That this fine species enjoys a wide range over the southern 

 ocean is certain, the specimen figured by Vieillot in his 'Galerie 

 des Oiseaux ' having been procured at New Zealand, while 

 numerous individuals in my own collection were procured in 

 Australia. Gilbert discovered it breeding on some of the 

 small islands lying off Cape Leuwin in December, where he 

 procured numbers of its eggs, as well as many examples of 

 the adult birds ; he also met with it on a small island about 

 three miles south of East Wallaby Island in January, by 

 which time the young birds were almost ready to leave their 

 holes. The specimens procured on this island are peculiarly 

 interesting, as showing how completely the true feathers are 

 assumed before the downy covering is thrown off. 



The egg of this species is pure white, one inch and a half 

 long by one inch and an eighth broad : whether one or two 

 are laid at a time is uncertain, but I believe only one. 



Eorehead, face, line over the eye, and all the under surface 

 pure white ; crown and nape, a broad patch beneath tile eye.
