depth from which this species was brought up is from 515 to 540 fathoms. The stations 
where it was found are the following :— 
Station No. 5 (cruise of the “ Knight Errant”). Lat. 59° 26’ N., long. 7° 19’ W. 
August 11, 1880. 515 fathoms. Warm area. Two specimens. 
Station No. 7 (cruise of the “Knight Errant”). Lat. 59° 36’ N., long. 7° 18’ W. 
August 12,1880. 530 fathoms. Warm area. Two specimens. 
Station No. 8 (cruise of the “ Knight Errant”). Lat. 60° 3’ N., long. 5° 51’ W. 
August 17, 1880, 540 fathoms. Cold area. Ten specimens. 
In this animal, therefore, we have an example of one inhabiting the cold and 
warm areas on both sides of the ridge rising in the Faroe Channel to within 300 fathoms 
of the surface." This agrees very well with the facts of the geographical distribution of 
our species ; it is a common inhabitant of the depths of the Arctic Sea, but it is also by 
no means rare in the deeper water of southern latitudes, especially in the neighbourhood 
of the American coast.

A single specimen of this species was dredged at 
Station 8 (cruise of the “ Knight Errant”). Lat. 60° 3’ N., long. 5° 51° W, August 
17, 1880. 540 fathoms. Cold area. 
For the geographical distribution of this species I refer to the list of species at p. 20.

Of this interesting inhabitant of the cold area of the Faroe Channel about thirty 
specimens were dredged during the cruise of the ‘‘ Knight Errant.” As hitherto neither a 
full description nor any figure of this species has been published, I wish to give both here. 
Only a short diagnosis of this species has been published by Professor G. O. Sars. 
From this, and from the pencil drawing he had the kindness to send me, the species ‘is 
easily recognised. However, in some respects, I observed slight differences from the 
diagnosis of Professor G. O. Sars. Probably these will be found to arise from the 
fact that the species had been submitted only to a preliminary investigation by the 
celebrated Norwegian zoologist. 
Nymphon macronyz, G. O. Sars, is a somewhat robust Nymphon, having the second 
joint of the palpi longer than the third, the first tarsal joint not quite half the length of 
‘the second tarsal joint, and having a very long claw at the end of every leg and
