OCCURRENCE. — Pliocene: Calabria ( Neviani 1900 ). Pleistocene: Calabria ( Di Geronimo et al. 1997 ), Rhodes ( Moissette & Spjeldnaes 1995 ). Recent: eastern Atlantic and Mediterranean from the surface to 150 m (and down to 500 m in the Gulf of Gascony: Jullien & Calvet 1903 ). DESCRIPTION Cellariiform colony.Internodes comprising two alternating series of zooids. Gymnocyst smooth. Oval opesia occupying slightly more than half of the zooecial length with two large septula in the distal part of the opesial margin Five spine bases on the distal rim (three on the outer edge and two on the inner part), accompanied by one slightly larger scutal basis on the internal edge. The scutum itself, rarely preserved, is rather large and its proximal lobe is more developed. Prominent triangular lateral avicularia. When present, the frontal avicularia are small and always located near the internal distal part of the ovicells, which are rounded, smooth and exhibit a small proximal fenestra. Dorsal surface with small triangular vibracularia. REMARKS The number of spine bases is relatively constant, but one of them, on the distal rim, is occasionally lacking. Only two spines are observable on ovicellate zooids.
