Benthic Testacida from sediments of Lake Washington were studied. The Testacida were extracted using standard foraminiferologic techniques. The determined taxa were photographed using scanning electron microscopy. Twenty-one taxa were found. The majority were cosmopolitan and the most abundant were Difflugia pyriformis and Centropyxis compressa. The Testacida guild was similar to that previously studied in other American and European lakes. However, the type and size of the species were different from those found in soil and mosses.
