Shell medium-sized to very large, subglobose, with a rather short spire; anterior siphonal canal recurved and short; columellar callus widely expanded onto the body whorl; labial varices often conspicuous; operculum more or less radially and concentrically striate, with a nucleus located at the middle of the internal margin.
 

Shell medium-sized, with a very large and inflated body whorl; sculpture exclusively spiral, with in some species several rows of nodules, usually at the shoulder and below. It is important to notice that these nodules are not obligatorily arranged on longitudinal columns, but often slightly staggered; labial margin often varicose outside, serrate internally; anterior canal narrow, strongly curved backwards, and open. The passing of the posterior siphon is often delimited by a strong denticle in the upper part of the lip.
 

Shell medium-sized, with a very large and inflated body whorl; like in Galeodea, the sculpture is spiral, with in some species several rows of nodules, usually at the shoulder and below; labial margin often varicose outside, serrate internally; labial varices often present; anterior canal short and open; no posterior siphonal notch.
