104. CO LYME US TORQUATUS, Brunn. 

 (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. UTAMANIA TORDA, (Z.) 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 ARCTICA, (L.) Steph. 

 (Common Puffin.) 



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 fly.
