Editors' Notes
[Frizzell [Frizzell and Middour,1951 p.24] designates Trematodiscus orbiculatus Haeckel in Haeckel, 1862 as the type species of Porodiscus; Campbell [1954, p.D89] designates Flustrella concentrica Ehrenberg, 1838. However, these seem inappropriate as neither species was among those first subsequently assigned to Porodiscus. Species first subsequently assigned to Porodiscus are: Porodiscus communis Rust, 1885b; P.nuesslinii Rust, 1885b; P.simplex Rust, 1885b.]
