Pandalus horealis, Kroyer, has only recently been added to 

 the British fauna. In July, 1907, about thirty examples were 

 caught in 57 fathoms, E.N.E. of the Coquet Lighthouse, oft 

 the Northumberland coast. The specimens were caught and 

 named by Mr. R. A. Todd, of the Marine Biological Associa- 

 tion, and their identification subsequently verified by Canon 

 Norman. P. horealis is described and figured in detail by 

 G. O. Sars, 1900. 



Within the last few years this species has been fished com- 

 mercially in certain Norwegian Fjords. The industry, which 

 owes its origin to the Norwegian Fishery Investigations, is now 

 in a very thriving condition, and numerous boats, using special 

 nets, are devoted exclusively to it.
