from it. Hansen and Meinert regard iV. mixtum as a form of this species, and

 632 fathoms (' Porcupine,^ 1869) ; Greenland {A. Hancock) ; Eastport,

Hoek records the species as having been taken by the ' Knight Errant ' in 

 the cold area of the Faroe Channel ; and by the ' Triton ' in both the Faroe 

 Channel and the warm area south of the Wyville Thomson Ridge. This has 

 generally been regarded as an Arctic form, and Sars has not found it south 

 of the Arctic Circle on the Norwegian coast ; its not unfrequent occurrence 

 therefore on our eastern coast from the Firth of Forth to the coast of 

 Durham is of considerable interest. Orkney and Moray Firth {D' Arcy
