. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. 108 ANNALS OF THE SOUTH AFRICAN MUSEUM is situated in the middle of the interhepatic space. The gonopores are ventral to the first and second peduncles of the right anterior digestive branch. The body surface is covered by vivid mauve pigment. The rhinophores and oral tentacles are tipped with opaque white pigment. The ceratal peduncles are purple but the ceratal epidermis is translucent. The vermilion-red digestive gland does not entirely fill the lumen of the cerata. Each ceras has a subapical band
. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. 108 ANNALS OF THE SOUTH AFRICAN MUSEUM is situated in the middle of the interhepatic space. The gonopores are ventral to the first and second peduncles of the right anterior digestive branch. The body surface is covered by vivid mauve pigment. The rhinophores and oral tentacles are tipped with opaque white pigment. The ceratal peduncles are purple but the ceratal epidermis is translucent. The vermilion-red digestive gland does not entirely fill the lumen of the cerata. Each ceras has a subapical band of opaque white pigment. Internal morphology The buccal mass is small relative to the size of the animal. There are well-developed oral glands which extend into the anteriormost ceratal pedun- cle. The jaws (Fig. 2C) are thin and broadly ovoid with 5 to 6 rows of denticles on the masticatory border. The outer row contains 23 to 33 prominent denti- cles. The triseriate radula (Fig. 3) consists of 30 to 35 rows of teeth. The rachidian teeth are broad with a thick basal portion and 5 to 10 shallow to deeply incised denticles on each side of the slightly larger central cusp. The lateral teeth are triangular, basally arched and terminate in an acute apex. The number of denticles on the inner face of the laterals is variable. In some instances denticles may be absent, but there are commonly 7 to 12. The reproductive system (Fig. 2D) has a large, slightly convoluted ampulla. A postampullary duct of variable length gives rise to the duct of the receptaculum seminis. The large, pear-shaped receptaculum seminis lies ventral. Fig. 3. Flabellina funeka sp. nov.
