Specimens of dinoflagellate collected in tide pools along the Pacific coast of central and southern Japan are described as
a new species,Scrippsiella hexapraecingula Horiguchi et Chihara, of the Peridiniaceae (Class Dinophyceae). The plate formula is pp, x, 4′, 3a, 6″, 6c, 5‴, 2″" and,
5s, the same as that of other species ofScrippsiella, except in lacking one precingular plate. The genus must be emended, therefore, as having either six or seven precingular
plates.
This dinoflagellate migrates diurnally. In the morning motile cells are released from non-motile cells attached to the substrate
and in the evening the motile cells swim down to settle on the bottom of the tide pool. Attached non-motile cells form either
motile mono- or bispores. Sexual reproduction was not observed. 相似文献
