the tie!?h more watery and less valuable when canned. It is the piin- 
cipal salmon of Alaska, and one which merits introduction into the 
lakes of Japan. This species is very rare in Japan. In the museum 
at Hakodate is a third specimen from Akan Lake in the Province of 
Kushiro. in northern Hokkaido. This specimen, about a foot long, 
is blue above, with a few faint dark spots, silvery below. D. 11, 10; 
A. 11, 1-1; scales 135; gill rakers 15+22 = 37; B. 13. A specimen with- 
out spots in the same museum, labeled Benimasu or Red Salmon^ 
also apparentlv belongs to this species. It is from Urup Island 
(Kuriles). The two described above from Lake Akan, a little larger 
and darker in color have been received from Professor Nozawa of the 
museum at Sapporo. It is said that the species occurs in no other 
locality in Japan proper except about Kushiro Bay, into which Akan 
Lake flows, and that it never reaches a larger size. Similar dwarfish 
varieties, known as subsp. kennerlyi^ occur in lakes of Idaho and 
Washington.
