In the Cercopitheci the skull has a large brain-case, and that part on which the brain and cerebellum rest is concave or pitted on the petrosal bone, and on each side of the crista galli in the fore part of the skull. In general there is a laryngeal pouch. The first premolar is like that of the Semnopitheci. The other anatomical peculiarities of these and of the Semnopitheci will be found in the description of the Macaques and Baboons.
