The present paper contains notes (in some cases due to the 

 valued help of friends) on Beroe, Arachnactis, Podon, the Ostracoda, 

 the Copepoda, the Amphipoda, and the Schizopoda, captured by 

 H.M.S. Research' in 1896 and 1897 in the Faeroe Channel. 



CTENOPHORA. 

 BEROE CUCUMIS Fabricras. 



This species, characteristic of cold Arctic currents 2 , was taken in 

 the following hauls : 



16 a ii., 300 to 170 fathoms, seven specimens. 



13 e, 400 to ? fathoms, one fragment. 



20<:Z, 500 to 400 fathoms, one specimen. 



Most. specimens showed the characteristic brick- red or rose tint, 

 and though much battered and in some cases inverted, were 

 referable with a fair amount of certainty to this species. 



ANTHOZOA. 

 ARACHNACTIS ALBTDA M. Sars. 



Some information as to the developmental succession of the 

 mesenteries in this form was given in No. III. of this series. 

 Since its publication, I am glad to say that it has been substanti- 

 ally corroborated by Prof, van Beneden 3 . 



He agrees with my suggestion to separate the Channel and 

 North Sea Arachnactis from albida of the Faeroe Channel, and 

 describes it under the name of lloydii, under the idea, which is 

 probable, but at present unproved, that it will be shown eventu- 

 ally to be the larva of Cereanthus lloydii. Till this has been 

 proved, I venture to think it better to retain my provisional name 

 of bournei for this form. 



The occurrences of A. albida are shown in the table (p. 118) : 

 it occurred in over 61 per cent, of epiplankton hauls, never in a 

 mesoplankton haul, and may fairly be taken to be a purely 

 epiplankton form. It was present in considerable quantity, as 

 many as 50 specimens having been taken in one haul.

 p. 991; No. II., 1897, p. 523 ; No. III., 1897, p. 803 ; No. IV., 1898, p. 540; No. V., 

 1898, p. 550; No. VI., 1898, p. 567 ; No. VII., 1898, p. 1016. I regret that various 

 circumstances, mostly beyond my control, have caused so great a lapse of time 

 between this paper and No. VII.
