Generic characters.
As in Platycercus, but the bill more feeble; cere and nostrils covered with fine hair-like feathers; wings longer and less concave; tail more square; tarsi shorter and toes longer than in that genus.
Two, if not three species of this form inhabit Australia, and others are found in New Guinea and the neighbouring islands. They are distinguished from the Platycerci by the possession of a well-developed os furcatorium, a bone which is entirely wanting in the members of that genus; in their habits they are mainly arboreal, and in their disposition are morose and sullen.
