A total of 29 male specimens of Mustela killed by traffic accident on the road in Kagawa prefecture were identified by the relationship between head and body length (HBL) and tail length (TL), or hind foot length (HFL) and TL. However, the tail ratio (the proportion of TL to HBL), which is one of the method to distinguish between both species so far, is not adequate for the identification, because there is no difference between both the ratios (46.8% to 59.0% in M. sibirica coreana; 41.3% to 47.1% in M. itatsi). In addition, there seems to be no differences between both altitude distributions (5 m to 110 m in altitude in M. s. coreana; 5 m to 210 m in altitude in M. itatsi), according to the 29 specimens collected in this study.
