Genus Rissoa Desmarest, 1814

Type species: Rissoa ventricosa Desmarest, 1814 , Recent, from the Mediterranean Sea.

Remarks.— Rissoa parva from the NE Atlantic and Mediterranean Sea has frequently been regarded as the type species of Turboella Leach in Gray (1847). Ponder (1985) reported that the anatomical, radular, and protoconch characters exhibit no differences compared to Rissoa , and that the general appearance of the teleoconch is extremely similar. The diagnosis presented by Nordsieck (1972) does not support a separation of Turboella . Wenz (1938–1944) regarded Mohrensternia Stoliczka, 1865 as a synonym of “ Turboella ”, which is herein rejected (see discussion of Mohrensterniinae ).
