Septifer cumingii Récluz, 1849

Material examined: Sta. 10, 1 sp., rocky habitat, 0.1–3 m depth.

Description: Shell light green with pinkish spots, solid, with subtriangular shape, equivalve and inequilateral. Ligament is internal and covers the greater part of the anterodorsal margin. Hinge line with 2–3 large teeth in line of umbo and 4–6 dysodont teeth behind the ligament. Internal margins crenulated. On the shell, towards the posterior, there are numerous bifurcate longitudinal ribs and concentric lines. An available septum on the anterior end.

This species is similar to Brachidontes pharaonis (Fischer, 1870) , but it can be easily distinguished from it by its internal septum, which B. pharaonis lacks.

Distribution: Worldwide, the species is distributed in the Indo-Pacific Ocean and the eastern Mediterranean ( Oliver, 1992: 48; Scaperrotta et al., 2012: 127). Along the Turkish coast, the species was previously reported from the Levantine Sea by Albayrak and Çeviker (2001: 297).
