Each of these " sporoblasts" really contains two spores, the falciform spores (o), described in a typical sporozoonâin fact, the so-called sporoblast is a pseudo-navicella. Just as in the type referred to on the preceding page, so here, each falciform body gives rise to a little flagelloid creature. This form migrates from cell to cell of the animal's liver, encysting and produc-.
