Note. This genus has a distinct connection with the preceding sub-genus of Do- 



cidium, from which and from certain species of Penium also (cfr Lund. Desm. Suec. p. 7), 



it dififers only in the absence of 'apical locelli' — while from Docidium (E Oontidium) it 



differs also in the absence of a marked suture, and decided constriction. There are argu-
