Twenty seven sooty mangabeys (Cercocebus atys) were used in a series of experiments concerned with the effects of introductory technique upon group formation. The number of animals introduced, the number of animals resident and the age and sex characteristics of the newcomers and residents all influenced the nature of initial interactions. When preformed groups were introduced to each other another level of complexity was introduced inasmuch as the physical limitations of the test situation precluded permanent maintenance of two group structures. The reception of newcomers was similar to that described in macaque experiments but group integrative mechanisms were clearly still in progress at the conclusion of the experimental period. A well organized successful breeding group has emerged from these experiments.
