and constitute the type of the genus. Beijerinck (1906, p. 200) identi- 

 fied Sarcina ventriculi. Vuillemin (1913, p. 525) proposes that this 

 genus should be a ^'Genus conservandum." 



Buchanan (1915, p. 10) discussed in detail the validity of the generic ' 

 name and concluded the type should be Sarcina ventriculi Goodsir. 

 Later (1917, p. 614) he included it as the third genus of the tribe Mic- 

 rococceae with the following description: 



Saprophytes or facultative parasites. Division occurs under favorable con- 

 ditions in three planes, producing regular packets. Usually Gram-negative. 

 Growth on agar abundant with formation of yellow pigment. Dextrose broth 

 slightly acid, lactose broth generally neutral. Gelatin frequsntly liquefied. 

 Nitrates may or may not be reduced. 



The same disposition and practically the same diagnoses have been 

 used by Winslow et al. (Committee Soc. Am. Bact., 1917, p. 559, 

 1920, p. 208), Castellani and Chalmers (1919, p. 925) and Bergey, 

 et al. (1923, p. 70). 



Sarcinacoccos. According to Enlows (1920, p. 81) this casual name 

 was used by Billroth (1874, p. 8) for one of the growth forms of his 

 Coccohacteria septica. 



Sarcinaglobulus. A generic name used by Poulsen, (1879, p. 232). 

 Enlows (1920, p. 81) gives the following as the description used: 



Schizophj^tarum corpora perpava hyalina e cellulis incoloribus minimis 

 composita formans. Cellulae plantae vivae vix conspicuae reagentibus chemi- 

 cis additis apparent. Divisionis modus ut in Sarcina, quacum maximam simili- 

 tudinem habet. Ab hoc genere eo differt, quod non fasiculos hexaedricos sed 

 globulos vel flebas subisodiametricas vel irregulares rotundatas format. 

 Nucleum cellularum non observati. Species adhus una cognita, scil. 



Type species (monotypy). S. punctum. Char, gen.: Magn. 2 to 200/^. la 

 limo putido litoris freti cresund prope Haunias legi. 



The position and status of this genus is uncertain. 



Sarcinastrum. A generic name proposed by Lagerheim (1900, p^ 

 280) for an organism Sarcinastrum Urosporae found producing galls 

 upon the seaweed Urospora mirabilis. The following description of 

 the organism is given. 



Die zu Stiibchen ausgewachsenen Coccen erzeugen wahrscheinlich durch langs-^ 

 spaltung Kolonien, bestehend aus parallelen Staben, die zu einer runden, 

 gebogenen Scheibe angeordnet sind. Diese Scheibe wird spiiter durch fort- 

 gesetzte Langsteilung der Stabe balbkugelig, zuletzt fast hohlkugelig. Nach- 

 dem die Kolonie eine gewisse Grosse erreicht hat, tritt Quertheilung der Stabe 

 zu Coccen ein; die Kolonie besteht schliesslich aus einer sehr grossen Anzahl
