Abstract
Light and electron miscroscope observations show that Ophiaster cells have centrally placed spines on coccoliths surrounding the area where the two flagella emerge. The spectacular starlike appendage is located at the opposite cell pole. Two species are suggested retained: Ophiaster formosus Gran and Ophiaster hydroideus (Lohm.) Lohm., distinguished by differences in the morphology of their appendices. Syracosphaera confusa Halldal & Markali is included in the latter species. A distribution map, based on available published and unpublished data for the two species, is presented.Keywords
