Tctalunis aniritilla Evermann & Kendall 



This interesting catfish was originally described from the 

 Atchafalaya River, but has since been seen by us in the Ohio at 

 Louisville. It does not appear to be a very common species, not 

 more than thirty examples having as yet been noted. It is, how-

 prized equally with the blue and channel cats. Its spawning time 

 in Louisiana is in April and May.
