The land birds of Cocos Island, Costa Rica, and of the 
Galapagos Islands are treated in the present connection, with 
the exception of the Galapagos Dove already considered in 
the earlier paper. The sequence and nomenclature of species 
in both papers is that of Sharpe’s “Hand-list of the Genera 
and Species of Birds.” 
As the species of the genera Geospiza and Camarhynchius 
demand a thorough revision with all available material at 
hand, the writer uses provisionally, with a few changes, the 
specific names as defined by Messrs. Rothschild and Hartert? 
and Messrs. Snodgrass and Heller. Wherever the writer 
fails to recognize a species admitted by these authors, the re- 
jected name is placed in a selected synonymy. 
The localities listed for each species also include those 
mentioned by Messrs. Salvin,* Ridgway,? Rothschild and 
Hartert, and Snodgrass and Heller. 
For a full description of the botanical regions or zones (dry 
or arid, moist or humid, and grassy, in order from seashore 
to mountain top) mentioned in this paper, the reader should 
refer to Mr. Alban Stewart’s paper “A Botanical Survey of 
the Galapagos Islands.’”*®

Abingdon, Albemarle, Barrington, Bindloe, Chatham, 
Daphne, Duncan, Gardner-near-Hood, Hood, and Indefati- 
gable islands, islet off northeast James, islets east of Jervis, 
James, Jervis, Narborough, and Seymour islands. 
Indefatigable was the center of abundance of the Galapagos 
Hawk, which was not observed at all on Charles, Culpepper, 
Tower, and Wenman. It lived in the arid or dry, and in the 
humid or moist, regions and along the seashore, being com- 
monest in the dry region. It appeared not to fly far from 
land, but evidently left the home island at times as attested
