 magni, in verrucas (columnas) fere hemispbæricas octora-

Hyppig ved Finmarken, f. Ex. ved Vadsø, Øxfjord 

 etc. paa 60 — 100 Favnes Dyb og, som jeg af Exemplarer 

 i Kjøbenhavns Universitetssamling har seet, ogsaa ved 

 Grønland. Den har nogen Lighed med den middelhavske 

 Alcyonium palmatum, Pallas; men adskiller sig fra denne, 

 som kun har faa og fingerformede, i samme Plan stillede 

 Grene, ved sine rundtom Stammen (dog med Tilbøilighed 

 til at ordne sig i samme Plan) staaende talrige (hos 3" 

 høie Exemplarer indtil 20 — 24 i Tallet) tætsiddende, i En- 

 den but tilrundede Grene, hvilke atter ere besatte med 

 flere eller færre (1 — 10) korte Smaagrene.

ALCYONIUM FRUTICOSUM, Saes 

 The following description of the above species, which was 

 formerly sketched by the late Professor Sars 2 ), stands in connexion 

 with fig. 8, 9, 10, 11, tab. 3. 



Basis (pes sterilis) 1 — 2" lata, sæpius lobata, mem- 

 branacea, expansa, aliena corpora obducens. Stipes erectus, 

 cylindricus, tripollicaris, 7 3 " crassus, undique ramis densis 

 obsitus ; rami pollicares aut minores, apice obtuse rotun- 

 dato, ramulis similibus brevioribus præditi. Polypi magni, 

 in verrucas (columnas) fere hemispbæricas octoradiatas 

 retractiles. Color pallide miniaceus seu aurantiacus, basi 

 rubicundo-grisea aut plumbea, polypis roseo-albis hyalinis. 



Frequent in Finmark, for instance at Vadsø, Oxfjord 

 &c at the depth of 60—100 fathoms, and, as I have 

 seen from specimens in the collection of the university 

 in Copenhagen, also near Greenland. It has some resem- 

 blance to the Mediterranean Alcyonium palmatum Pallas, 

 but differs from the latter, which has only a few finger- 

 like branches placed in the same plane, by its numerous 

 branches standing round abont the stem (yet with a ten- 

 dency to arrange themselves in the same plane). In spe- 

 cimens 3" high, these branches were up to 20—24 in 

 number, situated close together, and obtusely rounded at 

 the extremity. The branches are moreover furnished 

 with a greater or less number (1 — 10) of short small 

 off-shoots.
