at Burrard inlet and Howe sound, and also in the interior of British 

 Columbia." Brooks says a few breed in the valley of the lower 

 Fraser and that it is a scarce summer resident in Cariboo district, 

 B.C. 



Breeding Notes. — ^This species breeds at the 'mouth of the 

 Mackenzie river, for one of my collectors sent me eight eggs with 

 the skin of the parent bird. The nest was found on June 19th, 

 1894. It was built on a high bank, near some ice-floes, under 

 sticks piled up by overflow water in the spring. One of the eggs 

 in the nest is a runt, one-third the usual size. The eggs of this 

 bird have seldom been obtained in North America. It breeds in 

 Iceland, and lays from six to eight eggs, seldom more. They are 

 similar to those of the gadwell and baldpate, but average larger, 

 and are of a deeper buff tint. (Raine.) 



The nest and eggs of this species were not procured by me, and 

 the only nest I ever saw was near IliuHuk village, on Unalaska 

 island. Two immense blocks of rocks had become detached from 

 the cliff above, and when they fell their edges formed a hollow 

 place beneath. Under these rocks I discovered a deserted nest, 

 which the native who was with me asserted was that of a bird of 

 this species. The form was similar to that of the nest of H. hyema- 

 lis, and in fact so closely resembled it that I persisted in it being of 

 this bird until the native asked me if I did not know that the "Old 

 Squaw" did not build in such places. (Turner.)

Now extinct. Formerly abundant on the Labrador coast and 

 perhaps in Hudson strait and bay. Mr. William Dutcher, in an 

 able paper published in The Auk, for January, 1894, shows, although 

 1852 has been given as the date when the last specimen of this 

 species was killed, that from that date to 1875 occasional speci- 

 mens were taken and vouched for as being seen in the flesh. He 

 can find no trace of the bird having been seen since 1875 and reluc- 

 tantly concludes that it is extinct.
