Descriptions of some new Xorweyian Polypes. By M. Sars. 



1 . Briarcxnn grandiflonnn ; 2-3-pollicare, niiniatum, basi efFusa, 

 tenui ; ratiiis cylindiicis, gracilibu?, patulis, floxuosis et tortuosis, 

 dichotomis ; cellulis polyporum maximis (diametnim rami duplicem 

 longitudine aequaiitibus), cylindricis, sparsis, ad apicem ramoriim 

 densioribus seu coacervatis ; polypis non retractilibus. 



Taken at Oxf jord in Finmark, at a depth of 200 fatlioms, attached 

 to hviug 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. Bhizoxeiiia filiformis ; 2-3-pollicaris, cinereo-albida ; basi com- 

 niuni re{)ente 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. Sarcodicfijon catenata, Forbes, also belongs to 

 this genus. 



3. Virgularia finmarchicu ; 40-pollicaris, sanguinea ; stipite 

 sterili crassiore, fusiformi, 6-7-pollicari ; piunulis utrinque 100-112, 

 crassitudinem stipitis sequantibus vel paululum superantibus, semi- 

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

 cunidautibus (dorso nudo relictoj, 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 PennatuHdce, of which only three species are re- 

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

 Norwegian coast. These are — 



Penaatida phosphoren, Linn. (P. rubra, Ehrb., not Linn.) 



Pennatulu borealis, Sars. 



Pennatula stelUfera, Miiller (Kophobelemnon Miilleri, Ashiornsen, 

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



Virgularia mirabilis, Miiller. 



Virgularia Christii, Koren and Dauielssen. 



Virgularia fininarchica, Sars. 



Paronaria quadrangularis, Blainville. 



Genus Ulocyathvs, Sars. 



Polyparium calcareum, turbinatum, simplex, liberum, cum vestigiis 

 adhsesiouis (in setate juniore) in basi brevissima, Cuneiform!, adunca, 

 acuminata. Costse parum eminentes, interdum obscurse. Calyx 

 profundissimus, margine sinuato et crispo. Columella nulla, patuli 

 nuUi. Lamellae radiantes (septa) tenuissim.se, altae, super marginem 

 calycis valde prominentes, tota longitudine discretse. Animal sim- 

 plex, actiniforme, ore plicis numerosis, seviebus tentaculornm cnnico-
