"Cyclicopora polaris sp. nov.

(Pl. III, figs. 5a-f)

This occurs both adnate and bilaminate, from the same locality. The zooecia in the bilaminate specimen are oblong, slightly raised, surface smooth, with a row of pores round the border, from which there are irregular suture-like lines and a similar median line. In the adnate specimen the zooecia are broader, and may be called subhexagonal to broadly ovate, and above the oral aperture there are 4 spines.

The oral aperture is wide, nearly round, with a very wide sinus. In some cases there are two small projections of the calcareous wall over the ends of the sinus. The operculum has a broad thickened border, reminding us of the opercula of some Membranipora, such as M. tenuirostris Hincks. The distal rosette plates are small and numerous, placed near the basal wall. The lateral plates are very large, with several pores, and are nearer to the frontal wall than to the basal. There usually seem to be four lateral plates.

This species recalls the Arctic Pseudoflustra palmata Sars, and in the present form the rosette plates more nearly approach to the Flustra type than they do in the Arctic species. The entirely separable operculum brings it near to species named Schizoporella.
