De Toni and Trevisan (1889, p. 939) separated the various 

 tribes and subtribes of their subfamily, Baculogenae in the fol- 

 lowing manner: 



Key to Tribes and Subtribes of Baculogenae. DeToni and Trevisan 



A. Bacilli and cocci naked, never with a capsule Tribe I. Bacilleae 



I. Producing endospores. 



1. Division longitudinal Subtribe 1. Pasteurieae 



2. Division transverse. 



a. Rods united into a reticulate coenobium 



Subtribe 2. Thiodictyeae 

 h. Rods not united into a reticulate coenobium. 



(1) Hods never spiral Subtribe 3. Eubacilleae 



(2) Rods spirally bent Subtribe 4. Spirilleae 



II. Producing arthrospores Subtribe 5. Pacinieae 



B. Bacilli and cocci surrounded by a special membranous or gelatinous 



capsule. Tribe II. Klebsielleae 



I. Rods straight or curved, never true spirals. 



Subtribe 1. Euklebsielleae 

 II. Rods spirally twisted Subtribe 2. Myconostoceae 



Of these names Pasteurieae may be discarded because Pas- 

 teuria is probably a protozoan. Thiodidyeae includes forms
