. Bulletin of the British Museum (Natural History) Zoology. AFRICAN TURBELLARIANS 65 Stylochoplana simplex Localities. Cape Province, South Africa. Among rock in 3-A metres below LWST., Windmill Beach, False Bay (Holotype. ); on rocks off Rooi Els in 16-19 metres, False Bay, : on rock in 12-14 metres, Roman Rock, False Bay, ; on rock in 4-6 metres below LWST, Oakland Pt., False Bay; intertidal in cochlear zone, Froggy Pond, Description (Fig. 12). Delicate elongate forms said to be 'white and frilly' when active, measuring up to 9 mm long and 3 mm wide. Eyes disposed in two elongate groups alongside cerebral organ; cerebral eyes anterior to larger tentacular eyes in each cluster. Pharynx has shallow marginal folds in mid-third of body. Genital pores widely separated. Male copulatory complex immediately posterior to pharynx. Vasa deferentia unite to open into proximal end of fusiform seminal vesicle directed antero-dorsally. Ejaculatory duct short, directed posteriorly from seminal vesicle to open into an elongate-oval prostate lined with a shallow epithelium. The prostate opens directly into a relatively large, conical, unarmed penis-papilla lying in a relatively deep male antrum. Vagina narrow and thrown into a long anteriorly-directed loop, but not reaching the male complex. Vagina externa short; 'shell'-chamber long; vagina interna short, into the proximal end of which open the uterine canals. The features of S. simplex are the very simple copulatory complexes, the widely-separated genital pores, the elongate prostate and the absence of Lang's vesicle. >.
