Thirty-one demes of Rhinolophus ferrumequinum (SCHREBER, 1774) from the Kii, the Chugoku, the Tanba and the Suzuka Mountains, Honshu, Japan, were examined. The mean values of the forearm lengths of the Chugoku samples linearly correlate with the latitudes of their collecting sites. The regression line of this Chugoku group is shown by the forms : Y_c=3.28+1.61 X, Sys=0.379,γ=0.862. The mean values of the forearm lengths of the Kii demes are not contained in the range of Y_c±3Sys of the Chugoku group of R.f. nippon TEMMINCK, 1835,being larger than those of the latter. Consequently, the Kii demes remarkably differ from the Chugoku group and probably belong to the larger form of R.f. mikadoi OGNEV, 1927,which is distributed over Shikoku and the central part of Kyushu. The larger form and the Chugoku group of this species seem to occupy different areas, that is, the former is distributed on the southern side of the Median Tectonic Line of Southwest Japan and the latter on its northern side.
