The present study, including Anisocycla, Eulimella, Puposyrnola, Syrnola and Turbonilla genera, is the third one dealing with the species having heterostrophic protoconch distributed along the Turkish coasts, following the genus Chrysallida and the subfamily Odostomiinae. The material was collected in the Turkish Levantine and Aegean Seas, and the Sea of Marmara at depths varying from 0.5 to 1302 m between the years 1996 and 2012. The examination of the collected material revealed four species of Anisocycla (A. gradata, A. nitidissima, A. pointeli and A. striatula), five species of Eulimella (E. acicula, E. neoattenuata, E. scillae, E. ventricosa and E. unifasciata), one species of Puposyrnola (P. minuta), two species of Syrnola (S. fasciata and S. lendix) and twelve species of Turbonilla (T. acuta, T. acutissima, T. hamata, T. jeffreysi, T. lactea, T. micans, T paucistriata, T. pseudogradata, T.pumila, T. pusilla, T. rufa and T. striatula). Of the identified species, E. neoattenuata forms a new record for the eastern Mediterranean, T. paucistriata is new report for the Levantine and Aegean Seas, P. minuta and T. micans are new ones for the Aegean Sea, E. striatula and T. pseudogradata are new records for the Turkish molluscan fauna, T. acutissima is a new one for the Turkish Aegean Sea fauna and Sea of Marmara and six species (A. gradata, A. nitidissima, E. scillae, E. unifasciata, T. lactea and T. pumila) are new records for the Turkish Aegean coast. Most of the identified species are distributed in littoral depths down to 100 m, whereas E. ventricosa, T. micans and T. paucistriata are significant as species distributed at deeper bottoms, found at depths of up to 1302 m. On the other hand, out of the 23 species encountered in this study, T. rufa is the most abundant species along the Turkish coasts, however E. acicula, T. acuta and T. pusilla are species with the widest distribution.
