In studying the characteristics of several strains of the organism commonly called Torulk histolytica, some rather prominent structures were noted, the significance of which seems to have been overlooked in previous descriptions. The study of the nature of these bodies disclosed a sequence of changes in morphology which necessitates a revision of the classification of at least some of the members of this group. One of the strains studied was isolated on four occasions from the spinal fluid of a patient in the University of Iowa Hospitals. This man had symptoms indicative of lesions in the central nervous system for two years prior to admission in 1934. In January, 1936, his disturbance had neither progressed nor subsided. Another strain was recovered from the spinal fluid of a patient in the Minneapolis General Hospital in 1935. His illness, from onset to death in three months, was characterized by symptoms referable to the central nervous system and at necropsy these tissues exhibited typical lytic lesions. We are indebted to Dr. A. T. Henrici and Dr. N. H. Lufkin for the culture and history of this latter case. OBSERVATIONS Cultures of these two strains of organisms, when studied in the ordinary fashion, exhibited all of the described characteristics of Torula: reproduction by budding, no mycelium formed and glucose alone fermented, and without gas formation. However, 89
