    • n vorticella The typical genus of Vorticellidæ, having a retractile pedicel; the bellanimalcules. Many species are colonial inhabitants of both salt and fresh water; they are very numerous, and among the most elegant animalcules, like tiny transparent wine- glasses or bells borne on fine elastic stems, and continually waving about in the most graceful maimer, “as if they were ringing chimes for Undines to dance.” V. convallaria was described by Leeuwenhoek in 1675 as an “animalcule of the first size,” and called by Linnæus Hydra convallaria in 1758. It occurs in stagnant water and in infusions. See also cut under Infusoria.
