Three hundred specimens of small mammals, belonging to 10 species, were collected in Mt. Goyo (about 15km west of Kamaishi City, Iwate Pref.) and Mt. Hayachine (about 40km southeast of Morioka City, Iwate Pref.) during a short trip in the early summer of 1967. The most interesting mammals among them was Euroscaptor mizura mizura (GUNTHER, 1880) which was collected at the upper part of Tatamiishi (1100m alt.), Mt. Goyo. The subspecies is a rare animal in Japan and the specimen obtained here is the 8th record from the country, and, at the same time, new to the Tohoku district, Honshu. One of the most difficult problems of taxonomy among the Japanese small mammals is the status of Aschizomys andersoni (THOMAS, 1905) from northern Honshu. Twenty-one specimens of this species were collected during the trip to Mt. Goyo and Mt. Hayachine, and studied statistically by a simplified method employing the association coefficient in numerical taxonomy. The dendrogram (Fig. 1) made by the method clearly expresses the similarity of the Goyo-Hayachine populations to the population from Mt. Zao and, onthe other hand, the distinction between them and the other populations of central Honshu. These morphological relationships and the differentiation of the vertical distribution recognized among groups of Aschizomys in Honshu indicate the specific distinction of Aschizomys andersoni, which is represented by the populations of Mt. Goyo, Mt. Hayachine or Mt. Zao, from A. niigatae of central Honshu. The small mammal fauna of Mt. Goyo is peculiar among those of mountains of the Tohoku district in having the combination of Euroscaptor mizura mizura and Aschizomys andersoni, while that of Mt. Hayachine seems to be similar to the latter, although it could not be fully clarified by the present survey.
