Homing behaviors of two species of limpets, Siphonaria japonica and Patelloida saccharina lanx, were studied at the sea shore of the vicinity of the Seto Marine Biological Laboratory. These two species show homing behavior in summer. The distances of locomotion are generally limited within 5-10cm. When returning home, many of them creep along the tracks made during their leave, but some of them can return without following the same track. When they are translocated artificially 5,10,15cm apart from their homes, some of them can return, the rates of which are shown in Table 2. In these experiments, many individuals took direct courses to their homes. From these observations, it may be considered that these species can return home by following the tracks first made on the one hand, and by memory of the topographical features on the other. The latter seems to be more and more established with the elapse of time since the animal inhabits a certain site.
