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.
