Sometimes two or threeinfusoria inhabit the same cyst, the form of the younger differing fromthat of the grown individuals. The fishes soon appear completely ema-ciated, the skin becomes thickened where the parasite is encysted, a scumforms on the surface and deaths occur in ten days to two weeks. Pantotrichum lagenula (U. lagenula.)
