34 MANUAL OF DETERMINATIVE BACTERIOLOGY 



Class II. Adinomycetales 



Family 1. Spherophoraceae 



Genus a. Spherophorus 



In this outline, there are minor modifications in the names and in endings 

 given to the orders and tribes as compared with those given in his prehm- 

 inary papers. In the Order Micrococcales, Leuconostoc has been dropped 

 as a genus of the tribe Strepiococceae and Rhodococcns has been dropped as 

 a genus of the Tribe Staphylococceae. Veillonella proposed by Pr^vot as a 

 new genus in 1933 {loc. cit., p. 70) is included as a genus in the Family 

 Neisseriaceae. The spelling of Gajjkya is changed to Gaffkia. In the first 

 of Prevot's papers published in 1938 {loc. cit.), he proposes the following 

 new genera in the Order Bacteriales: Ristella, Zuherella, Capsularis, Euhac- 

 terium, Catenabacteriuni, Ramihacterivm and Cillohacterium. In the same 

 paper he also proposes the following new genera in the Order Actinomy- 

 cetales: Spherophorus, Spherocillus, Fusocillus, Pseudoleptothrix (withdrawn 

 in 1940 in favor of Leptotrichia Trevisan). He also accepts one genus 

 Actinohacterium (Haas, Cent. f. Bakt., I Abt., Orig., ^0, 1906, 180) not 

 previously mentioned in this discussion. With the single change noted 

 {Pseudoleptothrix to Lepototrichia) , the outlines of the genera in the orders 

 Bacteriales and Actinomycetales remains in the 1940 outline as it was given 

 in 1938. 



In the outline given in Prevot's Monograph {loc. cit., p. 17) one change is 

 made in the generic terms recognized in the r)rder Clostridiales from those 

 recognized in his second paper published in 1938, The genus name 

 Palmula proposed in 1938, having been found to l3e invalid because of prior 

 use for a genus of Protozoa, is changed to Acuformis. Other generic names 

 which appeared for the first time in the 1938 outline are Endosporus, 

 Inflahilis, Terminosporus and Caduceus. ]Velchia proposed by Pr^vot in 

 ^933 {loc. cit., p. 44) was previously proposed by Pribram (Jour. Bact., 18, 

 1929, 374) for the same group of anaerobic spore-forming rods. A third 

 order, Sporovibrionales, is proposed by Prevot in his Monograph {loc. cit., 

 p. 15) to include the family Sporovibrionaceae (Ann. Inst. Past., 64, 1940,
