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. ULAMANIA 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 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.
