. Natural history. Geology; Zoology; Botany. cc. u Fig. 27.—Cuthonella paradoxa—A Tooth ; a Prom above ; b From below. Length, 11 mm., breadth, 8 mm., height, 4'3 mm. The pointed tail, as distinct from the dorsum, is 2 • 3 mm. long. The oral tentacles are 2 mm. long, and point straight right and left. The rhino- phores are 3 mm. long, stout, bent forwards and bear transverse rings, but it is not clear if these rings are natural or the result of contractions. On the left side is a single line of twelve cerata along the dorsal margin, none more than 1 mm. high, conical, with gaps between them, so that the line is probably not complete. Within this line there remains still attached a single very large papilla about 7 mm. long and rather bent. It is behind and slightly to the left of the anal papilla. On the right-hand side is a similar line of twelve cerata, mostly rather larger. Under the first three of them is a second row of three very small ones. In the bottle are seven detached cerata measuring 7, 5, 5, 4, 4, 3, 2 mm. respectively. The anal papilla is dorsal, set far back (7 mm. from anterior end) and slightly to the right of the median line. The genital orifices are 4 mm. from the anterior end, rather high up on the side. The anterior end of the body forms a hdftd over the mouth which, as preserved, is ventral. The foot is rounded in front, thickened at the margin and slightly 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 National Antarctic Expedition, 1907-1904; Fletcher, Lazarus, Sir 1854-1921; Bell, F.
