casuariidæ

Century Dictionary and Cyclopedia

1. A family of struthious birds, of the order or subclass Ratitæ, having three toes, the wings rudimentary, and the aftershafts of the feathers highly developed. It is confined to the Australian and Papuan regions, and is divided into the Casuariinæ and the Dromæinæ, two subfamilies which contain the cassowaries and the emus respectively. See cuts under cassowary and emu.
2. The Casuariinæ alone, elevated to the rank of a family, the emus in this case being separated as another family, Dromæidæ.
