long. Zooids are relatively large and open all around the transparent, globular or conical head. In the newly recorded specimens zooids are contracted and the two anterior siphons with their apertures constricted into transverse openings are conspicuous and turned slightly away from one another. The top of the thorax (around the apertures) is flattened or slightly concave. About 10 fine longitudinal muscles are on each side of the thorax and extend down onto the abdomen and the posterior abdominal stolons, which are long and crowded extending parallel to one another down the length of the stalk. The branchial sac has eight long rows of about 3040 long narrow stigmata in each half row although stigmata are shorter in the posterior rows. The interstigmatal bars are flattened into wide membranes. The gut loop is narrow, vertical and relatively short, being only about twice the length of the thorax and the anus opens about halfway up the branchial sac. Gonads were not detected in these specimens although previously they have been observed in the gut loop. A developmental sequence of up to eight embryos to tailed larvae is in the distal part of the oviduct. In contracted zooids this part of the oviduct, with the embryos it contains, forms a horizontal loop crossing the dorsal line from the left to the right and projects out like a collar around the top of the oesophageal neck. The most advanced larvae are released into the right peribranchial cavity. The larvae are spherical with four rows of small stigmata and an ocellus and otolith. Three triradially arranged deeply invaginated tubular adhesive organs are at the anterior end of the larval trunk.
