108 The Classification of Protozoa 



Class 1. Ciliata 



Order 1. Holotricha 

 Order 2. Heterotricha 

 Order 3. Oligotricha 



Order 4. Hypotricha 

 Order 5. Peritricha 

 Class 2. Suctoria 



Hartmann (12) recognized five orders of Neosporidia among the Spo- 

 rozoa. To the Subclass Flagellata, was added the Order Binucleata to in- 

 clude some of the Trypanosomidae and Haemosporidia as supposedly 

 binucleate organisms. Since the binucleate nature of these organisms has 

 never been established (21), the Order Binucleata has not been accepted 

 by later workers. 



Subphylum 1. Plasmodroma 

 Class 1. Rhizopoda 



Order 1. Amoebina 



Order 2. Mycetozoa 



Order 3. Foraminifera 



Order 4. Heliozoa 



Order 5. Radiolaria 

 Class 2. Mastigophora 



Subclass I. Flagellata 

 Order 1. Protomonadina 

 Order 2. Polymastigina 

 Order 3. Binucleata 

 Order 4. Euglenoidea 

 Order 5. Chromomonadina 

 Order 6. Phytomonadina 



Subclass 2. Dinoflagellata 

 Order 1. Adinida 

 Order 2. Dinifera 



Subclass 3. Cystoflagellata 



Class 3. Telosporidia 

 Order 1. Coccidia 

 Order 2. Gregarinida 



Class 4. Neosporidia 

 Order 1. Myxosporidia 

 Order 2. Microsporidia 

 Order 3. Sarcosporidia 

 Order 4. Actinomyxidia 

 Order 5. Haplosporidia 

 Subphylum 2. Ciliophora 



Class 1. Ciliata 



Order 1. Holotricha 

 Order 2. Heterotricha 

 Order 3. Oligotricha 

 Order 4. Hypotricha 

 Order 5. Peritricha 



Class 2. Suctoria 



In the system of Minchin (16) the subphyla Plasmodroma and Cilio- 

 phora were dropped and the Class Infusoria restored. The Heliozoa and 

 Radiolaria were recognized as subdivisions of the Actinopoda. In the 

 Ciliata, erection of the Sections Aspirigera and Spirigera stressed dif- 

 ferences in adoral ciliation.
