Central nervous system (Fig. 6A) All of the ganglia are coalesced into a circum-oesophageal nerve ring. The cerebral and pleural ganglia are entirely fused. Extending anteriorly from the cerebro-pleural ganglia are the rhinophoral ganglia, each of which gives rise to three nerves. The eyes are situated at the postero-lateral base of the cerebro- pleural ganglia. The pedal ganglia are joined by a pair of elongate commissures. The paired statocysts are situated at the antero-medial ends of the pedal ganglia. Reproductive system (Fig. 6B) The ovotestis consists of numerous lobes, each with separate male and female acini. The preampullary duct is short and expands abruptly into the coiled ampulla. The ampulla divides into a short oviduct that enters the albumen gland and the vas deferens. The albumen gland is small and ovoid. The adjacent membrane gland consists of two lobes. The largest portion of the female gland mass is the mucous gland. The spherical receptaculum seminis joins the oviduct near its entrance into the albumen gland by means of a narrow, elongate duct. The vas deferens expands into a prostatic portion that traverses the dorsal surface of the penis. From there it extends ventrally and ultimately enters the ental portion of the penis. The penial papilla is emarginate at its Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
