« This Pleurotome is elongate, fusiform, narrow, uniformly coloured in dark brown; the spire is longer than the last whorl, sharply pointed at the summit, and made of ten, not very convex whorls, on which run five or six strong longitudinal costae, obtuse, thick and regularly spaced; the whole surface is adorned with very thin striae, radial as well as transverse; the radials are less regular and less marked because they are produced by the growth; the last whorl is rather short, attenuated at the base; the aperture is brown inside, oval-oblong; its right margin is thin, sharp, and shows abapically a large, shallow, subtriangular notch. » – G. P. Deshayes: “Mollusques” in Bory de Saint-Vincent: Expédition scientifique de Morée, Sciences Physiques III, 1, Zoologie, p.177.
