336 GENERAL SYSTEMATIC BACTERIOLOGY 



species previously termed Klebsiella crouposa or K. pneumoniae was 

 renamed K. Friedlanderi. According to De Toni and Trevisan 

 (1889, p. 1028) the diagnosis is as follows: 



Baculi recti, turn cylindracei apicibusque rotundatis, turn ellipsoideo-fusi- 

 formes apicibusque attenuatis, in articulati, hyalini, immobiles vel rarius mobiles; 

 plasma aequaliter diffusum. Filamenta flexuosa vel recta, cylindracea vel monili- 

 formia, articulata, a baculis temnogenesi transversali imperfecta adhue conjunctis 

 constitua. Cocci globulosi, e baculorum seu filamentorum transformatione orti. 

 Baculi, filamenta, cocci intra capsulas membranaceomucosas, rare firmas, 

 inclusi. Sporae (endosporae) in baculis provenientes. 



The generic description does not fit closely any of the species included 

 by De Toni and Trevisan as they are now understood. The genus is 

 divided into two species groups. "Species anthrophobiae," with four- 

 teen species, and "Species zoobiae," with three. Two species Kleb- 

 siella rhinosclcromatis and K. salivarius are credited to "Trevisan 

 1887." Of the species named in 1889, K. Friedlanderi (Friedlanders 

 pneumobacillus) and K. enteritidis are well known. This genus name 

 is rejected by Erwin F. Smith (1905), 



Vuillemin (1913, p. 525) has proposed that Trevisan's Klebsiella 

 salivarius (Diplococcus pneumoniae of Weichselbaum) be constituted 

 the type of a "Genus conservandum," with an emended diagnosis. 

 However, the generic name Diplococcus pneumoniae Weichselbaum 

 has priority, and Diplococcus {q.v.) should be used if the pneumococcus 

 is to constitute the type of the genus. 



As indicated by Enlows (1920, p. 50) the type species is Klebsiella 

 crouposa Trevisan. 



De Toni and Trevisan (1889, p. 1029) give the following synonymy 

 for Trevisan's Klebsiella Friedlanderi: 



Hyalococcus pneumoniae Schroeter (1886) 

 Pneumococcus Friedlander 

 Bacterium pneumoniae-crouposae Zopf. 

 Klebsiella crouposa Trevisan 1885 

 Klebsiella pneumoniae Trevisan 1887 



It is evident that the correct name for the type species therefore 

 is that of the Friedlander pneumobacillus. Its name is probably 

 either Klebsiella crouposa or Klebsiella pneumoniae. From the stand- 

 point of usage the latter is preferable. Klebsiella has priority over 

 Hyalococcus and Encapsulatus, both based on the same type species.
