Tribe of Monkeys with Non-Prehensile Tails. — To the 
category of Monkeys with non-prehensile tails belong the genera 
Callithrix, Saimiri, Nocthora, and Saki. 
Genus Callithrix . — The Callithrix, Sagouins, or Tee-Tees, are 
nearly the same size as Squirrels; the pelage is abundant, and 
their tail long and very hairy. These are nocturnal or crepuscular 
animals, and live on trees or in brushwood, feeding chiefly on fruits 
or insects. They are full of vivacity and gentleness, and readily

adapt themselves to captivity ; but their intelligence is only of a 
medium standard. They are all natives of Brazil and Peru. Two 
pretty species, the Ruffled and the Collared Tee-Tee (Fig. 249), 
are remarkable for a thick white beard, which contrasts strongly 
with the deep brown of their coat. 
Genus Saimiri . — The Saimiris, or Squirrel-Monkeys, are little, 
quick-moving animals with a sprightly countenance, and not unlike 
the Squirrels in character and size, as their name implies. They 
have the brain well developed, and are remarkably intelligent. 
Nocturnal, like the preceding, they live nearly in the same fashion, 
loving to seclude themselves in coppices and in well- wooded locali- 
ties ; they even occasionally inhabit holes in rocks. They are carni- 
vorous, for they eagerly pursue not only small birds, but also certain 
species of Mammals. Guiana and Brazil are their native country.
