​KERMADEC, a small group of hilly islands in the Pacific, about 30° S., 178° W., named from D’Entrecasteaux’s captain, Huon Kermadec, in 1791. They are British possessions. The largest of the group is Raoul or Sunday Island, 20 m. in circumference, 1600 ft. high, and thickly wooded. The flora and fauna belong for the most part to those of New Zealand, on which colony the islands are also politically dependent, having been annexed in 1887.
