a British island in the South Pacific Ocean, in 54 0 49' S. and 1 59° 49' E. It is about 20 M. long, and covered with a grassy vegetation, with some trees or shrubs in the sheltered places which afford food to a parrot of the genus Cyanorhamphus, allied to those of the Auckland Islands. Although it has no settled population, Macquarie is constantly visited by sailors in quest of the seals which abound in its waters.
