Zooids somewhat egg-shaped, slightly compressed laterally, the pedicel arising from the small end, which is the posterior ventral part of the body. Apertures but slightly prominent, the branchial near the dorsal side of the large end of the body; the atrial nearly opposite the origin of the pedicel. Both are lobed, but the lobes are not readily counted in the contracted preserved specimen. Nine.
