Austialia, while the CoccoHthophores are important numerically 

 in the Indian Ocean, but not in the Southwestern Pacific seas; 

 and that the diatoms are more numerous in inshore waters, dino- 

 flagellates in offshore waters, except in colder waters south of 

 the sub-tropical convergence and possibly in regions of upwelling. 

 Because of the frequenc}^ of occurrence of non-phototrophic, 

 and facultatively heterotrophic microorganisms in phytoplankton 

 catches, the term "Protoplankton" is suggested to include the 

 net-phytoplankton, nannoplankton and the non-photosynthetic 

 protozoa and algae.
