Oryzomys rostratus Merriam, 1901 . Proc. Washington Acad. Sci., 3:293.

TYPE LOCALITY: Mexico, Puebla, Metlaltoyuca .

DISTRIBUTION: Deciduous and evergreen tropical forests from central Tamaulipas to Oaxaca and Yucatan Peninsula, Mexico, through Guatemala, El Salvador, and Honduras, to S Nicaragua.

SYNONYMS: carrorum, megadon, salvadorensis, yucatanensis .

COMMENTS: Considered a subspecies of O. melanotis ( Hall, 1981; Hooper, 1953). Engstrom (1984) effectively argued the specific distinctiveness of O. rostratus (also see account of O. melanotis ). Distributional records in Nicaragua reviewed, as O. melanotis megadon , by Jones and Engstrom (1986). Homogeneity of populations assigned to O. rostratus warrants additional study.
