The author caught small mammals in the Okushibu district situated in the subalpine forest of the Yatsugatake range from May, 1963,to April, 1965,and collected the fleas from them. Ten species of small mammals were caught ; and C. andersoni, A. argenteus, D. pilirostris and S. shinto were characteristic ones of this district. Thirteen species of fleas were recorded from these hosts. The fleas were most abundant on D. pilirostris, moderate on C. andersoni and S. shinto, and very few occurred on A. argenteus. The flea-index for the total of 665 examined hosts was 0.9. The type of the distribution of the fleas on the host animals was determined as negative binominal distribution. As to the seasonal occurrence of the fleas, five species were winter fleas, namely, S. montana, S. tokudai, P. miyama, P. udagawai and C. striata and were found in the months between October and May. Although there were no summer fleas, H. ozeana and P. nippon were observed to be more common in the warmer months. And H. ozeana was like a rival flea of the two winter fleas of the genus Stenoponia. There was another category of seasonal occurrence, containing D. coreana and M. andersoni which were collected both in warmer months and in colder months. The host-flea relationships were also studied. Only exceptionally was a species of flea collected from only one host species. The comparison of numbers of the fleas obtained with those of the hosts examined, however, revealed the degree of host specificity. Of twelve fleas, nine had only one true host, two had two true hosts and only one flea had more than three true hosts.
