THE PIKE PERCHES. 13 



The largesf and most important form is Stizostedion vitrcum, generally 

 referred to by recent writers ui)on fishes as the Wall-eyed Pike. This 

 well-known species is found in nearly all the water systems frecjuented 

 by S. canadcnse, and in many others, its geographical range being much 

 more extended. It inhabits the Great Lakes and their confluents,* and oc- 

 curs in most of the little lakes of Western New York, — Cayuga, Seneca, 

 Chatauqua, Oneida and many others. It ranges north to the fur countries, 

 and is doubtless widely distributed through British America. It is found 

 in the Susquehanna and the Juniata, in the Ohio River, and many of its 

 tributaries, in Western Virginia and North Carolina, in Kentucky, in Rock 

 Castle River and elsewhere in Tennessee, especially in the French Broad 

 and at least as far south as Memphis, in Georgia in the Oostanaula river 

 and it is said, in Arkansas. Its range to the south and southwest deserves 

 careful investigation. 



THE WALLEYE. S. VITREIJI. 



Jordan recognizes two subspecies oi Stizostedion vitrciiin — the typical form 

 S. vitrcuinvitreum, andasmaller, heavier bodied form which is bluer in color 

 and is generally known as the Blue Pike, S. vitrcum salmoneitin. This, he 

 states, is a local variety in Ohio and southward. It has been considered a 

 distinct species by many naturalists since the days of Rafinesque. 



The geographical range as well as the classification of the American 

 Pike-Perches, as the reader must have inferred from what has been said 

 about them in these pages, need to be studied much more exhaustively before 

 a satisfactory essay can be written upon them. Their habits are very im- 

 perfectly understood, and it will be necessary to refer to what is known of 

 their kindred in Europe, in order to give even a partial idea of their life- 

 history. 



In the Old World, as in the New, there are two well marked species, 



*A specimen was taken in April, 1S87, in the Connecticut river at Portland, as recorded by Professor Wil- 

 liam North Rice.
