Up to the present time but very little has been known of the existence of the peculiarly American family Procyonidae in any deposits older than the very latest Quartenary. Leidy has described and figured an isolated last upper tooth, from the Loup Fork deposits of Nebraska, under the name of Leptarctus prirnus, which has been referred to this family. The Museum Expedition of last year into this region was successful in obtaining additional material, which we provisionally refer to Leidy's species.
