1903.] PLANKTON OF THE FAEROE CHANNEL. 127 



Mr. Stebbing points out "that this species has been again 

 figured in great detail by Professor Sars *, and that Dr. Norman 2 

 has with almost equal fulness represented his Cyclocaris faroensis. 

 In Mr. Stebbing's opinion the differences between the two sets of 

 figures are purely casual, depending on individual or accidental 

 conditions of the specimens examined. Further, while accepting 

 provisionally the distinction between the boreal form and the 

 4 Challenger ' C. tahitensis, he agrees with the view thus expressed 

 by Dr. Norman, 'so remarkable is the resemblance, that the 

 differences seem scarcely varietal ; but I hesitate to unite a form 

 found in the Faroe Channel with one from so distant a locality as 

 Tahiti.' " 



Canon Norman does not appear to have known of M. Chevreux's 

 name (which apparently has priority) ; his specimens were captured 

 by the 'Triton' in the Faeroe Channel in 1882, at a depth of 

 640 fathoms. Professor Sars's specimens were apparently from 

 various depths along the course of the ' Fram,' the smallest 

 specimens at the least depths. 



This species (omitting tahitensis as specifically distinct) is 

 evidently a Polar and deep-water form. 



TRYPHANA MALMI Boeck. 



A single specimen, from haul 13 i, 100 fathoms to the surface, 

 was identified by Mr. Stebbing. The previous records of its 

 occurrence are: Hardangerfjord, 100 fathoms 3 ; from Nansen- 

 f jord to Hardangerfjord 4 ; Folgero, Sunde, Foldenf jord, 80 to 

 100 fathoms 5 . Sars 5 regards T. nordenskioldi Boeck and T. boecki 

 Stebbing as being the males of T. malmi. Of these the former 4 

 was described from the Sofia Expedition as off the Faeroe Islands 

 at 65 N., the latter 6 from 18 8' N., 30 5' W., at the surface. 



EUTHEMISTO sp. indet. 



A number of specimens too much broken for recognition 

 occurred in the haul 15 d at midnight. 



EUTHEMISTO BISPINOSA Boeck. 



Occurred in 15 c (530 to fathoms) and 15 d (surface, at mid- 

 night). The records of this species were exclusively Arctic, till 

 it was captured by the ' National ' expedition in the Sargasso Sea 

 between 218 fathoms and the surface. 5 



EUTHEMISTO COMPRESSA Goes. 



A single specimen at 12 e (450 to 320 fathoms). This also was 

 believed to be exclusively an Arctic form, but has now been
