Copepoda. 35> 
As a general conclusion of the foregoing demonstration of 
facts we may state, that there are in the North Atlantic several 
arctic copepods, the occurrence of which is referable to trans- 
port by arctic currents. On the other hand we may expect to- 
find Atlantic species in the Norwegian Sea. Such Atlantic pioneers 
towards the North can also be enumerated, viz. Eucalanus 
elongatus, Rhincalanus nasutus, Aetideus armatus, Aetideopsis 
rostrata, Pleuromamma robusta, Haloptilus longicornis, Anoma- 
locera patersoni, Pontella wollastoni, etc. 
Eucalanus elongatus DANA is recorded from Skagerak by 
AURIVILLIUS, and the species will probably also be found in the 
Norwegian sea. 
-— Rhincalanus nasutus GIESBRECHT is noted from the North sea. 
and Norwegian sea by G. 0. SARS. 
Aetideus armatus BOECK has been captured in the Norwegian 
sea and in several of the southern and western Norwegian fjords. 
up to the Finmark coast. 
Aetideopsis rostrata G.0. SARS appears to ae a rare visitor 
in the Norwegian sea. 
Pleuromamma robusta DAHL has been taken in single speci-. 
mens up to the Lofoten islands. 
Haloptilus longicornis craus. A single female specimen of 
this species was recorded by a. o. sars) from a station between 
Finmark and Bear island. The distribution of H. longicornis is 
principally southern, and we are inclined to think, that the oc- 
currence at such a high northern latitude is referable to trans- 
port by the warm current in the Norwegian sea. As we have 
said before, H. acutifrons may be regarded as an arctic species. 
Anomalocera patersoni TEMPLEION. Of this species G. 0. SARs) 
writes: »The true habitat of this form is undoubtedly the open 
ocean, and it is only after heavy gales, and by the accompanying 
strong sea-currents that it is occasionally brought close to the 
shores and into the fjords. Off the west coast of Norway, where 
it is known to the fishermen as »Blaa-aate« (blue bait), its pre- 
sence in the fjords is a very good sign of the approach of the 
summer-herring«.
