Forbes found the stomach of this fish full of dirt, with fragments of 

 endogenous vegetation, confervoid algai, and many diatoms. The mud 

 made up about eighty per cent, of the food. About July 1 I found, at 

 Logansport and Wii amac, many females of this species laden with eggs, 

 while many males had the head covered with tubercles. The spawn 

 must be deposited about this time.

Body rather slencfer ; mouth somewhat inferior. Teeth 1, 4-4, 0. Man- 

 dible, interopercle, and suborbitals with conspicuous mucous cavities.
