DRAINAGE OF THE MISSISSIPPI RIVER. * 
I.— THE MISSISSIPPI RIVER. 
Collections were made in this river at Muscatine and Davenport, the former 
locality affording by far the best results. There are many bayous at Muscatine, and 
the river there has generally a sandy bottom and many islands. The best fish market 
in Iowa is also located in that city. At Davenport there are fewer bayous, and the 
bottom of the river is more muddy and rocky. One day was spent at Davenport, and 
three days, at different times, at Muscatine. Mad Creek is a small stream flowing 
through Muscatine and emptying into the Mississippi. Few specimens were observed 
except near its mouth. The species enumerated in the following list are from the 
river at Muscatine unless otherwise expressly stated.
