We may now summarise the distribution of these 68 species which extend into the 

 tropical and northern extra-tropical regions, as follows : — 



Bathymetrical Distribution. — It appears that of these 68 species, 31 species are 

 known to occur only in depths greater than 1000 fathoms, while 37 species are 

 recorded from both above and below the 1000 fathoms line (of which 12 species 

 extend into shallow water under 150 fathoms ; to these 12 species we must add 8 of 

 the species confined to the Southern Hemisphere which have been recorded from 

 shallow water under 150 fathoms).
