the singing monkey , and the ventriloquist; by the natives it is called ouapoussa, 
or ouappo. 
The Death’s-head Monkey ( Chrysothrix , or Callithrix scienreus ,) is black, 
with a tinge of gray; its ears 
and face are white, and the 
mouth and nose a blue-black. 
Its tail is disproportionately 
long, and when the monkey is 
at rest he generally circles it 
about his middle so that he 
looks as if framed in a hoop 
of dead evergreens. 
The Brazilian Titi (Cal¬ 
lithrix per sonata, or sciurea ,) 
is named by naturalists from 
its beautiful hair, which is 
white on the ears, gray on the 
under parts, black at the ex¬ 
tremity of the tail, golden on 
the legs and light olive on 
the body. The titi is small 
in size, exceedingly active 
and affectionate, and always bearded saki. 
wears an innocent, pleading 
expression, which is heightened by its ready use of its tear-glands; its brown 
eyes generally have that ap¬ 
pearance of suppressed tears 
which is always so pathetic. 
Its most marked peculiarity, 
however, is its resemblance to 
the deaf, through its unflag¬ 
ging interest in watching the 
lips of any one who is talk¬ 
ing. Its tail is not prehen¬ 
sile, but is flexible without 
being muscular. The titi , from 
its activity, has been called the 
squirrel monkey , and it may 
not be unserviceable to men¬ 
tion that it is sometimes called 
the saimara , and sometimes 
the tee-tee. 
The Cuxio, Black Cuxio, 
Bearded Cuxio, or Saki (Pi- 
thecia , or Brachyurus satanas ), is 
cowled and heavily whiskered 
and bearded in black, and is 
-vainer of its natural ornament than even the Diana monkey. It is solitary in its 
iabits, or at most lives only with its immediate family. It is quite fierce and 
BLACK HOWLER.
