CERTAIN GENERA OF THE CLOSTRIDIACEAE 15 



Genus 5. Henrillus nov. gen. 



Clostridioideae that do not liquefy gelatin. They produce 

 acid and gas in meat medium. They clot milk readily and attack 

 many sugars, producing much acid. Gram-negative or gram- 

 positive slender rods with terminal oval spores. Their colonies 

 in deep agar are large, lenticular and opaque. Very common 

 in soil, often found in wounds, do not invade tissue. 



Type species H. tcrlius {Bacillus tertius Henry) as described 

 by Henry. Henry believes that the conception B. tertius applies 

 to a group and not to a species. His nine strains which may be 

 taken as a type split the monoses, bioses, mannose, xylose, starch, 

 dextrin, glycogen, salicin, amygdalin and mannitol. 



This type was described by von Hibler with the number IX. 

 Flemmg (Bac. Y), Rodella (1902) (Bac. Ill), Robertson (1916 a), 

 Mcintosh, Adamson (1919) and the Committee and Weinberg 

 and S^guin also describe it. Choukevitch (1913) identifies 

 spherical sporulating organisms with Rodella III. The original 

 Rodella III did not clot milk and should perhaps be associated 

 with Flemingillus. 



Genus 6. Flerningillus nov. gen. 



Clostridioideae that do not hquefy gelatin. They produce 

 little gas or acid in meat medium. They do not grow very 

 abundantly in milk or change it. They do not show any marked 

 tendency to split sugars. Slender Gram-negative rods with 

 oval terminal spores. Colonies in deep agar lenticular, may 

 show an areola of fine radiations. Frequently found in wounds, 

 not pathogenic for guinea-pigs. 



Type species F. cochlearius (Bacillus cochkarius Douglas, 

 Fleming and Colebrook) as described by the Committee. This 

 type is highly motile and it split none of the carbohydrates that 

 it was grown in. It was described as bacillus III type C by 

 Mcintosh. 



Bacillus C of Adamson (1919, p. 380) should be referred to this 

 genus. It is slightly motile. Mcintosh's Bacillus III A was 

 also considered by Adamson to belong in such a group as this. 

 It splits glucose and maltose only. We may, until the non-
