rule motile by means of polar fiagella, sometimes non-motile. Typically water 

 forms, though some species are intestinal parasites. 



Buchanan (1918, p. 175) and Bergey et at. (1923, p. 97) used this 

 designation for the third family of the Euhacteriales, including the 

 genera Vibrio. Spirillum and Paraspirillum. Castellani and Chalmers 

 (1919, p. 924) include this as the third family of the Euhacteriales 

 with the genera Spirosoma, Vibrio and Spirillum. 



Spirilleae. The name given by De Toni and Trevisan (1889, p. 

 1006) to a subtribe of bacteria belonging to the tribe BaciUeae. The 

 diagnosis given is " Baculi spiraliter torti. Endosporae." The follow- 

 ing genera are included: Spirillwn and Spiromonas. 



Spirillina. A group created by Perty (1852, p. 179) to include the 

 genera Spirillum and Spirochaete. The name has never come into 

 common use. 



Spirillineae. A subfamily name used by Rabenhorst (1865, p. 70) 

 to include the following genera: Vibrio, Spirillum and Spirochaeta. 

 The diagnosis given is: 



Spirillineae (Cohn in ed). Trichomata abbreviata vel elongata fiexuosa vel 

 spiraliter torta flexibilia et mobilis, plus minus distincte articulata, nuda vel moc 

 liquido hyalino achromatico involuta; articuli saepe leviter constrict!. 



Spirillobacteriaceae. A family name proposed by Orla-Jensen 

 (1921, p. 264) in the following statement: 



As to the family names of the bacteria, it will be convenient to let all of them 

 end in -Bacteriaceae, by which it will be seen directly what is in question. If 

 there are to be formed families ot the cocci and spirilla, they must consequently 

 be termed Coccobacteriaceae and Spirillobacteriaceae (or by the older name of Zopf , 

 Spirobacteriaceae) . 



Spirilloflagellata. According to Dobell (1911, p. 536), this name 

 was given to the group of spirochetes by Krzysztalowicz and Sied- 

 licki (1908). They include this group among the protozoan group 

 Alastigophora. 



Spirillum. A generic name first used by Ehrenberg (1830, p. 38) 

 to include the spiral bacteria. The species named is Spirillum volutans, 

 the Vibrio spirillum of Mllller (1786). 



Dujardin (1841, p. 223) gave the generic description: "Corps fili- 

 forme contourne en helice, non extensible quoique contractile." He 

 described three species, S. undula, S. volutans and S. plicatile. Perty 

 (1852, p. 179) included species descriptions of Spirillum volutans.
