Vi have fundet den i Korsfjorden ved Bergen paa en 

 Dybde af 300 Favne, blandt Koraller. Koren har seet 

 hos Professor G. O. Sars Exemplarer af den samme Art, 

 som han havde fundet paa lignende Dyb i Coralregionen, 

 hvor den forresten forekommer i stor Mængde. 



Zoanthus norvegicus nærmer sig mest til Z. anguicoma, 

 Norm., og Z. Couchii, Johnston, men adskiller sig dog 

 væsentlig fra Begge. 



Zoanthus anguicoma har et Cænosark, der danner 

 småle Baand, hvorfra Polyperne reise sig; disse ere kun 

 lidet bredere foroven (næsten cylindriske), have omtr. 34 

 Tentakler, der ere meget længere end Skiven. Farven 

 er blegrød-hvid. 



Zoanthus Couchii forekommer ligeledes i baandformige 

 Udbredninger. Polyperne ere cylindriske. Tentaklerne 28, 

 temmelig korte. Kroppens Farve er bleg-brun af det 

 incrusterede Sand, forøvrigt farveløs og transparent; Ski- 

 ven gjennemskinnende graalig-rød med fine hvide Pletter; 

 Tentaklerne næsten farveløse med hvide Spidser, og Mun- 

 den omgiven af en hvid opak Ring. 



Vor Art forekommer i større og mindre klump edan- 

 nende Grupper med et fast incrusteret Cænosark, der 

 udbreder sig over store Flader, og hvorfra de køllefor- 

 mige Polyper udspringe. Tentaklerne sidde i to Rækker, 

 18 i hver, og de indre ere længere end Skiven i udstrakt 

 Tilstand. 



ARTSCHAKACTEKEN. 

 Cænosarket fast, læderagtigt, udbredt i store Flader 

 og stærkt incrusteret med brungul Sand. Polyperne køl- 

 leformige, tæt siddende i store Grupper. Tentaklerne i 2 

 Rækker, 18 i hver; de indre længere end Skiven. Over- 

 huden graagul, incrusteret. Skiven bleg-rosenrød med 

 hvide Striber. Munden omgiven af en mørkere rosenfar- 

 vet Ring. Tentaklerne rosenrøde.

Anmærkning. Paa Tabula 4 findes afbildet under Fig. 8 Ceri- 

 anthus Lloydii, liggende i det aabnede hudagtige Rør, samt under 

 Fig. 9 Mundpartiet med Tentaklerne af samme Dyr. Dengang det 

 Dyr blev tegnet, antog jeg (Danielssen) det for en ny Art, som 

 blev benævnt Cerianthus borealis, men vi bleve senere opmærk- 

 somme paa, at det var Gosse's Cerianthus Lloydii. Den fandtes 

 først af os i Moldefjorden, og var da ny for Skandinaviens Fauna. 

 Senere er den af os funden i Bergensfjorden. Den forekommer paa 

 dyndet Bund paa en Dybde fra 20 til 50 Favne. 



We have found it in the Korsfjord at Bergen, at the^ 

 depth of 300 fathoms among corals. Koren has seen in 

 the possession of Professor Gr. O. Sars, specimens of the 

 same species which he had found at the same depth in the 

 coral region, where moreover it occurs in great numbers. 



Zoanthus norvegicus resembles most Z. anguicoma, 

 Norm, and Z. Couchii, Johnst. but differs nevertheless 

 essentially from both of them. 



Zoanthus anguicoma has a Coenosark which forms 

 small ribbons, whence the polyps rise: the latter are only 

 a little broader above (nearly cylindrical); they have 

 about 34 : tentacles, which are much longer than the disc. 

 The color is pale reddish white. 



Zoanthus Couchii occurs also in ribbon-like extensions. 

 The polyps are ^cylindrical. The tentacles 28, rather short 

 The color of the body is pale-brown from the incrusted. 

 sand, otherwise the body is colorless and transparent. 

 The disc is translucent, greyish red with fine white spots. 

 The tentacles nearly colorless with white points, and the 

 mouth surrounded with a white opaque ring. 



Our species occurs in larger and smaller clod-like 

 groups, with a firmly incrusted Coenosark extending itself 

 over large surfaces, and whence the club-shaped polyps 

 proceed. The tentacles are situated in two rows, 18 in 

 each, and the interior ones are longer than the disc, when 

 they are extended. 



CHAKACTERISTICS OF SPECIES. 

 The Coenoesark solid, leathery, spread over large sur- 

 faces and strongly incrusted with brownish-yellow sand. 

 The polyps club-shaped, situated closely in large groups. 

 The tentacles in 2 rows, 18 in each; the interior ones 

 longer than the disc. The epidermis greyish yellov, in- 

 crusted. The disc, pale rose-colored with white stripes. 

 The mouth surrounded with a darker rose-colored ring,. 

 The tentacles rose-colored.

Note. In Tab. 4, there is delineated fig. 8 the Cerianthus 

 Lloydii, lying in the opened skin-like tube; also fig. 9 the oral 

 part, with the tentacles, of the same animal. When tbis animal 

 was drawn, I (Danielssen) considered it to be a new species which 

 was called Cerianthus borealis; but we subsequently perceived that 

 it was Gosse's Cerianthus Lloydii. It was found first by us in the 

 Moldefjord and was at that time new as regards the Fauna of 

 Scandinavia. We found it afterwards in the Bergenfjord. It occur* 

 on miry bottom at a depth of 20 to 50 fathoms.
