. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. SOUTH AFRICAN ASCIDIANS 13. Fig. 10. Aplidium monile sp. nov. A. Thorax. B. Post-abdomen. C. Thorax and abdomen of a brooding zooid. D. Larva. faces the first row of stigmata. Its upper rim has a simple pointed languet (Fig. 10A), sometimes with two small lateral lobes. The thoracic muscles are mostly longitudinal with thin fibres. The branchial sac has 10-11 rows of stigmata (Fig. 10A) that are not interrupted on the dorsal line. The abdomen is about the same length as the thorax. The posterior side of the stomach is half way along the gut loop. There are 18-20 longitudinal folds in a transverse section, some of which are cut or interrupted (Fig. 10A, C). The post-stomach has the usual annular swelling (Fig. 10A). The olive-shaped mid- intestine is separated from the rectal caeca by a constriction. The anus has two lobes and is mid-way along the thorax. The pyloric duct enters the stomach in the middle of its side. The post-abdomen may be very long. The ovary is far.
