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
) than that of
T. coriacea
(
Fig. 1
) and the teleoconch is smooth with numerous growth lines and very fine dotted spiral lines (
Figs 8, 11
).
