12 PRIMATES. 
In Mexico Professor Reinhardt remarks that this species was obtained by the late 
Professor Liebmann at Mirador, near the Volcano of Orizaba, in the State of Vera Cruz, 
where it was common, living in small troops in the deep ravines up to an elevation 
of 2000 feet. He also found it at a height of 4000 feet in the eastern parts of Oaxaca, 
but never on the Pacific slope of the Cordillera in that State; and he believed that 
Monkeys were not to be found on the western coast further north than Tehuantepec ?. 
Professor Reinhardt therefore suggests that there may have been some error as to 
the exact locality of M. Boucard’s specimen figured by Mr. Sclater 4, said to be from’ 
Acapulco, and that it had probably been brought to that port from the eastern side of 
the Cordillera. 
Deppe’s example, now in the Berlin Museum (formerly believed to belong to the 
last species)4, was also from Vera Cruz, having been taken alive not far from Alvarado. 
Lastly, M. Sallé informed Mr. Sclater that the most northern locality for “Monkeys 
with which he was acquainted was in the State of San Luis Potosi, about 23° N, lat., 
in the upper part of the basin of the Tampico River !.

The Capuchins or Sapajous are smaller than the Spider-Monkeys, have more mode- 
rately developed limbs, perfect thumbs, and completely haired tails, which are less 
strongly prehensile than in the genera already treated of. They are also much more 
active and lively in disposition, and, being easily tamed, they are oftener seen in cap- 
tivity than any of the other American Monkeys. 
The range of the genus extends throughout the greater part of the Neotropical 
Region, from Paraguay in the south to Nicaragua in the north. A close general 
resemblance of the species, and a large amount of individual variation, make the 
Capuchins almost as difficult a genus as Ateles, the number of distinct species having 
been variously estimated at from one to forty. Professor Schlegel, who regards twelve 
forms as deserving separation, characterizes a small group of the most northern species, 
which have only five lumbar vertebra, instead of six, and which agree in their general 
coloration. Of these the only Central-American form (C. hypolewcus) may at once be 
distinguished from C. albifrons (Humb.) by the white of the breast being extended 
over the shoulders and arms, while the White-headed Sapajou of Guiana, C. capucinus 
(Linn.), is at once separated by its isolated black cap.
