The rest of the distinguishing characters fall under what has been earlier stated. Corymorpha groenlandica is a typical form characteristic of the great deep of the cold area. It proves to be widely distributed, from Spitzbergen to the Faroe Islands, and from Norway to Green- land. It has also been recorded from Davis Strait. In the seas far to the north it rises to more shallow waters. Thus it has been recorded near Spitzbergen at the depth of only 45 metres (Broch 1909). A remarkable geographical exception is formed by the occurrence of the species in the deeper Atlantic. 20om. 6 oo n. ._ 1000 m. i 2000m. Text-fig. I.

But a great deal may be said in favour of the notion that we have here in hand a relict form, which has been able to accommodate itself to the altered circumstances in the same way as Tubularia regalis Boeck and Stegopoma plicatile (M. Sars) which are rather frequently occurring on or at the Lophohelia reefs of the 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 Ingolf (Cruiser); Danish Ingolf-Expedition (1895-1896).
