ABSTRACT
I n defining the primate group we must accept the limitation of criteria which transform every anthropological term when i t is applied to animals. A l l subjective phenomena of group life-like "identification" or "identity of aims"—are lost for the study of animal groups, because their members lack the symbols for their expression. Definitions of animal groups are restricted to so-called objective criteria because they are the only criteria available. Only the student of human societies is in the enviable position of using and com paring both kinds of characters, what people do and what they feel.
