_Metopiana peposaca_, of South America, northward to Chili and South Brazil, is black with grey vermiculations above and on the belly, the cheeks and upper neck are purplish, the speculum and inner primaries chiefly white, the bill and its swollen base carmine, the feet yellow. The female is brown, with whitish under parts and grey on the wing. It frequents marshes on the Pampas, has a rapid heavy flight, utters a long hoarse note, and lays a dozen creamy eggs. _Netta rufina_, the Red-crested Duck, found from the Mediterranean to the Caspian and Turkestan, or to India in winter, rarely occurs in Britain or North Europe, and is recorded once from America; it is chiefly greyish-brown above and blacker below, with a large crest on the chestnut head, white speculum and sides, red beak and feet. The crestless female is duller, with whitish cheeks and throat. Sub-fam. 5. _Anatinae_ or typical Ducks.–_Heteronetta atricapilla_, of South Brazil, Uruguay, Chili, and Argentina, is dark brown above with black head and rufous vermiculations, and white below with dusky markings; the tips of most of the wing-feathers are white, the bill is blackish with basi-lateral flesh-coloured spots, the feet are brownish. The female's head is brown. _Stictonetta naevosa_, of West and South Australia and Tasmania, is brown with freckles and spots of white in either sex. _Marmaronetta angustirostris_, ranging from South Europe and North Africa to India, and {124}occurring in the Canaries, is greyish above, with brown and buff marblings, and whitish below with brown bars. It flies low, utters a croaking whistle, and lays ten or eleven buff eggs in isolated tussocks. Both sexes of _Malacorhynchus membranaceus_, the Pink-eyed Duck of Australia and Tasmania (p. 111), are grey-brown with lighter dots, and some white on the face, wing, and tail; the under parts are whiter with brown bands, while behind each blackish eye-patch is a pink mark, situated below a dark line running to the occiput and down the nape. The bill is greenish, and the feet are emerald-coloured or yellowish. This species is a fearless denizen of still waters, with a habit of laying its six rich buff eggs in old Herons' nests, in holes in trees, or on flat branches.
