From the water of Lac Tanganyika a new Salmonella type was isolated which has the following biochemical behaviour: No fermenta tion of adonitol, inositol, lactose, salicin, and sucrose. No production of indole, no liquefaction of gelatin (60 days at 20°C.), and no decom position of urea. Rapid fermentation of arabinose, dulcitol, glucose (with gas), maltose, mannitol (with gas), rhamnose, sorbitol, tre halose, and xylose. Positive reaction in Stern's glycerolfuchsin broth, formation of H2S. Positive reaction in liquid ammonium media con taining glucose and sodium citrate. Positive reaction in d-tartrate, mucate, or sodium citrate after 1 day, negative reaction in i-tartrate after 14 days. Nitrates were reduced, the Voges-Proskauer reaction was negative, and the methyl-red reaction positive. Serologically the type has the formula XVIII: ct: 1,7. Cross-absorp tion showed that the 0 antigen is identical with the 0 antigen of S. cerro. The H antigen of phase 1 (d) is identical with the H antigen of S. gaminara, phase 1, but the H antigen of phase 2 (1,7) is not identical with the H antigen 1,7 of S. gaminara as this type and sorne other types contain a special factor in phase 2, not expressed in the formula 1,7. The H serum of S. usumbura, phase 2, was absorbed completely by S. gaminara, phase 2. Cross-absorption showed that the H antigen of S. usumbura, phase 2, is identical with the H antigen of S. bredeney, phase 2.
