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 gonothecas proceed from the branches close under tlie base of the hydrothecic. They are oval, more or less furrowed transversely in the distal half, and have distally a narrow central opening witl) two diametrically opposite short broad 100 m. s000m. 600 m. .^ 1000 m. Fig. LV.
