« Colour pattern normally includes brown and orange markings on a brownish, vitreous background. These are commonly accompanied by small opaque-white patches. Most commonly, there are wavy brown flames in a regular pattern, the inflexions of which are aligned along definite spiral zones. These alternate with bright orange patches. Frequently, the brown flames are disrupted into spiral rows of crescent-shaped markings, or into a pattern of small flecks, or combination of either. » – S. Gofas: “The genus Tricolia in the eastern Atlantic and the Mediterranean”, Journal of Molluscan Studies (1982), 48, p.197. – Same spot. 1,1-1,3mm.
