The incisor teeth are broad, flattened in front, and pale yellow with a white tip. The eyes are small, and the ears are rather small and naked. The forefeet are normal for a murid, but the hind feet are elongated, suggesting the possibility of leaping habits. The three center toes of the hind feet are considerably larger than the others. There are five sole pads on the front feet and six on the hind feet.
Females have four mammae.
