Description
From Schmidly & Bradley (2016): "A small, fat-tailed mouse with pinkish cinnamon or grayish buff upperparts and pure white underparts; usually a conspicuous white or grayish tuft at anterior base of ear; nose, cheeks, and sides white; tail sparsely haired, >30% of total length, 2–2.5 times as long as hind foot and distinctly bicolor, dark above and white below. Similar to O. leucogaster but smaller, with relatively longer tail and smaller teeth. Juveniles similar to adults but upperparts bluish gray."
