Acad. Nat. Sci. Philadelphia , 1: 97 . Type Locality: USA , South Carolina , Charleston Co., vicinity of Charleston. Vernacular Names: Eastern Harvest Mouse . Synonyms: Reithrodontomys (Reithrodontomys) carolinensis (Audubon and Bachman 1842) ; Reithrodontomys (Reithrodontomys) dickinsoni Rhoads 1895 ; Reithrodontomys (Reithrodontomys) impiger Bangs 1898 ; Reithrodontomys (Reithrodontomys) lecontii (Audubon and Bachman 1842) ; Reithrodontomys (Reithrodontomys) merriami J. A. Allen 1895 ; Reithrodontomys (Reithrodontomys) virginianus A. H. Howell 1940 . Distribution: SE USA , from E Oklahoma and E Texas eastwards to the Atlantic seaboard, from S Maryland to peninsular Florida . Conservation: IUCN – Lower Risk (lc). Discussion: Subgenus Reithrodontomys , megalotis species group. The standard and banded karyotypes depart markedly from other species of the megalotis group, and substantial variation in fundamental numbers has been reported among populations ( Bradley et al, 1988 ; Carleton and Myers, 1979 ; Engstrom et al., 1981; Robbins and Baker, 1980 ). Genetically strongly divergent from six other species of the subgenus Reithrodontomys based on cytochrome b sequences ( Bell et al., 2001 ). Whitaker and Hamilton (1998) regarded the subspecies virginianus and humulis as broadly intergrading and synonymized the former; L. Choate and Jones (1998) mentioned possible westward expansion of R . h. merriami in Oklahoma . See Stalling (1997 , Mammalian Species, 565).
