 note = {In the alluvial areas of Shikoku, there are topographically two forms of natural elevation: one is named as a “branch" of mountains connected with the main part of mountain ranges of Shikoku such as the Mountain Ranges of Sanuki, Ishizuchi and Shikoku; the other form like hill is named as an “island" lied isolately over the alluvila planis. From 1979 to 1986, the collecting for Apodemus speciosus, A. argenteus and Eothenomys smithii was carried out at some habitats on the two forms in Shikoku during February and March, when the number of E. smithii collected at lower altitude increased to the highest throughout a year. As a result, A. speciosus was collected on the two forms, whereas E. smithii occurred only at “brances". A. argenteus was captured mainly on “branches" and partly on “islands" just near “branches". These specific distribution patterns found in the three species are named as “topographic distribution", which is an intermediate category between geographical and ecological distributions. The same tendencies of the specific patterns can be referred to previous reports on the collecting of the small rodents over the alluvial areas: Okazaki-Toyohashi District and Kantou District (central Honshu). The reason of this specific topographic distribution was discussed from four points of view mentioned below: 1, specific differences of the duration afte the appearence of the species in geological times; 2, specific differences of the minium limit of “island" area where the species can survive; 3, specific differences of the barrier effect by the alluvial plains; 4, specific differences of the ablities of diffusion and migration.},
