Littel is known about the fossil birds of the Nojiri-ko Formation except for the bean goose (Anser fabalis SWINHOE; NAKAMURA, 1975). This paper deals with an incomplete left humerus and a complete left ulna, from two other species. The humerus was obtained from the Middle Nojiri-ko Formation, but the precise stratigraphic position of the ulna is unknown. These materials are compared with humeri of the genus Phalacrocorax (order Pelicaniformes), and ulnae of the genus Phasianus (order Galiformes) occurring in Japan. The humerus from the Nojiri-ko Formation is somewhat smaller than that of the common river cormorant (Phalacrocorax carbo), but it is assigned to P. carbo (LINNAEUS). The ulna is larger than that of the recent copper pheasant (Phasianus soemmerringii TEMMINCK), but it is assigned to P. soemmerringii TEMMINCK.
