Abstract
The first metacarpal bones of the Amud man, a Neanderthal man found in West Asia in 1961, was described by the present author in 1970. In that paper, he was mistaken the bone in regard to its side. The corrected new description on the first metacarpals of the Amud man was given in this paper.
The author reexamind the differences between the right and left first metacarpals on the recent and prehistoric bones. The radial impression for the M. opponens pollicis develops well to become a flange on the Amud bone. This characteristic can not only be seen in the Neanderthal man but is also seen in the muscular prehistoric people.
