NO. 1265. SALMONOID FISHES OF JAPAN— JORDAN AND SNYDER. 575 
tinged; anal with dusky edging; sides of head without the dark colora- 
tion seen in the quinnat; males mostly red in autumn, and with the 
usual changes of form. Length 15 inches; weight 3 to 8 pounds. A 
small salmon, ascending streams in the autumn to no great distance. 
Abundant from San Francisco northward, especially in Puget Sound 
and the Alaskan fjords; south on the Asiatic coasts to Japan. Here 
described from Puget Sound specimens. A specimen from Otaru in 
the museum at Hakodate seems to be t3^pical of the species, the tip of 
the dorsal black, as usual. Three others from the Otaru, two from Ura 
River, and several from Osatsubo, sent by the museum at Sapporo, 
seem to be the young of this species. Four adult examples (325, 331, 
332, 337) were secured by us in the market at Aomori. 
(Kisutc/t. the vernacular name in Alaska and Kamchatka; called b}' 
the Russians Bielai/a Byha^ or whitetish).
