I. Introduction. 



On his zoological expedition to Central America the 

 late Docent at the R. University of Upsala, Doctor Carl 

 BovALLius, for nearly two months (March and April 1882) 

 visited the Pearl Islands in the Bay of Panama, gathering to- 

 gether in various parts of the archipelago a collection of great 

 interest. The birds of this collection are now for the main 

 part kept in the State Museum of Natural History in Stock- 

 holm, but some of them belong to the Zoological Museum of 

 the R. University of Upsala. 



I have had the pleasant task to determine and classify 

 these birds, and in the following I have combined the results 

 thereof with the facts already known about the birds of these 

 islands so as to give a complete account of their bird-fauna 

 to the public. 



Before the year 1900, we can say, that these islands were 

 from an ornithological point of view nearly unexplored, there 

 being only some species in the collections of the British Mu- 

 seum (coll. Kellett and Wood. Cat. Birds Brit. Mus.) and 

 two species in the State Museum in Stockholm (Eugenie's 

 Expedition. Unpublished. ) 



In the year 1900 Mr. W. W. Brown at the request of the 

 brothers Bångs visited the San Miguel Island, the largest
