Description
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]
