Altbougii a g'reat many divisions have been establislied for the spe- 

 cies of the ohl Liuuieaa genus ^Sulmo, for the purposes of the present 

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

 -a separate section of Oricorhynchus, for the sea-salmon with permanently 

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

 lows:

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

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

 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 i 

 with strong teeth ; thie extremity of the lower jaw terminating £ 

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

 teeth. (The subgenus Oncorhynchns, Suckley.)
