Platycercus unicolor, Vigors. (Antipodes Island Parrakeet.)

I take this opportunity of exhibiting an egg of this species which was laid by a captive bird on board the "Hinemoa" on her last voyage from the islands. As will be seen, it is perfectly white, with a smooth surface, and almost spherical in shape, measuring 1in. in length by 0.9in. in extreme width.
