tindes ai' dette Dyr, leverer jeg saadanne paa T. I, Fig.

 upice furcata seu biaispide; dette er ikke Tiltældet hos 

 det paa Stat. 275 indfangede Exemplar; hos dette have 

 Børsterne^ i'n enkel, hist og her lidt krunnnet Spids (T. I, 

 Fig. 5). 



Jeg meddeler hernæst den ovenfor nævnte Fortegnelse 

 over de i den kolde Area tundne Annelider, ordnede efter 

 de Familier de tilhore.

The specimen obtained was linusually large. Sårs 

 states the length of his Norwegian specimens to have been 

 8""" and the breadth 4"""; but this s])ecimen. though much 

 shrunk from the action of the alcohol in which it was 

 preserved, measured 15""" in length and 8"'"' in breadth. 

 The animal not having previously been figured, -represen- 

 tations are given here, in PI. I, figs. 1 — 5. According to 

 Sars, the setæ are furnished apke furcata seu hicuspide; 

 this, however, is not the case with the specimen brought 

 up at Station 275, its setæ having a simple, straight, and 

 here and there very slightly arcuate point (PI. I, fig. 5). 



I will now annex a List of the Annelids collected 

 in the Cold Area, arranged under the famibes to which 

 they belong.
