one hundred and sixty localities, thirty-one of which are south of the 
Sangamon and eight of them from the non-glaciated area of the Cairo 
district, but only one of the entire number is within the lower glacia- 
tion, and thatison the upper Kaskaskia, just across the limiting mo- 
raine. The map for Notropis cornutus shows one hundred and sixty- 
one localities from which collections of this species were made, ninety 
of them below the Sangamon and twenty-nine in the Cairo district, 
but only three are in the southern glaciation. Other species testify- 
ing to the same effect will be found in the following list of fishes ab- 
sent from this characteristic southern Illinois district.
