of spicate fusees, foliaceous sub-clavates, and quadruplets. The 

 tentacles are about half the length of the body, and are, on their 

 aboral side, right out to the extremity, furnished, with transversal, 

 almost flat, spicate spicules. The spicules of the basal part consist of 

 clavates, sub-clavates, bi-stellates, fusees, rollers, and quadruplets. The 

 stem is less rich in spicules, but the branches, and the branchlets, 

 are richly furnished with them, in the form of fusees, quadruplets, 

 twins, and rollers. Colour: yellow. 



Habitat. Four specimens. 64° 36' N. L., 10° 22' W. L. 

 Depth 547 m. Temperature, 0,3 C. Bottom; Dark-grey clay. 



Duva glacialis n. sp. 



The Zoanthodem measures up to 70 mm in height. The 

 stem, at the base, measures 70 mm in circumference; is cylin- 

 drical, grooved, and diminishes rather abruptly in thickness. The 

 basal part membranaceously dilated. Immediately above the basal 

 part a few, thin, short branches carrying several polyps occur. The 

 main branches commence farther up the stem, are thick ami 

 placed farther apart from each other; at a short distance from the 

 stem, they ramify into 2, and each of these, again, ramifies into 

 3 — 4 branchlets, each of which carries 4 — 6 polyps. These are 

 cylindrical, and 5 mm in length. The anterior body is somewhat 

 dilated. The posterior body narrow, rather elongated. The body 

 of the polyps, and the 4 dorsal tentacles, furnished with spicules. 

 The entire Zoanthodem rich in spicules. In the basal part, the 

 spicules appear, principally, in the form of protuberating beams, 

 between which, columns, sub-clavates, quadruplets, and a few 

 fusees occur. In the lower half-part of the stem, bi-stellates, sub- 

 clavates, and fusees are the most frequent; and in the other half- 

 part, quadruplets are more frequent than in any other part of the 

 colony. In the polyps, the fusi-form is the most frequent. Colour: 

 pale-yellow, shading a little towards red. 



Habitat. One largish, and one smaller specimen. 68° 21' 

 N. L., 10° 40' E. L. Depth, 836 m. Temperature, 0,7 C. Bot- 

 tom; Sabulous clay.
