Notiosorex Coues, 1877 . Bull. U.S. Geol. Geogr. Surv. Terr., 3:646.

TYPE SPECIES: Sorex (Notiosorex) crawfordi Coues, 1877 .

COMMENTS: Tribe Neomyini; see Repenning (1967:45). Reumer (1984:14) created a new tribe Notiosoricini to include Notiosorex, but George (1986: 160) could find no evidence to support this separation. Hall (1981: 65) included also Megasorex gigas, but Repenning (1967:56), Armstrong and Jones (1972), and George (1986) considered Megasorex a distinct genus. Notiosorex (Xenosorex) phillipsii is a synonym of Cryptotis mexicana; see Choate (1969). Lindsay and Jacobs (1985) described an extinct species from Pliocene sediments of Chihuahua, Mexico.
