Amphipoda Synopidea. 31 



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

 found for the first time at ))Havbroen)), a hank, 150 — 300 fathoms deep, 

 some twenty miles off 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 

 ))Hardangerf jord)), at a depth of 250 fathoms, parasites on, or in com- 

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

 young specimens at ))Tjotto)), on the west coast of Norway, some twenty 

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

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