(Bucquoy, Dautzenberg & Dollfus, 1884)
8m deep, Dramont, Var, S. France. 2,35mm.
« Shell rather solid; spire elevated, turriculate, made up of six convex whorls. Protoconch smooth, the following whorls having a typical sculpture made of interspaced raised longitudinal costae and of two strong decurrent cords, forming two high carinas and a coarse reticulation. The points of intersection are nodulous. On the last whorl, the longitudinal costae abruptly terminate to the level of the summit of the aperture, and the lower part of this whorl bear three strong decurrent cords. Aperture round, peristome thick and uninterrupted. Colour of an even light fawn. Operculum horny, thin, paucispiral. »
« Imperforate, rather solid, turrited, longitudinally ribbed, spirally strongly ridged, the upper ones forming tubercles; whorls six, subcarinate, shouldered, suture deep; aperture margined. » Notice the three spiral ridges, instead of the usual two. This drawing does not match the description, but the latter gives an important feature: the absence of umbilicus.
