): The nerve fiber layer of the proboscis is thickened middorsally along the shallow middorsal groove. The circular muscle fiber layer is quite conspicuous, being 4 or 5 fibers in thickness. Longitudinal muscle fibers are arranged concentrically, forming 8 or 9 rings. The proboscis cavity is narrow, extending nearly to the tip of the proboscis, completely filled anterior to the proboscis complex with irregular, granulated cells (connective tissue elements) limited all around by a layer of circular fibers. There is no dorsal septum and the ventral one extends only up to the ventral blind lumen of the stomochord (

The complete filling up of the proboscis coelom by irregular granulated cells, the possession of a dorsal glomerulus and the complete separation of the perihaemal cavities through their entire length are characteristic of this species of
