"Cellarinella nodulata sp. nov.

(Pl. VIII, figs. 6a-c)

The specimen from 623 was at first thought to be the nodulated variety of Cellarinella foveolata nov., but there are important differences.

The zoarium is erect, about 35mm long and about 5mm wide, it is somewhat compressed, and at irregular intervals contracts, forming nodulations ; it is attached at the base by

chitinous radicles. Similar nodulations sometimes occur in Cellarinella foveolata nov. and according to BIDENKAP in both Myriozoum coarctum Sars and M. subgracile d'Orb.

The zooecia have large pits, distributed over the surface, and the outlines of the

zooecia are not distinguishable ; below the aperture there is a long striated projecting median mucro, much like that of Lepralia ocellata Hincks. At one side of the aperture is a triangular avicularium with broad triangular mandible.

Lepralia pachycera Reuss (Olig. Gaas, p. 471,pl. IV, fig. 1) has a similarly shaped mucro and there are other species with strong mucros, as L. ceratomorpha Rss., L. monoceros Rss.

There are no polypides, but there are buds and the remains of polypides. The muscles for closing the aperture are similar to those of C. foveolata.
