[9 The cephalic lobe has a very deep incision (PI. 11, fig. 9); the latter readies so far that it almost divides the head in two halves. The frontal promi- nences are distinct and diverge somewhat No eyes are seen from above, but the usual two pairs are both present; the\ are ver\ feeble in colour; the hindmost pair is situated so caudally that it is hidden under the nuchal fold, and the two foremost eves are so ventrally situated that they cannot be seen unless the animal is turned round. None of the eyes is seen in the fieure. B 5- The unpaired tentacle is lacking but its basal joint, being very strong, shows that the former probably has been of considerable length. The two paired tentacles are relatively short and slender, in length about one third of the length of the palps. These latter are rather thick but their distal third is represented by a long and thin terminal filament. The palps are quite smooth while the tentacles are densely beset with long filiform papillae, the apex of which is somewhat extended. The tentacular cirri are provided with a rather long basal joint and are considerably longer than the palps; they are, like the tentacles, beset with papillae. The largest of the fragments consists — the head and buccal segment not counted — of 14 segments. The position of the elytrophores shows that the arrangement of the scales is that usual in the Polyuoids. The colour is dark violet. The pigment- ation does not extend to the cephalic lobe and its appendages. The parapodia are rather prominent; the neuropodial branch projects more than the notopodial, and the former is provided with a flab. The setae are long, especially the neuro- podial seta;, and they are present in considerable numbers (fig. 5). The dorsal cirri are entirely lacking, thus their length can- not be stated; I suppose them to be rather
