Abstract
THIS memoir deals with an important group of parasitic Protozoa, associated with disease in cold-blooded vertebrates, especially fishes, and in invertebrates, for instance, pebrine in silkworms. The spores of these Sporozoa are enclosed in a valvate shell (the valves of which are shown to arise from two or three special cells in the sporoblast), which contains, besides one or more masses of spore-plasm, one to four polar capsules, each with a spirally-wound filament. The assertions of some workers that the polar filaments can be extruded and subsequently retracted are not borne out by the author's experience. The morphology of the vegetative forms and spores and the multiplicative and propagative reproduction are fully described; some form of sexual reproduction is now known to occur in members of each of the three subdivisions of the Cnidosporidia.
