« From station 82 (2420m); one right valve. The shell’s stronger concentric stripes, the position of the umbo moved further to the front than in the type specimen [i.e. Axinus flexuosus s.s.], and the lesser arched ventral margin require a separation of this form as a variety of Axinus flexuosus Mont. and also suggest a certain relation to Axinus sarsii Phil., which was only found in the north to this date. » – R. Sturany: op. cit. via Albano, Schnedl & Eschner: Illustrated catalogue of Rudolf Sturany’s type specimens in the NHMW : deep-sea Eastern Mediterranean Molluscs, available here.
