ADDITIONS TO THE List oF Brrps GIVEN BY RIDGWAY FOR 
THE DIFFERENT ISLANDS. 
ALBEMARLE ISLAND. 
Ridgway enumerates 35 species from Albemarle, and re- 
marks: “As Dr. Baur and his associate, Mr. Adams, collected 
more than forty species in South Albemarle, there are, at least, 
twenty-five species found there which are, as yet undeter- 
mined. I cannot support this statement. Ridgway himself 
names 33 species collected by us. The following have to be 
added : Progne modesta Néboux, Coccyzus melanocoryphus Veillot, 
Fregata aquila (Linn.), Ardea herodias Linn., Phoenicopterus ruber 
Linn., Nesopelia galapagoensis (Gould), Larus fuliginosus Gould, 
Aestrelata phaeopygia Salvin., Procellaria tethys Bonaparte. 
The large white heron, of which I saw four specimens in 
South Albemarle and one in East Albemarle opposite Cowley 
Island, is certainly not a white phase of the large gray heron, 
but Herodias egretta (Gmelin). I have observed different speci- 
mens of Ardea herodias (Linn.) on South Albemarle. We have 
therefore, in all, 42 specimens of birds on Albemarle, and I do 
not believe that this number will be much increased, at least 
in the land birds, by further examination. 
BRATTLE ISLAND. 
This very small island is very close to South Albemarle. 
Besides Sula nebouxii Milne-Edwards and Creagrus furcatus 
(Néboux), Fregata aquila (Linn.) breeds there. There are also 
a few small land birds (Geospiza). 
DUNCAN ISLAND. 
To the 9 species mentioned by Ridgway the following have 
to be added. Cactornis pallida Sel. and Salv. (?) besides the 
black Cactornis sp.; Progne modesta (Néboux), Asio galapagoen 
sis (Gould), Fregata aquila (Linn.), Pelecanus californicus Ridg- 
way, Sula nebouxii Milne-Edwards; Anous galapagoensis Sharpe, 
Aestrelata phaeopygia Salvin, Procellaria tethys Bonaparte.
