Abstract: An individual of Laxmann’s shrew (Sorex caetutiens Laxmann, 1788) with completely white pelage was captured on 5 December, 2011 in Hamanaka-cho, Hokkaido, Japan. It was captured alive by a house cat and kept in a cage until it died on 12 May, 2012. It is the first record of S. caetutiens with a completely white pelage in Japan. Owing to its pinkish skin and iris, it seems to be albinistic rather than leucistic, although the gene causing the white pelage has not been determined yet. This specimen (skin, skull and bodies in ethanol) was tentatively deposited at the Institute of Low Temperature Science, Hokkaido University.
2011年12月5日に北海道浜中町において全身が白色のバイカルトガリネズミSorex caetutiens Laxmann,1788(エゾトガリネズミ)が捕獲された.この個体は飼いネコにより牛舎付近で生きたまま捕獲された後,飼育され2012年5月12日に死亡した.全身が白色のバイカルトガリネズミの報告は日本においてこれが初めての記録である.この全身白色の毛色を発現させた遺伝子は未調査であるが,ピンクの地肌とピンクの目から判断するとアルビノの可能性が高いと思われる.
