COMMENTS: Subgenus Sorex . Youngman (1975) provided evidence that tundrensis is specifically distinct from arcticus . Palearctic populations formerly referred to arcticus were included in tundrensis by Junge et al. (1983). Hoffmann (1987) and van Zyll de Jong (1991b) discussed additional aspects of its taxonomy and distribution. Kozlovskii (1976) found irkutensis and sibiriensis to be karyotypically distinct; possibly two sibling species occur throughout the Palearctic range. Meylan and Hausser (1991) described a karyotype from Canada that is "identical" to some in Siberia.
