This North American Rodent is famous for its ability to make riving leaps of from eight to ten feet at a bound, although its size is only about that of the Common Mouse. The picture rim idea of its jumping ability, fjaculus hudsonius.) hind legs are about three times the size of the fore- legs; the tail is of proportionate length, but its extremity usually shows a tuft, the hair of which is arranged in a double row. On the other hand, the head of the Dipodid;e differs materially from that of the Kangaroos. It is very thick ami adorned with mustaches, which, pro- v portionately to the size of the animal, are the longest among all mam- mals, for they are often as long as the body. The eyes are large but have an expression that is vivid and prepo- ing to an extent equaled by few other nocturnal animals. The ears are erect and spoon-shaped, and of varying length in different species. In some the ears equal the head in length, in others they are only a third as long, but they are all suf- ficiently large to show that hearing is a well- developed sense with these animals. The neck is thick and immobile, the trunk slender, and the fur is close, soft and of a sandy hue. General The Jerboas principally inhabit Traits of the Africa and Asia; some species, how- Jerboas. ever, reach over into southern Eu- rope, and one species or sub-family is indigenous fo North America. They all inhabit dry, open fields, grassy plains or arid deserts of sand. On clayey or sandy soil, in low-lying situations; sometimes, but rarely, on hills, or amid dense bushes border- ing on
