A monster producing strain, called Tanna strain, could be isolated from the original stock of Paramecium calkinsi. The strain was consisted of monsters in 99% and normals in appearance in 1% under a given condition. The reverse situation was also true under another condition. Every animal from the strain can yield normals in appearance as well as monsters in variable proportions. The former divides more rapidly than the latter. The monsters behave abnormally in the growth and the macronuclear division, and fail to complete the binary fission. However, they can manifest their mating reactivities. The monsters were classified into six types (O, I-V) according to their abnormalities. Among them, the type IV which is found very frequently is consisted of L-shaped cells, which are classified into two cases in respect of the macronuclei. In one case, both the anterior and posterior halves of a cell bear a macronucleus in each. In the other case, the anterior half of a cell contains two macronuclei and the posterior half possesses non. Amoeba-like monsters, being the most conspicuous in shape, belong to the type V and often produce non-viable progeny. The monsters keep rotating near the bottom of the culture vessel, and retain 3-7 macronuclei which are markedly variable in form and size. Whether the mechanism for inducing monsters which Maly (1960b, 1961) has already found in the snaky strain of Paramecium aurelia is applicable to the present strain remains unsettled.
