A few fragments come from the same station as that from which most of the type-material was collected. Unfortunately no complete specimen has yet been obtained, so that a precise specific diagnosis cannot be made. Among these fragments is one posterior end which shows five ante-anal achaetous segments and a pygidium (Fig. 30). The anus consists of a short cone surrounded by a circlet of about 15 short, more or less equal cirri, and , 1 • I • 1 n 11T Fig. 'JO.

Augener regards this species as close to Clymene minor (Arwidsson). The latter species has a very diflerent head with short nuchal organs, and the anterior border of the 4th chaetiger overlaps the 3rd chaetiger. More- over, the anterior ventral acicular bristles of the first three chaetigers are different from the hooks of the present species. Genus Maldane, Grube Head in the form of a convex keel. There is a border divided into three sections by a pair of deep lateral incisions. Nuchal organs short, more or less straight. Dorsal bristles of three kinds. Ventral uncini, absent from the ist chaetiger, begin on the 2nd. Anus dorsal. Pygidium in the form of an oval, bordered plate. The border is normally incised laterally and has the ventral region smooth or crenate. Maldane sarsi, Malmgren, var. antarctica, Arvvidsson.
