7. Notes on the Birds of the Navigators' and Friendly 

 Islands, with some Additions to the Ornithology of Fiji.

at New Caledonia. 



[Received May 24, 1876.] 



Recent visits to the Navigators' and Friendly archipelagos having 

 enabled me to extend my knowledge of the avifauna of these two 

 groups of islands, so intimately connected with the ornithology of 

 Fiji, I offer the accompanying remarks for publication in the Pro-
