Hist., ser. 9, 7:246 . TYPE LOCALITY: Indonesia , NE Sulawesi , Minahassa, Gunung Masarang, 2000 ft . DISTRIBUTION: NE Sulawesi only, from vicinity of Teluk Kuandang ( 0°50'N , 122°52'E ) east to Gunung Klabat ( 1°28'N , 125°02'E ). SYNONYMS: tondanus . COMMENTS: Although marmosurus has been listed as a subspecies of R. xanthurus ( Ellerman, 1941 ; Laurie and Hill, 1954 ), most researchers besides Thomas have recognized its specific uniqueness ( Misonne, 1969 ; Musser, 1971c , 1984; Musser and Holden, 1991 ; Sody, 1941 ; Tate, 1936). Furthermore, the two are sympatric in NE Sulawesi ( Musser, 1971c ). Sody (1941) questionably included marmosurus in Taeromys , but it is a member of the Rattus xanthurus group. Musser (1971e) explained why tondanus is a synonym.
