摘要：
Ammonites of the genus Lissoceras from the Upper Bajocian of Karachay-Cherkessia are discussed. The new material, represented exclusively by macroconchs of different age stages, makes it possible to clarify the taxonomic composition of this genus in the basin of the Kuban River. The new taxa L. kubanense sp. nov. from the lowermost horizons of the Niortense Zone, and L. paviai sp. nov. from the middle part of this zone, are established. Single specimens of L. meletense (Parona) (upper part of the Niortense Zone), L. ovale Pavia et Fernandez-Lopez (lower part of the Garantiana Zone), and L. haugi Sturani (lower part of the Parkinsoni Zone) were found. The description and images of the ammonites are given.
