Stover, L.E., 1975; Observations on some Australian dinoflagellates. Geoscience and Man vol.11 pp.35-45 pl.3 Abstract: Revised descriptions and interpretations are presented for five species of Australian Eocene dinoflagellates based primarily on abundant specimens from newly collected and processed samples, and to a lesser extent on the examination of type specimens. These species, whose processes or peritabular ridges reflect a basic gonyaulacacean tabulation, were described originally as Cannosphaerop urnaformis Cookson, Hystrichosphaeridium floripes Deflandre & Cookson, Schematophora speciosa Deflandre & Cookson, Eisenackia ornata Cookson & Eisenack, and Aireiana verrucosa Cookson & Eisenack. For the first species, the new genus Emmetrocysta is proposed with E. urnaformis as its type species; Hystrichosphaeridium floripes is transferred to Homotryblium Davey & Williams. The reflected tabulation and other features on Schematophora speciosa and Eisenackia ornata are analysed and compared, and the process formula for Aireiana verrucosa is divulged.
