摘要：
The ammonites of the genus Cadomites from the Upper Bajocian and Lower Bathonian of Karachay-Cherkessia are discussed. The new material makes it possible to precisely identify macroconchs of this genus in the Kuban River basin. C. (Cadomites) lissajousi Roche is described from the middle Subzone of the Upper Bajocian Niortense Zone. C. (C.) sturanii Westermann et Rioult is described from a talus of the Upper Bajocian Parkinsoni Zone-Lower Bathonian Zigzag Zone boundary beds. C. (C.) ex gr. rectelobatus (v. Hauer) and C. (C.) sp. are also found in this locality. A new species C. (C.) zelenchukensis Mitta sp. nov. is described from the lowermost Lower Bathonian (Beds with Oraniceras scythicum).
