The Hainan mole, Mogera hainana Thomas, 1910, was recorded to be collected by “a native employed by Mr. Alan Owston” in the original description of the species. We noticed the specimen tag of the holotype was printed and handwritten in Japanese characters. The same tag was attached to another specimen of this species deposited at the Forestory and Forest Products Research Institute (Tsukuba, Ibaraki, Japan). Those specimens were both collected in November, 1906; therefore, the Hainan mole was collected by a Japanese person who visited Hainan Island in this period. We searched for the same form of specimen tags, and found many among bird specimens from Hainan Island at the Yamashina Ornithological Institute (Abiko, Chiba, Japan). In this period, Zensaku Katsumata collected the birds in Hainan Isl. and sent them to the Lord of Lionel Walter Rothschild in England. We estimated the type series of the Hainan mole was also collected by Z. Katsumata, who was a collector employed by a merchant A. Owston, and he sent it to L. W. Rothschild in UK. L. W. Rothschild communicated with the Natural History Museum and his name was dedicated to 18 mammalian species by researchers of this museum. It is possible to consider that Rothschild’s mammalian collection was presented to the Natural History Museum and examined by mammal researchers. Although Zensaku Katsumata was an obscure person in mammalogy, we discuss his contribution to the dawn of natural history in Japan.

旧食虫類における多系統的な形質を機能形態学的に検討した。筋骨格系、消化器系、泌尿生殖器系、感覚器系、皮膚・表皮系などを旧食虫類の諸目間で形態学的に比較検討を行った。その結果、それぞれの器官において、形態学的類似や差異を確認することができ、真無盲腸目、皮翼目、登攀目、アフリカトガリネズミ目などの旧食虫類諸群間の多系統的進化史理論を確立することができた。

The taxonomy of Japanese moles, genus Mogera, has been confused since the early 1990s, because of the poorly defined type locality of M. wogura and morphological variability within the genus. Genetic research in recent decades has clarified the taxonomic problems of Japanese moles. This paper uses Japanese moles to discuss the importance of karyological study in mammal species recognition. Chromosomal rearrangements are considered likely to have an important role in species diversification of Japanese moles, resulting from postmating isolation mechanisms induced by abnormal meiosis in heterozygotic hybrids. It is well known that recombination leads to gametes with an unbalanced complement of chromosomal segments in inversion or reciprocal translocation heterozygotes. In the case of Japanese moles, four species of Japanese moles, M. etigo, M. imaizumii, M. tokudae and M. wogura, each have a distinct karyotype and/or morphological traits, and are thus considered to be full species endemic to Honshu, Shikoku and Kyushu.
