. The Danish Ingolf-Expedition. Scientific expeditions; Arctic Ocean. 88 PENNATULIDA. given') in Grieg's review (Berg. Mus.

From the Fseroe Islands, Iceland, and Greenland no Pennatulid was hitherto known (apart from Umbellula lindahli and the statement concerning Pavonaria finmarchica, see p. 39). It has now been proved that several species are found in the depths of the sea near these countries, also a few in more shallow water. From the banks at the Fseroes are now known Pennatula grandis (numerous) and Halipteris christii. From more shallow water (less than 100 fathoms) at Iceland (the Vestman Islands) are now known: Pennatula pliosphorca (var. Candida), Virgularia mirabilis, Virg. cladiscus, and Stylatula (Dubenia) elegans. From the fjords of the Fseroes and Iceland —in contrast to those of Norway - - sea-pens are now as little known as hitherto. This holds good also with regard to the western fjords of Greenland. From the sea between Greenland and the American polar islands only Umbellula lindahlii was previously known; this species has now been found again farther south, in the Davis Straits, and to it are further to be added Pennatula aculeata, Penn. prolifera, Authoptilum grandipZorum, Distichoptihim gracile, and Kophobelemnon stelliferum, so that for the present six species of sea-pens are known as «West-Greenland: species. From East-Greenland only one species, Umbellula encrinus, is known, and only from its northern part. The fact that the species upon the whole divide into an Atlantic and an Arctic territory seems to me, however, of greater interest than the reference of the species found to the fauna of the nearest land.
