CALLICEBUS Thomas, Ann. Mag. Nat. Hist., 7th Ser., XII, 1903, pp. 

 456, 457. Type Callithrix personatus E. Geoffroy. 

 Saguinus Less., Man. Mamm., 1827, p. 56, (nee Sagouin Lacep., 



1799; nee Illig., 1811). 

 Callithrix Auct., (nee Erxleben). 



Head small, depressed; eyes small; ears large; tail long, bushy. 

 Skull lacks backward extension, such as exists among the species of 

 Saimiri; canines small ; angle of mandible only moderately expanded. 



The Titi Monkeys, as the members of this genus are usually called, 

 are active creatures, but less lively than the Sapajou or Capuchins, and 

 Bates says that C. moloch is a dull, listless animal. But according to 

 his own account, it is agile enough in the trees. Their food consists of 

 fruits, insects, birds' eggs, and small birds whenever they succeed in 

 capturing one. Their range is extensive, comprising the greater part of 

 Brazil, and they are also natives of Colombia, Ecuador, Peru, and 

 Bolivia.
