The list is undoubtedly more complete for species represented 

 in the streams by small individuals than for those with large ones, 

 since methods primarily for collecting large fish were little used, 

 most of the collecting being done with minnow seines. 



1. Hypentelium nigricans (LeSueur), Hog Sucker. — Apparently 

 scarce in the river. A small one taken at Station 7. 



2. Catostomus commersonii (Lacepede) , Common Sucker. — Two 

 small ones under five inches long taken in Sycamore Creek, 

 Station 26. None of mature size were taken or noted, but Frank 

 Sawyer says that suckers (very probably this species) are abundant 

 in the river in early spring at their spawning time. 



3. Minytrema melanops (Rafinesque), Spotted Sucker. — One 

 small one, two inches long, taken in August, at Station 26. 



4. Moxostoma aureolum (LeSueur) , Common Red Horse. — One 

 young one, two inches long, taken at Station 7. 



5. Moxostoma duquesnei (LeSueur), Fine-scaled Red Horse. — 

 A young one two inches long caught at Station 26. 



6. Cyprinus carpio Linnaeus, Carp. — A small one nearly four 

 inches long of the scaled variety was taken in Sycamore Creek, 

 Station 26. Frank Sawyer says carp are abundant in the river 

 in the spring and follow the suckers at their spawning time and 

 probably eat the spawn. 



7. Campostoma anomalum (Rafinesque), Stone Roller. — One 

 taken in Sycamore Creek in August, 19 19. 



8. Pimephales notatus (Rafinesque), Blunt-nosed Minnow. — 

 Abundant and generally distributed in the river but most common 

 in the shallower water and where the bottom is stony (Station 30) 

 or sandy (Station 12) or where there is much aquatic vegetation 

 (Station 7). Not many places with these especially favorable 

 conditions for the species were found in the part of the river 

 examined. 



The minnow breeds in the Galien River. Egg patches were 

 found in June on the flat undersides of objects on the bottom;
