Abstract
Fragilidium fissile is a new species of this rare genus. It somewhat resemblesF. subglobosum. It differs from the latter in having a slot and a pore in the first apical plate 1′ (the nomenclature of dinoflagellate plate designation follows the Kofoid system). Both species are also distinguishable by noticeable differences in Po, 1″″ and 1‴.Peridinium tyrrhenicum is a small species differing from all the other known species ofPeridinium in its shape, apical channel and several plates, especially some of the sulcal components.Alexandrium foedum somewhat resemblesA. balechii, but it differs from the latter in that its width is greater than its length, and in the characters of all the main sulcal plates. The above listed species were found in a sample from the Tyrrhenian Sea. The fourth species,Alexandrium andersoni, is a small dinoflagellate obtained in coastal waters off Cape Cod. It differs from all the other species of the minutum group in the very typical shapes of both the 6″ and the S. s.Pentapharsodinium daleii Indelicato and Loeblich is transferred toPeridinium.
