. The brain from ape to man; a contribution to the study of the evolution and development of the human brain. Brain; Evolution; Pongidae. DORSAL SURFACE OF BRAIN, PAPIO CVNOCEPHALUS. [Actual Length 77 mm.] Key to Diagram, sulc. p. inf., Sulcus Precentralis Inferior; sulcus retrocentralis inf., Sulcus Rctro- centralis Inferior; sulcus temporalis Sulcus Temporalis Superior. Stands out sharply because of its marked orbital concavity into which the orbital plate of the frontal bone projects. A well-defined hssure of Sylvius extends backward and upward, more oblique m its general direction than that seen in the lower primates. It demarcates a well-defined temporal lobe the tip of which projects forward for a considerable distance, giving it partic- ular prominence in front of the horizontal limb of the fissure of Sylvius. A well-marked and long sulcus simiarum separates the parietal from the occip- ital lobe, thus completing the topographical outline of the major hemi- spheral lobes on the convexity of the brain. The convolutions and fissures are richest and most complex in the parietal and temporal lobes, and least pronounced in the frontal lobe. The entire surface configuration and the arrangement of the fissures produce the impression of a gyrencephalic pat-.
