fast. Grows abundantly on agar at room temperature and at 37 C. 

 and produces a bright orange pigment. No polar bodies or granules. 

 Grows well in sugar broths and produces acid in dextrose and maltose. 

 Pigment production in 24 hours under aerobic and anaerobic condi- 

 tions at 18-25 C., but at 37 C. pigment in this length of time only under 

 aerobic conditions. Under anaerobic conditions, at 37 C. a trace of 

 pigment was evident after 10-14 days,. 



C. glandulae sp. nov. (Fig. 9). Small ovoid or coccoid bacterium. 

 Grows abundantly at room temperature or at 37 C. with a heavy creamy 

 consistency and brownish tinge. Gram-positive, nonmotile, nonspore 

 forming, does not liquefy gelatin. Grows abundantly in sugar broths 

 with uniform clouding. On Loeffier's serum abundant white glistening 

 growth occurs, changing to a brownish color after a few days. Pro- 

 duces acid in dextrose, saccharose and maltose vigorously and slight 

 acid in dextrin. Raffinose neutral. One strain on first isolation from 

 the gland on blood plates showed a remarkable likeness to B. tubercu- 

 losis in character of growth ; the colonies were dry and heaped up and 

 friable. This peculiarity did not persist in later transplants. Anti- 

 formin treatment showed these diphtheroids to be nonresistant. They 

 were not acid-fast. Isolated from glands of Hodgkin's disease. 



C. striatum (Chester) Eberson. Thick form, with clear cut bars. 

 Large and irregular granules visible. Heavy growth on serum with 

 pigment from white to yellow. Ferments dextrose and maltose, but 

 not saccharose. Gram-positive, does not form spores, nonmotile, does 

 not liquefy gelatin. Found in normal nasal mucus. 



C. segmentosum nom. nov. Nonmotile, gram-positive, nonspore- 

 forming, does not liquefy .gelatin. Polar bodies demonstrable. In 

 broth, growth is clear with sediment. Slight acid is produced in dex- 

 trose. Avirulent, from nasal mucus. 



GROUP 6. Gelatin-liquefiers. Type C. putidum sp. nov. (Fig. 12). 

 A slender, curved granular bacterium. It produces no spores, is 

 facultative, grows abundantly with confluent stringy mass on agar at 

 room temperature and at 37 C., giving off a decidedly offensive odor. 

 On Loeffler's serum, a heavy, white, moist and glistening mass. It 

 forms no acid in dextrose, lactose, saccharose, maltose, mannite, dex- 

 trin and raffinose. Isolated from ascitic fluid. 



GROUP 7. Anaerobic Diphtheroids Associated with Specific Clin- 

 ical Manifestations. Type C. typhi-exanthematici (Plotz). Small, 

 pleomorphic, gram-positive organism, not motile, not acid-fast. Most
