LONG-TAILED SKUA (Stercorarius longicaudus Vieill.). 
Lille Kjove. E. Gr.: Isinsak, Meriarsarisek = He who makes 
them vomit. 
This bird, which is so often seen in northern Greenland, has only 
been met with once at Angmagsalik, Petersen having received one shot 
on September 21st, 1905, at the mouth of Tasiusak. 
In West Greenland it breeds commonly in the northern areas, 
has been found breeding on the east coast at Scoresby Sound and 
Franz Josephs Fjord. At Danmarks Havn it was very common, and 
was seen right up to 81° №. 
BLACK GUILLEMOT (Uria grylle L.). 
Tejste. E. Gr.: Nuerniagak = He whom one catches with the 
bird-dart. 
The Black Guillemot is one of the more common birds at Ang- 
magsalik, breeds here and there in the district in no small numbers, and 
is a stationary bird, inasmuch as it holds out as long as there is open 
water or even openings in the ice, and only yields when the waters are 
entirely frozen over. In the severe months after the turn of the year 
it is one of the few birds met with in the district, as it is able to live 
even in the small openings which are constantly being formed in the 
Angmagsalik Fjord, which is so rich in current openings; indeed at times 
an opening on a stream is sufficient for it. But in any case it is only 
found in small numbers in winter. As soon as open water appears in 
the fjord or by the coast in May, the Black Guillemot again arrives in 
large numbers. Breeding time is not until June, at which time Petersen 
has often received eggs. In the autumn it keeps in to Tasiusak in fairly 
large numbers, 24 having been reported shot on one day (October 29th, 
1902). 
Everywhere along the west and north coasts of Greenland the Black 
Guillemot is a very common breeding bird; has also been seen breeding 
in the northerly parts of the east coast. Manniche found it breeding in 
about lat. 70° N. and above 80° N. it was seen on the Denmark Ex- 
pedition. It breeds everywhere by the coasts in the northern seas, dis- 
tributed in several races. As Petersen has not sent any skins home, it 
cannot with certainty be decided to which race the Black Guillemots 
at Angmagsalik belong; presumably they are of the race grylle grylle.
