Abstract: Wutu Basin is a small Paleogene sedimentary basin, situated about 17Okm east of Jinan, the capital of Shandong Province. An index fossil of Early Eocene, Homogalax wuzunensis, has been reported from the Wutu Formation by Chow and Li (1963, 1965). Recent collecting not only has produced extensive statistically-significant samples, but also has yielded uncommon specimens of micromammals. In this paper a soricomorph insectivoran is described.

摘要： 山东早始新世五图组曾发现原始獏类，Homogalax mutunensis，最近又采到一批化石。这里仅记述其中的一种食虫类，可归人鼩形亚目的昌乐鼩(Changlelestes dissetiformis gen. et sp. nov.)。昌乐鼩与亚洲早第三纪食虫类(Ernosorex, Ictopidium和Tupaiodon)可能有较为密切的亲缘关系，本文将它们归人新科—Changlelestidae fam. nov.。昌乐鼩科与Plesiosoricidae和Soricidae有一些相同的进步
