SYNOPSIS. Clones of 3 strains of the ciliated protozoon Glaucoma chattoni were subjected to corticotypic analysis. In agreement with previous studies on Tetrahymena , many cortical features vary in a systematic way with the total number of ciliary meridians. Most strikingly, the positions of the contractile vacuole pore and the numbers of postoral meridians change in a regular progression, but the patterns of change are distinctive in different strains. Under the growth conditions employed the corticotypes (meridian numbers) in G. chattoni are much less stable than those in T. pyriformis and no preferential “stability sink” is apparent.
