The Notropis cornutus is most generally known as the redfin; 
other names shared with other fishes are dace and shiner. It is 
one of the largest of its genus, reaching a length of five to eight 
inches, and is one of the most abundant wherever found. It is. 
often a companion of the common shiner (Abramis—N otemigonus— 
chrysoleucas). ‘The color is steel-blue above, but in the spring the 
males become conspicuous for their gay attire, red or rosy lower 
fins, and tuberculated head; it is allusion to these tubercles, remind- 
ing one or horns, that the name cornutus involves. It is frequently 
caught by the angler for small fishes.
