The literature on the s])ecies shows that it has a j^ood many enemies in the 

 form of ])arasites. kiley ('18, p. 3) found about 6o^c of these bass infested with 

 cestofles and other wi>rms, in Bass Lake, Mimiesota. Kunfji readily attack their 

 «-'KKs (Hccman, '24, \\. 103) and constitute an important obstacle to hatching them 

 in ponds.
