contains four strong, beaded, spiral cords with subequal interspaces, peripherally. Between these and the
suture, there are three slightly smaller similar cords, the space at the suture giving a channeled effect. On the base there are two less prominent cords and two wider nodulous ridges around the deep, rather narrow

aperture is circular. The thick outer
lip is fringed by the ends of the spiral cords. The axial
sculpture consists of numerous fine radial threads, most obvious in the channels between the cords. (described as ''Liotia lurida'')
