110 University of Washington Publications in Biology [Vol.2. 



To be more certain of your identification, the specimen at hand 

 should be compared with a description of that species. Good de- 

 scriptions and some figures of most of the American fishes may be 

 found in the publication "Fishes of North and Middle America" by 

 Jordan and Evermann, 1896 to 1900, Bulletin 47, Parts I to IV, 

 United States National Museum. 



No bibliography of the fishes of Washington and Oregon is 

 given in this publication. However, if the reader is interested in ob- 

 taining a nearly complete list of papers on the fishes of this area it 

 may be found in the Journal of the Pan-Pacific Research Institute 

 which appears as a section of the Mid-Pacific Magazine for 1935 

 and 1936, entitled "Fishes of the American Northwest. A catalogue 

 of the fishes of Washington and Oregon with distributional records 

 and bibliography" by Leonard P. Schultz and Allan C. DeLacy. 



In the preparation of keys as complicated as these, it is likely 

 that mistakes were made. Though they have been used for several 

 years by students of ichthyology at the University of Washington, 

 should errors be found the author will be pleased to have the op- 

 portunity of correcting them.
