These Protozoa, Figs. io2,io2a,io3, 104 and 104A, are entirely parasitic and in the majority of cases live upon fishes. Dr. R. R. Gurly listed 102 hosts, fishes and other aquatic fauna, inhabited by them, either encysted beneath the skin, on the surface of the head and fins, or in the gills, mouth, eyes, gullet, air bladder, heart, liver, spleen, stomach, in- testines and almost every other part of the body. The effect of their presence is a breaking up of the parts, which undergo a vitreous degeneration, the growth of tumors and postules and ultimately the death of the FIG. 103.

Cyst in the tissues of the Air-bladder of a Tench. -i. Psorospores liberated from the cyst, highly magnified. They are usually amoeba-like microscopic organisms, which reproduce with- in or without the cyst or tissue cavity with those species which inhabit the surface; and constantly within the cyst with those which inhabit the cavities of the hollow organs of their hosts. Mention will only be made of those Myxosporidae of the orders Phtenocystida and Microsporidiida common to.
