Mr. Ridgway's A Nomenclature of Colors was used in 

 determining colors. 



In closing, I would say that since April 1, 1904, the day I 

 first began the study of ornithology, there has always been at 

 my hand a gentleman who has never withheld from me the 

 fruit of his own labors. To Mr. Leverett Mills Loomis, as 

 head of the Department and friend, I owe a deep debt of 

 gratitude. 



Nesopelia galapagoensis : Galapagos Dove 



Abingdon, Albemarle, Barrington, Bindloe, Charles, Chat- 

 ham, Culpepper, Daphne, Duncan, Gardner-near-Charles, 

 Gardner-near-Hood, Hood, Indefatigable, James, Jervis, Nar- 

 borough, Seymour, Tower, and Wenman islands. 



The Galapagos Dove was common on Hood, Gardner-near- 

 Hood, Duncan, James, and Abingdon islands. On Indefatig- 

 able Island it was abundant on the northwestern portion, and 

 common on other parts. On Duncan Island it appeared to be 

 restricted almost entirely to the floors of the two craters. On 

 the remaining islands it was not common — particularly on 

 Chatham, where it was decidedly rare. 



The doves appeared to vary in abundance about the springs 

 and water-holes at different times of the year, being more 

 plentifttl in the dry season than in the wet. During the latter 

 season they are no doubt dispersed more widely over the coun- 

 try on account of the generally distributed water-supply. 



Except on Charles Island, this dove appeared to occur 

 almost entirely in the dry region of the islands. On that island, 

 however, it was found, in all but one instance, about the 

 springs in the rather humid interior. Its presence in the 

 moist region of southern Indefatigable seemed to be governed 

 by the weather; on warm, clear days it was met with, while 

 on overcast, rainy days it was not seen. 



Specimens taken on Hood Island, September 25, 1905, 

 showed no particular enlargement of the reproductive organs. 

 Nevertheless, the organs of birds taken on Wenman Island, 

 September 24, 1906, were large, the breeding season for this 

 species being later in the northern than in the central and 

 southern islands — a point also noted in other species.
