wise like the summer plumage. " Yuuwj, first winter : Recognizable by its smaller and weaker 

 bill, by the duller and more brownish black of the upper parts, almost wanting in gloss, and by 

 the greater extension of the white upon the sides of the hind head and neck. The scapulars and 

 coverts are conspicuously marked with wiiite, as in the adult. The feet are mostly dusky " (CouKs).

The Little Auk is the most decidedly oceanic, and also one of the most Arctic, of 

 the family of Alcidiv. It lives and spends most of its time on the open sea, and very 

 rarely resorts to the land — never doing so voluntarily, except during the breeding- 

 season. It breeds exclusively in high northern regions — chiefly on islands — and 

 always in places near the ocean. 



It is found in the Arctic regions of America and Europe, and the islands in the 

 Arctic Ocean, and in the northwestern portions of Asia, on tlie isLands of Nova Zem- 

 bla and Spitzbergen. In the last-named place Messrs. Evans and Sturge met with 

 these birds in immense flocks. In one locality a great number of them were seen by 

 these naturalists flying in and out of the clilfs ; and one of the party was let down 

 into close proximity with the nests by means of a wire rope. But it was found tliat 

 this bird builds in such deep and narrow crevices that it was only after much hard 

 labor, and by breaking the rock with a hammer, that the hand could be inserted so that 

 the nests could be reached ; and even then only tliree eggs were procured. Pro- 

 fessor Newton also found this species numerous almost beyond belief on the greater
