Description
From Wilson et al. (2016): "Male White-eared Pocket Mice are significantly larger than females. Pelage is soft, fine, and full with no hint of spines orstiff bristles; posterior one-half of sole of hindfoot has sparse covering of short hairs; and tail is short and not tufted. Unlike most other silky pocket mice, the White-eared Pocket Mouse has lobed antitragus of ear pinna, and tail is slightly crested for distal one-third (with dark hairs). The White-eared Pocket Mouse is medium-sized to large-sized for the genus but smaller than its close relatives, the Great Basin Pocket Mouse [Perognathus mollipilosus] and the Columbia Plateau Pocket Mouse (P. parvus). Hairs on inner surface of ear pinna are white or yellowish. Dorsal pelage is yellowish brown and heavily blackish lined, dorsal hairs are plumbeous at their bases for 75 % of their length, lateral line usually is faintly expressed, and under parts are white. Tail is the same length or slightly longer than head-body length and bicolored."
