Charts showing the distribution of each of the principal species, and also the total diatoms, are also given (Figs. 12-17) in an attempt to build up a picture of the conditions over the whole area. It may be men- tioned that most of the lines consisted of eight stations worked at approximately lo-mile intervals. The main features of the Larsen line (Table II, Figs. 4, 5) were the almost complete absence of diatoms at the inshore stations, where the dinoflagellates Peridinium ant- arcticum and Ceratiumpentagonum were dominant, and the relative abundance of diatoms, principally Corethron valdiviae in the spineless chain form, and Thalas- siothrix antorctica at the next two stations. The outermost stations on this line (Sts. 357 and 358) were perforce worked much later than the others when conditions were obviously different. The temperatures were higher, and the two large dinoflagellates.
