In 5 (i) these are larger than in the other two, and might pass as small warts. 5 (i) is rather different from the other tvo, not only in sculpture but also in its web (which is longer than in the other two examples and is in addition equal in all its sectors save E) and in its wider body. The hectocotylus of 5 (i) and 10 (iv) are, however, both long (15 and 13-9 per cent respectively) and very alike. The calamus is acute and upstanding, the ligula rather shallower than in charcoti and crossed by a number of deep laminae, which resemble those of a 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; Great Britain.
