ECOLOGICAL TABLE— concluded 



ALL ILLINOIS SPECIES WITH AT LEAST TEN AVAILABLE RECORDS EACH 



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 faunae of the surrounding territories, 

 southeastern species preponderating over southwestern, north- 

 eastern over northwestern, eastern over western, and southern 

 over northern.
