| Comments | Information in pub. 002527: "Rev. O'Meara exhibited specimens of a diatom, the type of a new genus, which he named Ptychodiscus, and the species Ptychodiscus lineatus, from the Arran gathering; a description and figure of which is to appear in this Journal." The name was later occupied by Ptychodiscus F. Stein 1883 (Dinophyceae). Van Heurck (1896) p. 553 (ref. 000897) indicates that the name is a synonym of Coscinodiscus. |
