The two following species are true Rissoce, characterized by the 

 simple aperture, which is not channeled in front, and by the absence 

 ef the calcareous appendage to the operculum. Many species of 

 small shells have been inaccurately referred to Rissoa, some of which 

 belong, however, to entirely different famihes.
