Eocene Foraminifera from Cowlitz River, Washington, are described and figured. The collection of 65 samples from 200 feet of strata contained 107 species and subspecies. Twenty-five species and 8 subspecies are new. The assemblage constitutes but one faunule, which is referred to in introducing the term Saracenaria mackini zonule for the strata investigated. An ecologic analysis of the faunule indicates that it possibly lived off a tropical coast in warm marine waters at the outer margin of the neritic zone, down to and perhaps into the upper bathyal zone. The Cowlitz River beds are Eocene; they are in part correlative with the Coaledo formation of Oregon, and the Tejon and Poway formations of California. The Cook Mountain formation of the Gulf Coast contains several species in common with the Cowlitz.
