Kroppens Hud sees en enkelt Spikel, der er trekantet, 0,368"""
lang og 0,068’"’" tyk mod begge Ender, men noget smalere
paa Midten, Fig. 5, a. 6. Tentaklerne, omtrent 2’"’" lange,
ere forsynede med Pinnuler og have paa deres aborale
Side en Række Spikier, der strække sig fra Tentakelens
Grund til dens Spids. Disse Spikier ere trekantede,
tilspidsede i begge Ender, 0,150""" lange, 0,020’""’ brede paa
Midten, Fig. 5, b. 7.

Stokken gulhvid, Sarcosomaet halvt gjennemsigtigt.

omgiver Kalkpladen, gulhvid. Polypkroppen mørk

Artskarakter.
Polypstokken tynd, rund, stiv. Finnerne staa vidt fra
hverandre, bærende hver 2 Polyper. Polypkroppen har
paa Midten en enkelt, tyk og lang Spikel. Kalkpladen
skjuler ganske Finnen, har i Regelen 7 lange (Spilder,
hvoraf de yderste ere indtil 2,5""" lange. Stokkens Farve,
ligesom Finnernes, gulhvid. Polypkroppen mørk
kastaniebrun. Tentaklerne gulhvide med en intens brun Sribe paa
Midten af den aborale Flade.
Denne Søfjær nærmer sig med Hensyn til de
faatallige Polyper, som hver Finne bærer, noget til Dübenia
abyssicöla varietas smaragdina1; men adskiller sig fra
denne ikke alene vecl Farven men fornemmelig derved, at
Polypkroppen har kun en enkelt stor Spikel, imedens
Dübenia abyssicöla raridas smaragdina er paa hver Side af
Polypkroppen forsynet med en Række smaa Spilder.
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
furnished with pinules, and on their aboral side have, a series
of spiculæ, extending from the base of the tentacle to its
point. These spiculæ 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).
Colour.
The stalk is yellowish-white. The sarcosoma is
senii-translucent. The rudimentary fins, and also, the membrane
which surrounds the calcareous plate, is yellowish-white.
The body of the polyp, is dark chestnut-brown. The
tentacles, yellowish-white, with a deep brown stripe in the
middle of tin* aboral surface.
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
conceals the fin, and usually, has 7 long spiculæ, of which,
the external ones measure up to 2.5""" in length. The
colour of the stalk, and also, of the fins, is yellowish-white.
The body of the polyps, dark chestnut-brown. The
tentacles yellowish-white, with a deep brown stripe in the
middle of the aboral surface.
In respect of the small number of polyps which each
fin carries, this sea-pen approaches somewhat, to Dübenia
abyssicöla, varietas smaragdina1; but differs from it, not
only in colour, but especially, in, that the polyp body,
has only, one single large spicule, whilst Dübenia abyssicöla,
varidas smaragdina is furnished on each side of the polyp
body, with a series of small spiculæ.
