The Encyclopedia Americana (1920)/Proboscis or Nose Monkey

PROBOSCIS or NOSE MONKEY, a rare Bornean monkey (Nasalis larvatus), called “Kahau” by the natives, and characterized by a greatly elongated nose, giving a peculiarly ludicrous appearance to the face. The general body-color is a sandy red; the tail is dark above, but light yellow beneath. These monkeys are arboreal in habits, and appear to frequent the neighborhood of streams and rivers, congregating in troops. They are closely allied to the apes of the genus Semnopithecus.
