Cellernes ydre Væg er rigt udstyret med større og 
mindre, trekantede Spikler, hvoraf de fleste have en tegl- 
stensrød Farve. Ligesom Spiklerne ere forskjellige i Stor- 
relse, saaledes ere de ogsaa noget forskjellige i Form. Der 
er i Regelen 3 Størrelser; de mindste ere 0,142”” lange, 
0,016”” brede; de mellemste ere 0,268”” lange, 0,018"” 
brede, og de største ere 0,893”” lange, 0,045”” brede, Fig.

ler med mere eller mindre tilspidsede Ender og saadanne, 
der have afstumpede, takkede Ender. — Spiklerne ligge tæt 
paa hinanden og ere ordnede som paa Protoptilum carinatum. 
Cellernes indre Væg, der er fastvoxet, er saagodtsom uden 
Spikler. 
Zooiderne have en aflang Mund, ere dekkede af flere 
Bundter Spikler, som ere trekantede, fordetmeste teglstens- 
røde med tilspidsede Ender; de ere 1 rigere Mengde 
tilstede end paa nogen af de foregaaende 3 Arter, og ere 
meget lange, omtrent som de længste paa Cellerne, hvorved 
Rachis faar et paa Spikler meget rigt Udseende. 
I det føromtalte, nøgne Belte langs Ventralfladen 
ligge Spiklerne enkeltvis, adskilte fra hinanden og i afbrudte

Sarcosomaet er tyndt, halvt gjennemsigtigt og spikel-

Axen er rund, ender foroven i en liden Konus, der 
er blottet for Sarcosomaf; nedentil ender den haarfint i en 
Anse. Hvorvidt Axen strækker sig lige ned i Bunden af 
den bulbøse Del, eller den bøier af længere oppe, kan ikke 
afejores, da hele Stilkens Sarcosoma var afrevet ved Skraben.

deres Tentakler ere endnu blegere.

undulating line. On the sides of this stripe, slightly diagonal 
series of zooids are seen (fig. 3, a), 2—3 in each series; 
these abut upon the zooids dispersed between the cellular 
series (fig. 4, a). 
The exterior wall of the cells is richly supplied with 
larger and smaller triangular spicules, of which, the greater 
number have a brick-red colour. Just, as the spicules are 
variable in size, are they, also, somewhat variable in form. 
There are usually 3 sizes of these, the smallest measure 
0.142”” long, and 0.016”” broad; the median measure, 
0.2687” long, and 0.018”” broad; and the largest measure, 
0.893”” long, and 0.045” broad (fig. 6). With respect to 
the form of the spicules; this varies between spiculæ with

covered by several bundles of spiculæ of triangular shape;

than in any of the 3 preceding species, and they are very 
long, almost as long as, the longest pertaining to the cells; 
and they impart to the rachis, a rich appearance of spic- 
ular wealth. 
In the unoccupied stripe previously spoken of, the 
spicules are placed, singly, along the ventral surface, separ- 
ated by intervals from each other, and in interrupted 
longitudinal series (fig. 7). They are triangular, somewhat 
constricted at the middle, and have blunted  aculeated 
extremities; they measure 0.3037” long, 0.018”” broad at 
the extremities, but 0.0167” broad at the middle (fig. 7). 
The polyps are cylindrical. Their body is about 
2" Jong, and is pale rosy-red in colour; whilst, the tentacles 
are 3 times the length of the body, and are a little paler 
in colour than it; inthe middle of the aboral surface, there 
is a series of reddish spicules, in form and size, like those 
of the previously described species. 
The sarcosoma is thin, semitranslucent, and, every- 
where, rich in spiculæ, excepting, only, the point where 
the wall of the cell is concreted. 
The axis is round, and terminates above, in a small 
cone, devoid of sarcosoma. It terminates below, fine as a 
hair, in a hook. Whether the axis extends right down to 
the bottom of the bulbous part, or, whether it curves off 
further up, cannot decided, because, the sarcosoma 
of the whole stem was torn off by the dredge.

Colour. 
The rachis is brick-red, and strongly resplendent owing to 
it’s wealth of spiculæ. The cells are a little paler in colour, than 
the rachis; and the polyps, with their tentacles, are still paler.
