serrae and posterior process of the clei thrum, as well as some similarity 

 in color pattern suggest a remote relationship with typical Noturus 

 hildebrandi. Otherwise the elongate body form and small head indicate 

 some relationship to members of the elegans group. 



Etymology. — The name albater (Latin), albus (white) and ater 

 (black), meaning white and black, refers to the contrasting light areas 

 of the caudal fin and the dark saddles. 



Ecological considerations. — Records are from clear or normally 

 clear, moderate or large size streams, having a bottom of sand, gravel, 

 rubble, and large rock. The species lives in moderate to swift current, 

 primarily on the shallower riffles. Noturus albater has been taken in 

 collections with Noturus exilis, N. flavater, and N. miurus.
