large numbers, and fairly regularly during migrating time about the 
middle of May and September. 
The King Eider, which also breeds farther north on the east coast, 
has been seen once or twice. The two kinds of diving birds which in 
south-west Greenland appear in enormous numbers in winter, the 
Brünnich’s Guillemot and the Little Auk, are also to be found in winter 
at Angmagsalik. The Guillemot has been met breeding in fairly large 
numbers on the north-east coast of Greenland. The Little Auk has 
been seen there in numbers, for instance by Bay in Scoresby Sound; 
it has not been seen breeding, it is true, but there is hardly any doubt 
that it does. The two species scarcely leave the coast of Greenland to 
go further south, or rather, they only allow themselves to be driven 
away from the coast when the ice forms a barrier, and then they keep 
to the open sea among the field-ice. 
The foregoing has shown that at Angmagsalik in winter there regu- 
larly appear larger or smaller numbers of the species which breed farther 
north, but which are not migratory birds in the sense that they leave 
the coasts of Greenland. As regards those species which are real migratory 
‘birds and breed in the northern part of the east coast, it is apparent 
that for most of them their flight does not regularly take its course 
over the Angmagsalik district. If this were the case, large numbers 
must be met with occasionally; but those which have been seen have 
almost in every case only been single individuals. A glance at the map 
will show, in fact, that the birds which have wintered on the coasts 
of Europe and are on their way to north-east Greenland, might be 
expected to travel the course over Scotland, Iceland or over West 
Norway, the Faroe Islands, Iceland, and from there hit the coast of 
Greenland at about 70°, in the area round Scoresby Sound. 
The only species which apparently to a greater extent directs its 
migratory course over the Angmagsalik district is the Brent Goose, 
a bird which in north-east Greenland is only rarely met as a breed- 
ing bird, even although a number of flocks were seen on the Den- 
mark Expedition. There is something strange in the fact that just 
this species appears at Angmagsalik at migration time in such large 
numbers, and I believe that the explanation is that it is certainly 
migrating, not northwards, but on the contrary across the inland ice 
to the West Coast; the inland ice, which at this point is hardly 60 
miles broad, certainly cannot be any obstacle to a bird like the 
Brent Goose. That this must be so is supported by the observation made 
by Johan Petersen of the direction of the flight of the Brent Goose, 
which in the spring has been from east to west, and in the autumn 
in the contrary direction. 
The species which belong to this group are:
