GENERAL SUMMARY 



The principal conclusions of this chapter may be thus sum- 

 marized: 



1. The 150 native species of Illinois fishes here recognized, 

 are so distributed within and without the state as to indicate an 

 unequal commingling of the f aunse of the surrounding territories, 

 southeastern species preponderating over southwestern, north- 

 eastern over northwestern, eastern over western, and southern 

 over northern.
