28. Notropis umbratilis atripes (Jordan), Blackfin. 

 Abundant in the Embarras and Kaskaskia Rivers and in 



the larger creeks connected with these rivers. 



29. Ericymba.buccata Cope, Silver-mouthed Minnow. 

 Abundant and very generally distributed in the rivers 



and all creeks but the smallest ones of both systems- 

 creeks. The adults prefer larger streams. 



30. Phenacobius mirabilus (Girard), Sucker-mouthed Min- 

 now. 



Not common but frequently taken in the rivers and large 

 creeks of both systems. 



31. Hybopsis dissimilis (Kirtland), Spotted Shiner. - 



Very rare. Recorded for the region by Forbes and Rich- 

 ardson. None taken by the writer. 



32. Hybopsis amblops (Rafinesque), Big-eyed Chub. 

 Quite common in the Embarras and Kaskaskia Rivers 



and in their larger tributaries. Avoids small creeks. 



33. Hybopsis storerianus (Kirtland). Storer's Chub. 

 Abundant in the Embarras River, where it is often taken 



''' on worm-baited hooks. Not found in tributaries of 



this stream except near their mouths. 



34. Hybopsis kentuckiensis (Rafinesque), River Chub. 

 Abundant in the Kaskaskia system. Only two have been 



found by the writer in the Embarras system. These 

 came from Polecat Creek. Forbes and Richardson re- 

 cord it for the Embarras River in Douglas Co. 

 33. Ictalurus anguilla Evermann and Kendall, Eel Cat. 



A catfish caught by hook in the Embarras River on July 

 1, 1912, by Mr. C. P. Lantz, answers the description 

 of this species. 



35. Ictalurus punctatus (Rafinesque), Channel Cat. 

 Abundant in the Embarras River, and found in some 



numbers in parts of its larger tributaries. 



37. Ameiurus natalis (Le Sueur), Yellow Bullhead. 

 Frequently taken by hook from deep holes in the rivers 



and from similar places in creeks. Large numbers of 

 the very young of this species are often found in small 

 creeks. The adults prefer larger streams. 



38. Ameiurus melas (Rafinesque), Black Bullhead. 

 Common especially in large streams. Distribution sim- 

 ilar to that of natalis. The two species appear to be 

 closely associated. 



39. Laptops olivaris (Rafinesque), Mud Cat. 



Found in small numbers in the Embarras and Kaskas- 

 kia Rivers. 



40. Schilbeodes gyrinus (]\Iitchill), Tadpole Cat.
