摘　　要：重新厘定后，步氏羚羊（Gazellablacki）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，枕髁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，从角基向角项方向迅速变尖，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。Gazella blacki was named by Teilhard and Young (1931) on the basis of the speci-mens from the Pliocene of Hefeng, Jingle District, Shanxi Province. The syntypuscomprise 9 hom cores, 25 more or less complete mandibles and many broken limbbones. In 1938, Teilhard de Chardin P. and Trassaert M. referred a great number ofspecimens from Yushe Basin, Shanxi Province to this species and proposed itsamended diagnosis. Since then, G. blacki has been considered as one of the typicalelements in the Late Pliocene mammalian faun of Northem China.After restudying the Yushe's marerials assigned to the genus Gazella, I think thatthe 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 specimensof 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 speciesby observing the Hefeng's sampes. It is the Purpose of this paper.
