of _P.
cephalopterus_. So striking was its whiteness that it might have been
conjectured to be an Albino, but for the circumstance that its eyes
and face were black. An old writer of the seventeenth century, Knox,
says of the monkeys of Ceylon (where he was captive for some time)
that there are some "milk-white in body and face, but of this sort
there is not such plenty."--_Tennent's 'Natural History of Ceylon,'
page 8_.

NOTE.--Since the above was in type I have found in the List of Animals
in the Zoological Society's Gardens, a species entered as
_Semnopithecus leucoprymnus_, the Purple-faced Monkey from
Ceylon--see P.Z.S.

PAPIONINAE.

This sub-family comprises the true baboons of Africa and the
monkey-like baboons of India. They have the stomach simple, and
cheek-pouches are always present. According to Cuvier they possess,
like the last family, a fifth tubercle on their last molars. They
produce early, but are not completely adult for four or five years;
the period of gestation is seven months.

The third sub-family of _Simiadae_ consists of the genera
_Cercopithicus_, _Macacus_, and _Cynocephalus_, as generally
accepted by modern zoologists, but Jerdon seems to have followed
Ogilby in his classification, which merges the long-tailed Macaques
into _Cercopithecus_, and substituting _Papio_ for the others.

_GENUS INUUS_.

Cuvier applies this term to the Magots or rudimentary-tailed
Macaques. The monkeys of this genus are more compactly built than
those of the last. They are also less herbivorous in their diet,
eating frogs, lizards, crabs and insects, as well as vegetables and
fruit. Their callosities and cheek-pouches are large, and they have
a sac which communicates with the larynx under the thyroid cartilage,
which fills with air when they cry out.

Some naturalists of the day, however, place all under the generic
name Macacus.

NO. 17. INUUS _vel_ MACACUS SILENUS.
_The Lion Monkey_ (_Jerdon's No. 6_).

NATIVE NAMES.--_Nil bandar_, Bengali; _Shia bandar_, Hindi; _Nella
manthi_, Malabari.

HABITAT.--The Western Ghats of India from North Lat. 14 degrees to
the extreme south, but most abundant in Cochin and Travancore
(_Jerdon_), also Ceylon (_Cuvier_ and _Horsfield_), though
not confirmed by Emerson Tennent, who states that the _silenus_ is
not found in the island except as introduced by Arab horse-dealers
occasionally, and that it certainly is not indigenous. Blyth was also
assured by Dr. T
