Faunistic study was made on the fresh water fishes in the streams flowing through the mountainous land of the Rikuchu district to the Pacific Ocean four times from early August to the end of October, 1967; the water systems studied here are R. Kuji, R. Akka, R. Omoto, and R. Hei; the localities of these rivers are given in a map attached to the introduction of the present Memoir. The collected specimens contain 19 species, 17 of which are supposed to be endemic. Characteristic features of the fish fauna of the district are as follows : (1) Poorness of the ture fresh water fish is noteworthy, and its comparison with other faunas in waters surrounding Rikuchu land may give a clue to the origin of the fauna. (2) All representatives of the genus Cottus in northern Japan, such as C. hilgendorfi STEINDACIINER et DODERLEIN, C. hangiongensis MORI and C. pollux GUNTHER, were collected at least in R. Omoto. This is merely a preliminary study of the fresh water fishes of this district, but the present collection seems to cover about 70% of the whole species which is expected in the district.
