Phorcus turbinatus, common name the turbinate monodont, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.^[2]^[3]

Description

The size of the shell varies between 15 mm and 43 mm. The very solid and thick, imperforate shell has a conical shape. It is whitish, tinged with gray, yellowish or greenish, tessellated with numerous spiral series of reddish, purple or chocolate subquadrangular blotches. The conoid spire is more or less elevated. The apex is eroded. The about 6 whorls are slightly convex, with impressed spiral lines between the series of blotches, the last generally descending anteriorly. The base of the shell is eroded in front of the aperture. The aperture is very oblique. The thick, smooth outer lip is beveled to an edge. It is pearly and iridescent within. The columella is flattened on the face, bluntly lobed within, pearly, backed by an opaque white layer.^[4]
