The siphons are close to each other with sharp spinules. The internal layer of the siphons remained yellow in formalin. Extracted from the tunic the body wall is colourless and thin with a weak musculature. Its internal layer is spotted with cells highly stainable (

A,B). The stomach occupies a large part of the ascending limb and is not well separated from the intestine. Twelve to 14 folds can be seen in transparency on the mesial side. A wide bundle links the stomach to the intestine. The rectum does not draw a secondary loop. The edge of the anus is scalloped. The whole gut is loosely attached to the body wall and to the branchial sac by thin straps. There are 2 gonads on each side, each a long ovary with a basal massive testis in a cap (
