LAMELLIROSTRAL SWIMMERS — ANSERES. 
It was seen breeding abundantly by Mr. MacFarlane near the Arctic Ocean. Some 
of the nests were found on small islets in fresh-water ponds ; others on islands in 
the Anderson, near its mouth ; and many others either on the shore or on islands 
in Franklin Bay, or other parts of the Arctic Sea. In some cases the nest was noth- 
ing more than a mere depression lined with down ; but in some the quantity of down 
was quite large. The number of eggs in a nest was generally five ; but in one case 
as many as seven were seen, and in six or seven instances six. 
On the coast of Norton Sound, Alaska, as observed by Mr. E. Adams (“Ibis,” 
1878), these Geese were observed to arrive in the middle of May in great numbers. 
They were first noticed on the 12,th. They keep much more to the sea than the other 
Geese, and large flocks are only seen inland near their breeding-places. They keep 
along the coast, out of shot, and in the spring their line of flight is directly north. 
They breed in the southern marshes with the Hutchins’s Goose, the natives collect- 
ing their eggs at the end of June, and bringing them by boat-loads to Michalaski. 
Mr. Adams regards the eggs as being by no means good eating, since they are rank 
and fishy ; but the Russians consider them excellent. 
Examples were taken in large numbers on the Yukon by Mr. Kennicott, and after- 
ward by Mr. T. Lockhart. Mr. MacFarlane found it breeding in abundance on islands 
northeast of the mouth of Anderson River, in Liverpool Bay on the Arctic coast, on 
Franklin Bay, on various other parts of the coast, and especially in regions west of 
Anderson River. 
Eggs of this species from Liverpool Bay (Smithsonian Institution, No. 9483) are 
of a dull ivory-white, or a grayish-white color, and range in length from 2.75 to 2.90 
inches, and in breadth from 1.80 to 1.85 inches.

the only American example of the species we have seen — in the much lighter color of the upper
