The atrial aperture is terminal and the oral siphon on a side. The muscles of the siphons are relatively weak compared to the strong bundles of fibres running on each side of the dorsal line. The branchial sac is wide and stretched to a pouch into the peduncle. The branchial tissue (

The anus has pointed lobes. The testis vesicles overlap the whole intestinal loop. The ovary is linear inside the loop.
