x1v.1 Merrill and Wade: The Validity of Discomyces 61 
rejected de Toni and Trevisan’s objection that Meyen had given 
the name to another organism as an unreasonably strict interpre- 
tation of the principles of botanical nomenclature. On the other 
hand, for the rest of the group he rejected Streptothriz and 
accepted Nocardia. This subdivision of the group has been 
adopted in several American bacteriological textbooks. How- 
ever, Chester (16) adopted the first classification of Lehmann and 
Neumann, except that Oospora was replaced by Streptothriz 
Cohn. Clements(17) included these organisms among the Schizo- 
‘mycetes; he followed Migula’s earlier classification, except that 
Nocardia was substituted for Streptothrix Cohn, emend. Mig. 
Foulerton(22) argued that, since the other names that had 
been proposed had dropped out of use, only Streptothrix and 
Actinomyces remained to be considered. He chose the former 
because, although Corda had used it in 1834, it had become uncer- 
tain to what particular organism the term had been applied; 
further, a committee of the Pathological Society of London in 
1899 had recommended the term “streptotricosis” as the ap- 
propriate clinical designation for the infection. Musgrave and 
Clegg (46) acknowledged that N: ocardia was probably more 
strictly correct, but “chiefly because of usage, and therefore 
somewhat arbitrarily, tentatively accepted Streptothrix * * 
*”? They suggested the possible advantage of substituting an 
entirely new name, Carteria (Carterii, sic!), evidently hoping 
that by this means further controversy might be eliminated. 
Pinoy has divided the group into Nocardia, which is to include 
most of the species, and Cohnistreptothriz, said to be designed 
to replace Cohn’s invalid Streptothrix. The article that con- 
tains his argument is probably one by Pinoy and Morax, (52) 
which is not available to us. According to Chalmers and Chris- 
topherson(15) the characteristics of this genus are preference 
for anaérobiosis, difficulty of cultivation, and nonproduction of 
arthrospores; in it they include Cohn’s Streptothrix foerstert 
and Israel’s Actinomyces from man (Streptothriz israeli Kruse, 
1896). 
Vuillemin, (60) as a result of the adoption by the 1910 meeting 
of the International Botanical Congress at Brussels of a program 
for the next congress that included the determination of the 
point of departure for the nomenclature of the Schizomycetes 
and the elaboration of lists of nomina conservanda for these 
organisms, has recently published a revised generic classifica- 
tion, which was intended to be submitted for consideration at 
the scheduled London (1915) meeting of the congress. In an 
appendix to this work he includes the family Microsiphones,
