Material examined

GALICIA BANK • 1 spm, 1 sh; 42°56.77′ N, 11°58.53′ W; 1631 m; 2 Aug. 2011; BANGAL 0711 V5; MNCN • 2 sh; 42°41.87′ N, 11°26.71′ W; 1720 m; 8 Aug. 2011; BANGAL 0711 V10; MNCN .

Remarks

The single specimen and three shells resemble Turbonilla paucistriata ( Jeffreys, 1884) , originally described from much shallower depth of the Mediterranean (in the Sicily Channel), but differ in being more slender and having a more distinctly protruding protoconch, also of van Aartsen’s (1987) “ type B” i.e., with coiling axis making an angle of ca 100° with teleoconch axis. Turbonilla amoena (Monterosato, 1878) is also similar but broader. Not much more can be said without additional material from the area.
