It will be noticed that there is an important difference in the geographical and 

 bathymetrical distribution of this group of Protozoa from what obtains in the case of the 

 Metazoa considered in the previous lists. 179 species or 82 per cent, of the total number 

 recorded from the Kerguelen Region have also been found within the tropics and in the 

 extra-tropical regions of the Northern Hemisphere, and the majority of these species have 

 a wide range in depth. The peculiar habits of the group as well as its antiquity possibly 

 explain this distribution. 



LIST VII/. 

 Looking upon the distribution of varieties as distinct from that of the species to 

 which they belong, the following shows the distribution outside this area of tlie 8 varieties 

 represented in the area under consideration : — 



Bilocidina depressa, var. raurrhyna — North, tropical and South Atlantic, North, tropical and South Pacific, 1100 to 2425 

 fathoms. 

 ,) „ var. serrata — North and tropical Atlantic, North, tropical and South Pacific, 580 to 2350 fathonis.
