and proportionally much ramified. I think it would not be difficult in a large material of Moore's 

 G. sent a to find forms approaching H. nodosa and vice versa. I also think that I have found such 

 an intermediate form, the specimen taken by ■•Tjalfe" in 62°58' N. L. 50°52' W. L. in Davis Strait. 

 Whether that specimen should be called //. senta or H. nodosa is after all rather immaterial. 



As it interested me in this connection to learn the real facts as to the relating forms from the 

 „Norske Nordhavs Expedition" described by G. Armauer Hansen, I adressed myself to Professor 

 Brinkmann, Director of the Zool. Museum in Bergen, who kindly lent me the types for examination. 

 The species which in this connection interested me particularly were the following: Polynoe assimilis, 

 P. foraminifera, P. arctica, P. spinulosa, P. islandica. The examination gave the result that P. assimilis 

 was identic with Nychia globifera, Sars; the other four species were rather common variants of H. nodosa. 



Finally I shall only remark that it is possible that the species here characterized must later 

 be divided into more or less species or sub-species viz. varieties, but I think it will be necessary to 

 examine a rather great material to settle the question whether we have here to do with only one 

 highly varying species or with more distinct species.

Some fragments from the named locality seem to agree with the species described by Mc. Intosh 

 under the name of L. floccosa. 



According to my opinion, Malmgren's Lagisca propi)iqua cannot be referred to this species as 

 Mc. Intosh suggests. A comparison of my figs. PI. II, fig. 14 and PI. Ill, fig. 3, plainly shows the 

 difference between the scales of the two species. It is here seen that, while all the great bodies in 

 the scale of H. propinqua are almost globular, they differ in form in the same scale oi H. floccosa; one 

 of them is almost globular, another is bluntly conical, a third is acutely conical. The microscopical 

 bodies in the scales also differ in the two forms. In IF. propinqua they show a tendency to divide, which 

 is not the case in H. floccosa, in which they are conical and acute, the largest among them are slightly 

 curved, resembling small spines. (See further under Hannothoe propinqua p. 00).
