FIG. 6. — Hemicyclopora celtica n in On some "Hemicyclopora" Norman, 1894 and "Escharella" Gray, 1848 species (Bryozoa, Cheilostomatida) from the Atlantic-Mediterranean region. Re-examination of their generic status and description of new species and a new genus

FIG. 6. — Hemicyclopora celtica n. sp.: A, colony with clustered ovicells; B, small portion of a colony, note the occurrence of six, seven or eight spines in nonovicellate zooids, and 6 spines in ovicellate zooids; C, non-ovicellate and ovicellate zooids, all with six spines, ovicells associated with a distal autozooid; D, nonovicellate zooids with small marginal pores, subterminal orifice edged by six spines, prominent condyles and markedly convex proximal edge; E, F, non-ovicellate and ovicellate zooids, note the granular frontal shield with tiny marginal pores, the terminal orifice of the non-ovicellate zooid with eight prominent basal parts of spines, and ovicells with endooecium formed by the distal autozooid; G, H, frontal view of two orifices, with eight spines and a moderately convex proximal edge (G) and six spines and a triangular proximal edge (H); I, inner side of an orifice with smooth surface and basal pores of spines.
