimes very long, the tongue thick and fleshy, the aftershaft absent. The sexes are alike in plumage, with evenly distributed down, and the nestlings soon develop a white or rufous covering.
