The coast currents will probably also carry the neritic organisms from one place to another. The neritic species that are found in a place, can therefore very well be of foreign origin ; but it seems to be a rule that they do not drift long distances, and in any case, the local, endogenetic forms in each place will be in the majority as compared with the allo- genetic coast forms. I. Taenio-plankton, or Arctic Neritic Plankton, as it occurs in Nordland, is a pure diatom-plankton. It consists of... the following neritic diatoms, which are also found on the coasts of Green- land and Spitsbergen: Achnanthes taniata Biddulphia anrita Chcetoceras contort um — debile — diadema — furcellatum * — sociale Digitized by Google - 58 - Uuetoceras teres Coscinodiscus polychordus Fragilaria oceanica * Lauderia fragilis * Navicula Fanh0ffenii''^ Podosira glacialis Skeletonema costaium Thalassiosira gravida — hyalina * — Nordenski0ldii This community is found on the coast of Nordland especially in April, but only close to the coast.
