A Note upon <i>Retortamonas rotunda</i> n.sp, an Intestinal Flagellate in <i>Bufo vulgaris</i>

Abstract

In Bufo vulgaris there is a small flagellate similar to species described from insects and the Brazilian cavy. Such flagellates were formerly placed in the genus Monocercomonas but the generic name has been amended to Retortamonas Grassi 1879 by Wenyon (1926). The toad flagellate which I name R. rotunda n.sp. differs in structure from Monocercomonas bufonis Dobell 1909, which Grassé (1926) has removed to the genus Tetramastix Alexeieff 1916.
