22. Agosia nubila (Girard). 
Examples of this species from the Yaquina, Siuslaw, and Coquille rivers appear to agree in having 
the barbels very small or frequently absent from one or both sides, while those from the Umpqua and 
Willamette have them always present and well developed. In large males the pectoral fins are often 
very long, while small tubercles are present on the head and upper parts of body. 
The species was not found in the streams south of the Coquille.
