The Parameciina typically have a deeper oral cavity, with peniculi mainly forward of the mouth, and the paroral membrane reduced, though still present throughout interphase.
The peniculids were first defined by Fauré-Fremiet in 1956.

They consideredthe peniculids in the class Nassophorea, owing to ultrastructuralpeculiarities such as the presence of nematodesmata, which was considered to indicate the cyrtos was secondarily absent.

El Parameciina tiene típicamente una cavidad bucal más profunda, con el peniculi principal delantero de la boca, y la membrana paroral reducida, aunque todavía presenta a través de interfase.
El Peniculids primero fue definido por Fauré-Fremiet en Corliss, 1956, como uno de tres suborders de los hymenostomes, que ahora se tratan como subclases del Oligohymenophorea.
Consideraban los peniculids en la clase Nassophorea, debido a particularidades ultraestructurales tales como la presencia del nematodesmata, que era considerado indicar que los cyrtos estaban secundario ausentes.

 nassophorea
These are usually small and ellipsoid or crescent shaped, with the right side of the body curved outward, and generally have a rigid pellicle.
As first defined by Small & Lynn in 1981, the Nassophorea also included the peniculids and, in a separate subclass, the hypotrichs.
More recent schemes restore these to their earlier positions, leaving this group a relatively small collection of less well-known forms.
