Discussion: Formerly in Microsorex , which is a synonym of subgenus Otisorex , according to George (1988). Includes thompsoni since Diersing (1980 b), but D. T. Stewart (in litt.) suggested that it may be a distinct species, as previously postulated by Long (1972 b). Reviewed by Long (1974, Mammalian Species No. 33) and Junge and Hoffmann (1981). Sorex browni George, 1988 [replacement name for minutus (Brown, 1908) , not Linnaeus, 1766] is the name for a Wisconsinan shrew related, if not conspecific, with S. hoyi . The name montanus used by Long (in Wilson and Ruff, 1999) for the Colorado and Wyoming population is a secondary homonym of S. montanus Kelaart (now Suncus montanus ), and may therefore persist ( Hutterer and Zaitsev, 2004). Karyotype insufficently known; Meylan (1968) provisionally identified 2n = 62, FN = 72.
