INTRODUCTION. 



The region covered by the present report embraces the western coast of North 

 America from the thirty-second parallel of latitude to Point Barrow on the Arctic 

 Ocean, all of Bering Sea, the coast of Asia from East Cape to Sakhalin, and the 

 Kuril Islands. It thus includes all the waters north of a line drawn from the south- 

 em end of Sakhalin to the southern boundary of the United States. Information 

 concerning the fauna of the Sea of Okhotsk is very meager; and within the region 

 outlined nothing is known concerning the starfishes of the great depths of the mid 

 North Pacific. 



In the preparation of this report six thousand nine hundred and twenty-seven 

 specimens have been listed, and many more examined. These specimens belong to 

 the following collections: 



1. The very extensive collection of the U. S. National Museum, the bulk of 

 which was obtained by theU. S. Fisheries steamer Alhatross between 1888 and 1897, 

 inclusive. The dredge hauls at which Asteroidea were taken number about two hun- 

 dred, and the specimens listed number four thousand three hundred and eighty. 

 Many specimens were taken by Dr. W. H. Dall and othei-s in Alaska. 



2. A collection made by the Albatross in Alaska in 1903, and forwarded to 

 me for report by the U. S. Bureau of Fisheries. 



3. A large collection made by the Albatross off California, principally in the 

 regions off San Diego and Monterey, during the spring of 1904, and sent to me by 

 the U. S. Bureau of Fisheries. 



4. A collection made by the Albatross during the summer of 1906, in the 

 region of the Aleutian Islands, Kamchatka, and tlic Kuril Islands. 



5. A small collection, principally from off San Pedro, California, and belonging 

 to the University of California, kindly lent b}' Prof. W. E. Ritter. 



6. The small collection of the Department of Zoology, Stanford l^niversity, 

 principally from Alaska, and Monterey, California. 



7. The Museum of Comparative Zoology, through Dr. II. L. Clark, has lent 

 several specimens for examination.
