THE BIRDS OF THE PRIBILOF ISLANDS. 383 



16. Oceanodroma furcata (Gmel.). Forked-taileil Petrel. 



Ooeanodroma furcala, A. 0. U. Ch. List, 1895, 36.— Coues, Key, 1890,782.— Salvin, Cat. B. Br. 

 Mus. XXV, 1896, 357.— RiDGWAY, Man. 1896, 70. 



A fresh specimen was picked up on a beach of St. Paul by Mr. F. W. True. It is 

 found throughout the Aleutians, breeding on many of the islands and may often occur 

 about the Pribilofs. Also, it is possible that they may breed about the interior of 

 St. Paul, visiting, as is their habit, their burrows at night. Several suspicious places 

 that I saw about Boga-slov maybe thus explained. A second specimen was picked up 

 near the head of the lagoon on St. Paul and preserved as a skeleton by Prof. d'Arcy 

 Thompson about August 12, 1897, as I am informed by Mr. Lucas. No. 151464, 9 , 

 July 12, 1895, St. Paul, F. W. True. 



Order PYGOPODBS. Diving Birds. 



Family GAVIIDAE. Loons. 



, Loons are seldom seen, but may occur in numbers during the winter and migra- 

 tions. Other species than those mentioned undoubtedly occur. 



17. Gavla adamsii (Gray). Yellow-billed Loon. 



G[^olyml>u8'\ t[or<j"wat«s] adamsi, CouBS, Key, 1890, 790. 



Vrinator adamsii, Townsend, Cruise, Corwin, 1887, 98. — A. O. U. Ch. List, 1895, 4. — Ridgway, 



Man. 1896, 5. 

 Colymius adamsii, Grant, Cat. B. Br. Mus., 1898, 500. 



One of this species was killed by a native in August, 1885, on St. Paul, as men- 

 tioned by Mr. Townsend in the cruise of the Corwin. The specimen was preserved 

 for one of the Treasury agents, who. informed me in 1890 that he still had it. 



18. Gavia arctica (Linn.). Black-throated Loon. 



ColymJ)Us arcticus, CouES, in Elliott's Ept. Aff. Alaska, 1873; Reprint, 1875, 201 ; Key, 1890, 791.—

1896, 7. 

 Colymhus padficus, Grant, Cat. B. Br. Mns., 1898, 494. 



Mr. Elliott, while surveying Zapadni on St. George in 1873, found a nearly dead 



individual which had been thrown ashore by the surf. It was an adult male and the 



natives who saw it agreed that it was very rare. While on the Bush, off the north 



shore of St. Paul on August 7, 1890, Mr. Elliott and myself saw a loon which may 



have been of this species. No. 64303, U.S.N.M. ad. 3 June 22, 1873, St. George, H. W. 



Elliott. 



Family PODICIPIDAE. Grebes. 



Owing to obvious difficulties it is not possible to procure many of these birds 

 about the islands. I saw none; they are seldom seen. 



18. Colymbus holboellii (Reinh.). Holboell's Grebe. 



Podicepa griseigena, Coues, in Elliott's Rpt. Affairs, Alaska, 1873; Reprint, 1875, 201. — Elliott,

 Podieeps griseigena holboellii, Coues, Key 1890, 749. 

 Colymbus holboellii. Nelson, Bds. AlpiSka, 1887, 35.— A. O. U. Ch. List, 1895, 1.— Ridgway, Man. 



1896, 5. 

 Podiapes holboelli. Gkant, Cat. B. Br. Mus., 1898, 542. 



Presumably uncommon during the fall and winter. Mr, Elliott obtained one on 

 St. George; 'No. 64302, im. o, U.S.N.M. Coll. June 22, 1873.
