The Coati-Mundi, (pronounced coy-ty mon-day), is for its size one of the best exhibition animals that can be found outside of the Primate House. It is closely related to our raccoon, but is far more showy and interesting. It has a very lively and industrious disposition, is a good climber, and from dawn until dark is almost constantly on the move. Although it is a carnivorous animal, and provided with powerful canine teeth, it is not naturally quarrelsome, but on the contrary is quite gregarious in its habits. The genus _Nasua_ inhabits Mexico, Central and South America. We have two species, the Red Coati-Mondi, (_Nasua rufa_), and the White-Nosed, (_N. narica_). The Raccoon Dog, of Japan, (_Nyctereutes procyonoides_), is to all outward appearances a raccoon, but its feet are digitigrade, not plantigrade, and it is a true dog. The American Badger, (_Taxidea americana_), is represented by a fine, large and very light-colored specimen that was presented by President Roosevelt. The European Badger, (_Meles taxus_), is shown near by. Our collection of Rodents contains the following important and representative species of squirrels: North American.

Squirrel No collection of Rodents is worthy of acceptance by the public without a fair representation of Porcupines. The most wonderful species is the African Porcupine, (_Hystrix cristata_), which when disturbed erects a threatening array of enormously-long, shining black-and-white quills that are a wonder to behold. The lofty white crest of this animal is one of its most conspicuous features.
