Davis Strait. 700 - From Danmark Strait one capture is present, namely: 64°42' N. L. 27°43' W. L. Further, one capture from the tract south west of the Faroe Islands, namely: 6i°o8' N. h. 9°28' W. L. 820 in. We here have a case like that of Aphrodite aculeata neither Latmonia filicornis has hitherto been known from Greenland waters, and now it suddenly comes to light from a lot of different local- ities in Davis Strait. All these localities are situated on rather deep water and all of them have the bottom-temperature positive. Lastmonice appears to be much more abundant in these localities than Aphrodite, a far greater number of the former lias been taken. I shall only say that from the above St. 32 of the Iugolf-Expedition more than a hundred specimens are present.. Polynoidae. As to the arrangement and classification of the PolynoicUe in the present paper I should wish to remark the following. Concerning the limitation of the genus Harmothoc I am following Levinsen in comprising under this genus all the species provided with the typical, well-known, sword-shaped notopodial setae. At present there are 110 essential difficulties in this arrangement — at any rate when it is a question of northern forms exclusively — and as long as thorough researches, based upon anatomical investigations concerning the whole group of Polynoi'ds are lacking, there is no possibility for a systematic arrangement based on the principles of natural relationship. Nor do but two authors appear to be able to agree as to this question at present. Since the completion of my manuscript a new paper by Erik Bergstrom 1916 dealing with the Polynoids from the Swedish ant
