during the Arctic Expedition 1875-76. 409 
tered at intervals along the coast; and a nest, scraped in the 
gravel and containing two eggs, was found 27th June, about 
three miles north of our winter-quarters. During the first 
week in August we found a pair of young birds nearly ready 
to fly in lat. 81° 50' 1ST. 
-f-I2. Pagophila eburnea. Ivory Gull. 
One of the Gulls most frequently observed in Smith Sound, 
but not beyond latitude 82° 20' N. I found a pair nesting- 
in a lofty and inaccessible cliff near Cape Hayes on the 16th 
August, 1875. On 1st September a single example flew 
around the f Alert 3 when she lay moored to the ice in Lincoln 
Bay (lat. 82° 6' N.). On the 2nd August, 1876, I observed 
one of this species near Cape Union; on the 12th August 
they were common in Discovery Bay, and from there south¬ 
ward to the north water of Baffin Bay. 
-f-13. Bissa tridactyla. Kittiwake. 
I saw a few examples of this species flying over the open 
water in the vicinity of Port Foulke, 28th July, 1875 ; but we 
did not observe it to the northward after entering the ice of 
Smith Sound; and in 1876 no specimen was seen as the ex¬ 
pedition returned south, until the north water of Baffin Bay 
was reached. 
-f-14. Larus glaucus. Glaucous Gull. 
We did not find this species breeding north of Cape Sabine; 
but stray individuals were observed as far north as lat. 82° 34'. 
The 1st September, 1875, was the latest date in the autumn 
on which I noticed this species; and it reappeared in the vici¬ 
nity of winter-quarters (lat. 82° 27' N.) in the middle of June. 
-U15. Stercorarius longicaudatus. BuffinPs Skua. 
This was the only species of Skua Gull that I met with in 
Smith Sound ; it arrived in the neighbourhood of our winter- 
quarters during the first week of June, and in considerable 
numbers. After that date it was to be seen during every hour 
of the day quartering the fells and searching for lemmings. 
It lays its two eggs in a small hollow in the ground, and de¬ 
fends its nest with the utmost bravery. On several occasions
