Abstract: Gazella blacki was named by Teilhard and Young (1931) on the basis of the specimens from the Pliocene of Hefeng, Jingle District, Shanxi Province. The syntypus comprise 9 horn cores, 25 more or less complete mandibles and many broken limb bones. In 1938, Teilhard de Chardin P. and Trassaert M. referred a great number of specimens from Yushe Basin, Shanxi Province to this species and proposed its amended diagnosis. Since then, G. blacki has been considered as one of the typical elements in the Late Pliocene mammalian fauna of Northern China. After restudying the Yushe's materials assigned to the genus Gazella, I think that the so—called species G. blacki is mixed. Besides the species itself, it may contain G. sinensis and other new gazelle forms. In fact, G. blacki represented by the specimens of Hefeng is a valid species, and it is useful for dating the beds bearing it Therefore, it is necessary to clarify the conception and to give a revised diagnosis of this species by observing the Hefeng's samples. It is the purpose of this paper.

摘要： 重新厘定后，步氏羚羊(Gazella blacki)的主要特征是个体中等大小，脑颅部宽而短，枕面向后突出不明显，枕裸与枕面处在同一平面中，基枕面平，呈方形，具宽浅而长的中纵沟;角心纤细，短而直，从角基向角顶方向迅速变尖，基部横切面为次圆形;颊齿高冠，前臼齿列短和P4有封闭的前内谷等。它出现在我国山西上上新统的地层中。依据头骨和颊齿的性状，它可能是现生种G. picticaudata和G. gutturosa的祖先类型。
