Oryzomys nelsoni Merriam 1898

Oryzomys nelsoni Merriam 1898, Proc. Biol. Soc. Wash., 12: 15.

Type Locality: México, Nayarit State, María Madre Isl.

Vernacular Names: Nelson's Oryzomys.

Distribution: Known only from the type locality.

Conservation: IUCN – Extinct; known only by the 4 specimens of the type series and presumed to be extinct (see Wilson, 1991).

Discussion: Allied to O. couesi, under which Hershkovitz (1971) listed it as a subspecies. Unquestionably a species distinct from mainland O. couesi and O. palustris as others have recognized (Goldman, 1918; Hall, 1981). See Alvarez-Castañeda and Méndez (2003, Mammalian Species, 735).
