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. (JVe/son.) 
10. Pacific Loon, 
Givia pacificus (LAwWR.) ALLEN. 1897. 
A single specimen obtained at St. Michael, Alaska, August 
25th, 1876. (Zurner.) 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. (Bzooks.) 
BREEDING NotEs.—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. (MWacfarlane.) 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 
abundance though we were unable to find the nest. One of their 
breeding grounds was evidently a swampy lagoon, some five or 
six miles inland, but the nests were inaccessible. (A/urdoch.) 
11. Red-throated Loon. 
Gavia lumme (GUNN.) ALLEN. 1897. 
This species is a common summer migrant throughout the 
northern part of the continent. It breeds in Greenland in both 
inspectorates ( Arct. Man.), and in Newfoundland in small ponds in 
tne marshes, placing its nest in a tussock of grass surrounded by 
water. (Keeks.) Not common on Ellsemere island, (4. Bay.) 
Common along the shores and islands of Hudson bay and Hudson 
strait, to the northward of James bay. Seen on the north coast 
of Greenland and in all the northern waters. Breeds on islands 
or shores of ponds, not far from coast. Feeds in the sea and 
fresh water. (A. P. Low.) A not uncommon summer resident in 
New Brunswick. (Chamberlain.) Rare migrant in Nova Scotia. 
(Hf. F. Tufts.) Abundant in Labrador, and breeding around
