TYPE SPECIES: Bullimus bagobus Mearns, 1905 .

COMMENTS: Although described as a distinctive genus by Mearns, Bullimus has been treated as a subgenus of Rattus in most taxonomic works (e.g., Ellerman, 1941; Misonne, 1969; Simpson, 1945) until generically reinstated by Musser (1982c) and Musser and Newcomb (1983) and rediagnosed by Musser and Heaney (1992), who also documented taxonomic history and past associations with other murine genera. Belongs to the group of Philippine New Endemics, but its closest phylogenetic relative has yet to be resolved (Musser and Heaney, 1992). Genus needs critical systematic revision, number of actual species is uncertain, those listed below are provisional (Musser and Heaney, 1992; Musser and Newcomb, 1983).
