The incisors are of moderate length, rather weak, narrow, compressed, and
curved inwards. In the upper jaw the first three molars are largest, the fourth
a little smaller; in the lower jaw the molars are alike. The molars have
rounded cutting edges.
Nose and head, of moderate size; sacs or pouches opening on the cheeks back
of the mouth; fore feet, rather short, furnished with four toes and the rudiment
of a thumb, covered by a blunt nail; hind legs very long, terminated by four
toes on each foot; toes, each with a distinct metatarsus tail, very long;
mammae, four--two abdominal and two pectoral.
Habits, semi-nocturnal; food, seeds, roots, and grasses.
There is only one species belonging to this genus known. The generic name
is derived from [dipous], two footed, and [mus], a mouse.
