104. COLYMDUS TORQUATUS, Bnam, 

 (Great Northern Diver.) 



Is rather common. On August 2 I saw a number of them 

 near Wolf Island, and killed two ; both were immature birds. 

 Breeds. 



105. UTAMAXIA TORDA, {L.) Leach. 

 (Razor-billed Auk) 



Breeds in great numbers on Bird Rock, and is not uncom- 

 mon on Byron Island. The very young birds are covered 

 with a blackish down, having a white belly. 



106. FRATERCULA ARCTIC A, (L.) Steph. 

 (Common Pufein.) 



Breeds abundantly on Bird Rock and Byron Island. One 

 morning I counted fifty-four of them sitting in a line on 

 one of the ledges. They are quite tame, and I have often 

 approached within a few feet of them before they offered 

 to flv.
