Transfer of the Widely Known "Spirotrich" Ciliate Bursaria truncatella O.F.M. to the Vestibulifera as a Separate Order There, the Bursariomorphida

The large ciliate Bursaria truncatella, so long considered a well-entrenched polyhymenophoran (spirotrich) member of the order Heterotrichida, is shown-by a study of silver-impregnated specimens-to possess only a false "adoral zone of membranelles" and thus not to be a heterotrich at all....

Description
Summary:The large ciliate Bursaria truncatella, so long considered a well-entrenched polyhymenophoran (spirotrich) member of the order Heterotrichida, is shown-by a study of silver-impregnated specimens-to possess only a false "adoral zone of membranelles" and thus not to be a heterotrich at all. In fact, its system of numerous vestibular polybrachykineties (as named here) requires its removal to the kinetofragminophoran subclass Vestibulifera. Here it most resembles the Colpodida, with its telokinetal stomatogenesis, etc. Support is given, however, to recognition of the separate order Bursariomorphida Fernández-Galiano, 1978, the vestibuliferan taxon erected for Bursaria by the author in a brief abstract of a year ago.
