Editors' Notes
[Frizzell (1951, p. 24) designates Trematodiscus orbiculatus Haeckel in Haeckel, 1862, p. 492, as the type species of Trematodiscus. However, a larger concept of this species was first described in 1860 at the time of the original generic description, and we here assume Frizzell's designation to include this 1860 form.]
