east (Kwmelin) along the whole Arctic coast (Kichardson), and 
very abundantly along the shore of Behring Sea and in the in- 
terior of Alaska as far as Fort Yukon. (JVe/son.) A few have 
been taken at Burrard Inlet, B.C.; also at Dease Lake, Cassiar, 
B.C. (annin.) 
BreEpinc Norrs.—In spring the Black-throated Loons arrive 
rather late, coming to the vicinity of the Yukon mouth from the 
Isth to 25th May. They appear singly, and are soon after found 
scattered in pairs among the numberless ponds in the marshes 
along the coast. The eggs are usually placed upon some small 
islet in a secluded pond. There is no attempt at a nest, and 
frequently the eggs lie in a spot washed by water when the wind 
blows from the right quarter. In spite of this, however, the 
young are duly hatched, and by the first of July may be found 
swimming about with their parents. The eggs are dark olive, 
blotched with black spots, which are generally confluent at the 
larger end. Very frequently the spots are crowded into a black 
patch at the very apex of the larger end. (WVelson. ) 
MUSEUM SPECIMEN. 
One specimen—a male—obtained by Dr. R. Bell in Hudson 
Bay in 1884. 
10. Pacific Loon. 
Gavia pacificus (LAWR.) ALLEN. 1807. 
A single specimen obtained at St. Michael, Alaska, August 
2sth, 1876. (Zwrner.) Quite common at Point Barrow, and evi- 
dently breeding. The greater number, however, pass to the 
eastward. (Murdoch.) North to Arctic coast. (Ross.) Only 
once observed this bird in the lower Fraser valley, during very 
cold weather, and shot it. (Bvooks.) 
BREEDING Nores.—This is the most abundant diver in the 
region investigated. Nests were discovered in the wooded coun- 
try, in the Barren Grounds, and on the shores and islands of the 
Arctic Sea. In all about one hundred and sixty-five nests, most 
of which contained two eggs, were secured in the course of the five 
seasons from 1862 to 1866 inclusive. (Macfarlane.) This species 
arrives early in June at Point Barrow, and, as the ponds open, the 
birds make themselves at home there, and evidently breed in
