Geographical range. Heliometra glacialis has been recorded from Arctic seas and 

 southward to Georges Bank, off Cape Cod, Massachusetts, Iceland, the cold part of the 

 Faroe channel, northern Norway (west and east Finmark) and along the Siberian coast 

 and off-lying land masses to Wrangel Island, not far from the Bering Strait ; it has not 

 yet been recorded from north of Alaska and the Canadian arctic cast of Hudson Bay 

 and Jones Sound (long. 89 W.), though probably occurring in favorable situations. 



Bathymetrical range. In the following tabulation are given the entire bathymetri- 

 cal range and the ascertained ranges in several different areas'. These latter ranges are, 

 of course, dependent upon local conditions and limited by the amount of work done in 

 the various regions. They are interesting in showing the present state of our knowledge 

 rather than as definite statements of actual biological facts.
