OCT., 1909. BIRDS OF THE LEEWARD ISLANDS CORY. 227 



Sula leucogastra (Bodd.). 



Sula sula Lowe, Ibis, 1909, p. 324. 



Common. No examples of this species were taken by Mr. Ferry, 

 but Mr. Lowe found it abundant and nesting; he says: "The nests 

 were invariably situated on the bare rocks and lined with a few pieces 

 of grass or twigs. The color of the soft parts of this Gannet were 

 taken on the spot and are as follows : Tarsi and upper surface of webs 

 bright chrome yellow; under surface of webs greenish yellow; gular 

 sac bright chrome yellow; bill yellow at base, shading off into bluish 

 gray; iris pale gray; eyelids edged with bright blue, a patch of dark 

 bluish green immediately in front of the eye." (Ibis, 1909, p. 324.) 



Family Fregaticlae. 



Fregata aquila (Linn.}. 



A number of these birds were seen by Mr. Ferry, but none were 

 taken. Mr. Lowe at the time of his visit found it abundant and 

 breeding on the island and gives some interesting notes concerning 

 its habits. (Ibis, 1909, p. 325.)
