Eatoniella atervisceralis

In the original description, Ponder described the species as follows: E. atervisceralis measures by . This species can be distinguished from E. pullmitra due to its smaller umbilicus, evenly convex outer lip, taller spire, and the colour of the animal, and from E. dilatata due to its narrow inner lip, oval aperture and rounded peristome. Live specimens of the species can be most easily identified due to the black visceral mass visible through the shell. ==Taxonomy==
