Cladocarpus bicuspis from "Ingolf" St 98. a Basal part of a hydrocladium with its phylaetogonium (X 40). b Side view of a hydrotheca (X 60). - c Front view of a hydrotheca (X 60). more strongly developed in Cladocarpus bicuspis (fig.

The strong S-shaped septum is suggestive of Cladocarpus sigiua Allmann; on the other hand, the inner longitudinal abcladial keel seems to be without parallel in the genus. The phylactogonia are dichotomically branched, the ramification does not always take place once only, as in the one shown (fig. XL-VIII a), but as a rule two or three times, so that we have three or four terminal branches. The gonothecse shown by G. O. Sars (1874 pi. 2, fig. 8) are not yet fully grown. The full-grown gonotheca presents the same typical appearance as the remaining north- ern Cladocarpus species, with a much more strongly developed upper lip domed out over the open- ing; it is here as strongly developed as in Cladocarpus Diana. Cladocarpus bicuspis is altogether a rare species in the regions investigated (fig. XLJX) and as it does not seem to have been found at all elsewhere, its true habitat is still a matter of doubt. In the northern waters, the species belongs to the typical visitors from the warmer atlantic waters, being previously known only from between Stavanger and Trondhjem Fjord on the west coast of.
