diameter) arising from common basal test. The stalked heads are unevenly distributed on the basal test (figure 2B) and are never crowded. The heads are clear and soft, and are clearly demarcated from the supporting stalks by their greater diameter and the softer consistency of the test. This demarcation is especially evident between heads and stalks in living specimens with inflated heads, but can also be seen in preserved specimens. The stalks and basal tunic are firm and opaque and usually are covered by fine sediment, sparse sand grains and epibionts. Inner layers of the test may contain scattered minute sand grains but generally are free from embedded matter. The largest colony photographed

In preserved material contracted zooids are mostly located in the heads of the colony, and only occasionally abdomina extend down the stalk. Zooids are parallel to each other and open on the upper surface of the heads. Occasionally atrial siphons of two or three zooids open close to each other forming a rudimentary system, but generally these systems were not detected, and may not always be present.

long. Atrial and branchial siphons are prominent, muscular, with six-lobed margins around each aperture. Longitudinal muscles are in 10–12 separate, well spaced narrow bands on each side of the thorax. These converge to form a wide band along each side of the mid-ventral line of the abdomen to the posterior end of the zooid. Numerous transverse thoracic muscles are much thinner than the longitudinal muscles and are discernible only after staining. Branchial tentacles are relatively numerous (about 20) and are arranged in three distinct circles. Stigmata are in three rows, the anterior row is straight at its dorsal end (not curved anteriorly as in some other species). About 12–14 stigmata are in each half row, but these were counted only in a few less contracted zooids. The esophagus is long, as is characteristic of

. A small slightly asymmetrical stomach is at the posterior end of the abdomen, its wall generally is smooth or it has shallow, irregular, longitudinal creases that appear to be a result of contraction or collapse. An oval posterior stomach and mid-intestine were observed in some zooids. Neither gastric vesicle nor pyloric gland were detected. Large oval male follicles fill the posterior end of the abdomen, about 15 being counted in one zooid. Some zooids have one or two large embryos or larvae in the atrial cavity. Larvae are large, the trunk being

Adhesive organs alternate with three thick-walled median ampullae. Also one shallow lateral ampulla sometimes is discernible.
