Remarks

Talassia tenuisculpta   was described from off Madeira; a syntype is shown by Warén & Bouchet (1988: fig. 44; National Museum of Wales). Four additional syntypes are in BMNH (reg. 1875.5.27.29, not seen). The species is distributed from the Bay of Biscay to Madeira, the Azorean Seamounts and Islands and in the western Mediterranean Sea in 21–948 m ( Segers et al. 2009; this study). The outline of the shell is more slender ( Fig. 8 View Figs 1–11 ) than that of T. coriacea   ( Fig. 1 View Figs 1–11 ) and the teleoconch is smooth with numerous growth lines and very fine dotted spiral lines ( Figs 8, 11 View Figs 1–11 ).
