seem to breed south of 70° N. Its name, "Islandsk Ryle” is not particul- 
arly apt, as it hardly breeds on Iceland, at any rate extremely rarely, 
whereas in migration time it is met with there in large numbers. 
Four skins of this species have been sent home. 
1) June 12th, 1900. Old bird in summer dress, with many white, badly 
worn feathers mixed in the breast and belly, presumably remnants 
of the winter plumage. Wing 165 mır., Tail 62 mm., Tarsus 29 mm. 
2) August 16th, 1906. Old bird, well advanced towards winter plumage. 
3) — ist, — Young bird of same year. 
4) — 16th, — Old bird. 
DUNLIN (Calidris alpina islandica Schieler).

Its appearance at Angmagsalik must be regarded as quite casual; 
it has been seen there in May, June and August, but scarcely breeds 
there. Only occasionally met with in West Greenland, whereas it has 
been found breeding in north-east Greenland, where Bay found it in 
numbers by Scoresby Sound, without being able, however, to ascertain _ 
whether it bred there or not. Nathorst found it breeding on Claveringo 
and Manniche in large numbers at Danmarks Havn. The species is 
circumpolar, but it also breeds in parts of Central Europe. 
Four skins have been sent home. 
1) May 27th, 1902. Old bird т partly worn summer dress, dark breast- 
piece with white edges on the black feathers; breast-piece not large. 
Wing 105 mm., Tail 45 mm., Tarsus 22 mm., Bill 24mm.

The Dunlins which breed on the northern part of the east coast 
of Greenland vary in several respects from those met with in Denmark 
and are regarded by Schiøler ("Nogle Tilfojelser og Bemærkninger 
til Listen over Danmarks Fugle”, Dansk orn. Foren. Tidsskr. 
Aarg. 16) as belonging to another separate race which he calls С. alpına 
arctica; but those sent down from Angmagsalik are not of this race; 
as might have been expected, they quite agree with those breeding on 
Iceland, which Schiøler calls С. alpina tislandica. 
SANDERLING (Crocethia alba Pall.).

Petersen has only seen the Sanderling once at Angmagsalık, on 
August 22nd, 1900, when it was shot close to the colony.
