Subphylum INFUSORIA— Continued. 

 Class Suctoria — Continued. 



Family Podophryidae — Continued. 



The tentacles are prehensile and may be knobbed or pointed. Typ- 

 ical genus, Ephelota Str. Wright, 1858. 



Family Acinetidse. — ^Reproduction is typically by endogenous budding. 

 This may be simple or multiple. Swarm spores are formed, which 

 may be peritrichous, holotrichous, or hypotrichous. The individuals 

 are naked and stalked or thecate and either stalked or unstalked. 

 There are numerous tentacles, usually similar and knobbed. Typ- 

 ical genus, Acineta Ehrenberg, 1833. 



Family Dendrosomidae. — Suctoria that may be either simple or branched. 

 There are no stalks or theca. The numerous tentacles are similar 

 and grouped in tufts and are knobbed. Peritrichous swarm spores 

 are produced. Reproduction is by endogenous budding. Typical 

 genus, Dendrosoma Ehrenberg, 1838. 



Family Dendrocometidae. — Sessile forms, which rest upon the entire 

 basal surface or upon a raised portion which forms a stalk. The 

 tentacles are short and knobbed and numerous and may be distri- 

 buted over the entire apical surface or be localized upon branched 

 arms. Reproduction by endogenous spore formation, the swarmers 

 being peritrichous. Typical genus, Dendrocometes Stein, 1867. 



Family Ophryodendridae. — There are numerous long, sometimes knobbed 

 tentacles, supported upon proboscislike processes of the apical side. 

 Reproduction by endogenous budding with the formation of peri- 

 trichous swarm spores. Stalked or sessile. Typical genus, 

 Ophryodendron Claparede and Lachmann, 1858. 



SOME STANDARD WORKS ON THE PROTOZOA 



The following does not, by any manner of means, exhaust the 

 list of standard works on the Protozoa. Practically all of them 

 include an exhaustive and up-to-date bibliography, and they are 

 books that are more or less accessible to the average reader.
