I shall deal separately with their distribution in what follows, and at the same time give some particulars of their quantitative occur- rence. Part of the material is still incompletely examined. The difficult species of Peridinium in particular, and of a few other genera, will require a separate monograph for their special treatment; we have secured immense numbers of these forms. In other respects our observations practically confirm the views regarding the distribution of species that we owe chiefly to Cleve. I shall .now give a preliminary description of the character of the plankton along our route, founded upon an examination of 2 A
