that they really lived south of the cold depths of the Faroe Channel. He 

 wrote (29. p. 1) : — ''^ Nymphon macronyx, G. 0. Sars is represented by hundreds 

 of specimens from the cold area and by one specimen only from the warm 

 area; and this is also the case with Nymphon robustum, Bell. Of both 

 species the number of specimens collected at stations in the cold area was so 

 large, that the occurrence of one specimen at a station in the warm area seems 

 rather unimportant — it must be considered as a specimen which has got 

 astray ; but whether this happened before or after its being dredged I cannot 

 say with certainty. As in both cases the station in the warm area from which 

 the single specimen was obtained follows one in the cold area from which several 

 hundred specimens of the one and upwards of fifty of the other species were 

 collected, it is even probable that the same fishing apparatus (trawl) beino- 

 used — one specimen was overlooked, either remaining between the meshes of 

 the trawl, or clinging to the rope. The nature of the animals with their long-^ 

 and numerous legs, each furnished with a claw, favours this suggestion.'^ 



Hoek's caution is greatly to be commended ; and I should not have had 

 much hesitation in applying it to even the four examples from the warm area 

 in my collection, if it had not been that they were distinctly different from 

 those in the cold area in their paler colour and much greater transparency. 



A male from the cold area is curiously abnormal, the ocular tubercle is 

 altogether absent, not a vestige of it can be seen.

 which were in the Faroe Channel ; and as it was not taken by the 'Porcupine" 

 anywhere south of the Wyville-Thomson Eidge, additional weight is given to 

 the suggestion of Hoek (see under Chcetonymphon macronyx) that the single 

 specimen said to have been procured by the ' Triton ' in the warm area was by 

 error assigned to that locality. I may say that Stat. 65 is exactly on the
