164 THE VOYAGE OF H.M.S. CHALLENGER. 



323, off Buenos Ayres. Arcturus abyssicola was dredged in the western limits of the 

 Pacific, off North Australia, and in the middle of that ocean near to the Low 

 Archipelago. I might add to this list Ischnosoma bacillus, dredged between Australia 

 and Kerguelen, which is represented by a very closely allied if not identical species, 

 Ischnosoma bacilloides, at Station 302, off the east coast of South America, and 

 also Eurycope atlantica, dredged in the North Atlantic, which has at least a close 

 ally in a species obtained near the Crozets. It is hardly worth while to refer to 

 species which were dredged so near to each other as Stations 146 and 147, or Stations 

 168 and 169.
