Side en Række Spikler, der strække sig fra Tentakelens 
Grund til dens Spids. Disse Spikler ere trekantede, til-

Denne Søfjær nærmer sig med Hensyn til de faatal- 
lige Polyper, som hver Finne bærer, noget til Diibemia 
abyssicola varietas smaragdina*; men adskiller sig fra 
denne ikke alene ved Farven men fornemmelig derved, at 
Polypkroppen har kun en enkelt stor Spikel, imedens Dii- 
bena abyssicola varietas smaragdina er paa hver Side af 
Polypkroppen forsynet med en Reekke smaa Spikler.

and about 4”” long, including the tentacles, (fig. 4). In the 
integument of the body, a single spicule is seen; this is 
triangular, 0.368”” long, and 0.068”” thick towards both 
extremities, but somewhat narrower at the middle (fig. 
5, a. 6) The tentacles are about 2”” long and are fur- 
nished with pinules, and on their aboral side haye, a series 
of spicule, extending from the base of the tentacle to its 
point. These spicule are triangular, and acuminated at 
both extremities, and they measure 0.150”” in length, and 
0.020" in breadth, at the middle (figs. 5, b. 7).

Habitat. 
Station No. 252. Vestfjord, south of Skraaven. 170 
fathoms. Clay bottom, mixed with gravel. 
Specific Character. 
The stalk of the polyp is thin, round, erect. The fins 
are placed wide apart from each other, and each carries 2 
polyps. The body of the polyp, has a single, thick, long 
spicule in the middle. The calcareous plate quite con- 
_ceals the fin, and usually, has 7 long spicule, of which,

colour of the stalk, and also, of the fins, is yellowish-white.

tacles yellowish-white, with a deep brown stripe im the 
middle of the aboral surface. 
the external ones measure up to 2.5”” in length. 
In respect of the small number of polyps which each 
fin carries, this sea-pen approaches somewhat, to Diibemia 
abyssicola, varietas smaragdina!; but differs from it, not 
only in colour, but especially, im, that the polyp body, 
has only, one single large spicule, whilst Diibenia abyssicola, 
varietas smaragdina is furnished on each side of the polyp 
body, with a series of small spicule.

club. The rachis is 25”” long, 11”” broad at the middle,
