Description. The specimen measures 13 mm. by 2 mm. without the feet, and has about 45 chaetigers and 18 pairs of elytrophores. There is no colour. The head (Fig. 7, a) is broader than long, somewhat rounded in shape, and with two pairs of small eyes set rather far back and to the side.

The insertion of the lateral ten- tacles appears to be subterminal as in Halosydna, but of this I am not sure. The median tentacle is about of the same length as the long and rather slender palps, and it is longer than the lateral tentacles. The tentacular cirri are rather longer than the tentacles and there is a long ventral cirrus on the first foot. The elytrophore of the first foot is a cylindrical structure about half the length of the foot; the remaining elytrophores are conspicuous but not unusually 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.
