_Asarcornis scutulata_, ranging from East Bengal to Java, has a black and white head, black mantle and under surface, greenish-olive upper parts, with black and white on the wings, a blue-grey speculum, reddish bill and feet. _Sarcidiornis melanonota_, of India, Ceylon, Burma, and the Ethiopian Region, is black with metallic hues above, and white below; the head and neck are black and white, the rump is grey, the tail brown, the feet, bill, and its basal comb or caruncle black. _S. carunculata_, of Brazil, Paraguay, and North Argentina, differs in its black rump. The comb is largest in the breeding season, and is wanting in females. These Wattle-Ducks perch on trees and breed in cavities of the trunks, laying a dozen or more white eggs. The note is harsh and the flight slow. _Cairina moschata_, the Muscovy–or more correctly Musk–Duck of ornamental waters, extends from Mexico to Argentina; the crested head, neck, and lower parts are brownish-black; the upper surface is glossy green, with purple on the back and white wing-coverts; the bill is black and white; the feet are black; and the frontal and orbital caruncles of the male red. It inhabits forest-swamps, roosts in trees, eats maize, mandioc roots, and herbage, and nests in holes in trees or between forking branches. _Plectropterus gambensis_ of Mid-Africa, _P. rüppelli_ of the North-East, _P. niger_ of the South-East, and _P. scioanus_ of Shoa, the four hardly separable Spur-winged Geese, are metallic black, with more or less white on the sides of the head, lesser wing-coverts, throat, and abdomen; the feet, bill, frontal knob, {135}and caruncles on the forehead when present being red. The female has no knob. They frequent marshes, appear to prefer running to flying or perching, and lay about eight whitish eggs. Sub-fam. 10. _Anseranatinae._–This contains only _Anseranas semipalmata_ of Australia and Tasmania, a white bird with black head, neck, mantle, wings, and tail, reddish beak, and yellow feet. It haunts swamps, walks easily, and deposits some five white eggs. Sub-fam. 11. _Cygninae._–In this group the sexes are similar. _Coscoroba candida_, of southern South America, is white, with black tips to the primaries, pinkish bill and feet. It feeds on land, has a loud trumpeting cry, and a less noisy flight than the true Swans, from which it differs in its feathered lores. _Chenopis atrata_, the Black Swan of Southern Australia and Tasmania, occasionally domesticated in England, is brownish-black, with white remiges, black feet, pink lores, and pink bill banded with white, the scapulars and inner secondaries being curled.
