Hist., ser. 7, 17:88 . TYPE LOCALITY: Japan , Ryukyu Isis, Amami-oshima Isl . DISTRIBUTION: Japan , Ryukyu Isis of Amami-oshima, Tokun-oshima, and Okinawa (known by modern specimens only in north, but by Quaternary fossils from farther south on island, and from Miyako Isl about 250 km S W of Okinawa ) (see Kawamura, 1989 ). SYNONYMS: bowersii var. okinavensis . COMMENTS: Historical and incorrect allocation of legatus with Lenothrix and Rattus is reviewed by Kawamura (1989) . Phylogenetic relationship, discerned from molar occlusal patterns, close to Rattus and far from Lenothrix ; "phylogeny of this unique genus will be sufficiently understood, when the fossil murids from China , India and Southeast Asia will be investigated in detail" (Kawmura, 1989:110). Chromosomal data reviewed by Tsuchiya (1981) .
