Abstract: During the fieldwork in the past several years, a great number of Paleocene mammals were collected from Qianshan Basin in Anhui Province. Of all the mammalian fossils recovered in recent years, only some of a few taxa, e.g. Anagalidae and Pantodonta, have been described (Hu, 1993; Wang, 1993; Wang et al., 1992). Here described specimens, a pair of lower jaws and two fragments of one left maxilla of the same individual, were found from the lower part of Upper Member of Wanghudun Formation (Middle Paleocene) in the summer of 1993 and probably represent a mixotheridian. In this paper, the five premolar mode for primitive eutherian dentition (see McKenna, 1975; Novacek, 1986b) is adopted during the description and comparison. P 4 and P 5 of Kennalestes, Asioryctes, Zalambdalestes, Barunlestes, Praolestes, palaeoryctids and leptictids narrated in comparison section of the present paper are respectively corresponding to P 3 and P4 in original description of these genera. The measurements of teeth were made under the Wild M 7 A microscope by following Novacek's (1976) method.

摘要： 产于潜山盆地中古新统望虎墩组上段的混兽目(Mixotheridia)的新属种—周氏安徽兽(Wania chowi gen. et sp. nov.)，主要特征是:齿式?•1•3(?)•2+ ?/?•1•3•3，上颊齿外架窄，外中凹浅，附尖不发育，P5后尖明显，臼齿向后显著变小，P5及M3下跟座均具两个小尖。与该目中两个科Zhelestidae、Zalambdalestidae的成员相比，Wania在牙齿结构上更接近于Zhelestidae的成员，而且它不具有Zalambdalestidae科的典型特征，本
