234 GENERAL SYSTEMATIC BACTERIOLOGY 



has apparently not been used by other authors. It is not in correct 

 form. It is not derived from a generic name. 



Baculogene. A variant of Baculogenae used by Trevisan (1889, 

 p. 11) for the second suborder of the bacteria. Two tribes, Badllee 

 and Klebsiellee are included. 



Bakteriaceen. A name used by Hueppe (1886, p. 142) to designate 

 a "Gattung," of rod-shaped bacteria "mit Bildung endogener Sporen" 

 with the two subgenera Bacillus and Clostridium. It may be regarded 

 as a variant spelling of Bacteriaceae (q.v.). 



Bakterium. An aberrant form of the spelling of the genus Bacterium 

 used by some German authors as Hueppe (1891, p. 30). 



Balkanella. A generic name proposed by Castellani and Chalmers 

 (1919, p. 934) for the seventh genus of the tribe Ebertheae. It is defined 

 (p. 940): 



Definition. Ebertheae which ferment glucose completely with the production 

 of acid and gas; lactose not fermented. Milk clotted. 

 Type Species. Balkanella coagulans Castellani, 1916. 



It is also defined later (1920, p. 609). 



Batteriacee. A spelling of Bacteriaceae used by Italian writers, 

 particularly Lanzi (1876, p. 259) and Trevisan (1889, p. 1). 



Beggiatoa. A genus of bacteria created by Trevisan (1842, p. 56) 

 to include certain filamentous water bacteria. The generic definition 

 given is: 



Thallus 6 filis muco obvolutis, liberis, oscillantibus, simplicibus, elasticis, 

 rigides, arachnoideis, punctis asterisceformibus, primum in fascias dispositis 

 deinde inordinatis, notatis conflatus. 



Two species are described, the B. leptomitiformis and B. punctata. 

 The genus is included under Sub. IV, Lynghioideae, Tribus VII Lyng- 

 beae. The genus is variously placed by different authors with the Algae 

 and with the Fungi. Frequently it has been grouped with Oscillatoria 

 among the blue-green algae. The type species may probably be desig- 

 nated as Beggiatoa alba (Vauch) Trev. (named Beggiatoa punctata by 

 Trevisan in 1842). Kuetzing (1849, p. 237) included Beggiatoa as the 

 first subgenus of Oscillaria, using the following subgeneric description: 

 "Trichomata tenuissima laba, obsolete articulata vel continua, substan- 

 tia interna gonimica granulosa opaca." Seven species are described. 

 Rabenhorst (1865, p. 94) gives the following generic diagnosis:
