Sorex milleri Jackson, 1947 . Proc. Biol. Soc. Washington, 60:131.

TYPE LOCALITY: "Madera Camp, altitude 8,000 feet, Carmen Mountains, Coahuila, Mexico " .

DISTRIBUTION: Restricted to the Sierra Madre Oriental of Coahuila and Nuevo Leon, Mexico.

COMMENTS: Subgenus Otisorex . Controversial opinions on the systematic status of milleri exist; Findley (1955a) regarded it as a morphologically distinct relict population allied to cinereus and accepted its specific status, as did Hall (1981) and Junge and Hoffmann (1981); while van Zyll de Jong and Kirkland (1989) suggested that milleri may not merit full specific status.
