Tellina (Laciolina) incarnata Linnaeus, 1758Tellinoidea : Tellinidae
Slightly inequivalve, RV larger, more convex.
Inequilateral, beaks behind midline.
Ovate, posterior wedge-shaped and curves to the right when viewed from dorsal side. Anterior gently sloping and broadly curved at anterior margin.
Tiny posterior gape.
Sculpture: Fine concentric lines and growth ridges which are very close together on posterior margin and feel rough. LV feels smooth to the touch whereas RV feels rough. Margin: Smooth. Ligament: Prominent, sunken, dark brown band extending less than a third the way to the posterior margin. Hinge: 2 cardinals in each valve. In LV anterior bifid, posterior weak. In RV posterior bifid. 2 laterals in RV, anterior short but prominent, posterior small, below nymph plate. 1 short posterior lateral in LV. Pallial Musculature: Pallial sinus deep, extends upwards two thirds of the way up to below the umbonal region and then slopes downward posterioventrally. It is confluent with the pallial line for most of its ventral length. Cruciform muscle scars visible. Periostracum: Thin, satin. Colour: White/pink/orange/yellow/fawn sometimes with bands. Internal colouration can be more intense and covering more of the shell.
