The free portion of the adcau- line wall is as a rule furnished with somewhat faintly marked transverse furrows. The opening margin has four low teeth and four triangular lid plates in the sinuses between them. The gonothecse proceed from the branches close under the base of the hydrothecse. They are oval, more or less furrowed transversely in the distal half, and have distally a narrow central opening with two diametrically opposite short broad 20o m. „ . 600 m. .„ 1000m. 2000m.
