Capulus ungaricus

Capulus ungaricus, common name the bonnet shell, is a species of medium-sized sea snail, a marine gastropod mollusk in the family Capulidae, the cap snails.

Taxonomy
The original name of this species is Capulus ungaricus (Linnaeus, 1758). Later on, a few authors (e.g. Jeffreys, 1865, Thorson, 1941, Ziegelmeier, 1966, Lindner, 1977) changed the name erroneously in Capulus hungaricus.
