« Shell slender, rather solid for its minute size, semi-transparent, and glossy. Sculpture, none. Colour clear white with a faint and irregular tinge of yellowish brown on the body-whorl. Spire long, straight, and rather bluntly pointed. Whorls 6-7, compressed and compact; last whorl (the mouth being placed upwards) forming nearly half the shell ; first whorl semiglobular. Suture slight, but distinct, straightish. Mouth roundish-oval, contracted above, equal in length to one fourth of the spire. Outer lip not very thin. Inner lip conspicuous and reflected. Pillar curved. » – J. G. Jeffreys: “Mediterranean Mollusca N. 3 and other Invertebrata”, Annals and Magazine of Natural History ser.5 vol.11, London 1883, p.398.

On each whorl, the labial scar appears at the same place, in the extension of its predecessor; this feature is an indicia of the genus – a contrario, these labial marks appear randomly in Curveulima Laseron. Left picture: notice the shape of the pillar.
