D, 16): Ovotestis sac-shaped, occupying dorsal surface of upper whorls, adjacent to but not intertwined with digestive gland. Hermaphrodite duct straight, seminal vesicle occupying upper portion; albumen and oviductal glands pink in formalin-preserved specimens. Seminal receptacle small, bean shaped, brown in formalin-preserved specimens, with moderately long, coiled duct leading to carrefour. Spermoviduct dividing immediately below carrefour, forming morphologically indistinguishable muscular tubes lacking any glandular or other differentiation (these presumably correspond to oviduct and vas deferens), which run parallel to each other through the body wall and reunite near the genital atrium. Reunited spermoviduct continuing via a narrow duct, opening directly into the genital atrium. Two accessory sperm transfer structures (ASTSs) opening to genital atrium; one club-shaped organ with internal duct connected to bilobed gland, exterior surface of structure covered with closely-packed papillae which appear to produce glandular products. Large, spherical prostatic gland positioned on left anterior of reproductive complex; long, muscular duct with thick muscular bulb leading to second ASTS at genital atrium. Second ASTS composed of elongate tube lying within an external tube, lined with dense, cuticular, spinous microsculpture. Both ASTSs have retractor muscles.

was limited by availability of specimens. The only material available was preserved in formalin for a considerable time. Dissection, whole mount and serial histological sectioning were all used to examine the morphology of this species. However, it still remains to examine fresh or recently preserved material to confirm the findings of this study. The anatomical arrangement of the reproductive system suggests that sperm and ova are conducted via separate ducts which reunite at the genital atrium. The method of sperm transfer may involve either of the copulatory structures in the genital atrium, one or both of which presumably function as an intromittent organ.
