Notes

Cinetozona pyriformis n. g., n. sp. is a very small scuticociliate recently found in a freshwater artificial pond in Madrid, Spain. This new ciliate is here described using silver impregnation techniques. C. pyriformis bears a girdle or cilia near the equator of the cell, similar to the genus Urozona Schewiakoff, 1889, while the oral structures resemble those in the genus Cinetochilum Perty, 1852. The ciliate's systematic position is discussed, and its inclusion in the family Cinetochilidae is proposed.
