lat. 68° N., long. 2° W.), or the parallel of the Lofoten 

 Islands, the great abyss of this part of the Arctic Ocean is 

 reached in 2000 fathoms. Now the fauna of the " warm 

 area " to the south of this ridge exhibits a more southern 

 character, different from that of the " cold area " of the Faroe 

 Channel, which latter is more arctic, and the British line of 

 demarcation driven from long. 5° W. direct N.E. past Shet- 

 land is chosen for the purpose of excluding the " cold area," 

 which belongs more properly to the Arctic Ocean generally 

 and to Faroe in particular *. 



In 1887 a committee was appointed by the British Associa- 

 tion to consider the question of the British Area, and their 

 Report (Brit. Assoc Rep. 1888, p. 95) the following year is 

 here ffiven : — 



u Report of the Committee, consisting of Canon A. M. Norman, 

 Mr. H. B. Brady, Mr. W. Carruthers, Professor Herd- 

 man, Professor W. C. M'Intosh, Mr. J. Murray, Professor 

 A. Newton, Mr. P. L. Sclater, and Professor A. C. 

 Haddon [Secretary] , appointed for the ]nirpose of con- 

 sidering the question of accurately defining the term 

 i British ' as applied to the Marine Fauna and Flora of 

 our Islands. 



11 A circular giving in detail alternate boundaries for a 

 British marine area, and maps and sections illustrating the 

 same, was distributed to members of the ' British Marine 

 Area Committee,' as well as to a large and representative 

 number of naturalists interested in marine zoology. As was 

 to be expected, the replies showed that great diversity of 

 opinion exists not only as to the desirability of limiting a 

 British marine area, but also as to how far such an area 

 should extend. 



" A tabulation of replies was subsequently forwarded to 

 the members of the Committee, and the following statements 

 appear to express the views of the majority : —
