58 NORTH AMEEICAN FAUNA. [no. 19. 



7. Simorhynchus pusillus. Least Auklct. 



Anklets were seen several times while we were crossing Bering Sea 

 in the Corwhi October 1-2 and increased in numbers as we approached 

 the Pribilofs. They were common with ^'arious other (unidentitied) 

 species of water ])irds off Unalaska October 4 and a])undant in Akntan 

 Pass October 0. T refer them to this species, as Nelson found it the 

 most aliundant in these waters. 



8. Brachyramphus marmoratus. Marbled Murrelet. 



This bird was fairly common in the Inside Passage Ma}^ 28-29, and 

 one was killed at Bocadequadra. We saw a few on Lynn Canal May 

 30, and I shot one near Skagway May 31. Doubtless some of the 

 many murrelets seen with auklets near the Pribilof and Aleutian 

 islands in October were this species. 



9. Cepphus columba. Pigeon Guillemot. 



Seen at Bocadequadra and along the Inside Passage May 28-29. 

 Guillemots which I saw near Unalaska October 4 were probably this 

 species. 



10. TJria lomvia arra. Pallas Murre. 



The murres seen near St. Michael August 29 and about St. George 

 Island and Unalaska in October were probably chiefly this species, 

 though some may have been Uria troile calif ornica. 



11. Stercorarius parasiticus. Parasitic Jaeger. 



Common at the Aphoon mouth of the Yukon August 27-28, and 

 about St. Michael until September 10. About this time their nvnn- 

 bers decreased, and the last one was seen September 16. All appeared 

 to be adults (as were the four collected), and only one was in the black 

 plumage. 



12. Stercorarius longicaudus. Long-tailed Jaeger. 



I saw one at the Aphoon mouth August 28, and both Osgood and I 

 occasionally saw the species at St. Michael until September 12. 



13. Rissa tridactyla pollicaris. Pacific Kittiwake. 



Adult kittiwakes were tolerably common at St. Michael from Sep- 

 tember 19 to the end of our stay, but no young were seen. As we 

 crossed Bering Sea October 1-5, and at Unalaska October 5-6, young 

 kittiwakes w^ere common, and we saw no adults except at St. George 

 and Unalaska. The irides of the adult arc vandyke brown; ring on 

 eyelid orange rufous; bill sulphur yellow, whitish at tip; gape rufous; 

 tarsi, toes, palmations, and nails slate black. 



11. Rissa brevirostris. Eed-legged Kittiwake. 



One was seen by Osgood at Unalaska (Dutch Harbor) October 5.
