latitude 35° 14’ N., longitude 132° 49’ W., they were particu- 
larly common, a score or more often being in attendance on the 
Academy; eighteen were caught with hook and line. During 
the Revilla Gigedo Expedition, in 1903, the last one on the 
passage south was seen May 9 off Natividad Island, about lati- 
tude 27° N. On the return voyage the first were met with 
July 19, in latitude 24° N., longitude 122° W. Mr. A. W. 
Anthony reports a solitary individual in May in the vicinity 
of Clarion Island, about latitude 19° N.* It therefore appears 
that the southern boundary of this albatross’s range on the 
American side of the Pacific is near the Tropic of Cancer. 
Inshore in the latitude of middle California, Black-footed 
Albatrosses are apparently of irregular occurrence, but off- 
shore they seem to be present the year round, indicating that 
all the individuals of the species do not occupy the breeding 
stations at the same time of the year. 
Diomedea albatrus Pallas: SHORT-TAILED ALBATROSS 
Coves—Diomedea brachyura, V, 177, 187; (?) D. leptorhyncha, V,

It has not been satisfactorily determined how far south this 
albatross ranges, several other albatrosses having been con- 
founded with it. Dr. Brewer’s account of this species in The 
Water Birds of North America clearly relates to three alba- 
trosses, the Short-tailed, the Black-footed, and the Laysan. 
Off Point Pinos, California, I found the Short-tailed Alba- 
tross quite common in December, 1894, and January, 1895,” 
and again during the latter half of September, 1896.° It 
seems, nevertheless, to be of irregular occurrence in that 
vicinity, for it escaped the observation of Mr. R. H. Beck dur- 
ing several seasons between 1903 and 1910, and was not met - 
with by myself during December, 1912. Its presence off 
Southern California is well authenticated. However, in some 
instances the Laysan Albatross may have been mistaken for
