The anatomy of the wrist of the Japanese giant flying squirrel <i>Petaurista leucogenys</i> was investigated, and, on the basis of myological data, a hypothesis was formed concerning the origin of the long accessory styliform cartilage supporting the flying membrane. The styliform cartilage in the forelimb of <i>P. leucogenys</i> lies along the ulnar side; its length is almost equivalent to that of the radioulna. During the present study, it was recognised that both the <i>flexor carpi ulnaris</i> muscle and the flexor retinaculum attach to the proximal end of the styliform cartilage. The results of our anatomical studies suggest that in <i>P. leucogenys</i>, the styliform cartilage is essentially homologous to the pisiform bone in other mammals and is presumed to have originally been derived from a sesamoid bone.
