These birds resemble cassowaries, but belong to a different genus and subfamily, and are easily distinguished by having no casque or helmet on the head, which, with the neck, is more completely feathered. The plumage is sooty-brown or blackish, and very copious, like long curly hair, there being two plumes to the quills, so that each feather seems double. The wings are rudimentary, useless for flight, and concealed in the plumage. The emus are intermediate in size between the cassowaries and the ostriches. The species first named above is the one most commonly seen in confinement.
