Fig. The occurrence of Cladocarpus bicuspis in the Northern Atlantic. In the hatched region the literature notes a scattered occurrence. Gen. Thecocarpus Nutting. Upright colonies with branched or unbranched main stem, the apophyses bearing unbranched hydrocladia with several hydrothecse. All sarcothecae immobile. The gonothecse are set in a corbula formed by a metamorphosed hydrocladium; the blades of the corbula, or ribs, have each a hydrotheca near its point of origin. Nutting (1900 p. 106) attaches primary importance to the question whether the stem is mono- siphonic, a character which, even in distinction of species, is of subordinate weight; a species such as Thecocarpus myriophyllum (Linne) occurs in northern seas not infrequently fertile with monosiphonic stem, while other colonies have a polysiphonic basal part; but it is really only in southern waters that strong colonies of this species are found with polysiphonic stems, at any rate a couple of feet high. This feature, then, is of little or no interest from the point of view of generic distinction; on.
