The annelids are small, tlic largest mcasiiiMiig about four 

 inches long and having 80 segments. Tlie Alonograpli 

 states "body 4—1) ins. long and segments C5 to 110," while 

 Ileiuen, the (Jerman investigator, gives 60 to 80 as the 

 general number. As far as can be ascertained, all the hauls 

 were made beyond 58° N., and the greatest depth reeoriled 

 is 105 m. This species, however, abounds all round the 

 shores of Great ]?ritain and Ireland, and off St. Andrews it 

 is very plentiful in deep water. It has often been found 

 entering into symbiotic relationship with Par/urns bernhurdus 

 in Buccinum, both the large and the smaller varieties, and in 

 Fusus islandicns, according to Prof. M'lutosh, "part of the 

 animal is inserted within the shell and the anterior region 

 lies along the lip.^' Dr. Johnston found several of his 

 specimens in the same or allied shells with hermit-crabs. 

 The stomaciis of the cod and the haddock often yield largo 

 quantities of this annelid, which may be half digested, but 

 yet is easily recognized by the sti'ucture of its feet and 

 bristles. Olf Montrose Dr. Howden obtained very large 

 specimens in deep water, while J. G. Jeffreys obtained this 

 species 18 miles west of Skellig, Ireland, iu 80 fathoms 

 of water. Elwes found it at Torquay ; Andouiu and 

 Edwards around the shores of France ; Ehlers, Levinscn, 

 and others in the North Sea, and Verrill off the eastern 

 shores of xVmerlca. Neither Izuka nor the ' Challenger ' 

 records any of this species. Heiiien, in his North Sea 

 Investigations, records this annelid from many stations and 

 obtained it at a depth of 2'JO m. — " Exemplare dieser Spczics 

 {N. fucata) wurden in Tiefen bis zu 290 m. meist auf Satul- 

 oder Schlickgrund gefangen." His most northerly station 

 is lat. G0° 20', long. 2° 20' E.^
