Haminoea

Haminoea is a genus of medium-sized sea snails or bubble snails, marine opisthobranch gastropod molluscs in the family Haminoeidae, the haminoea bubble snails, part of the clade Cephalaspidea, the headshield slugs and bubble snails.
Three different spellings (Haminoea, Haminea, Haminaea) were used for this genus over two hundred years. The ICZN finally made a decision that the correct spelling is Haminoea.
