The Perote mouse is the size of a small rat, with a total length of , including a hairy tail that, at , is typically longer than the animal's body. The mouse is tawny-ochre in colour, with creamy white underparts. The middle of the back is duskier than the rest of the animal, and the sides of head are grey.
