ANNOTATED LIST OF SPECIES. 



1. .ffichmopliorus occidentalis. Western Grebe. 



Several seen at Bocadequadra, near Dixon Entrance, Ma}^ 28. 



2. Colymbus holbcelli. Holboell Grebe. 



A young- male was taken on the ' Canal ' at St. Michael September 

 22. The irides were primrose yellow; basal two-thirds of the culmen, 

 outside tarsi, and lobes, seal brown; rest of bill, ocher yellow; inside 

 of the tarsi and lobes, maize yellow; nails, yellowish olive buff. 



3. Gavia imber. Loon. 



Seen at Bocadequadra May 28 and in the Inside Passage May 29. 

 Several seen on Lake Bennett and a pair at Caribou Crossing between 

 June 17 and 28. On Lake Marsh they were common and were fre- 

 quently heard, especially at night. The last loon certainly referable 

 to this species was seen there July G. 



4. Gavia arctica. Black-throated Loon. 



A loon that flew over our boat on Thirty-Mile River July 18, and 

 another seen near Big Salmon River July 20, I believe were Oavla 

 arctica. I saw several loons at the Aphoon mouth of the Yukon 

 August 27 and one at St. Michael on September 5 and 16. We obtained 

 none of them, but the experience of others makes it probable that all 

 were the black-throated. Dr. Romig, of the Moravian Mission on the 

 Kuskokwim River, told me that his party killed two on August 27 on 

 the portage from Bethel on the Kuskokwim to Hendricks Station on 

 the Yukon Delta. 



5. Lunda cirrhata. Tufted Puffin. 



Osgood saw one at Whale Island, near St. Michael, September 8. 



6. Fratercula corniculata. Horned Puffin. 



We took two and saw about a dozen puffins near Whale Island Sep- 

 tember 8. Irides, drab gray; ring on eyelid and lip of l)ill, flame 

 scarlet; rest of bill dull straw yellow; bare skin at gape and line along 

 base of maxilla, cadmium yellow; line below lower ej'elid and horns, 

 black; palmations, cadmium orange; tarsi and toes, cadmium orange 

 above, chrome yellow below; nails varying from drab gray to slate 

 color.
