Examination of a very large series of "Mullet" and "Red Horse" 

 from various i>arts of the country has led me to the conclusion, at first 

 rather unexpected, that all the various forms included in the above 

 syponymy belong to one widely diffused and somewhat variable species. 



The "Mullet" of the lakes and of Eastern Pennsylvania appears gen- 

 erally to differ in the more elevated and comi^ressed body, shorter, 

 deeper head, and brownish or brassy rather than silvery coloration. 

 This represents the general tendency of ^^var. inacrolepidotum" ', but 

 specimens of '•'■ duquesnei ^^ can be found which will match the average 

 macrolepidotmn in each of these respects. The form which I have iden- 

 tified with Professor Cope's lachrijmaJe is to some extent intermediate, 

 but has the additional peculiarity of smaller scales. In this respect, 

 however, occasional individuals, both of duqriesnei 2i\iA of mactolepidotum, 

 can be lound which approach it. 



The form inhabiting the waters of the eastern and uorthern parts of the 

 United States is the variety macrolepidotmn. It is sold commonly as a food-
