mentions one which he shot at a height of fully one hundred and fifty feet above 
the ground. Writing of one of the Chilian species, M. Germain states that “these 
monkeys usually have a permanent sleeping-place, whence they issue every morning 
to explore the neighbouring trees; the eggs and young of birds, insects, tender shoots, 
and, above all, fruits forming their chief food. I have never seen them,” continues 
M. Germain, “ on the ground, and I believe they never leave the tree-tops; while I 
have observed that they have particular routes in their journeys through the forest. 
The troops in which they live are not numerous, comprising from eight to a dozen 
individuals, under the leadership of an old and experienced male. When they 
arrive at the locality, where the fruits of which they are in search are to be found, 
each endeavours to seize as speedily as possible the best upon which it can lay its 
hands; but, both on its arrival and during its return, the band is far from being in 
disorder. In dangerous places, where a kind of gymnastic performance has to be 
undertaken, the troop passes in single file; each one not risking the jump till the 
one in advance has safely passed, and then seizing firmly the same boughs and 
jumping in just the same manner as the latter. I have sometimes seen them at 
a height of about one hundred and fifty feet from the ground suspend themselves by 
the tail from a branch, then balance themselves, with all four limbs stretched out, 
then, all of a sudden, let themselves go, and falling for a distance of some twenty or 
thirty feet, seize hold of another bough by the tail. In such falls the outstretched 
arms seem only ready in case of accident, for there is never any question of 
maladroitness.” 
Together with the spider-monkeys, the sapajous are the most docile and the 
most readily taught of all the American monkeys, and since they bear confinement 
and the European climate well, they are the most common of the monkeys carried 
about by the peripatetic organ-grinder. 
The White-Cheeked Sapajou ( Cebus lunatus). 
The white-cheeked sapajou, of which a representation is given in the middle 
upper figure of the woodcut on page 150, is an inhabitant of Brazil. According 
to Dr. Gray’s description, this animal is characterised by the length of the hair 
on the head, which is directed backwards, while that round the jaw is longer, 
and curved so as to form a kind of crest on each eyebrow. On the cheeks the 
hair is short and flattened down. The fur of the body and head is long, soft, 
and silky, its general colour being blackish, but that on the cheeks and temples is 
yellowish-white. It is this light hair on the cheeks that gives its distinctive 
name to the species. The head is relatively large. 
The Brown Sapajou (Cebus fatuellus). 
In Guiana the sapajous are represented by a species commonly known as the 
brown sapajou, which presents a certain variation due either to differences of age, 
or to individual peculiarity, in regard to the form of the hair on the head, which 
has led to the supposition that there were two distinct species. In one of these 
forms, as represented in the upper right-hand figure of the woodcut on p. 150, the
