1912 BIRDS OF SOUTHERN CALIFORNIA 19 



April until November. T have taken many specimens of this bird alont^ the 

 southern California coast and around the Santa Barbara Islands. 



45. (96) Puffinus tenuirostris (Temminck). Slender-rilled Shear- 

 water. 



An inhabitant of southern oceans, occurring irregularly north ak)ng the 

 California coast in winter. It was noted at Monterey by J. Mailliard, Decem- 

 ber 17. 18 and 19, 1895 (Auk xv. 1898, 197), and by R. H. Beck, October U 

 and December 2, 1907, and January 30. 1908 ( Proc. Cal. Acad. Sci., ser 4, 

 vol. in, 1910. 66). The only record I have seen for southern California is 

 of a specimen taken from a small flock by A. W. Anthony, near San Diego. 

 January 9, 1896 (Auk xiii. 1896, 171). 



46. (105) Oceanodroma furcata (Gmelin). Forked-tailed Petrel. 

 There has been practically nt) systematic study of the Petrels along our 



southern California cx)ast. The birds are very difficuh to collect during mi- 

 orations, and there are not enough specimens in collections from this locality 

 to enable us to arrive at a definite conclusion as to the comparative abundance 

 of the different species. The Forked-tailed Petrel occurs in migrations along 

 the California coast, south at least to Los Angeles County. It was noted by 

 R. H. Beck at Monterey in June. 1895. and November. 1903 ( Proc. Cal. Acad. 

 Sci., ser. 4, vol. iii, 1910, 66). It is recorded from off San Pedro by J. G. 

 Cooper, who saw a specimen that was taken there by Mr. Lorquin and pre- 

 sented to the State Museum (Proc. Cal. Acad. Sci., iv. 1868. 10). Mr. Grinnell 

 informs me that this specimen is now no. 4470. collection University of Cali- 

 fornia Museum of Vertebrate Zoology. The label in Dr. Cooper's handwrit- 

 ing says "San Pedro Bay. Cal.. 914, J. G. C. Shot by Lorquin. Exch." 



47. (105.2) Oceanodroma kaedingi Anthony. Kaeding Petrel. 



A. W. Anthony described this species from Lower California, and was under 

 the impression that it bred there and occasionally straggled north to southern 

 Cahfornia in migrations (Auk xv, 1898, Z7 , 38). Recent investigations have 

 shown, however, that it breeds to the north of us. and occurs in migrations along 

 the whole California coast, south to Lower California. L. H. Miller has an adult 

 male which flew on board the ship Albatross, while otif San Clemente Island, 

 March 22, 1904. 



48. (107) Oceanodroma melania (Bonaparte). Black Petrel. 

 Common out at sea during the entire year. Least plentiful during July and 



August, at which season it breeds on the islands oiT the coast of Lower Califor- 

 nia, from Los Coronados southward. Straggles north at least to Monterey. 



49. (108) Oceanodroma homochroa (Coues). Ashy Petrel. 

 Probably occurs on the ocean off the coast of California throughout the year. 



An adult from San Miguel Island (now in British Museum), was given to II. 

 W. Henshaw by Captain Forney of the Coast Survey, who stated that the species 

 bred on San Miguel in great numbers ( Ann. Rep. Ch. En. C. S. G. S.. 1876. App. 

 TI, 277). In Tune, 1910, I made particular search for this bird on San Miguel 

 but failed to find it. 1 may possibly have overlooked it or it may not occur there
