Using determinations of physiological reactions, nocardiophage sensitivities and recombinant production, subcultures of the type strains of Jensenia canicruria Bisset and Moore were found to be identical to subcultures of the type strains of Nocardia erythropolis (Gray and Thornton) Waksman and Henrici. It was suggested that under the rules of nomenclature, J. canicruria should be reduced to synonymy with N. erythropolis. The inclusion of N. erythropolis in the synonomy of Mycobacterium rhodochrous (Over-beck) Gordon and Mihm was rejected by the authors owing to differences between strains included in the synonymy of M. rhodochrous and the strains of N. erythropolis examined.

The name “Mycobacterium aquae Galli-Valerio” has been applied for a number of years to slowly growing amidase negative, scotochromogenic mycobacteria isolated from tap water or clinical specimens. This name has not been validly published, and the only extant culture representing the strains originally carrying that name has been found to be a member of the rapidly growing species M. smegmatis (Gordon and Smith 19 5 5). Examination of the type strain of M. gordonae Bojalil (1962) has demonstrated this organism to be very similar to the hypothetical median strain of the slowly growing “aquae” strains and these organisms should be considered members of the species M. gordonae Bojalil.

Neisseria catarrhalis differs from the type species of the genus Neisseria and six other species of this genus. It is proposed that this organism be transferred to Branhamella gen. nov., with the type species Branhamella catarrhalis (Frosch and Kolle) comb. nov. (Basionym Mikrokokkus catarrhalis Frosch and Kolle 1896, 154). Strain Nell (American Type Culture Collection no. 25238) is proposed as the neotype strain.

A new species of nonphot ochromogen mycobacteria is described. Most of the strains examined have been isolated from man; however, because of their lack of relationship to human disease, the name Mycobacterium triviale Kubica is proposed. The physical and biochemical characteristics, serologic activity, and thin layer chromatographic pattern of this new species serve to distinguish it from other nonphotochromo-genic mycobacteria in Runyon’s Group III.

Oral strains of Leptotrichia buccalis (Robin) Trevisan 1879, 138 (Basionym Leptothrix buccalis Robin 1853, 394) were found to be Gram-negative, on the basis of cell wall morphology and chemical composition. The G-C ratio 34 mole per cent places L. buccalis in a group with the genera Sphaerophorus and Fusobacterium in the family Bacteroidaceae.

A flagellated coccus is described which has a DNA base composition (G+C), morphological and physiological characteristics associated with the genus Micrococcus. The organism was isolated from the gut content of a gypsy moth, Porthetria dispar (L.), larva. The characteristics are markedly different from those of previously described species and thus a new species, Micrococcus diversus, is proposed.

Request for an Opinion from the Judicial Commission designating the type species of the genus Enterococcus Thiercelin and Jouhaud 1903, 686 as Enterococcus faecalis (Andrewes and Horder) Kalina 1968, 11.

Ascriptions of authorship to Dorothy F. Holland of names of species of bacteria in all seven editions of Bergey’s Manual of Determinative Bacteriology are incorrect. The names were not validly published.

A review of the nomenclatural status of the species of the genus Streptomyces which are reported in the literature as producing the antibiotic oxytetracycline.

Frankiaceae fam. nov. is proposed with the type genus Frankia. It includes in the genus Frankia one new combination, F. elaeagni and six new species, F. discariae, F. casuarinae, F. coriariae, F. dryadis, F. purshiae and F. cercocarpi.
