FIGURE 1. A–D: Helicosiphon biscoensis figured from BM (NH) 1930.10.8.2984, Discovery Expedition, St. 175, South Shetlands, 200 m: A–C: Tubes showing uncoiling. Ontogenetically, however, the earliest formed part of the tube is coiled as shown in Figs. A and C. That part of the tube is missing in the specimen figured in B. Note also the angular sides of the earlier uncoiled parts of the tube. D, Worm, showing the straightened body, which conforms to that of spirorbids (see also description); the attachment stalk for the brood-pouch to the thorax can be seen dorsally (brood pouch missing). E, Knightjonesia platyspira (Knight-Jones) 1978 showing its winged peduncle, figured from among paratypes in BM (NH) 1969.492, Marion Island, Prince Edward Islands, collected by A. F. Villiers, 1973; see Fig.2 for further details.
