Shell solid and very glossy. 4-5 slightly convex whorls, reasonably well defined although secondary spire callus fills the suture. Simple, rounded and glossy protoconch of about 1.5 whorls. Shell rounded, hardly shouldered. Columella strongly concave, parietal callus separated from the body wall, forming a deep and long false umbilicus, which is definetely wider than in E. balteata and E. glabrata. Labral denticle present but not very well developed. Anterior fasciolar groove deep and curved, fasciolar band smooth. Posterior fasciolar groove relatively shallow. Ancillid band well developed but comparatively narrow. The ancillid groove forms a clearly visible impression at the posterior margin of the ancillid band. Operculum chitinous, completely closing aperture. Colour bright orange, aperture white; completely white specimens also occur (Rios, 1990: 10). Large specimens reach a length of about 55 mm but average size is 35-40 mm.

E. lienardi differs from E. glabrata and E. balteata by its more rounded and glossy shell, its much wider false umbilicus, its much narrower ancillid band and its bright white aperture.

E. lienardi is distributed along the north and northeast coast of Brazil. De Jong & Coomans (1988: 89) reported two specimens from the west coast of Aruba. According to Rios (1990: 9), E. lienardi lives on sandy and calcareous algae bottoms at depths of 15 to 40 metres. In the State of Ceara (Brazil) it is usually found in the digestive tract of the fish named pira (Melacanthus plumieri), according to Rios (1990: 9). Discussion - E. lienardi generally lives in deeper water than E. glabrata and E. balteata. It is for this reason that it was once considered very uncommon. It is now found in quantities by Brazilian fisherman.
