Introduction vii 



scales along the lateral line, and eighteen oblique 

 or horizontal rows between the lateral line and 

 the ventral line. The number of rays in the fins 

 and the number of scales along the lateral line, 

 as given, represent the average number, and are 

 subject to slight variation ; thus in some localities 

 the number of rays in a fin may be found to vary 

 one or two, and the number of scales along the 

 lateral line may vary from one to five, more or 

 less, from the number given in the descriptions. 



I have adhered strictly to the nomenclature of 

 the " Fishes of Middle and North America " 

 (Bulletin, U. S. National Museum, No. 47), by 

 Jordan and Evermann, and in the main I have 

 followed the descriptions as recorded in that 

 admirable work; but in many instances I have 

 depended on my own notes. 



The suggestions as to angling and the tools 

 and tackle recommended may be confidently 

 relied on, as they are in conformity with my own 

 practice and are based on my personal experience, 

 covering a period of forty years, on many waters, 

 from Canada to the West Indies, and from the 

 Atlantic to the Rocky Mountains.
