GENERAL SYSTEMATIC BACTERIOLOGY 489 



Usually parasitic, cells as a rule in irregular groups or short chains, rarely in 

 true packets, usually Gram-positive. Growth fair to good on the surface of arti- 

 ficial media. Sugars as a rule fermented with acid. Gelatin commonly lique- 

 fied. Nitrates may or may not be reduced. Pigment orange or white. 



It is probable that the genus should be divided upon the basis of pigment 

 production into two genera, Staphylococcus and Albococcus, or perhaps these 

 should rank as subgenera. 



The type species is Staphylococcus aureus Rosenbach. 



Winslow et al. (Committee See. Am. Bact., 1917, p. 558, 1920, p. 

 207), used practically the same description, as did Bergey et al. (1923, 

 p. 24). 



It is probable that Staphylococcus is a valid generic designation, with 

 Staphylococcus aureus Rosenbach the type. 



Staphylokokken. A variant spelling of Staphylococcus (Heim, 

 1911, p. 249). 



Staphylokokkus. A variant spelling of Staphylococcus used by 

 various German writers. 



Stigmatella. A generic name proposed by Berkeley and Curtis 

 (1857, p. 313) and described by Berkeley (1874) for an organism grouped 

 with the Hyphomycefes. Saccardo (1886, IV, p. 679) gives the follow- 

 ing description: 



Sporodochia superficialia, globosa, compacta. Hyphae seu sporophora arete 

 fasciculata, filiformia continua, simplicia vel furcata (flexuosa). Conidia magna, 

 globoso-ellipsoideae, continua, hyalina per caudam subpersistentem cuspida- 

 tam sporophoris haerentia. Genus distinctum, sed quo ad locum systematicum 

 dubium, hinc Aegerliae hinc Naemateliae subaffine. De identitate Sphaerocrea- 

 tis cum Stigmatella nullum mihi est dubium. 



The genus is included under the Tuberculariae mucedineae, Amero- 

 sporae. 



Thaxter (1892, p. 339) concluded that this name is a synon3Tii of 

 Chondromyces B. and C. and included this genus in his family Myxo- 

 bacteriaceae. The type species is Stigmatella aurantiaca B. and C. 



Stoddardillus. A name proposed by Heller (1922, p. 19) for the 

 eleventh genus of the Clostridioideae with the following description: 



Clostridioideae of energetic growth habit that liquefy gelatin, but do not pro- 

 duce HaS demonstrable by a lead-acetate-paper test in blood broth. Produce 

 abundant gas but little acid in meat medium. Grow very shyly or not at all in 

 milk. Attack a few sugars, but do not produce much acid. Short chunky Gram- 

 positive rods which do not form spores. Colonies in deep agar large, lenticular 

 and opaque. Not easily distinguished from Welchillus. May invade tissue, 

 causing considerable destruction of muscle but no foul odor. One strain, reported 

 from a case of human gas gangrene.
