Feejee Islands, South Pacific. The above description is taken from a female specimen from Kandavu, Feejee Islands, taken on the nest on the 10th of September, 1876, and sent over by Mr. Theodor Kleinschmidt to the Museum Godeffroy. The large size, the deeply forked tail, and the singular coloration distinguish this species at once from any other member of this group. |
