). Muscular external vagina, or vagina bulbosa, lined with cuboidal epithelium with fringe-like extensions. Vagina bulbosa narrows distally, then extends dorsally or anteriorly towards male copulatory system before reaching internal vagina. Internal vagina turns posteriorly and runs dorsally to posterior end. Oviducts lead separately into common receptacle at proximal end of internal vagina. Numerous shell and cement glands open in region surrounding both vaginas. After receiving oviducts, vagina continues into enlarged Lang’s vesicle that extends posteriorly, sometimes reaching posterior end of animal (

Externally, both have an elongated body with pale ground colour, two clusters of both tentacular and cerebral eyes and lack tentacles. They also possess a ruffled pharynx that occupies the middle third of the body and a copulatory system that begins posterior to the pharynx.
