Notes
From an intermittent stream in College Station, Texas, a Paramecium was isolated that did not appear to belong to any recognized species. On the basis of nuclear and whole-body morphology, it can be assigned to the Paramecium aurelia species-complex, and it can be distinguished from other members of that complex on the basis of mating-type reactivity and isoenzyme patterns. These characteristics are felt sufficient to justify a new species assignment. The new species has been named Paramecium sonneborni n. sp. in honor of the late Dr. Tracy M. Sonneborn of Indiana University.
