legs beautifully vermilion -coloured. Length of an adult female specimen

Eemarks. - There cannot now, 1 think, he any doubt that this form 

 is in reality identical with the Lysianavsu- /(i</<'//<i>/fca of Milne Edwards, al- 

 though the occurrence of one and the same species both in the Arctic and Ant- 

 arctic seas would seem to be highly perplexing. The recent discovery of this 

 species, during the American Expedition of Albatross and the French Ex- 

 pedition of Hirondelle, in the great deeps of the Atlantic at intermediate 

 latitudes would seem still more to confirm the correctness of the above identi- 

 fication. 



Occurrence. - - All the specimens preserved in our Museum have been 

 extracted from the stomach of large sharks (Scymnus borealis), and as some 

 of these sharks notoriously were captured off the coast of Finmark, the species 

 may properly be referred to the Norwegian fauna, though it probably lives 

 outside the great fishing banks. Through the kindness of Mr. Schneider, cura- 

 tor of the Tromso Museum, I have had an opportunity of examining 2 speci- 

 mens procured by him, both of which were in an excellent state of preserv 

 ation, even still exhibiting the ocular pigment nearly unaltered. From one 

 of these specimens the habitus figure here given has been drawn, and from the 

 other the anatomical details. 



Distribution. - - Antarctic Ocean off Cape Horn, fromthe belly of a large 

 fish; Arctic Ocean: Greenland, Spitsbergen, from the stomach of sharks; At- 

 lantic, off the east coast of North America (Smith), and off the Azores (Chev- 

 reux), collected from very great deeps.

Body moderately slender, with the coxal plates of middle sixe. 1st 

 pair well developed and widening below. Last pair of epimeral plates of 

 metasome produced at the infero-lateral corners to a triangular upturned lobe.

 or less slender, accessory appendage well developed. Inferior antenna', as a 

 rule, somewhat longer than the superior, in male about twice as long as in
