Head and body length of the type specimen is 195 mm, and tale length is 110 mm. The pelage is soft, close, and velvety. The upper parts are uniformly gray, and the underparts are paler, but there is no sharply defined line of demarcation.
Most individual hairs are slaty gray on the basal part and washed with buffy white on the tip.
The sides of the muzzle are almost black, the ears are grayish, and the feet are dark gray as far as the digits, which are whitish or flesh-colored. The thinly haired tail is white except for the upper basal part, which is brownish. Celaenomys has a shrewlike body form and at a glance could be mistaken for Rhynchomys, but it is distinguished from that genus by its larger teeth and shorter muzzle. The incisors, like those of Rhynchomys, project forward, but they are larger and more powerful. The eyes are small, and the ears are short.
