160 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



The sources from which fur seals are derived are as follows: The 

 skins known to the trade as "Alaskas" are those of surplus male seals 

 killed on the Pribilof Islands, under United States government super- 

 vision; " Copper" and " Robben Island " are similar in character, and 

 are killed on the Commander and Robben islands, respectively, under 

 direction of oiBcers of the Russian Government; "Lobos" skins are 

 those derived from the Lobos Islands in the mouth of the Rio de la 

 Plata, and are killed under supervision of the Government of Uruguay. 

 The term ''Northwest coast" is used to designate the entire pelagic 

 catch of the North Pacific Ocean and Bering Sea. Skins known as 

 "Cape Horn," " Cape of Good Hope," "Australasian," " Galapagos," 

 and "South Sea" are the result of irregular sealing in all of these 

 regions, seals being killed indiscriminately on their breeding-grounds. 

 "Unalaska" skins are those of young seals of the j^ear, commonly 

 known as " Gray Pups," and are killed by natives, in the passes of the 

 Aleutian Islands during their first southward migration.
