The frontal wall of the kenozooecium, which forms the ectooecium, is wholly uncalcified and col- lapses into wrinkles on drying (Fig. 26 A), the space between the entooecium and the walls of the kenozooecium then forming the " depression " mentioned by MacGillivray. A longitudinal wrinkle may sometimes give the impression of a keel, but the ovicell is not Fig. 26. A. Farciminaria simple

Farciminellum antarcticum Australian Antarctic Expedition, St. 4, off Adelie Land. Both drawn from dry specimens seen by reflected light. X. slightly crushed ovicell showing splitting along median line. This species has hitherto been known from more or less fragmentary material. The present specimens show that the colonies attain a considerable size. The material from St. TN 338 comprises six clumps. Plate VIII shows one of the smallest, the largest being 22 cm. long and profusely branched. The proximal branches are enveloped in a thick mass of rootlets so that the colonies appear to originate in a branching Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Institute of Oceanographic Sciences (Great Britain); National Institute of Oceanography of Great Britain; Great Britain.
