The Classification of Protozoa 107 



silicoflagellates, now considered a subdivision of the Chrysomonadida, 

 appeared as a separate order. The Order Phytoflagellida included groups 

 now separated as the Orders Phytomonadida and Chloromonadida. The 

 gregarines, coccidians, and haemosporidians were assigned to separate 

 orders in the Telosporidia.

 Subclass 2. Suctoria 



The system of Dofiein (7) differed in several respects from that of 

 Calkins. The phylum was divided into two subphyla, Plasmodroma and 

 Ciliophora. The "Infusoria" disappeared, the Ciliata and Suctoria being 

 advanced to classes of Ciliophora. In addition, the Foraminifera and 

 Mycetozoa were recognized as orders of the Rhizopoda, and the Tricho- 

 nymphidae were listed as an appendix to the Mastigophora.
