• The sutural or contact types among frontal, parietal, temporal and sphenoidal bones of skulls were investigated osteologically in various mammals.<BR>The sutual type of the region of the pterion of skulls in Japanese domestic cats was the parieto-sphenoidal one in all 52 specimens examined. The contact pattern of the parieto-sphenoidal suture in the outer and inner faces of the skull differ from individual to individual in respect to its width and position. Its variations are given in Figs. 1 and 2. The parieto-sphenoidal contact on the outer face of the skull, indicates the possibility of a parieto-sphenoidal suture occurring on the inner face, on the same side.<BR>From the comparative-anatomy standpoint, the sutural type of the region of the pterion in the outer face of the skull of Rodentia (rabbit and marmot), Non-ruminants (pig and wild boarn) and Perissodactyla (thorough bred horse and pony) is in general the fronto-temporal one. The fronto-temporal suture is formed usually in the goat but rather rare in cattle. This type in a serow (<I>Cap-ricornis crispus crispus</I> Temminck, 1837) resembled the main pattern of the parieto-sphenoidal contact in cattle.The parieto-sphenoidal suture is formed generally in Primates (man) and Carnivora (lion, Japanese black bear and mongrel dog) except for a red fox which showed the fronto-temporal contact. (See Fig. 3)<BR>The parieto-spheno-front-temporal contact was not detected for sure in all the mammals examined in the present study.
