104. COLYMBUS 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.

1 06. FRATERCULA ARCTICA, (Z.) 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.
