Only females are known. A single specimen has been found on the upper surface of the 

 pace of Sfrgestfs arcticus Kr.; its head was directed backwards and situated a little before the post- 

 erior end of the carapace. It is highly probable that the parasite always infests that Decapod. The 

 specimens hitherto captured were taken in young-fish trawl or - - the Monaco specimen in a 

 vertical net 



Occurrence. Not taken by the "Ingolf", but by the "Thor" and the "Tjalfe".
