Abstract
Between 1918 and 1920 Frank Collins Baker made a survey of the mollusks in the Big Virmilion River in east-central Illinois (Baker, 1922). His study was made largely in the Salt Fork of that river. He collected from 30 stations located from the headwaters north of Urbana to the junction of the Salt Fork with the Middle Fork just west of Danville.
