b. Species extending outside the slirdlow-tvater area of the Kerguelen Region. 



We come now to consider those species which have a wider distribution, and extend 

 into other regions of the ocean outside the area represented by these dredgings. The 

 number of such species is 169 (or 32 per cent, of the total number of species and varieties 

 found in these dredgings), and they may be divided into groups accoi'ding to their dis- 

 tribution in the tropical and extra-tropical regions of the ocean. Thus we find that of 

 these 169 species, 



100 species (or 60 per cent.) are known to occur in other regions south of the southern 



tropic (see List IVc.) ; 

 33 species (or 19 per cent.) are known to occur in regions both south and north of the 



tropics, but not in the intervening tropical zone (see 



List IVf/.) ; 

 20 species (or 12 per cent.) are known to occur in regions both south of and within the 



tropics, but not to the north of the northern tropic (see 



List IVe.) ; and 

 16 species (or 9 per cent.) are known to occur in regions both south of, within, and 



north of the tropics, and some of them may be regarded 



as cosmopolitan, or almost cosmopolitan (see List IV/!). 



We may now proceed to discuss in some detail the distribution of these 169 species, 

 according to the groups given above, indicating briefly the geographical and bath}-nietrical 

 distribution of each species outside the area repi'esented by these dredgings.
