 ether, chloroform and benzol; soluble (Hef- feran, op. cit., 1903, 529). Yellow pigment insoluble. Distinctive character: Milk becomes blood-red in 12 to 20 days. Non-pathogenic for mice (Fuller and Johnson, op. cit., 1899, 609). Optimum temperature, between 28° and 35° C. Aerobic (Fuller and Johnson, loc. cit.). Facultatively anaerobic (Hefferan, op. cit., 1903,530). Source : Isolated from red milk by Hueppe in Wiesbaden in 1886. Isolated from feces of a child by Baginsky (Cent. f. Bakt., 6, 1889, 137). Isolated from Ohio River water by Fuller and Johnson (op. cit., 1899, 609). Iso- lated from Mississippi River water by Hef- feran {op. cit., 1903, 456). Burri and Staub (Landwirtsch. Jahrb. d. Schweiz, 40, 1926, 1006) isolated an organism of this type from Emmenthal cheese; they regarded it as closely related to or possibly identical with this species. Habitat: Probably widely distributed in nature. 3. Brevibacteriiim fulvum (Zimmer- mann, 1890) Breed, 1953. (Bacillus fvlvus Zimmermann, Bakt. unserer Trink- u.

From dust and water (Dyar). Habitat: Water. 4. Brevibacteriuin insectiphiliiim (Steinhaus, 1941) Breed, 1953. (Bacterium insectiphilium Steinhaus, Jour.

L. noun insectum an insect; Gr. adj. philius friendly; M.L. in- sectiphilium friendly to insects. Rods, 0.8 to 1.2 by 1.0 to 2.8 microns, occurring singly. At times appearing almost as cocci or coccobacilli. Non-motile. Gram- positive. Gelatin stab: Liquefaction. Agar colonies: Light greenish 5^ellow, cir- cular, entire, raised, glistening, smooth, opaque. Agar slant: Filiform, raised, smooth, glistening, opaque growth.
