The greater abundance of species and individuals procured on the Terrigenous deposits 
is thus clearly shown when compared with those captured on the Pelagic deposits, such 
as the red clays and organic oozes, excepting those of the Southern Ocean. The hauls 
with the trawl are, it will be noted, much more productive than those with the dredge. 
The trawlings in the Southern Ocean are remarkable for the large number of species Trawlixgs ix the 
procured on all the different kinds of deposits in all depths and at great distances from qceax 
continental land. This may be accounted for by the continental conditions being carried 
far to the north as above suggested, but it appears to me to be likewise due to the 
greater abundance of food that falls to the bottom in this region, arising from the 
large numbers of Plankton organisms frequently killed at the surface owing to the 
mixing which takes place in these latitudes of surface currents from different sources 
and of very different temperatures. There is a parallel to this in the Northern 
Atlantic and Northern Pacific, though, owing to the distribution of the land masses,
