 * || |Form |||Cytoplasm |||Micro- nucleus |||Undulating Membrane |||Movement |||Development in Tse-Tse |||Susceptible animals
 * A. Trypanosoma Brucei Group, including T. Brucei—T. Gambiensi T. Evansi T. Equiperdum |||Polymorphic including short and stumpy forms ||Contains dark- staining granules |||Small and as a rule, at some distance from posterior end ||Well developed and in bold folds |||Active ||Completed in salivary glands |||Many species of mammals
 * B. Trypanosoma Pecorum Group, including T. Pecorum T. Simiæ |||Mono- morphic and small ||Non- granular |||Prominent and sub- terminal ||Well developed |||Active ||Completed in pro- boscis and hypo- pharynx. Never found in salivary glands |||Cattle—very fatal to pigs
 * C. Trypanosoma Vivaz Group, including T. Vivax T. Capræ T. Uniformi |||Mono- morphic ||Non- granular |||Large and terminal ||Little development and simple |||Very rapid ||Completed in pro- boscis and hypo- pharynx. Never found in salivary glands |||Affects only horse, cattle, goats and sheep. Ordinary laboratory animals immune
