Cribrilina monoceros , Busk. Japan. 
Synaphobranchus bathybius , Gunther. Japan. 
These coincidences are, to my mind, important, hut they are far 
from proving the “bipolar hypothesis.” Information is slowly 
growing in regard to the affinities of the Japanese fauna with that 
of the western American coast, and this faunistic relation between 
the Japanese, the western American, and the far southern forms 
is, in my opinion, an important and indisputable one. 
After considering and deducting the forms enumerated above, 
the list with which we started shrinks into little space. There 
remains, in the first place, the little Copepod Harpacticus fulvus , 
found in the brackish pools of Kerguelen Island, which rather be- 
longs to the question of the distribution of fresh-water animals, a 
problem totally distinct from that of the marine. We next have a 
single Annelid, Terebellides Stromii , M. Sars. The few remaining 
forms belong either to the pelagic or to the abyssal fauna of the 
ocean. In the former group we have two instances, namely, 
Ianthina rotundata, Leach. 
Calanus finmarchicus, Gunner. 
The latter of these is the commonest and most widely distributed 
of all the Copepods. It does not seem to be recorded from further 
south than the Cape, its place being taken at Kerguelen by C. pro- 
pinquus, Brady, which occurs there in the same abundance as 
C. finmarchicus in Arctic seas. The former is widespread over 
the Atlantic ; and neither of them is recorded, to my knowledge, 
from further south than 35° S. lat. 
We are left with the following list of deep-water or abyssal 
species 
Elpidia glaeialis , Theel. 
Euphronides depressa, Theel. 
Ophioglypha bullata , Wy. Th. 
Ophiocten hastatum, Lym. 
Ophiernus vallincola , Lym. 
Pont aster forcipatus, Slade n. 
Dy taster exilis, Sladen. 
Kinetoskias cyathus 3 K. and D.
