Kölliker udtrykker sig med Hensyn til den af ham 

 opførte Varietet lancifolia saaledes: „Diese Varietät hat 

 bis jetzt wohl allgemein als ächte P. phosphorea gegolten." 

 Heri ere vi fuldkommen enige, og ikke ganske skjønne yi, 

 hvorfor denne Varietet er opstillet, da derved Grundtypen 

 aabenbart er forsvunden. Det er imidlertid uundgaaelig 

 nødvendigt at opretholde denne, for derfra at kunne ud- 

 lede Varieteter, forsaavidt saadanne existere. Vi have 

 derfor i Overensstemmelse med Kölliker opført hans lan- 

 cifolia som Linné's ægte phosphorea og ladet den være 

 Grundformen; og dette have vi gjort med desto større 

 Sikkerhed, som lancifolia er den almindelige i Norden. 

 Vi have aldrig seet den af Kölliker opførte Varietet an- 

 gustifolia; men en Mængde af lancifolia og dennes Sub- 

 varietet variegata.

 Kölliker angiver, at den største Længde af de Exempl., 

 han havde til Undersøgelse, uclgjorde]116 Mm. Det største 

 af vores Exempl. havde en Længde af 195 Mm.; forøv- 

 rigt svare alle Characterer til den af ham givne Be- 

 skrivelse. 



Paa flere Exemplarer af Pennatula phosphorea, Lin. 

 og varietas variegata gik Axen lige op til Enden af Hachis, 

 og paa 4—5 Mm. nær, ned i Stilkens Spidse. Paa 1 

 Exemplar gik Axen kun ganske lidet op over Midten af 

 Rachis, men gik derimod lige ned i Enden af Stilken. 



Findested: I Fjordene omkring Bergen, men ikke 

 almindelig, paa en Dybde fra 40 — 50 Favne.

') I November 1859 gjorde^eg i Videnskabsselskabet i Christiania 

 opmærksom paa, at Koren havde fra Varangerfj orden faaet en Søfjær, 

 som han allerede i 1855 havde opstillet i Bergens Museum under Nav- 

 net „Virg. affinis." Nogle Aar senere (1857) fandt Sars og jeg den 

 ved Vadsø. Paa en Etikette havde Sars opført Navnet glacialis 

 for den; men beskrev den aldrig, da han vidste, ikke alene at den 

 tilhørte et Arbeide, Koren og jeg var beskjæftiget med, men at der 

 endog var optaget en detailleret Tegning af den, just den samme, 

 som nu leveres i 3die Hefte af Fauna littor. Norvegiæ. Dette er 

 Grunden til, at Korens oprindelige Navn nu gjenoptages.

PENNATULA PHOSPHOREA, Lin. 



Synon. P. phosph. variet. lancifolia, Kölliker, 1. c. pag. 131, fig, 7q 

 Kölliker expresses himself with respect to this variety 

 lancifolia established by him as follows: "Diese Varietät 

 hat bis jetzt wohl allgemein als ächte P, phosphorea 

 gegolten". With this we quite agree, and do not quite 

 understand why the variety is established, as the typical 

 form would thus disappear. It is however indispensibly 

 necessary to maintain a typical form, in order thence to 

 derive varieties, forasmuch as any such exist. We have 

 therefore, agreeing with Kölliker, placed his lancifolia as 

 Linneus 5 genuine phosphorea, and retained it as the funda- 

 mental form; and we have done this with so much the 

 greater assurance as the lancifolia is the common form 

 in the North. We have never seen the variety angusti- 

 folia established by Kölliker, but a number of lancifolia 

 and of the subvariety variegata. 



PENNATULA PHOSPHOREA VARIET. VARIEGATA. 



Synon. P. phosph. v. lancifolia subvarietas variegata, Kölliker. 

 Kölliker states that the greatest length of the speci- 

 mens he had for examination was 116 Mm. The largest 

 of our specimens had a length of 195 Mm. In other 

 respects the characters answer to the description given 

 by him. 



In many specimens of Pennatula phosphorea, Lin. and 

 varietas variegata, the axis went right up to the end of 

 the rachis, and within 4—5 Mm. of the point of the 

 stalk. In one specimen" the axis went only a little way 

 above the middle of the rachis, but to the very end of 

 the stalk. 



It is found in the fjords round about Bergen but not 

 abundantly, at the depth of 40—50 fathoms.

1 ) In November 1859 I called the attention of the scientific 

 society in Christiania to the fact that Koren had got from the Varan- 

 gerfjord a sea-pen which he had already in 1855 placed in the Mu- 

 seum at Bergen under the name "Virg. affinis". Some years after- 

 wards (1857) Sars and I found it at Vadsö. Sars had written for 

 it the name glacialis on a ticket, but never described it; as he 

 knew, not only that it belonged to a work with which Koren and 

 I were occupied, but also that it had been delineated in detail in 

 the said work exactly as now published in Tom. 3 of Fauna littor. 

 Norveg. This is why Koren's original name is now again adopted.

2 ) Kölliker has adopted this name from a ticket in the Copen- 

 hagen museum.
