Symplegma cf. brakenhielmi

#0151D; #1164, zooids about 3 mm long. Tunic clear, with well developed vascular system. In two examined zooids, the pyloric caecum is not obvious, only a curved connection long and tubular between the medial stomach bulge and beginning of intestinal loop. In another zooid, connections are visible between the beginning of the intestine and the distal intestine (before the rectum) with a bulge and possible third connection to the medial stomach bulge. In this colony the caecum is apparently embedded in the pyloric duct as figured by Monniot C. (1983b) and Monniot C. & Monniot F. (1997).

#3857, colorless in life except for red ring around the siphons. Eleven rows of stigmata. Nine stomach folds, posterior–most one tiny. Curved caecum and bilobed anus. No gonads.

#4611, pink and white in life, brown in formalin; 11 rows of stigmata. Stomach with about eight folds but difficult to count. Large curved caecum. No gonads.
