HABITS.--This species, called "Mico Maizero" by the inhabitants of Tolima, lives as all the _Cebi_ do, in considerable troops in the forests. When wild, it is restless and destructive, but in captivity it is docile and affectionate. VI. THE VARIEGATED CAPUCHIN. CEBUS VARIEGATUS. _Cebus variegatus_, Geoffr., Ann.
