Velutinidae in the World Register of Marine Species

Velutinidae is a family of small sea snails, marine gastropod molluscs in the clade Littorinimorpha.[1][2][3]

The shell of these animals is very thin and delicate, and internal, completely covered by the mantle (which has fused lobes) so the appearance of these animals more closely resembles that of sea slugs rather than sea snails.
