). The atrial aperture is surrounded by a crest of papillae interrupted dorsally. In the ventral region, the papillae of the crest are thicker and attached by their sides, creating a sort of stout lamella. There are no papillae in the mid-ventral region nor in any other region of the body (

). There are 32 oral tentacles, with ramifications of the one order, disposed in a circle. Bigger tentacles with wide bases are distributed interspaced with smaller and thinner tentacles. Some of the bases of the bigger tentacles are so wide that they extend beyond the line of insertion towards the oral aperture. There is no oral velum. The dorsal tubercle has a “C” shape. The pre-pharyngeal band is simple. It makes a pronounced V around the dorsal tubercle. The dorsal lamina is composed of 20 triangular languets. Strong muscle fibers form a gridded network over the mantle. The branchial sac has six folds on each side. The branchial formula for the left side is:

There is a short esophagus that connects with a small stomach, which is covered by two rows of hepatic diverticula. The intestine is long and thick. The border of the anus has multiple lobes. A short atrial velum was observed. There are two gonads on each side of the body. On the left side, the posterior gonad is located inside the gut-loop, while the anterior gonad is located antero-dorsal to the gut-loop. Both right gonads are located parallel to the endostyle, in one line, one after another. The anterior gonads on both sides of the body have two lobes, while the ventral gonads have only one (

The authors originally described two populations based on the shape of the crest: one group with a continuous crest and the other with a crest composed of separate papillae. However, subsequent samples showed the existence of intermediate forms (Monniot C. & Monniot F. 1982). The number of branchial folds may also vary in
