Circles indicate the points where the frogs were cap- tured. Solid circles indicate adult frogs and open cir- cles indicate yearling frogs. Other symbols are the same as in Fig. 2. of individuals in the process of dispersal was comparatively small. When an individual was recaptured at more than one point, the greater value was adopted. We show the migrating dis- tances by the frequency distribution of 25 m individuals (Figs. 5, 6). A small number of ind- viduals of both species were found about 500 m away from the spawning sites but most of the individuals were found within 250 to 300 m. Table 2 shows the range of migrating dis- tances. Rana Japonica has an average migrat- ing distance of 145 m (yearlings, N=158) and 114 m (adults, N=48). Rana ornativentris has an average of 186 m (yearlings, N=122) and 204 m (adults, N=29). Thus, 90% of the indi- viduals found at this time were dispersed within the range from 200 to 270 m {R. japon- ica) and from 330 to 390 m (/?. ornativentris). 75% of these were in the range from 150 to 200 m {R. japonica) and about 270 m {R. orna- tiventris)..
