The morphology is described of a scuticociliate, isolated from a sediment from Terra Nova Bay, Ross Sea, in the Antarctica. The studies, using light microscopy of silver impregnated specimens and by scanning electron microscopy, permit an assignment to the species, Uronema marinum. The main steps of micronuclear events during conjugation, that appear to be similar to the general plan of Tetrahymena and Paramecium aurelia complex, are shown. © 1990 Springer-Verlag.

Abstract
The morphology is described of a scuticociliate, isolated from a sediment from Terra Nova Bay, Ross Sea, in the Antarctica. The studies, using light microscopy of silver impregnated specimens and by scanning electron microscopy, permit an assignment to the species, Uronema marinum. The main steps of micronuclear events during conjugation, that appear to be similar to the general plan of Tetrahymena and Paramecium aurelia complex, are shown. © 1990 Springer-Verlag.
