Ciliophora 423 



Zachaiias. Stylophrya Swarczewsky (203; Fig. 7. 55, H), Trichophrya Claparede and 

 Lachmann (79; Fig. 7. 55, F). 



Family 4. Discophryidae. Endogenous budding and capitate tentacles 

 are characteristic, although some species with pointed tentacles have been 

 assigned to the family (205). A lorica is lacking and a stalk may or may 

 not be present. 



The following genera have been referred to the family: Choanophrya Hartog (40), 

 Cyclophrya Gonnert (79; Fig. 7. 55, E), Discophrya Lachmann (205; Fig. 7. 55, A), 

 Echmophrya Swarczewsky (205; Fig. 7. 55, B), Rhyncheta Zenker, Rhynchophrya 

 Collin (40), and Thaumatophrya Collin (40). 



Family 5. Ephelotidae. These are stalked marine Suctorea with capitate 

 or pointed tentacles. Budding is typically exogenous and may be multiple. 

 A lorica may or may not be present. 



Two genera, Ephelota Wright (148; Fig. 7. 55, D) and Podocyathus Kent, have been 

 referred to the family. 



Family 6. Ophryodendridae. In these marine forms the tentacles are 

 concentrated on one or more mobile proboscis-like extensions. In addi- 

 tion to the usual type of larva, so-called vermiform buds, with no tentacles 

 or proboscis, may be produced by exogenous budding (149). 



The type genus is Ophryodendron Claparede and Lachmann (40, 149; Fig. 7. 55, I). 



Family 7. Podophryidae. Reproduction involves external budding, or 

 in some cases "fission" in which the two daughter organisms are almost 

 equal in size. A stalk and a lorica may be present or absent. 



The following genera have been referred to the Podophryidae: Lecanophrya Kahl, 

 Metacmcta Biitschli, Ophryocephalus Wailes, Paracineta Collin (40, 191; Fig. 7. 56, A), 

 Parapodophrya Kahl (79. 103; Fig. 7. 56, B), Podophrya Ehrljg. (59, 178; Fig. 7. 56, 

 C-H), Sphaerophrya Claparede and Lachmann (Fig. 7. 55, C), Spelaeophrya Stammer 

 (190), and Urnula ClaparMe and Lachmann.
