1 . Briareum grandiflorum ; 2-3-pollicare, niiniatum, basi effusa, 

 tenui ; ramis cylindricis, gracilibus, patulis, flexuosis et tortuosis, 

 (lichotomis ; cellulis polyporum maximis (diametrum rami duplicem 

 longitudine sequantibus), cylindricis, sparsis, ad apicem ramorum 

 densioribus seu coacervatis ; polypis non retractilibvis. 



Taken at Cxfjord in Finmark, at a depth of 200 fathoms, attached 

 to living specimens of Oculina prolifera, to dead branches of Primnoa 

 lepadifera, and to the tubes of Tuhularia indivisa ; often covering 

 these objects with a coating of isolated polypiferous cells and ascend- 

 ing branches. 



2. Rhizoxenia Jiliformis ', 2-3-pollicaris, cinereo-albida ; basi com- 

 iriuni repente filiformi, diametrum cellularum polypiferarum conico- 

 convexarum bis crassiorum longitudine bis-ter superante ; polypis 

 albis, retractilibus. 



Taken once at Manger, at the depth of 30-40 fathoms, attached 

 to a large stone. Sarcodictyon catenata, Forbes, also belongs to 

 this genus. 



3. Virgularia Jlnmarchica ; 40-pollicaris, sanguinea ; stipit^ 

 sterili crassiore, fasiformi, 6-7-pollicari ; pinnulis utrinque 100-112, 

 crassitudinem stipitis sequantibus vel paululum superantibus, semi- 

 lunaribus, sessilibus, latera et faciem anteriorem stipitis oblique cir- 

 cumdantibus (dorso nudo relicto), seriem cellularum 8-10, spiculis 

 densis fasciculatis farctarum, gerentibus. 



Taken only at Oxfjord in Finmark, in the deepest part of the bay, 

 at a depth of 240 fathoms, with the barren part of its stem buried 

 in the mud. It is frequently brought up by the hooks of deep-sea 

 lines. 



Of the family Pennatulidce, of which only three species are re- 

 corded as British by Johnston, no less than seven occur on the 

 Norwegian coast. These are — 



Pennatula phosphorea, Linn. (P. ruhrUy Ehrb., not Linn.) 



Pennatula borealis, Sars. 



Pennatula stelHfera, Miiller (Kophohelemnon Mulleri, Asbjornsen, 

 Fauna Litt. Norv. ii. p. 81). 



Virgularia mirabilis, Miiller. 



Virgularia Christii, Koren and Danielssen. 



Virgularia Jinmarchica, Sars. 



Pavonaria quadrangularis, Blainville. 



Genus Ulocyathus, Sars. 



Polypariunicalcareum, turbinatum, simplex, liberum, cum vestigiis 

 adhsesionis (in setate juniore) in basi brevissima, cuneiformi, adunca, 

 acuminata. Costse parum eminentes, interdum obscurse. Calyx 

 profundissimus, margine sinuato et crispo. Columella nulla, patuli 

 nulli. Lamellse radiantes (septa) tenuissimse, altse, super marginem 

 calycis valde prominentes, tota longitudine discretae. Animal sim-
