fore probably with nasal tubes and curved upper mandible; 
but even supposing that Mr Joensen has observed only the 
last fact, he adds that it also differed in colour from the 
young Gannets; both deviations, 2.e., that of bill and colour, 
cannot easily be supposed united in the same abnormity. 
It is just as unlikely to have been a hybrid between 
two birds differing as widely as a Gannet and an Albatross, 
species that are no more closely allied than Penguin and 
Diver, far more different than cat and dog. Only the third 
possibility remains: it has been a young Albatross; every 
item in the short description corresponds ; the bird-catchers 
of Myggenaes have surely been right in supposing it to be 
“the young of that bird.” Its being the single specimen 
of its species in the island does not speak against it. It is 
said to migrate every year to the south with the Gannets, 
z.¢., its migration occurred at the same time as that of these 
birds; but it is not probable that it has accompanied them 
constantly during the winter season, if only for the reason 
that its food is different in kind from that of the Gannets. 
It is more likely that the Albatross, as a more powerful flier, 
has ranged considerably farther south, far beyond the 
Equator; and here it would meet with birds of its own 
species, just at the beginning, or immediately before, the 
breeding season on the southern hemisphere; here it prob- 
ably dwelt until its instinct again took it back to Myggenaes 
Holm. There is even a probability that it, at least once, has 
been accompanied by a mate: perhaps the Albatross shot at 
Spitzbergen, a bird in full plumage, consequently capable of 
breeding, may have accompanied it to the northern latitudes. 
At all events, it must have passed the Feerde Islands on its 
way to Spitzbergen. In this connection I shall mention an 
observation by Mr Harvie-Brown, published in Zhe Zoologist 
(September 1894, pp. 337, 338): off the Orkneys, twenty 
miles from land, he saw (July 18, 1894) an undoubted 
Albatross of the same size as the one living in the Ferée 
Islands, but “distinctly an immature bird”; perhaps a full- 
erown young of the Albatross of Myggenaes Holm! 
But if an Albatross can exist on the Fzerde Islands during 
so many years, and breed there, the question suggests itself:
