328 GENERAL SYSTEMATIC BACTERIOLOGY 



Inasmuch as the description of the species is quite inadequate, 

 the genus name has not come into use. Its validity is doubtful. It 

 is rejected (1905) by Erwin F. Smith. 



Helikobacterium. Probably to be regarded as a variant of Heli- 

 cobacterium. It was used by Escherich (1886, p.2) in the combination 

 Helihohacterium zopfii. Enlows (1902, p. 47) states: 



Characterized by its spiral colonies on gelatin plates. As the gelatin liquefies 

 zoogloeae of spindle-shape are formed, which anastomose, covering the entire 

 surface of the gelatin, and consisting of "swarming" bacteria, spirilla, and watch- 

 spring-like threads. In older gelatin cultures round and elliptical forms in varied 

 grouping are found (diplococci, tetrads, chains, etc). He figures what he describes 

 as "spirochiiten" occurring in a milk culture of his Helikobacterium. 



Species. Thinks Bacterium zopfii Kurth belongs here and suggests the name 

 H. zopfii for it. In one paragraph he writes his genus Helikobacterium (Klehs), 

 probably referring to Helicomonaden Klebs. 



Helikomonas. A variant of Helicomonas used by German writers 

 as Escherich (1886, p. 2). 



Helobacteria. A name applied by Billroth (1874, p. 27) to the growth 

 form of his Coccohacteria septica in which sporulation occurred. The 

 genus is discussed and rejected by Cohn (1875, p. 188) and is rejected 

 by Erwin F. Smith (1905). The name has never been used in a strict 

 generic sense. 



Hemophilaeae. A name given by Winslow et al. (Committee Soc. 

 Am. Bact., 1920, p. 212) to a tribe with the genus Hemophilus. The 

 tribal description is: "Minute parasitic forms growing only in presence 

 of hemoglobin, ascitic fluid or other body fluids," 



The name should probably be spelled Hemophileae. The latter 

 spelling is used by Bergey et al. (1923, p. 268). 



Hemophileae. A corrected spelling of the tribal name Hemo- 

 philaeae, suggested by Bergey et al. (1923, p. 268). Two genera are 

 included. The description follows: 



Minute parasitic forms growing only in the presence of hemoglobin, ascitic 

 fluid or other body fluids, or in the presence of certain growth accessory sub- 

 stances found in sterile, unheated plant tissue (potato). Mon-motile. Gram- 

 negative. 



Hemophilinae. A name given by Buchanan (1918, p. 44) to the 

 second tribe of the Bacteriaceae with the description: "Strict parasites, 

 requiring hemoglobin or at least serum for their growth in media. 

 Gram-negative, Non-motile. Cells may be pleomorphic. Usually 

 very small. No spores."
