tions of "new" organisms to emphasize the 

 ability of the cultures to produce melanin 

 pigments, an important and characteristic 

 property for distinguishing and identifying 

 species of Streptomyces, as brought out in 

 the various editions of Bergey's Manual. In 

 spite of the fact that these descriptions of 

 "new" organisms had been undertaken for 

 the purpose of identifying antibiotic-pro- 

 ducing cultures, no attempt was miulc to 

 list any antibiotic for the various "new" 

 species; all one finds are such expressions 

 as: "strong repression," "weak activity," 

 "no activity." Even the antibiotic "al- 

 bomycin" that has been greatly publicized 

 by the senior author is not listed in this 

 I real ise; neither is the species .4. subtropicus, 

 which produces this antibiotic, described. 

 Very little effort has been made in creating 

 these species to compare the newly isolated 

 cultures with those previously described and 

 well known in the literature. Many of the 

 new descriptions remind one of known organ- 

 isms. 



For these reasons, this collection of "new" 

 species is listed here (Table 28) as incom- 

 pletely described, or at least as requiring 

 further information for proper identification.
