GENERAL SYSTEMATIC BACTERIOLOGY 289 



of the filamentous bacteria, usually grouped under Trichobaderiaceae 

 and Chlamydobacteriaceae. 



Desmobacteries. The fourth order of bacteria, according to Maggi 

 (1886, p. 173), including the genera Bacillus, Actinobacter and Dispora. 

 No description is given. 



Desmobacterinae. An ordinal name used by Benecke (1912, p. 

 188) to include the single family Desmobacteriaceae. 



Desmobacterium. Included as a synonym of Bacillus by Klein 

 (1885, p. 37) in the statement '^Bacillus {Desmobacterium Cohn.)" 



Detoniella. A bacterial genus proposed by Detoni and Trevisan (1889, 

 p. 929) with the following diagnosis: 



Filamenta cylindrica articulata, simplicia, basi ab apice superior! distincta, 

 propter pulvinulum mucosum primitus affixa immobilia, serius libere natantia, 

 lente oscillantia et in strata varie implexa. Cocci constanter nulli. Multi- 

 plicatio baculogonidiis e vaginae apice egredientibus, primitus vivacissime 

 mobilibus, cito immotis. Arthrosporae 4-5 in singulis articulis baculiformibus 

 obvenientes. OBS. Genus a ceteris Kurthiensis arthrosporis in bucalis ortis 

 coccorumque constanti defectu primo intuitu probe distinguendum. 



It is included in the tribe Kurthieae Trevisan (q.v.) 

 The genus includes three species of which the first described De- 

 toniella ochracea (Roth) Tre\asan may be regarded as the type. The 

 organisms included are those which are generally listed with Lepto- 

 thrix and the genus may be regarded as a synonym of this term. 



Dialister. A name proposed by Bergey et at. (1923, p. 271) for the 

 second genus of the tribe Hemophileae with the description: 



Minute rod-shaped cells, occurring singly, in pairs and short chains. Non- 

 motile. Strict parasites. Growth occurs only under anaerobic conditions in 

 media containing fresh, sterile tissue or ascitic fluid. 



The only species known is Dialister pneumosintes (Olitsky and Gates) comb, 

 nov. 



Diaschizae. A subdivision of the group Schizomycetes coordinate 

 with Paraschizae proposed by Jennings (1899, p. 315) to include all 

 bacteria which multiply vegetatively by transverse division, 



Dicoccia. A genus of bacteria proposed by Trevisan (1889, p. 26). 

 De Toni and Trevisan (1889, p. 1034) give the following diagnosis: 

 "BacuH Klebsiellae, capsuHs, inclusi, plasmate polari-diblastico foeti; 

 sporae, ignotae. Ob^. Ut Pasteurella a Baciho, hoc genus a Klebsiella 

 distat." This genus is included in the tribe Klebsielleae Trevisan 

 (q.v.) and the subtribe Euklebsielleae. The cells resemble Klebsiella 

 Trevisan (q.v.) except that the cells show bipolar characters similar
