THE BIRDS OF AUSTRALIA. 
In the Handl. Gen. Spec. Birds, pt. m., p. 106, 1871, Gray included 
under his own F. pJiillipii (which he had proposed for the Norfolk Island 
Petrel of Philhps’s Voyage), specimens collected at Chesterfield Group by 
Macgillivray, and as a doubtful synonym, noted agilis Sol. As this name 
appears in literature, I append Solander’s description : —

The locahty is due south of Easter Island, so the name may be applicable 
to a bird breeding on that Island.
