Hist., ser. 8, 20:198 . TYPE LOCALITY: Taiwan , Mt Arizan, 8000 ft . DISTRIBUTION: Endemic to mountains of Taiwan . COMMENTS: Either listed as a species ( Ellerman, 1941 ), a subspecies of N. niviventer ( Ellerman and Morrison-Scott, 1951 ; Wang and Zheng, 1981 ), or included in N. confucianus ( Musser, 1981b ) . It is a distinctive insular form that in morphology resembles mainland N. confucianus , but differs sufficiently that it should be treated as a species until relationships can be assessed by systematic revision of the genus.
