It is necessary to bear in mind the normal structures and the fact that, until the parasite reaches a considerable size and has a very sharply defined cyst wall, pigment, of the characters belonging to the species of parasite concerned, is Fig. 32.

Zygotes of crescent tertian shew, when young, a clump of pigment resembling black pepper grains (Fig. 33). 2. Zygotes of simple tertian shew yellowish or golden pigment in wisps (Fig. 33). 3. Zygotes of quartan shew rather coarse pigment in a clump (Fig. 33). The older zygotes (40-60^) are indistinguish- able as regards the species of parasite concerned. They may shew :— 1. A very clear and distinct cyst wall (ad- ventitious). 2.
