As a step toward elucidating the causes and mechanism of brachycephalization, correlations between neurocranial and ulnar/radial measurements were examined by principal component analysis and Kaiser's normal varimax rotation methods. The results based on 30 male and 20 female skeletons of modern Japanese showed that cranial length was significantly associated with some measurements of the ulna and the radius only in males. This and previous findings suggest that, while cranial breadth has no or little association with any measurements of the upper limb bones, cranial length is differentially associated with them, i.e., strongly associated with many measurements of the humerus; considerably with some measurements of the male scapula, ulna and radius; and not with any measurements of the clavicle. Although the causes for this differential association of cranial length with upper limb bone measurements are not determinable for the present, a possibility was discussed from the viewpoint of osteogenesis.
