lO SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 66 



CEPPHUS COLUMBA 



Pigeon Guillemot 



This species was not seen on the Alaskan coast porth of the 

 Aleutians, but a few were met with on the Siberian side. At East 

 Cape I estimated there were about 150 birds flying with the circling 

 clouds of Pallas's Murres and Horned Puffins. 



URIA TROILE CALIFORNICA 



California Murre 



URIA LOMVIA ARRA 



Pallas's Murre 



All along the coast from the Shumagins to Barrow large numbers 

 of Murres were observed. Both species occur in the Pribilof Islands, 

 but north of that point Pallas's Murre is the most common. All 

 the specimens taken (St. Lawrence Island and East Cape) were of 

 this form. They nest abundantly wherever suitable rocky cliffs are 

 found. The most northern breeding colony is at Cape Lisburne 

 where natives brought out eggs nearly fresh on August 8. Most of 

 the Murres at Chamisso Island had well-grown young on August 2, 

 but a few were still sitting on their single eggs. 



Note. — On August 10, while slowly forcing our way through the ice near 

 Wainwright Inlet, we came upon a pair of small Alcida. They were swim- 

 ming in a bit of open water and allowed us to pass them at a distance of 

 not more than 50 feet. As we could not have picked them up I did not 

 shoot either but observed them closely with a good glass for about a half 

 hour. They were glossy black above, with white markings on the scapulars 

 plainly visible, and throat and upper breast black. The small size and dark color 

 of the bill were clearly noted. They were very much too small for Murres, with 

 shortef bill, and certainly were not Auklets, as the black bill and glossy black- 

 ness of the plumage indicates. I am very sure they were Dovekies, but as 

 neither was taken, and I can find no record for this part of the Arctic Ocean, I 

 make but this mention of the species. 



STERCORARIUS POMARINUS 



Pomarine Jaeger 



In Thayer and Bangs' " Notes on the Birds and Mammals of the 

 Arctic Coast of East Siberia " it is stated that " the Pomarine Jaeger 

 is much more common south of Bering Strait than northward." 

 This is doubtless true of the Siberian coast, but on the Alaskan side 

 I found them most numerous north of Kotzebue Sound. Nelson 

 speaks of their abundance at the mouth of the Yukon during the
