Morphological discrimination of C. rufocanus and Eothenomys regulus and their geographic distributions in the former USSR, NE China , and Korea assessed by Kaneko (1990) . Variation in morphology of upper third molar in context of systematic, age, and seasonal significance was reported by Abe (1982) . Chromosomal data suggest the need to re-evaluate the specific status of montanus and bedfordiae (see Kashiwabara and Onoyama, 1988 ).
