Chlamys (Chlamys) princessae View in CoL ; Rombouts, 1991: 17, pl. 24, fig. 6.

Description: Shell height to 25 mm (averaging ca. 15 mm), elongate, sometimes obliquely oblong, RV slightly more convex than LV, somewhat equilateral, auricles very unequal, umbonal angle ca. 80–85°. Both valves with numerous fine, irregularly spaced, spiny radial riblets, increasing to ca. 45–50 by intercalating riblets towards ventral margin. Intervals microscopically granulated or reticulated in early ontogeny, smooth in late radial stage (i.e. near ventral margin). Anterior auricles with 9–14 fine radial riblets; posterior ones with weaker riblets (6–10). Postero-dorsal margin of hinge line somewhat declivous. Byssal notch small. Active ctenolium with 4–6 teeth. Colour uniformly cream, orange, pink or purple, sometimes also patterned with darker rays or blotches.
