Abstract

Praemancalla wetmorei is described from the late Miocene of Orange County, California, with humerus and ulna as holotype and paratype, and radius, carpometacarpus, and coracoid referred. The species, although less specialized as a flightless diver than the geologically younger genus Mancalla, appears to be more advanced then Praemancalla lagunensis, which is believed to be derived from slightly older deposits.
