A similar process of sporozoite-formation was seen in the sporesinfesting the testis where, in one ofthe fish examined, almost everyspore was in some stage cf repro-duction. Here also the spores werefound to have a capsule or cystabout them. The capsules are spher-ical and no larger than the longaxis of the spores. The protoplasm spores from the testis (A to I), end from the intestine (J and Ki. The cyst (X) is absent in the first Segregates in a thin deeplylatter. Camera drawing, x 4000 diameters. . . r stai
