Material. A single, incomplete right valve from the lower member at Langza (SNSB-BSPG 2020 XCIX 11). Description. Somewhat abraded right valve with ventral part missing. Early disc suborbicular, equilateral, poorly inflated. Auricles well-demarcated from disc. Posterior auricle relatively small, forming obtuse angle with disc. Disc with ~19 radial plicae plus some very faint ones near anterior and posterior end. Number of plicae increasing ventrally by bifurcating. No growth lines or commarginal lamellae seen due to poor preservation. Remarks. The poorly preserved specimen can be placed in Chlamys (C.) textoria with reservation only.
