with light golden color ; fins, reddish, narrowly margined with dusky- 

 black; dorsal, caudal and anal with dusky mottlings. McAtee and 

 Weed (Proc. Biol. Soc. Wash., Vol. XXVIII, 1915, p. 10) state that the 

 species is rare in river and canal. 



8. Moxostoma macrolepidotum (Le Sueur). 



Very abundant in canal in this region. Three examples ranged in 

 length from 238 to 355 mm. 



CvPRINIDiE. 



9. Cyprinus carpio (Linnfeus). 



Common in the canal. Two of the largest were 650 and 800 mm. in 

 length. This species is very tenacious of life if handled in such a manner 

 that the gills are not injured, but bleeds to death very quickly, even from 

 a slight abrasion. Carp seined from the canal were not returned to the 

 river but were saved by the seiners for food, the most of them to be 

 salted for winter use. Fish thus taken were carried in sacks in a wagon 

 during the day and in the evening were packed in a live car placed in 

 the bed of a small stream, some of them being above the water level. 

 The number that died under this treatment was surprisingly small. 



10. Carassius auratus (Linnseus). 



Not uncommon in the canal. Of eight examples examined, the largest, 

 300 mm. in length, was black and dull orange. One was a uniform 

 bright red, the others dusky silvery. 



11. Hybognathus nuchalis Agassiz. 

 Common in the canal, the largest being 106 mm. in length. 



12. Semotilus corporalis (Mitchill). 

 Common in Little Seneca and Tenmile Creeks. 



13. Semotilus atromaculatus (Mitchill). 



No examples were taken in the canal. Three, 93 to 163 mm. long, were 

 seined in a small rivulet near the canal. In Little Seneca and Tenmile 

 creeks, the species is abundant. Examples taken in June ranged in 

 length from 50 to 115 mm., and small examples taken in September were 

 40 to 45 mm. long. 



14. Notemigonus crysoleucas (Mitchill). 



Abundant in canal, especially at a point locally known as Buzzards 

 Hole; none taken in upper stretches of Seneca Creek. 



15. Pimephales notatus (Rafinesque). 

 Common in the canal ; abundant in Little Seneca and Tenmile creeks. 



16. Notropis procne (Cope). 

 Apparently rare in the canal. 



17. Notropis hudsonius amarus (Girard). 

 Abundant in the canal.
