Subfamily Perognathinae Coues, 1875 . Proc. Acad. Nat. Sci. Philadelphia, 27:277.

COMMENTS: Subfamily name emended by Wood (1935); originally given by Coues as Perognathidinae. Wood (1935:89), Hafner (1978), and Hall (1981) included Microdipodops in the subfamily, a course not followed by Hafner and Hafner (1983), Wahlert (1985), and Ryan (1989a).
