found breeding as far north as in Scoresby Sound, whereas only one 
was seen on the Denmark Expedition. On Iceland it is a common breed- 
ing bird, as also in the western parts of Arctic North America. 
Two skins of old birds in summer dress were sent home in 1895; 
these were presumably a pair, as the measurements also indicate :— 
Wing 360 mm., Tail 70 mm., Tarsus 90 mm., Culmen 75 mm. 
Wing 380 mm., Tail 70 mm., Tarsus 95 mm., Culmen 82 mm. 
RED-THROATED DIVER (Colymbus stellatus Pont.). 
Rodstrubet Lom. E. Gr.: Kakorkak (from the voice.) 
Like the foregoing species, this is common everywhere at Ang- 
magsalik, breeds in large numbers around the lakes. It arrives some- 
what earlier than the Great Northern Diver, about the middle of May 
or before that time. The breeding time is, like that of the G. N. Diver, 
June and July; the first egg is mentioned June 10th (1913). Eggs were 
often brought to Petersen in July, sometimes in fairly large numbers, 
but most often set. 
Everywhere in West Greenland and up to Upernivik the species 
is common, and has also been met with frequently in East Greenland 
up to 75° N. On the Denmark Expedition from about 77° to about 
80° N. it was not seen. It is common in the circumpolar areas, and breeds 
at Spitzbergen, Iceland, the Faroe Islands and in eastern North 
America, etc. | 
FULMAR (Fulmarus glacialis glacialis L.). 
Stormfusl. Е. Gr.: Kakugdluk. 
This species keeps to the Danmark Strait and only comes in to the 
coast when the field ice has disappeared, then being sometimes taken 
by the Greenlanders with the bird-dart. Only once, September 25th, 
1908, did Petersen see it in Tasiusak itself. It is not known to breed 
in the vicinity. 
The Fulmar is a common circumpolar species, its breeding zone 
stretching down to the Faroe Islands, the northern parts of Great 
Britain, and Norway. In Greenland it is found everywhere along the 
coast, breeds particularly in the northerly parts of West Greenland 
Along the East coast it has been met with frequently by all expeditions, 
but as a breeding bird only by the Denmark Expedition in lat.81°12’N.; 
a large colony was found on a mountain there. 
The skin of an old bird, blue-grey on the back, white on the wings, 
was sent home; it was shot in September, 1901. The measurements 
were: Wing 300 mm., Tail 114 mm., Tarsus 20 mm.
