melanophrys has been met with as far north as lat. 24° S., 
at Gladstone, Port Curtis, Queensland, though only on one 
occasion (Ramsay, 30). Between the Australian Continent 
and New Zealand it is very common (Layard, 9). It was first 
introduced into the avifauna of New Zealand by Finsch (15) 
in 1867, Finsch (27) and Buller (46) both considering it as 
one of the most common species of Albatross in the waters 
around New Zealand. It is, moreover, observed in nearly 
all groups of islands to the east and south (Kermadec, 
Chatham, Bounty, Antipodes, Auckland, and, farthest south, 
Campbell Islands, about 53° S.). Its range extends surely 
far north of these islands. Layard (29) includes it in the 
Fiji Island avifauna, but only because a specimen is said to 
have been met with at Kadavu (lat. 19° S.); farther north 
it has not been observed. From the wide stretch of water 
between New Zealand and South America, observations as 
to the occurrence of this bird are almost wanting. On the 
coast of Chili it is recorded from Talcahuano Bay (lat. 
354° S.; Salvin, 39) and from Valparaiso (33° S., August 
13, 1879; Sharpe, 35); the latter point seems to be the 
most northern locality where it has been observed on this 
coast; farther north, at Callao Bay, Peru (lat. 12° S.), occurs 
a closely allied species, D. irrorata (Salvin, Proc. Zool. Soe., 
1883, p. 430). Towards the south it ranges beyond the 
southern extremity of America, as it has been seen by 
Buller (50) near the island of Diego Ramirez (lat. 56° S.; 
March 16), by Tschudi (4) even in lat. 57° 20’ S., the most 
southern locality where the species has ever been observed. 
D. melanophrys is said to have been met with twice far 
north of its usual range. The first case is mentioned by 
Bean (38): a specimen was seen, October 31, 1880, about 
1060 miles west of Cape Mendocino, California, in lat. 40° 
30' N., long. 142° 23’ W. For this reason the species has been 
included in the lists of the North American avifauna. It is 
not quite certain, I think, that the bird observed by Bean 
was a D. melanophrys and not a D, tmmutabilis.: 
1D. immutabilis has its breeding-places in the island of Laysan in the 
Pacific (about lat. 26° N.; Rothschild, Proc. Zool. Soc., 1893, p. 505); moreover, 
it has been met with at Miyakeshima, Japan (about 34° N.; Rothschild, [bis,
