Basionym: Peridinium depressum Bailey 1854. Smithson. Contr. Knowl. 7: 12, Figs. 33–34.

Description: Cells large, pentagonal, dorsoventrally compressed, asymmetrical. The apical horn elongated. The apical pore structure of Bʹ– type (Toriumi & Dodge 1993). The epithecal plate pattern comprises seven precingular plates (7ʹʹ), four apical plates (4ʹ), three anterior intercalary plates (3a), 1ʹ and 2a plates of “ortho”–”quadra” type. Thecal plates reticulate. The cingulum median, descending (displaced by 1.0 cingular width), bordered. The sulcus deep, with narrow sulcal lists. The hypotheca with sharp diverging antapical horns. The cellular contents pink or brown-red. Dimensions: 96.2–129.8 μm long and 82.2–97.7 μm wide.

Distribution: Coastal and oceanic, even forms blooms in warm water estuaries. Temperate to tropical waters; cosmopolitan (Steidinger & Tangen 1997). Data on the distribution of P. depressum are given from the GBIF.org (2022) (Fig. 84).
