Description
From Smolen (1981): "The body is cylindrical, slender, and modified for semi-fossorial life. Fur is soft and dense; ears, eyes, and tail are reduced; facial vibrissae are well developed; the mouth is small and the upper lips are closely appressed beneath the upper incisors. The feet have five plantar pads. Females bear two pairs of inguinal mammae (Miller, 1896; Bailey, 1900; Hall and Cockrum, 1953)."
From Best & Hunt (2020): "Woodland voles are small, and the tail is slightly longer than the hind feet. Eyes, ears, and mouth are small, and ears are hidden partially by fur. Pelage is thick and soft. Fur is dark reddish-brown dorsally, paler on the sides, and gray washed with brown ventrally. The tail is indistinctly bicolored."

From Best & Hunt (2020): "The woodland vole can be distinguished from the prairie vole [Microtus ochrogaster] by its shorter tail and from the southern bog lemming [Synaptomys cooperi]] by its lack of grooved incisors."
