92 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Altbougli a g^reat many divisions have been established for the spe- 

 cies of the okl Linnseau genus Salmo^ for the purposes of the present 

 report it will be sufficient to consider them all as one, only recognizing 

 a separate section of OiicorhynchuSj for the sea-salmon with permanently 

 hooked bill. For convenience, however, we may arrange them as fol- 

 lows: 



I. Anadromous salmon. Species running up into fresh water to 

 spawn; the young remaining there for a greater or less time, then 

 returning to the sea, in which they continue to abide, except during 

 the period of reproduction. (Salmon.) 



a. Intermaxillaries of the fresh-run adult male fish or those just 

 from the sea, long, decurved, projecting and hooking downward 

 considerably beyond the top or knob of the lower jaw ; well armed 

 with strong teeth ; the extremity of the lower jaw terminating 

 in a broadly dilated knob, similarly armed with strong, hooked 

 teeth. (The subgenus Oncorhijnchus, Suckley.)
