ReniayJis. — There cannot now, I think, be any doubt that this form 

 is in reality identical with the Lt/sianassa magellanica of Milne Edwards, al- 

 thongli the occurrence of one and the same species liotli in the Arctic and Ant- 

 arctic seas would seem to l)e 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- 

 tication. 



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 opportiinity 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 unaltex'ed. From one 

 of these sjiecimens 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 

 fisli»; 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.

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