Extensive holdings of Pristiloma snails in the Oregon State Arthropod Collection were evaluated and reidentified as necessary. The study confirmed the distinctness of Pristiloma crateris from other species and delineated a range in Pacific Northwest National Forests, primarily along the western and eastern slopes of the Cascade Range in Oregon.
