Adult shells of this species attain a length of between 25 mm to 72 mm.
Many Epitonium species have shells that are very attractive and quite interesting in their structure. However this species is particularly striking, partly because it is very large compared with the great majority of other species within the genus, but also because the whorls themselves do not touch and so the shell is held together only by the well-developed ribs or costae.
