OHBAYASHIPilirostris TRUE. From U. talpoides, YAMAGUTI (1954) described a new trematode,Brachylaima tokudai, and OHBAYASHI et al. (1972 & 1973) reported ten helminthspecies including four new ones (tab. 1). On the other hand, CHABAUD et al. (1963)found StrongyloideS Sp. from D. pilirostris.Recently, the author had a chance to examine parasites of D. pilirostris. Thestudy was based on four animals made available by the courtesy of Dr. ToshiakiMASEGI, Anatomical Section, Institute of Stomatognathic Science, Tokyo Medicaland Dental University, Tokyo. From these cases, four neJnatOde and one acan-thocephalan species were collected, and the incidence was compared with that ofU･ talpoides (tab. 1). The data concerning U. talpoides were obtained from the■materials used in the serial studies by OHBAYASHI et al. above noted.As shown in the table, a considerably high incidence of helminths was obtainedin three nematodes, Thominx wotrichi, AngiostrongTylus minutus and Spiruran妙onensis, and it can be concluded that the helminth faunae of the two hostanimals are quite similar to each other. The juvenile form of Centrorhy71Chuselongatum is the丘rst record from the shrew moles in Japan, but it can be commonlyfound soricine hosts in this country. MACHIDA and FUJIMAKI (1965) detected it ina specimen of Sorer unguiculatus DoBSON in Hokkaido. On the other hand, theauthor couldfind this form in all 4 Sorer shinto THOMAS and 6 S. unguiculatuscollected in the suburbs of Sapporo during a period from February to May, 1973(data unpublished).REFERENCESl) CHABAUD, A.
