The taxonomic position of a group of freshwater bryozoans which produce consistently a peculiar type of floatoblast was examined, and the group was concluded to be a special form of Plumatella repens. This special form is characterized by the floatoblasts in which the naked capsular area on the dorsal side is narrower than in the typical form of P. repens. Ancestrulae of the two forms of P. repens are compatibly fusible. Each branch in a fused colony produces only a single type of floatoblast that is consistent with the intraspecific form of the branch. Hence, the two forms appear to be genotypical and not phenotypical. Pycnoblasts which have been assigned to Plumatella casmiana by previous workers, as well as some types of floatoblasts described by several authors, are considered identical with the floatoblasts of the special form of P. repens.
