Islands on their first southward migration. 

 They were weighed, measured, frozen, and 

 shipped to the Marine Mammal Biological 

 Laboratory, Seattle. Mark C. Keyes and Hiroshi 

 Kajimura examined the seals for parasites 

 and food remains. Few seals were seen on 

 St. Paul Island during a survey of all rook- 

 eries and hauling grounds 5 to 8 December. 



To supplement surveys made near the Aleu- 

 tian Islands from the Black Douglas (1947-48), 

 G. B. Reed (1965), and the Pribilof (1966), 

 we summarize the reports from other sources 

 of strandings, sightings, and land migrations 

 of fur seals in the Bering Sea and the Aleutian 

 Islands during autumn and early winter. 



Richard S. Peterson's 1 ^ 17 studies of the 

 behavior of fur seals on St. Paul Island from 

 1961 through 1963 provide the most recent 

 information on the departures of seals from 

 the Pribilof Islands. Peterson defined a period
