Velutina is a genus of small sea snails, marine gastropod mollusks in the family Velutinidae. [2]
Species within the genus Velutina include:
The shell is thin, mostly external, calcareous, auriform, paucispiral and invested by a velvety epidermis. [9] The spire is lateral and diminutive. [9] The suture is well impressed. [9] The aperture is very large and rounded with the thin, almost continuous lip. [9] The columellar lip is a little reflected. [9] There is no operculum or umbilicus. [9]
The oval animal is convex above and little spiral. It has a large oblong foot. [9] The margin of the mantle is developed and more or less reflected over the edge of the shell. [9] The head is broad and depressed. [9] The two large tentacles are subulate, blunt, far apart, with eyes sessile on prominences at their outer bases. [9] The mouth has a short tube.
The formula of the radula is 2·1·1·1·2. [9] The central tooth is subquadrangular, multicuspid; the central cusps are very long and sharp; lateral teeth are multicuspid, marginals are narrow, with a few obsolete denticles on the margin. [9]
Species in the genus Velutina resemble the pulmonate genus Otina , but Velutina are strictly marine. [9] Sometimes they are found out at sea, but usually live among stones near low tide. [9]
