einem der Enden, also ausserhalb der grossten Schwellung liegen. Bis jetzt 

 ist kein Vertreter dieser Gattung bekannt. 



Paracloster butyricus, the Granulohader immohilis of Grassberger 

 and Schattenfroh was later given as the type (1903, p. 60). 



This generic name has apparently not been used by other authors. 

 It is rejected by Erwin F. Smith (1905, p. 162). It may be regarded 

 as a synonym of Clostridium. 



Paracoccaceae. A subfamily of the Coccaceae proposed by Winslow 

 and Rogers (1905, p. 660) with the diagnosis: 



Parasites (thriving only, or best, on, or in the animal body), thrive well under 

 anaerobic conditions. Many forms fail to grow on artificial media, none produce 

 abundant surface growths. Planes of fission generally parallel, producing pairs, 

 or short or long chains. 



This diagnosis was emended in 1906, (p. 545), by the addition of: 

 ''never packets. Generally stain by Gram. Produce acid in dex- 

 trose and lactose broth. Pigment, if any, white or orange." In their 

 last contribution (1908, p. 240) the Winslows include the following 

 genera: Diplococcus, Ascococcus, Streptococcus, Albococcus and Auro- 

 coccus. 



It would seem that the subfamily name Paracoccaceae is invalid for 

 two reasons; it has the ending prescribed by the botanical code for 

 families and not subfamilies, furthermore, it is not formed as pre- 

 scribed in the code by the addition of an appropriate ending to the 

 name of one of the genera included. Inasmuch as no tribes are in- 

 cluded in the Winslow's classification, the tribal name Streptococceae 

 used by Trevisan might well be used in place of this subfamily. 



Parameningococcus. A casual name used by Dopter (1909, p. 74) 

 for a type of meningococcus. It is differentiated primarily by its 

 agglutination relationships. 



Paraplectrum. A generic name used by Fischer (1895, p. 141) 

 for non-motile rod-shaped bacteria which produce spores in the cell 

 tips, with consequent enlargement and formation of "drumsticks." 

 The description given is "Unbeweghch, ohne Geisseln, mit Endosporen 

 in einem kopfig aufgeschwollenen Ende." The type given is Para- 

 plectrum Peroniella, the Bacillus Peromelia of Klein (1889, p. 65). 

 The species mentioned later (1903, p. 61) is Paraplectrum foetidum 

 Weigmann. 



This genus has not been used by other authors. It is rejected by 

 Erwin F. Smith (1905, p. 162). It may be regarded as a synonym of 

 Plectridium.
