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

 pace of Sergestes arcficus 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 "Iugolf", but by the "Thor" and the "Tjalfe". 

 Davis Strait: Lat. 66°2i' N., Long. 57°04' W., depth 680 m., 800 in. wire out; 1 spec. "Tjalfe" 



(Stephensen). 

 — Lat. 64°22' N., Long. 56°oo' W., 400—800 m. wire out On Sergestes arcficus Kr.; 



1 spec. "Tjalfe" (Stephensen). 

 West of Iceland: Lat. 65°2o' N., Long. 27°i2'5' W., depth 440 m. 820 m. wire out; 1 spec. "Thor". 

 South of Iceland: Lat. 6i°3o' N., Long. i7°8' W., 1800 m. wire out; 1 spec. "Thor". 



Distribution. One specimen has been taken by Dr. Joh. Schmidt west of France in Lat. 

 48°09' N., Long. 8°3o' W., 300 in. wire out (Stephensen). The type specimen was secured by the Prince 

 of Monaco at a place south-west of the Azores: Lat. 3i°4o' N., Long. 36°55' W., 2500—0 m. (Koehler).
