littoral species which must be regarded as undoubtedly 

 "bipolar" is exceedingly limited, and that of abyssal and 

 pelagic forms is also very restricted. 



^A'ithout entering in this brief notice u])on a discussion of 

 the different views as to the cause of the " bipolarity," I wish 

 only, when recording a new " bipolar" crustacean, to express 

 iny agreement with Chun, when he says * : — " Wenn wir 

 audi bis jetzt nur ein sicher beglaubtiges Beispiel auzufiihren 

 vermogen, dass identlsche Avten beider polaren Gebiete durch 

 die ganze Breite des Oceans die tieferen und kiihleren 

 Kegionen bevolkern, so wird man immerhin uicht umhin 

 konnen, die Beweiskraft desselben anzuerkennen und niir 

 zuzugeben, dass heute noch ein Austausch zwischen den 

 polaren Faunengebieten stattfindet. Ich bin fest iiberzeugt; 

 dass eine Heissige Ausnutzung der Schliessnetze auf si)ateren 

 Expeditionen nicht nur neue Beispiele fiir einen Zusanimen- 

 hang der den kalten Gebieten eigentiimlichen pelagischen 

 Organisnien liefern, sondern auch noch nianchen Fund von 

 allgemeiner Tragweite darbieten wird." 



It is only to be expected that " die Deutsche Tiefsee- 

 Expedition," the leader of which was Professor Chun, will 

 yield important facts in this respect; and it is therefore that 

 everyone who is interested in these questions looks forward 

 with the utmost curiosity to tlie scientific results of that great 

 expedition.
