Hob. St. Paul's and Amsterdam Islands (breeding) ; Kerguelen -, 

 Tristan da Cunha and Inaccessible Islands, and the Atlantic to the 

 vicinity of Brazil. M. Velain describes this species as depositing 

 its egg in the most inaccessible places in the crater at St. Paul's 

 Island. There can be no doubt that Latham's locality " Christmas 

 Island " (where no Tern except S. fuliginosa was found on Cook's 

 voyage) was a mistake for Christmas Harbour, Kerguelen Island, 

 where Cook landed.
