R . norvegicus norvegicus : Kuroda, 1938 p.69 ; Won, 1968 p.173 . Range: The brown rat is commensal everywhere people live on the Korean Peninsula and associated islands ( Fig. 124 ). FIGURE 124. Range map of Rattus norvegicus in Korea. Remarks: Corbet (1978) noted that the common rat, Rattus norvegicus , had an extensive distribution in the world and recognized two subspecies ( R . norvegicus norvegicus in the western Palearctic and R . norvegicus caraco in eastern Asia). Won (1967) reported two subspecies of R . norvegicus in Korea ( R . n . norvegicus in most of the peninsula and R . n . caraco in the extreme northern part). Nevertheless, Jones and Johnson (1965) suggested that only one subspecies; R . n . caraco , inhabited the entire peninsula. Kral (1971) reported that the two subspecies of common rats ( R . n . norvegicus ; R . n. caraco ) in Russia had identical karyotypes (seven metacentric, nine telocentric, four subtelocentric autosome pairs); the same karyotype was reported by Kang and Kim (1963) for R . n . norvegicus in Korea . On the basis of C-banding patterns and morphometric variation, Koh (1992) suggested that a single subspecies inhabited Korea , namely R . n . caraco . The subspecies on Ulleung Island was classified as R. n. longicaudus by Mori (1937) but was erroneously identified as a subspecies of R . norvegicus ( Jones & Johnson 1965 ) . The subspecies on Ulleung Island is Rattus rattus tanezumi .
