Bathymetncal Distnhution. — 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 I'rom 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 tlie Southern Plemisphere which have 1hhmi recorded ffom 

 shallow water under 150 fathoms).
