much larger than those of the labials; tail rather strongly lunated, 

 and profusely dotted with elongated oval dark spots; the other fins 

 usually unspotted, adipose rather elongated ; scales much smaller than 

 those of the S. scouleri. 



The colors of this, like those of other species, vary much after 

 the fish enters fresh water. Those caught in salt water are 

 more or less silvery. After entering fresh rivers the color of 

 the upper parts becomoB of a dirty greyish yellow ; below, white 

 blotched with yellow. These colors, however, vary considera- 

 bly in different individuals. 



MaMtat.—North-we&t coast of America, entering the rivers 

 in the vicinity of Puget Sound for spawning purposes early in 

 the autumn of every alternate year. 



Dr. Kennerly, who obtained the typical specimen of the 

 present species at Anaimo, Yaucouver's Island, Sept. 22, 1857, 

 remarks in his notes that it was a male, having the " head 

 greenish yellow, clouded with black : opercula dull pinkish. 

 Upper parts dirty greyish and yellow: under parts white 

 blotched with yellow. Ventral and pectoral fins grass green, 

 dorsal ultramarine blue and green. Tail blotched (spotted ?) 

 with black." 



The teeth on the limbs of the lower jaw of this specimen extend 

 backward only half their length. Tongue apparently destitute 

 of teeth. Branchial rays 11. 11.* Total length 25J inches. 

 Length of head T inches. Depth of hump 7 inches. 



This species, according to the residents of that portion of the 

 world — both whites and natives— appears only biennially, 

 choosing the "odd" years. On its first arrival it is fat and of 

 good quality, but soon becomes lean and unsavory. In many 

 respects this fish strongly resembles the Gokbuscha, or Swrvp- 

 hacked Salmon of Kamtschatka, spoken of by Pennant, and
