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, 1988), Ryan (1989a), and Williams et al. (1993). Williams et al. (1993:121) provide a key to the genera. |
