The white colour of the colonies, the liquefaction of the 

 gelatine, and the motility of the organisms, show that the 

 bacterium has its closest allies in a group which consists chiefly 

 of harmless water bacteria. The tendency to produce slightly 

 curved or vibrion forms is characteristic of the phosphorescent 

 bacteria which form a subdivision of this group. The organism, 

 however, does not produce phosphorescence when grown in sea 

 water, in sea water with l°/ o peptone, in sea water gelatine or 

 upon sterile fish muscle. Excluding the phosphorescence, the 

 other characters show an affinity with the subdivision and, as far 

 as the rapid liquefaction of the gelatine is concerned, with one 

 of the members Bacillus luminosus, Beijerinck, which is identical 

 with an organism described by Katz as Bacillus argenteo- 

 phosphorescens liquefaciens and renamed Vibrio luminosus by 

 Lehmann and Neumann. As the organism does not appear to 

 have been previously described, I propose the name, following the 

 nomenclature of Lehmann and Neumann, Vibrio bresimoe (low 

 Latin — Bresmia, the bream).
