In Mt. Taisetu all species of Muridae occurring in Hokkaido have been found except Mus molossinus. In August of 1951, in the mixed forest around Matuyama hot spring (alt. 800m), Apodemus ainu ainu occurred predominating over Apodemus geisha and Clethrionomys rufocanus bedfordiae. In August of 1955, there occurred C. r bedfordiae, C. rutilus mikado and A. geisha in the mixed forest around Yukomanbetu hot spring (alt. 1000m), of which the first seemed dominant. Though it might be local and temporal, the dominancy of C. r. bedfordiae in the forest would probably due to the thick growing of bamboo grass resulting from the cutting of the trees. At the alpine grass zone (alt. 1900m) of Mt. Tomurausi, an adult male of C. rutilus mikado was caught. At the top of Mt. Kurodake (alt. 1984m), C. rutilus mikado occurred exclusively under the alpine dwarf pines and in the lava zone, while in the alpine grass zone no vole was obtained. Clethrionomys yesomontanus was recorded by Kishida ('31) as a new species from the top of this mountain. However it is certainly conspecific with C. r. mikado as has already been suggested by Tokuda ('41). Rattus norvegicus was obtained by the watchman in the mountain hut situating on the top of Mt. Kurodake. Surely it had migrated from the mountain foot. Rattus rattus was caught in the building of the inn of Matuyama hot spring. This had been probably transported with the loads for the inn.
