A DESCRIPTIVE LIST OF THE FISHES OF BIG 



JELLOWAY CREEK AND TRIBUTARIES, 



KNOX COUNTY, OHIO. 



By J. B. Parker, E. B. Williamson and 



R. C. OSBURN. 



Big Jelloway Creek is located in the northeastern 

 part of Knox County, Ohio, and is a part of the Mus- 

 kingum S3'stern. It is about twenty miles in length,

 about one hundred square miles, is hilly and abounds 

 in clear, cold springs. Owing to this fact, it is only in 

 seasons of long continued drought that the water in 

 the streams shows any appearance of stagnation. The 

 removal of the forests has rendered these streams 

 subject to violent and destructive freshets, which con- 

 tinually shift the banks and bottoms of the streams. 



Unfortunatel3% the time chosen for the investigation 

 was most unfavorable for the best results. Unusual 

 changes had been wrought in the general character of 

 the streams by the unusually high floods of the pre- 

 ceding months. The streams were filled with roots, 

 drift wood and rubbish of all sorts ; new channels and 

 ripples had been formed, and the old feeding and spawn- 

 ing places of the fishes were changed or gone. Then,
