Material examined

MADEIRA • 1 shell (Figs 1–3); off Funchal; depth 70 m; SaM74968.

Remarks

The aperture of the shell is relatively large (about 45% of shell height, Fig. 1) when compared to other NE Atlantic species (typically less than 40%). The spiral sculpture has fine, rugose and continuous ridges covering the teleoconch (Fig. 3). The species is found on the shelf of the Canary Islands, the Salvage Islands, Madeira and the western and northern Iberian Peninsula down to 200 m (Segers et al. 2009; Naturalis 2022). Talassia coriacea has been found sympatrically with T. dagueneti and T. tenuisculpta on the shelf of Madeira (Segers et al. 2009).
