7i) 



were, as far as could be determined in a hasty examination, chiefly 

 those of trees and weeds. Elm seeds, ragweed seeds, and the seeds 

 of Polygonum were noted. The Mollusca were partly thin-shelled- 

 clams with an occasional Sph.Brium, and partly snails, such as Physa 

 and Lioplax. All the matter was apparently gathered from the 

 bottom. No trace of crustacean or insect food could be detected.

Quill-back Buffalo {Ictiobus buhalus, Raf.). 



Not observed in any of the bottom-land pools outside the levee, 

 excepting Broad Lake. The young from B to 5 inches long were- 

 rather common inside the levee. The only large examples seen 

 were taken from the river, where they seemed to be moderately 

 common. The young are easily distinguished from the young of 

 /. cijprineUa by their small, inferior mouth, compressed body, 

 and pale colors, — especially of the pectoral and ventral fins.

Mongrel Buffalo {Ictiobus urus, Ag.). 



In my field notes I have recorded the young of this fish as

 not seen elsewhere. Adults were common in the river, and were 

 sometimes seen of large size. One was noted August 6 which, 

 weighed twenty and a half pounds.
