In preservative, colonies are thin white encrusting sheets with spicules crowded throughout. The stellate branchial apertures, lined with spicules, are evenly distributed over the surface and in some areas some small, pointed, spicule-filled surface papillae are scattered between the branchial apertures.

About eight stigmata are in each half row. Often a large yellow egg is against the posterior aspect of the ventrally flexed gut loop and the distal coil of the vas deferens extends tightly over the surface of the egg. The vas deferens coils eight times around the undivided testis. A strong retractor muscle projects from the top of the oesophageal neck. A branched test vessel with terminal ampullae projects from the concavity created by the ventral flexure of the distal end of the gut loop.</paragraph>
