The individuals are almost separated along their whole length only united at their base ( Fig. 28 A View FIGURE 28. A ). Up to twenty specimens can be grouped in a single mass. The tunic is smooth and naked, ochre in formalin. Both siphons are apical; epibionts are often settled at the base of the body. The individuals of a same group have not the same development stage and the basal part of the body which does not contains organs is more or less long. The largest individuals reach 5.5cm in length. The body wall is opaque; of an orange colour more reddish on the siphons. The internal side of the body wall is covered with leaf-shaped endocarps ( Fig. 29 View FIGURE 29 A). The branchial tissue is thin with 4 folds on each side ( Fig. 29 View FIGURE 29 B). The gut loop is closed with a short stomach internally folded and a long rectum ending in a lobed anus. Several specimens were eviscerated. An average of 11 elongated polycarps is lined on each side of the body. The atrial siphon has numerous thread-like processes at the base of the lining.

This species is only recorded from the western Indian Ocean from Djibouti to Mozambique and Madagascar.
