(Original description) The smooth, white and shining shell is broadly fusiform.

The shell is broadly shouldered but tapering narrowly anteriorly.

The columella is slightly concave, bearing four strong plaits, the anterior one being almost vertical, the second less so, the upper two very transverse, the highest of all being at right angles to the columella.

The outer lip is curved, very heavily thickened, crenulated on the inner edge by about a dozen rather irregular denticles.
