Augener, 1913, p. 230, and 1924, p. 374. Monro, 1933, p. 35. Occurrence. St. 929, New Zealand (2). Specific characters. A smaller species than T. gigantea. The larger specimen measures 45 mm. by 2 mm. for 183 chaetigers. There is a pair of orange brown, trans- verse, equal bands in each segment for about the anterior third of the body. The head is bilobed, slightly incised behind. There are two pairs of large eyes. The median tentacle is about three times as long as the head and the laterals two-thirds of this. Upper tentacular cirrus about a third as long again as the median tentacle and the lower about half this. The dorsal cirri are alternating and have a violet colour. The longer are about equal to the breadth of the body, and the shorter about two-thirds of this. The pharynx has a crown of about 10 teeth surrounded by a circlet of 12 papillae. The bristles are bidentate. One of these specimens is in the chain phase. The stolon is not budded off from the last segment of the stock, but comes off from the 183rd chaetiger and leaves Fig. 19. Trypanosyllis taeniaeformis. the tail-end of the stock folded underneath the ventral ^^"t""^' ^'^^ °^ beginning of surface (Fig. 19). I cannot count the number of segments in this tail piece, but it is equal in length to the five preceding chaetigers. The stolon is clearly marked off both dorsally and ventrally from the stock. It is a female bud filled with eggs and has 35 chaetigers. There are no swimming bristles and apparently no ventral cirri. I cannot see a trace of c
