feet, playing among fir-trees laden with snow wreaths. On the west
side of India they are not found to the north of 14° N. latitude.
On the east they extend into Arakan, and to Borneo and Java,
but not apparently into Siam or Cambodja. Along the eastern
extension of the Himalayas they again occur in East Thibet ; a
remarkable species with a large upturned nose {S. roxellana)
having been discovered by P^re David at Moupin (about Lat.
32° N.) in the highest forests, where the winters are severe and
last for several months, and where the vegetation, and the other
forms of animal life, are wholly those of the Palsearctic region.
It is very curious that this species should somewhat resemble
the young state of the proboscis monkey (S. nasalis), which in-
habits one of the most uniform, damp, and hot climates on the
globe—the river-swamps of Borneo.
Colobus, the African genus (11 species), is very closely allied
to the preceding, differing chiefly in the thumb being absent or
rudimentary. They are confined to the tropical regions—Abys-
sinia on the east, and from the Gambia to Angola and the island
of Fernando Po, on the west.

This family comprehends all the monkeys with cheek pouches,
and the baboons. Some of these have very long tails, some none ;
some are dog-faced, others tolerably round-faced ; but there are
so many transitions from one to the other, and such a general
agreement in structure, that they are now considered to form a
very natural family. Their range is more extensive than any
other family of Quadrumana, since they not only occur in every
part of the Ethiopian and Oriental regions, but enter the Palse-
arctic region in the east and west, and the Australian region as
far as the islands of Timor and Batchian. The African genera
