ROUGH-LEGGED HAWK. 
I have a female shot at Herschel Island, May 21, 1914, by Mr. J. 
Heard, Jr. It contained an ovary measuring seven eighths of an 
inch. Mr. Heard found these birds very common at Herschel Island 
when he took this specimen. 
Mr. Dixon noted this species at Humphrey Point, on May 13, and 
I saw a single specimen at Demarcation Point, on May 24. 
HALIAEETUS ALBICILLA BROOKSI (Hume).

Island. 
THALASSAETUS PELAGICUS (Pallas). 
KAMCHATKAN SEA EAGLE. 
Two very large eagles were seen near the mouth of Avatcha Bay,
