Amphipoda Synopidea. 31 



Hab. The Arctic Sea, the_ North Atlantic. The animal was 

 found tor the first time at »Havbroen)), a bank, 150 — 300 fathoms deep, 

 some twenty miles ofl' the west coast of Norway, by Professor Rascii, of 

 the Christiania University; later at »Throndhiemsfjord)^, more to the 

 north on the same coast, by Conservator Storm. This specimen was 

 parasite on a shark. In the year 1880 I found some specimens in 

 )iHardangerfjord», at a depth of 250 fathoms, parasites on, or in com- 

 [Kiny with, an Asterias. Some years before I had got about twenty 

 young specimens at »Tjöttö», on the west coast of Norway, some twentj^ 

 miles south of the polar circle. A very young one was also taken by 

 A. BoECK in »Christianiafjord)^, the south coast of Norway, at a depth 

 of (iO fathoms. I am also informed that some specimens of the animal 

 were captured at the west coast of Novaja-Zemlja by Captain Collin.
