We see, therefore, that the fauna in the continental (archibenthal) deep - sea area of the Northern At- lantic consists partly of species peculiar to it, and partly of others that regu- larly belong to the con- tinental deep-sea fauna of the Norwegian Sea. Two questions arise: How is the Atlantic archibenthal (and abyssal) fauna distri- buted outside the Nor- wegian Sea? Is there any real resemblance between this fauna v v and its counterpart k \ in the cold area of rWtV I te Norwegian Sea? \ There seem to Limits of the be some reasons for arenthal fixing the lower limit of the archi- benthal fauna at about 2000 metres, and the upper limit at about 800 or 1000 metres. The charts of the area south of the ridges published by the Danish ' Ingolf ' Expedition show that beyond 2000 metres the slope of the bottom becomes less steep downwards to the vast abyssal plain whose upper limit may be put some-
