ANNOTATED 

 SYSTEMATIC LIST 



The following list is arranged according to the 

 classification used in The Ciliated Protozoa (Cor- 

 liss, 1961), with modifications based on more 

 recent revisions. No ranges are given since 

 most species are cosmopolitan, their distribu- 

 tions depending more on microhabitat than on 

 macrodistributional factors. Notes on system- 

 atics and ecology are given when they are im- 

 portant in identification of the taxa. Important 

 papers on a given family are also mentioned 

 (see Selected Bibliography). 



Class CILIATA 



Order Gymnostomatida 



Family AMPHILEPTIDAE Butschli, 1889. 

 Four genera with marine representatives: Am- 

 philept2is, Hemiophrys, Litonotris, and Loxophyl- 

 lum; all free-living and benthic. See Kahl 

 (1931) and Canella (1960). 



Family CHLAMYDODONTIDAE Stein, 1859. 

 At least eight genera with marine representa- 

 tives: Atopochilodon, Chilodonatella, Chilodo- 

 nella, Chlamydodon, Chlamydonella, Lynchella, 

 Odontochlamys, and Parachilodonella. Free-liv- 

 ing and benthic. See Dobrzanska-Kaczanowska 

 (1963), Dragesco (1966, 1967), and Deroux 

 (1970). 



Family COLEPIDAE Ehrenberg, 1838. Free- 

 living, widespread. Two genera: Coleps and 

 Tiarina; both marine. See Kahl (1930). 



Family DIDINIIDAE Poche, 1913. Ten gen- 

 era described, mostly marine: Acropisthium, 

 Askenasia, Choanostoma, Ctenoctophrys, Cyclo- 

 trichium, Didinium, Liliimorpha, Mesodinium, 

 Monodinium, and Zovotrichium. Mesodinium 

 widespread and ubiquitous; planktonic, but also 

 occurs near substrata. See Kahl (1930). 



Family DYSTERIIDAE Claparede and Lach- 

 mann, 1858. Free-living and benthic, or ecto- 

 commensal on crustaceans and fish. At least 

 eight genera with marine representatives: 

 Brooklynella, Dysteria, Hartmannula, Mirodys- 

 teria, Paratrochilia, Sigmocineta, Trochilia, and 

 Trochilioides. See Jankowski (1967a). 



Family ENCHELYIDAE Ehrenberg, 1838. 

 Free-living, widespread. This is a large, loosely 

 defined family in need of serious systematic re- 

 vision. Genera with marine species: Chaenea, 

 Chilophrya, Enchelyodon, Enchelys, Helicopro- 

 rodon, Holophrya, Ileonema, Lacrymaria, Lagy- 

 nurus, Longitricha, Microregma, Nannophrya, 

 Pithothorax, Placns, Plagiocampa, Platyophi-ya, 

 Rhopalophrya, and Spasmostoma. See Faure- 

 Fremiet (1961c). 



Family LOXODIDAE Butschli, 1889. Four 

 genera with marine representatives: Ciliofau- 

 rea, Kentrophoros, Loxodes, and Remanella; all 

 free-living, benthic, usually among sand grains. 

 Kentrophoros is a ribbonlike psammolittoral 

 ciliate usually included in this family, but it is 

 of uncertain affinities since its cytostome has yet 

 to be described. Cnjptopharynx, usually placed 

 in the family CHLAMYDODONTIDAE also 

 keys out here. See Dragesco (1960). 



Family METACYSTIDAE Kahl, 1926. Three 

 genera: Metacystis, Pelatractus, and Vasicola. 

 Metacystis occurs regularly in tidal marshes. 

 See Kahl (1930). 



Family NASSULIDAE de Fromentel, 1874. 

 Five genera with marine species: Chilodontop- 

 sis, Nassnla, Nassulopsis, Orthodonella, and 

 Stomatophrya. Free-living. See Agamaliev 

 (1967) and Dragesco (1960). 



Family PRORODONTIDAE Faure-Fremiet, 

 1961. This family, split from the family 

 ENCHELYIDAE by Faure-Fremiet in 1961 

 (1961c), contains at least the following genera, 

 all with marine species: Lagytiophi-ya, Pro- 

 rodon, TrnchelophyUiim, and Urotricha. Free- 

 livmg, widespread. 



Family SPATHIDIIDAE Kahl in Doflein and 

 Reichenow, 1929. At least ten genera (listed 

 in Corliss, 1961). Free-living and benthic. See 

 Kahl (1930). 



Family STEPHANOPOGONIDAE Corliss, 

 1961. One genus, Stephanopogon, free-living in 

 marine sands and algal mats. See Dragesco 

 (1963b) and Borror (1965b). 



Family TRACHELIIDAE Ehrenberg, 1838. 

 At least three marine genera: Dileptiis, Para- 

 dileptxis, and Trachelitis; all free-living. See 

 Dragesco (1963a).
