490 GENERAL SYSTEMATIC BACTERIOLOGY 



Type species S. egens (Bacillus egens Stoddard) as described by (Stoddard 

 (1919a)). Splits glucose, laevulose, mannose, maltose, dextrin, glycogen, inosite 

 and glycerol. Does not sporulate on six days' incubation in inspissated serum. 



Streblothrichia. A generic name used by Guignard (1890, p. 142) 

 for a species of marine micro5rganism Streblothrichia Bornetii, which 

 he placed with the bacteria. The organism was found in rock fissures 

 by the ocean. It shows certain relationship to Nostoc in habitat 

 and to Rivularia in manner of growth. No heterocysts or sporocysts, 

 however, are formed. Migula (1900, p. 1039) gives the following 

 description : 



Diese neue Bakteriengattung bildet kleine farblose bis stecknadel grosse 

 Zoogloen von charakteristischem Bau, .... In der gemeinsamen Gal- 

 lerte verlaufen, von dem gemeinsamen Anheftungspunkte ausstrecklend, zarte 

 Iju dicke Bakterienfaden, die anfanglich dicht gedrangt und gerade, spater gewin- 

 den sind und namentlich in der Peripherie der Zoogloea dicht und regellos durch- 

 einander gewirrt erscheinen. Diese Faden sind aus annahrend isodiame- 

 trischen Gliedern mit fein granuliertem Inhalte zusammengesetzt und haben eine 

 ziemlich dicke Membran, die in der gelatinosen Grundmasse mitunter schwer 

 zu erkennen ist. 



The name is rejected by Erwin F. Smith (1905, p. 174). This is a 

 doubtful bacterial genus. 



Streblotrichia. A variant spelUng of Streblothrichia used by Enlows 

 (1920, p. 88). Probably a typographic error. 



Streptobacillus. This name has occasionally been used as the 

 designation of a form genus. Maggi (1886, p. 173) designated thus a 

 growth form of Bacillus. Migula (1900, II, p. 374) credits the name 

 Streptobacillus pseudotuberculosis rodentium to Preisz (1894, p. 231). 

 An examination of this paper fails to show however any use of Strep- 

 tobacillus as a generic name. The nearest approach is the following 

 statement : 



Nous proposons de denominer cette maladie la pseudotuberculose des ron- 

 geurs (pseudotuberculosis rodentium) et d'appeler avec M. Dor Streptobacille 

 son agent producteur, car ce terme rappelle un des caracteres importants de ce 

 bacille. 



Streptobazillus ulceris mollis was described by Unna (1892, p. 485) 

 from soft chancres. 



Ucke (1898, p. 996) named an anaerobe from the soil Streptobacillus 

 terrae. 



The organism which is responsible for acid production in the Egyp- 

 tian sour milk beverage is termed Streptobacillus lebenis by Rist and
