Stations. TR 7 ( MNHNAbout MNHN A 3 DISAbout DIS 102). TA 60 ( MNHNAbout MNHN A 3 DISAbout DIS 103).

The colony of st. TR 7 is made of 2 pedunculate lobes erect and close together on the substrate; the largest has a head 2.5cm wide on a stem 2.5 cm long. Circular systems occupy the whole colourless head. The peduncle wears some epibionts. The tunic is hard, cartilaginous. The thoraces ( Fig. 27 AView FIGURE 27. A) have a large languet. The brancial sac has parastigmatic vessels. The gut loop is widely opened, the stomach is long with longitudinal internal folds ( Fig. 27 AView FIGURE 27. A). A large pyloric ampulla lies in the gut loop. The gonads hang in a pouch behind the abdomen ( Fig. 27 AView FIGURE 27. A). Only immature larvae are present free in the tunic; an empty incubatory pouch can be seen in some zooids.

Another colony, 5cm long with a head 2.7cm wide, collected in st. TA 60 has the same aspect but is of a deep blue in formalin. All anatomic characters are the same as in colourless sample. The brooding pouch contains one larva. This sample is provisionally placed in the same species.
