Comparative anatomy of various sorts of the triangles formed by cranial curvature and hypophyseal point on the cranial median section of the Cynomolgus monkey was studied craniometrically.
The following conclusions were obtained.
1. In ΔAPB of the Cynomolgus monkey, ∠APB and ∠PBA showed the intermediates of the respective angles of the Orang-Utan and the Chimpanzee, and ∠PAB showed those of the Macacus fuscatus (Blyth) and the Gibbon.
2. In ΔAPN, ∠PNA and ∠APN showed the intermediates of the respective angles of the Macacus fuscatus and the Gorilla, and L PAN showed those of the former and the Gibbon.
3. The three angles of LANB lay between those of the Gorilla and the human being.
4. The three angles of LPNB lay between those of the Macacus f uscatus and the Orang-Utan.
5. The hypophyseal triangles of the Cynomolgus monkey generally seemed to resemble to those of the Orang-Utan and the Chimpanzee more respectively than those of other animals.
