Summary

From assemblages of Upper Jurassic organic-shelled microplankton from Dorset are described five new species of hystrichospheres. Of these, two are attributed to a new genus, Polystephanosphaera; one new species of the genus Hystrichosphaeridium, and two of the genus Baltisphaeridium are also described.
