Mouth, contractile vacuole and macronucleus visible. The network of fibers in the peristomal region is much coarser and less extensive than in A. in\tili and T have never observed any fibers (interstrial?) between the lines of cilia on the body surface. The fine fibrillar connections between the outer and inner dorsal rows of peri- stomal cilia seem to be lacking in A. isscli. Instead the outer dorsal peristomal fiber dips down and forward to join the end of the inner dorsal peristomal fiber just ventral to the mouth. The fibers of the ciliary system seem to be all interconnected in A. isseli through the peristomal net system. The whole fibrillar organiza-.
