readily recognized as distinguished from that of 
Sapajou or Brachyteles by the mode of articulation 
of the nasal bones with the intermaxillaries. In the 
Sapajous, no true articulation can be said to take 
place. 
In Bracliyteles and Lagotliri.x a broad, well-marked 
articulation takes place. The rami of the lower jaw 
are much broader than in either of the before-men- 
tioned genera, approaching in size and form those of 
the Howlers. Gray records as generic traits that they 
are “slow, gregarious, meek, and often walk on their 
hind legs.”

Humboldt’s Monkey. 
HUMBOLDT’S LAGOTHRIX [Lagothrix humboldtii) 
called, also, the Gray Capparo. — The Upper Amazon 
is the favorite abiding-place of this Monkey, which is 
one of the largest of the American species ; stout of 
limb, with a dense, black coat of fur, which reaches 
to the tip of his prehensile tail, and forms a deep, thick- 
set diadem around its head. Its fur is used e.\ten- 
sively in commerce. A fine series of specimens of 
this Monkey is in the American Museum. Central 
Park, N. Y., showing the male, female and several 
young in various stages of growth. It is an interest 
ing fact in this connection that so valuable a collec- 
tion of Monkeys is accessible to the student, d'his is 
the largest series of prepared specimens on this con- 
tinent, comprising equally numerous species in the 
two divisions of Old and New World. The types, 
and all the specimens gathered by Prince Ma.ximilian 
of Neuweid, are there, and a choice collection, also, 
from A^erreau.x’s, in Paris. The present species is a 
blackish-gray ; the hairs individually are dark gray, 
with very short black tips. The head, chest, belly, 
hands and tail are black. 'I’he hair on the belly is 
rather longer. The young are quite a uniform gray. 
This is the Gastrimargus olivaceus of Spi.x, Simia 
lagotricha of Humboldt, and L. capparo of Lesson. 
It inhabits Peru, mouth of the Orinoco, and Columbia. 
THE REDDISH CAPPARO [Lagothrix ii{fumatu8) is a 
large Moidcey found on the rivers Ycayali and Hual- 
laga, and over the whole valley of the Peruvian 
Amazons. It is very common in the forests of the 
low country, generally in pairs ; sometimes four or 
six pairs are seen occiqjying the same trees. The 
Mycetes suffer them to associate with them. These 
Monkeys are in great request for food, and, being very 
abundairt, are extensively used. Bates speaks of a 
large specimen of this genus that he sent to the 
British Museum, which measured twenty-seven inches 
in length, the tail being twenty-six more. A Black 
Howler measured twenty-eight inches. The skin of 
the face in these Monkeys resembles that of an old 
negro. The Tacuna Indians eat them, and it is cal- 
culated that the tribe of two hundred persons de- 
stroyed twelve hundred of them annually for food. 
In captivity, it is much like the Spider Monkey — 
grave and confiding. It is not hardy, and seldom 
survives removal from its haunts. 
The Eeddish Capparo is a dark reddish-gray. The 
hairs are reddish, with black tips. The head and 
hands are rather darker. The inside of the fore-arms, 
chest and belly, is black ; the groin, base of the tail 
and the sides, are redder. The hair on the chest and 
belly is abundant, long and rather rigid. It inhabits 
Brazil. 
Tribe III.— CEBINA. 
In this tribe the grinders are f f, with blunt 
tubercles. The cutting-teeth are erect and contiguous 
to the canines. The canine teeth are very large- 
The orbits have a bony septum. The tail is very long 
and hairy, and has the end convolute. The penis has 
an expanded marginal gland. Gray, in describing 
them, says they are “ gregarious, lively and wanton,” 
living on fruit and insects. 
Cebus. 
The Cebi have round and hairy tails, which, though 
prehensile to a considerable extent, is not depended 
on for locomotion. Some are, therefore, found away 
from the forests, being adapted for a life upon the 
rocks and precipitous mountain ridges. 
This genus is divided by two distinctions, C. 
fatuellus, robustus, and monachus, having five lumbar 
vertebrm, and a large head, and the remaining species 
having six lumbar vertebrae, with small head. 
SAI [Celus capucinus), also called theAYEEPER. — 
The Brazils form the natural habitat of the Capu- 
cins, so-called ; this latter term seems to have arisen 
from the curious monk-like aspect of many of the 
species, particularly about the head. These Monkeys 
are quite intelligent, sprightly, and have curious, 
quaint motions that render them always attractive. 
Their food is of a mixed character, feeding on insects 
and vegetables ; they will also eat eggs, robbing nests 
for the purpose, and will not overlook even the 
feathered kind upon occasion. 
THE BROWN CAPUCHIN (Cebus fatuellics)—Tlate 
2, fig. 7 — is sometimes called the Horned AIonkey, and 
is a fair representative of the genus called, sometimes, 
Sapajous, They are reputed to be the most mis- 
chievous of the Monkey tribe. They have the tails 
covered by hair, and differ from others in not having 
them prehensile. From their plaintive cry, the term 
AVeepers has been applied to each of the group. 
They are very mild and gentle, and easily tamed. 
The present species is characterized by an erect fringe
