Fig. s. Scanning electron micrographs. a Peridinium latispinum (= P. africanoides) with a relatively
smooth thecal surface. The small right sulcal list displaced to the proximity of the posterior flagellar
aperture is a constant feature and a revelation by scanning electron microscopy. b Dinophysis miles
var. schroeteri, a variety restricted to the vicinity of the East Indies. c Ornithocercus quadratus,
