Although I have not seen a specimen of the dark-colored Sula found 

 in the Galapagos, I have no doubt the species mentioned by Sundevall 

 and Salvin under the name leiicogastcr is in reality S. hreicsteri, which is 

 the Pacific coast representative of 8. leu cog aster, the latter being appar- 

 ently confined to the Atlantic side of the continent.

Range. — Intertropical seas in general, north, in America, to Florida 

 and Lower California; Galapagos Archipelago: Indefatigable and 

 Tower islands (Baur and Adams); Wenman Island (Townsend). 



The five specimens in Dr. Baur's collection, and Mr. Townsend's 

 Wenman Island bird, although unquestionably adults, with deep red 

 feet and other evidences of full maturity, are all in the gray plumage. 

 All have gray tails, and only one, a male from Tower Island, has any 

 portion of the plumage inclining to white, the lower parts ])osterior to 

 the breast being soiled white (i)urer beneath the surface) and the pos- 

 terior scapulars and longer ui)i)er tail-coverts wliitish. 



Mr. Adams' fresh color-notes on these specimens are as follows: 



Legs and feet a trifle more red and purple than madder brown; beak with just a 

 little more blue than lavender-gray; bare skin across forehead and on sides of man- 

 dible next to horny portion same as legs, but paler; around eye a little more blue 

 than beak; augle of jaw next feathers and on throat between rami dark purplish.
