26 HILDA HEMPL HELLER 



Hempl has described a similar organism not identical with 

 that of Tissier and Martelly (Organism II, which may be renamed 

 Martellillus proteolyticus) . Bacillus II of Chouke\'itch probably 

 belongs in this genus, as does von Hibler's bacillus XV. B. 

 sporogenes B, as described by Choukevitch also belongs here. 

 A rather shyly growing species sent me by Major Nichols which 

 was named B. hellonensis Saqu^pee, was apparently pure, non- 

 pathogenic, and referable to this genus. It was not the organism 

 described by Saquepee as B. hellonensis, nor did it resemble 

 other strains sent me by Saquep6e. Adamson describes two 

 species of this type. One under the name of B. hifermentans- 

 sporogenes, which is non-motile and does not spUt sugars, the 

 other under the name of "Central spore bacillus" which he 

 identifies as Mcintosh's type XII, which is motile and splits 

 glucose and maltose. The type species is, however, supposed 

 to be saccharolytic. Mcintosh's type XII (parasporogenes) 

 does not behave in my hands as does this latter type of Adamson's 

 and I should not include them in the same genus. INIcIntosh's 

 type XIII, a pathogenic proteolytic organism, should probabty 

 be placed here. Some of the organisms here listed are prob- 

 ably identical, but one is not warranted in so considering them 

 without a direct comparison of strains. Study of many strains 

 would probably necessitate the division of this genus into two, 

 on the basis of carbohydrate fermentation. 



This is one of the important groups that most need syste- 

 matic investigation. 



Genus 21. Recordillus nov. gen. 



Puirijicoideae that, though they sporulate, are exceedingly 

 delicate and soon die in meat medium and other media. Their 

 growth in meat medium resembles that of the organisms of 

 genus Martellillus; they do not produce much gas, they color 

 the meat particles a greyish color and form a blackish pigment. 

 Gram-negative rods with central or sub-terminal cocoon-shaped 

 spores. Parasitic forms which infect cattle in California and 

 Nevada. I venture to place such organisms in a separate genus 

 on account of their parasitic habit and on account of their
