warm water. The food in captivity includes hard clam, earth- 

 worms, and, occasionally, live killifish. 



A. N. Cheney refers to this species on page 245 of the 3d 

 Annual Report of the Commissioners of Fisheries, Game and Forest 

 of the State of New York. 



In Pennsylvania it is the commonest minnow in the Allegheny 

 and Susquehanna basins and is sufficiently common in the Dela- 

 ware. According to Prof. Cope it reaches 4 pounds in weight 

 and is a fair food fish. 



This species is more characteristic of the small streams and 

 clear ponds and it takes the hook very freely; but its proper 

 mission is to serve as bait for the larger and choicer fishes.
