DESCRIPTION
The colonies are very dark inside but somewhat lighter externally, due to the spicules in the superficial layer ( Fig. 120E View FIG ). There is abundant mucus in the cloacal cavity. The colony is thick and not brittle. The zooids are black. The oral siphon is short. The cloacal aperture is wide with a very large bilobed languet in zooids near the common cloacal aperture but smaller elsewhere. The retractor muscle parts from the upper part of the oesophageal peduncle. The abdomen has about the same size as the thorax. The single testis follicle is large, flat and covered by the coiled sperm duct. The oocyte is large and protruding. The larvae are black with three short, stout adhesive papillae and a crown of numerous, joined digitiform ampullae.
REMARKS
All characters correspond well to previous descriptions, and the spherical spicules with many short, pointed rays are also similar. This species is widely distributed; it occurs as well in Senegal, from which it was described, and in the Indian Ocean and the western Pacific Ocean.
