GENERAL SYSTEMATIC BACTERIOLOGY 43 



bb. Cocci in mucoid matrix loosely joined in a plasmic filamentous series. 

 Cysts very tenuous, at length breaking apart. Special cysts none. 

 Subtribe Amoebobacteriae Trev. 



One genus only Amoebobacter Winogr. 



aa. Cocci in families of single or many layers, joined by mucus more or less 

 conspicuous. No cysts, endospores small, appearing in cocci. 



Tribe. Sarcineae Trev. 

 b. Cocci heaped up closely in firm mucous matrix. 



c. Cocci in solid irregular heaped families without order, densely 

 associated. Cocci divide in one direction. 



Thiopolycocc^is Winogr. 

 cc. Cocci closely associated in regular cubical families, dividing in 



three directions *Samna Goodsir 



bb. Cocci grouped loosely in mucous matrix. 



c. Cocci in fours in one layered families, in firm mucus, forming 

 parallelograms, loosely associated. Division in two planes. 



Lampropedia Schroet 

 cc. Cocci few in irregular families in firm mucoid membranes, pe- 

 riphery amorphous, associated without regular order. Divide 



in three directions Thiocapsa Winogr. 



ccc. Cocci in fours in small regular colonies, one layered, tenuous, 

 amorphous, scarcely breaking apart, loosely associated. Divide 

 in two planes. Pediococcus Lindner. 



aaa. Cocci in moniliform chains. Arthrospores large in the filaments or on apex. 



Tribe III. Streplococceae Trev. 

 b. Filaments produced in a membranous, gelatinous capsule : 



c. Capsules large, broad, lamellose.. . .Leuconostoc Van Tiegh. 

 cc. Capsules close, tenuous, not lamellose. 



Schuetzia Trev. 



bb. Filaments in a cylindrical sheath Perroncitoa Trev. 



bbb. Filaments naked: 



c. Pseudodichotomous. Arthrospores at tip of filaments. 



Babesia Trev. 

 cc. Simple. Arthrospores included in filaments. 



Streptococcus Billroth 

 emended Zopf. 

 4a. Cocci not in cysts, capsules or sheaths, nor in chains, with endospores. 



Tribe IV. Micrococceae Trev. 



b. Cocci in pairs Neisseria Trev. 



bb. Cocci associated in botryoid masses. . ..Staphylococcus Ogston 

 bbb. Cocci solitary or associated in amorphous zoogloeal masses. 



Micrococcus (Hallier) Cohn 



Hansgirg (1890) described two new bacterial genera which have been 

 uniformly ignored by subsequent writers. They are Mycacanthococcus 

 and Mycotetraedron, both from wine cellars. 



Baumgarten (1890) ignored the recognized rules of nomenclature in 

 the following classification:
