). Around both siphons the tunic is raised in irregular finger-like papillae. Elsewhere the surface of the tunic is smooth. A trace of red pigment remained on some specimens. A thin vascular web in polygonal meshes can be seen in the transparent surface of the tunic. On the right side the muscular fibres are thin and regularly crossed. On the left side the musculature is limited to the anterior part of the body. The oral tentacles are not numerous: 16 to 20 large ones are distributed in two rings. The dorsal tubercle opens in a U near the neural ganglion (

A). The branchial sac does extend below the level of the gut. The digestive tract, in a double loop, occupies 1/3 of the left body side. The stomach is grooved. The long rectum obviously overpasses the level of the top of the primary gut loop. The gonads lie inside and over the intestinal loop.

B). Both siphons possess ocelli. More than 70 oral tentacles are inserted along a wide crest. The dorsal tubercle is far from the neural ganglion, at mid distance from the siphons. The dorsal tubercle opens in a U with slightly rolled horns. The branchial sac extends down to the body end, far behind the gut. The dorsal lamina reaches the bottom of the branchial sac below the oesophageal aperture. Sixty longitudinal vessels were counted on the right side of the branchial sac of a specimen
