A bonnet troop inhabiting Lal Bagh, Bangalore (Hafeezur Rahaman & Parthasarathy, 1967) was exclusively studied for its communicative behavior. The whole system of the bonnet organization is based on composite expressions. Depending on situations, individual signals or a complex of them involving tactile, visual, auditory, and olfactory are passed from one individual to the other. Among tactile signals the most important one is the grooming; among visual the body movement, more particularly the face and jaws; among auditory the groaning and shrieking; among olfactory the sniffing. Analysis of such a study reveals that the bonnet monkeys have a communicative system and an organization of their own, which though principally are the same as in other primates, do entail a few minor differences. These features though primitive from the standards of human consideration, are developed to their full advantage, but still remain at a primitive level. By far, the greatest part of the whole system of communication seems to be devoted to the organization, of the social behavior of the group, to dominance and subordination, the maintenance of peace and cohesion of the group, reproduction and care of the young (Marler, 1965).
