Diagnosis. Shell triangularly-rounded, almost equivalved, almost equilateral. Transition from lateral margins to lower margin is sharp. Surface of shell is covered with concentric lines and the same fine radial costae {ribs} of Camptonectes type. Comparisons and comments. G. Boehm (1883, p. 604) called his form from the Tithonian a name suggested by K. Zittel (1866, p. 35 [111], pl. 17, fig. 9), for a Cretaceous form. Specific difference of both forms is not doubted. When taking into account what has been explained, we suggest for the form under the name Pecten fraudator Boehm, a new specific name, tcharachensis from the name of a village, Charakh (Azerbaijan, Bol’shoy Kavkaz), where we found this species. In closely related according to morphological characters Pecten fraduator {sic} Zittel (1866, p. 35 [111], pl. 17, fig. 9), the shell is relatively narrow, oval, transition from lateral margins to lower is not as sharp, anterior auricle is substantially larger than posterior. In Camptonectes (?Camptonectes) virdunensis (Buvignier, 1852), shell is strongly elongated in height. Range. Tithonian of Azerbaijan (Bol’shoy Kavkaz), Czech Republic (Shtamberg).» A. A.
