Nomenclatural notes
Moestrup & Calado (2018: 469) "Cell discoid (only one seen!), concave ventrally, convex dorsally. Theca of large, thin plates. Cingulum distinct, making only three quarters of a turn and appearing to terminate in a flat ventral area as in Ceratium (a "shield"). The two sides of the sulcus distinct. Chloroplasts absent. Nucleus below a large central vacuole. No eyespot. Length and width: ca. 300 µm! (perhaps a mistake for 30 µm?), thickness ca. 10 µm. Cell movement quick, accompanied by rotation. Penard compares the path of the cingulum with Ceratium and his pl. IV, fig. 6 resembles a Ceratium cell seen from the posterior end. The single cell of G. girans found by Penard may have been a recently germinated cell of Ceratium (the gymnoceratium stage), or perhaps a teratological cell (see Huber & Nipkow 1923). The name was included in a list of uncertain species by Schilling (1913) and it is absent from more recent floras." - (28 Aug 2020) - M.D. Guiry
