They have a robust cylindrical branchial siphon with six pointed lobes around the aperture. A pronounced bifid lip projects from the anterior rim of the atrial opening. An oval lateral organ is on each side of the thorax. About eight stigmata are in the anterior row of the branchial sac, but the exact number is obscured by contraction. A robust retractor muscle projects from the oesophageal neck. The vas deferens coils eight times around four or five testis follicles. Embryos are being incubated in the basal test. The large larval trunk (1.0 mm long) has the tail wound three-quarters of the way around it. Three anteromedian adhesive organs are surrounded by a circle of 30 ectodermal ampullae. An otolith and ocellus are present, and the outer surface of the larval test is ornamented with fine striations. Other organs were not detected although the size of the trunk suggests that blastozooids could be present.</paragraph>
