described in other Pennatulida" . This shows that he must have 

 prepared and subjected the axis in some specimens to a minute 

 examination, and therefore can hardly have altogether overlooked 

 its shape. For this reason, it is very probable that some specimens 

 have round axes, in which case K6llikeb's genus and species ought 

 to be retained. It would, however, be highly interesting to have 

 these specimens carefully re-examined. 



Funiculina quadrangularis or Leptoptilum gracile partim was 

 tåken by the „Challenger" Expedition N. E. of New Zealand (Sta- 

 tion 169, 37° 36' S, Lat., Long. 179° 24' E. of Greenwich). In 

 the same locality, the Expedition also found another northern Penna- 

 tulid, Kophobelemnon stelliferum. Might not several of the Penna- 

 tulida of the South Sea prove, on continuing the comparison, to be 

 identical with northern species? It can hardly be a mere accident 

 that two such characteristic forms as Funiculina and Kophobelemnon 

 stelliferum occur both in the northern and the southern seas. 



Kophobelemnon stelliferum, 0. F. Mull. 



In the ,,Aarbog" of the Bergen Museum for 1893 (No. 2, p. 

 11), I have endeavoured to show that the development in Kopho- 

 belemnon stelliferum is, on the whole, identical with that of Penna- 

 tula phosphorea. In Kophobelemnon, however, the terminal polyp in 

 all known stages is situated on the ventral side, somewhat below 

 the apex of the rachis, while the terminal zooid occupies the axial 

 place. In Pennatula, on the contrary, this place is occupied by 

 the terminal polyp, the terminal zooid being on the dorsal side. 

 Again, in Kophobelemnon, the first two rows of lateral zooids make 

 their appearance before the sexual polyps, for I have found them 

 as early as in a 22 mm. long specimen, while the first sexual 

 polyp could only be made out in a specimen 27 mm. in length. In 

 Pennatula, on the other hand, the sexual polyps appear before the 

 lateral rows of zooids. In the latter genus we also find the first 

 sexual polyp to the right of the terminal polyp, while in Kophobe- 

 lemnon it is situated to its left. 



Last summer, I had the opportunity of examining some young 

 specimens of Kophobelemnon stelliferum from Herlofjord, collected 

 by Dr. Appellof, as well as a young specimen (unfortunately 

 somewhat damaged), with only 4 polyps, from the TrondhjemlFjord.
