16 HILDA HEMPL HELLER 



proteolytic slender end-sporing rods have been carefully investi- 

 gated, include strains that spUt a few easily fermentable sugars 

 and do not produce much acid in genus Flemingillus, and those 

 that split many sugars and tolerate much acid in the genus 

 Henrillus. 



Choukevitch describes a number of organisms possessing a 

 similar lack of fermentative ability to Flemingillus. Possibly 

 his B. irregularis belongs here; Sireptobacillus anaerobicus-magnus 

 does not resemble this t3TJe morphologically, but does chemically. 



B. ventriosus of Tissier and B. gracilis-pittidus of Tissier and 

 Martelly resemble this type. Coccobacillus oviformis and B. 

 capillosus of Tissier resemble it in fermentative powers but 

 not in morphology. 



Genus 7. Vallorillus nov. gen. 



Clostridioideae that do not Uquefy gelatin. They produce 

 gas and acid in meat medium but no digestion. They clot 

 milk slowly and attack various sugars. Rather slender Gram- 

 positive rods with little or no tendency to form spores. Form 

 lenticular colonies, "coeurs jaunes," in deep agar. May invade 

 tissue, producing oedema and gas. Pathogenicity transitorj'. 



Type species V. fallax {Bacillus fallax Weinberg and Seguin) 

 as described by the Committee (p. 27), the type which ferments 

 glucose, laevulose and maltose. 



Henry regards this organism as capable of fermenting manj' 

 sugars and starch. 



Choukevitch (1911) describes under the name B. bifurcalus 

 gazogenes a large branching organism which has fermentative 

 reactions similar to Vallorillus, but can hardly be included in 

 the genus on account of its unusual morphology. 



Genus 8. Multifermentans nov. gen. 



Clostridioideae that do not liquefy gelatin. Produce gas and 

 acid in meat medium. Clot milk readih^, without stormy fermen- 

 tation. Rather small Gram-positive rods with oval central or 

 subterminal spores. Activelj' saccharolytic. Found occasion- 

 ally in wounds, not tissue invaders.
