The smooth, little shell has a depressedly conical shape. It has a profound but narrow umbilicus. The shell contains 5 to 6 whorls that increase rapidly in size.They are separated by impressed sutures. The apex is minute. The body whorl is obtuse-angulate at the periphery. The aperture is round. The columellar margin contains a callus. The colour of the shell is a pale carnation or flesh-colour in hue. Inside the aperture there is a deeper shade of the same colour, painted with fillets spirally or ochre-brown beaded with white.[4] DistributionThis marine species occurs off Mozambique and South Africa. It has also been reported in the Gulf of Oman.[5] and off Sri Lanka.[6] References1. ^1 Bouchet, P. (2012). Ethalia carneolata Melvill, 1897.
