Figiu-es. — A young fish called by this name, and probably belonging to the

 volume on the fishes collected by the United States Pacific Railroad sur-

Sp. Ch. — Adult. — Head pointed and large, forming about a fourth of 

 the length from the snout to the end of the scales on the caudal. Dor.

This being the most important salmon, both in excellence and numbers, 

 found in the western waters, I have taken the liberty of reproducing a 

 portion of the remarks on the species which were embodied iu the report
