Scale 0,5 mm. Reproductive system (Fig. 24) The ovotestis consists of numerous follicles which are united into an ovoid mass. The preampullary duct emerges from the anterior end of the ovotestis and expands into a highly convoluted, thickened ampulla. The ampulla narrows anteriorly and divides into the oviduct and vas deferens. The vas deferens is short, thick, and muscular, and expands into the massive penis
. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. SOUTH AFRICAN JANOLIDAE 25. Fig. 23. Bonisa nakaza gen. et sp. nov. Central nervous system. Scale 0,5 mm. Reproductive system (Fig. 24) The ovotestis consists of numerous follicles which are united into an ovoid mass. The preampullary duct emerges from the anterior end of the ovotestis and expands into a highly convoluted, thickened ampulla. The ampulla narrows anteriorly and divides into the oviduct and vas deferens. The vas deferens is short, thick, and muscular, and expands into the massive penis sac. The penial papilla is club-shaped and strongly corrugated. The oviduct is muscular and joins the large receptaculum seminis near its base. Traversing the base of the receptaculum seminis is a small, linear bursa copulatrix which joins the recepta- culum near the female gonopore. At the base of the receptaculum sac is a thick duct which connects it with the small albumen and membrane portions of the female gland mass. These glands join the massive mucous gland, which forms the bulk of the female gland mass. Egg mass (Fig. 25) The egg mass is about 20 to 30 mm high, consists of numerous convolu- tions and corresponds to type B (Hurst 1967). There are one or two eggs per capsule. The egg mass is frequently deposited on the finger-like projections of gorgonians. Natural history Bonisa nakaza is found in the shallow subtidal, at depths of 3 to 30 m on both the Atlantic and Indian Ocean coasts of the Cape Peninsula. It is.
